Aluminum sheet smelting process must have a sufficiently high temperature to ensure that aluminum alloy and other metal elements melting and dissolved sufficiently, the heating temperature is too high, the melting speed faster, but also make mutual harmful action metal with the furnace gas, lining and so reduce the time . Practice shows that rapid heating to accelerate the melting charge,shorten the melting time, to improve productivity and quality are beneficial.
How to Control the Temperature of Aluminum Plate During Melting?
But the high temperature prone to overheating, especially in the use of flame reverberatory furnace heating, gun charge in direct contact to the intense heat is applied to the molten or semi-molten metal, prone to gas invasion melt. Meanwhile, the higher the temperature, the reaction interact with the metal furnace gas, the lining also be faster, it will cause metal loss and decrease melt quality. Superheated gas absorbs not only easy, but also easy to make the grain structure in the solidified ingot thick, increasing propensity ingot cracks Alloy. Therefore, in the smelting operation, should control the melting temperature of the melt to prevent overheating.
Aluminum sheet in actual production, it is necessary to prevent overheating of the melt, but also to accelerate the melting, melting time shorter. Control the melting temperature is extremely important. Most plants are using flash after feeding high-temperature rapid melting, so that in a semi-solid, semi-liquid state of metal shorter time when exposed to intense flame furnace gas and reduce the oxidation of the metal, burning and reduce melt suction gas. When a layer of liquid metal after the charge level, in order to reduce local overheating of the melt should be appropriate to reduce the melting temperature, and to strengthen the agitation in order to facilitate the melt in the smelting process of heat conduction.

Aluminum foil is made of aluminum sheet from direct rolling, because the effect of the short-run effect and it is similar with pure silver, so it is called fake silver foil.Aluminum foil has good performance, surface safety and sanitation, acid and alkali corrosion, with long-term preservation, so it is used in some food packaging, pharmaceutical packaging, etc.Especially in the beverage, barbecue, snacks and other packaging, food packaging aluminum foil application is the current main direction.Then is food packaging aluminum foil is absolutely safe?
Is Food Packaging Aluminum Foil Safe?
Aluminum foil has elegant silver luster, it can be moisture, air tightness, light shading, wear, non-toxic, tasteless, and therefore it is the current green, environmentally friendly food packaging materials. In particular, when aluminum foil, plastic and paper are composite, the food can be well preserved from outside of the light, wet, gas, etc.Especially for food cooking packaging, if we use such material, at least, it can ensure that the food not bad for more than a year.Moreover, the heating and the package are very convenient, so it is welcomed by consumers. To heat the milk in winter, , for example, some office workers or students will heat milk as breakfast, however whether the aluminum in the foil packaging will not enter the milk or not, we shall have a look at the test data.
First, experts go to pick up three kinds of milk for sampling, respectively, to take 3 ml into the test tube.Then three kinds of milk were heated to 50 degrees Celsius, then take 3 ml into the test tube.It was found that there was no change in the content of protein in three kinds of milk.Subsequent analysis of the aluminum element, the results showed that after heating the milk aluminum foil did not release the aluminum,That is to say, the aluminum foil food packaging of milk and other food packaging is absolutely safe, after heating will not cause any harm.Therefore, refer to the current packaging materials, food packaging aluminum foil is the most safe, green, environmentally friendly new materials.
Food packaging aluminum foil is safe and environmental protection, can be recycled packaging materials, the production process has been more mature in China, most manufacturers are able to meet the production standards. As a consumer, it is not necessary to worry about the safety of packaging aluminum foil.

Thickness of aluminum sheet, refers to in the following more than 0.2 mm to 500 mm, width over 200 mm, the length of the aluminum material called aluminum sheet within 16 m, can also be referred to as the aluminium material.
How to Calculate the Aluminum Sheet Price?
Aluminum sheet classification there are several ways of common classification method is points, according to the thickness of the sheet can be divided into 0.15 2.0, conventional plate (2.0 6.0 mm), medium plate (6.0 25.0 mm), plate (25-200 - mm), super thick aluminum sheet (200 mm) above.
From the process, aluminum sheet refers to use aluminum rolling processing of rectangular plate, can be divided into pure aluminum sheet, aluminum alloy, aluminium sheet, thick aluminum sheet and decorative pattern in the aluminum sheet.
So, different thickness, different alloy aluminum sheet is how to price, we are in the market to buy aluminum sheet should be how to choose?Let's understand the aluminum sheet price of several basic steps:
1, first make sure that the requirements of aluminum sheet size, thickness, width, length, etc. The specific data.When computing unit meters shall prevail.
The density of aluminum, aluminum volume * 2 (2.71), namely the length * width * thickness * 2.71, figure out what is the weight of each aluminum sheet (tons), and then multiplied by the number of aluminum sheet, such as 300, 500, the result is the total weight of this batch of aluminum sheet.
3, understand the current market price of aluminium ingot, this can be from chinalco network or Shanghai non-ferrous web sites such as to check the price changes every day.Contact aluminum processing enterprises for inquiry, consulting relevant models aluminum sheet how much is the processing fee per ton, different alloys have different processing, the difference is bigger.
4, the price of aluminum ingots, plus processing production enterprise of this product, this is the type of aluminum sheet the accurate price per ton.
5 tons, the required products, multiplied by the per ton aluminum sheet prices, is the product of the accurate quotation.
With our 500 8 mm thick, 60 mm wide and 1200 mm long, aluminum sheet, for example, we can calculate the weight of the products is: 0.08 * 0.6 * 1.2 * 1.2 * * 500 = 2.71 tons.
If on the day of the aluminium ingot price is 10000, aluminum companies for the processing of the alloy is 5000 per ton, so aluminum manufacturers offer to you is (10000 + 5000) * 7.8 = 117000 = 117000.

What kind of types the transformer aluminum foil has in our life?
Transformer aluminum foil is one of the most important materials of transformer winding manufacturing, which influences the quality of the transformer directly. First of all, let us learn what the transformer is. Transformer consists four parts which are winding and iron core, fuel tanks and insulating casing. The main part is winding and iron core (body), winding is the electric circuit of transformer and iron core is the magnetic circuit of transformer. The two forms the core of transformer - electromagnetic part.
Transformer aluminum foil and strips is generally selected 1060, 1070 and 3003 aluminum plate to be the material, which are belong to the conventional series among the aluminum family. 1 and 3 series belong to the ordinary aluminum plate, and the aluminum foil with the thickness between 0.02 and 0.055 mm are used for transformer. As transformer aluminum foil process is a single and with relatively mature technology, it has the advantage of price relative to the 5 and 6 series products. Generally 5 and 6 series products belong to high-end products with the complex production process, high quality of the product, good elongation and tensile strength, the transformer aluminum foil can completely satisfy the requirement of the conventional processing (stamping, stretch).

Currently, the industry commonly used aluminum coloring natural coloring, electrolytic and chemical coloring coloring and resin powder coating method.
Aluminum chemical coloring is called dipping coloring, which is early for anodized aluminum coloring methods. Chemical mechanism is based on a porous film like woven fabric as dye adsorption capacity, the dye in the water into a single molecule separated, coloring, the dye is adsorbed to the surface of pores in the pore diffusion, accumulation, and alumina and a chemical or physical action leaving the colored film, by sealing treatment, the dye is fixed within the pores.
Aluminum chemical coloring process is simple, high efficiency, low cost, less investment in equipment, coloring domain wide, bright color, and so on. However, a large area of products prone to uneven color, coloring after cleaning, improper sealing or mechanical damage, it is easy to fade, poor light fastness of the colored film, it is generally used as interior decoration, with a small aluminum products daily coloring treatment.

Different industries and production process have different requirements for aluminum sheet in mechanical property, so it will require aluminum sheet manufacturers to have strengthening treatment in the process of production of aluminum sheet. At present, there are two mainstream methods to strengthen aluminum sheet in aluminum industry: it is strengthening in product process and solid-solution to strengthen the aluminum sheet.
How to Strengthen the Aluminum Sheet
1. Strengthening in Aluminum Sheet Processing
Strengthening in product process is also called the cold hardening, it is means aluminum sheet below the recrystallization temperature and experience cold deformation processing such as forging, rolling, drawing, or stretching. When process in cold deformation, aluminum sheet’s internal dislocation density will be increase, and entangled with each other and form the cellular structure, which will hinder dislocation motion. The greater the degree of deformation dislocation tangles, the greater the deformation resistance, the higher the strength will increase. After the cold deformation, the degree of strengthening is different according to different deformation degree, deformation temperature and the properties of the material itself. Cold deformation under the same material at the same temperature, the higher the degree of deformation, the greater the strength, but plasticity is lower.
2. Solid-solution to Strengthen the Aluminum Sheet.
Add some alloy elementS in the pure aluminum to form an infinite solid solution or limited solid solution, which not only can obtain high strength, but also can obtain excellent plasticity and good pressure processing performance. In generally, the most commonly used alloying elements in aluminum solid solution strengthening are copper, magnesium, manganese, zinc, silicon, nickel and other elements. aluminum sheets are generally formed limited solid solution formation, such as Al-Cu，Al-Mg，Al-Zn，Al-Si，Al-Mn snd other binary alloy formation of solid solution, and they all have larger limit for solubility which can have effect of larger solid solution strengthening.
Strengthening aluminum sheet, the strength performance will be improved obviously , but its hardness could not have been promoted again; When reach the maximum hardness, no matter what method, it cannot continue to improve the hardness of aluminum sheet, and it has to choose other temper with higher base hardness..

Aluminum sheet refers to aluminum materials with thickness from 0.2 m to 200mm and length within 16000 mm. However, aluminum sheet with thicker thickness is also called aluminum plate. There is almost no different between prices of aluminum sheet and plate if only considering their thickness. Generally speaking, aluminum sheet can be divided into pure aluminum sheet, alloy sheet, thin aluminum sheet, thick aluminum sheet, aluminum tread plate, etc. aluminum sheet prices of these products are a little different according to their processing technology. So many different specifications, then how can we calculate the prices of aluminum sheet? As an aluminum manufacturer, haomei Aluminum will explain the method to calculate prices of aluminum sheet. Here are some factors that influence prices.
How to Calculate the Prices of Aluminum Sheet?
1. Prices of Aluminum Ingots
Aluminum sheet is made from aluminum ingots into sheet or plate. Thus, the prices of aluminum ingots have a great influence to the price of aluminum sheet. We all know that price of aluminum ingots varies from day to day, thus, therefore, the prices of aluminum sheet also varies day to day. If the price of ingot is 10960RMB in yesterday, but today is 9900RMB, then prices of aluminum sheet today reduced by 1060RMB per ton. So if you buy aluminum sheet today, the price is much cheaper.
2. Processing Fee
prices of aluminum sheet are different if the alloy number is different. Even in the same series number, products with different tempers and specifications have different prices. Besides, even the same products may have different prices in different manufacturers. This has something to do with the production capacity, product quality as well as other fees. haomei aluminium is a listed company with large scale. The raw materials of haomei aluminium have high quality to guarantee the quality of final products. Advanced equipments also guarantee the stable properties and accurate technologies.
3. Dlivery Fee
For aluminum industry, delivery is an important part in sale. The distance of destination, amount of goods and other factors can infect the final delivery fee. Thus, prices of aluminum sheet can also be infected. haomei aluminium. has its own delivery system to guarantee fast delivery and low cost. These are three main factors that ca influence the prices of aluminum sheet, however, other small factors can also cause the difference of prices.

Rinse with plenty of water from the surface of the plate to start, use wipe board impregnated with detergent diluted with water, soft cloth gently.
How to Clean the Aluminum Sheet
Plenty of water and then rinse the plate surface, the dirt away, check the board for no clean place to wash with detergent focus. Rinse with water board, until all the detergent to wash away.
Do not wash the hot plate surface, the temperature more than 40 degrees, the evaporation of water will be too harmful to the plate surface paint. Be sure to note that the appropriate choice of detergent is best to use a neutral detergent, do not use strong alkaline detergent, usually some potassium hydroxide, sodium hydroxide or sodium carbonate, strongly acidic detergents, abrasive detergent and paint detergent solubility.
