| What happens when iron is placed into aluminium sulphate solution? |

Aluminum sulfate solution has strong acidity. If stainless steel buckets are used for a long time, stainless steel barrels will be corroded. It can be thought that the reaction between stainless steel barrel and aluminum sulfate is chemical reaction.
Hydrolysis of aluminum sulfate can produce sulfuric acid, and sulfuric acid and iron react to form ferrous sulfate, which causes the stainless steel barrel to be corroded.
Al2 (SO4) 3 + 6H2O = 2Al (OH) 3 + 3H2SO4.
Fe + H2SO4 = FeSO4 + H2
Other components of stainless steel barrels, such as chromium and nickel, can also react with sulfuric acid and be corroded.
When heating, the hydrolysis intensifies the acidity, and the rate of chemical reaction increases, and the corrosion rate accelerates greatly.

In general, in the use, the mechanical properties and the mechanical performance requirements are not high, so the quality of the aluminum tread plate is mainly about the pattern rate, pattern height, pattern height difference. Currently the available thickness is 2.0-8mm on the market, the width is 1250,1500 mm. And for special places (such as the places need to vacant, or in the high corrosion degree, or easy to rust and corrosion), 5052 or 6061 anti-rust anti-skid aluminum plate is recommended to use, the series of non-slip aluminum has great performance of anti-rust, corrosion resistance. For the vacant place, the staff need to step on it, the proposed use is alloy series, while the thickness is not less than 6.0mm, the series and thickness of the non-slip aluminum plate to keep the safety of staff maximize, while ensuring the life of non-slip aluminum plate.

Exact knowledge of the surface roughness and thickness of the oil layer provides pressing plants in the automotive industry with enormous potential in terms of reducing their waste and enhancing process reliability before continuing to process aluminium strip or plate material. The oil layer measurement, however, has specific requirements. The trend is towards higher strength material with thinner oil layers, which, overall, means enhanced requirements for the pressing process in terms of accuracy. Due to the close relationship between the oil layer and material roughness, as well as the significant influence they have on the forming process, e.g. for the automobile manufacturer, accurate monitoring and control of both factors during production of the strip will provide the aluminium manufacturer with an important competitive advantage.
[img=300x0]http://www.aluminiumstrip-hm.com/wp-content/uploads/2017/04/aluminum-strip-14-300x300.jpg[/img]
Standard measuring methods that are used in the production of aluminium stripmaterial are based on the use of handheld devices. The accuracy of this approach is extremely limited and prone to errors, particularly due to the low statistical significance of the individual measurement (point measurement) and the human factor. These limitations are overcome with the introduction of the EMG SORM3plus and EMG SOLID® online measuring systems, which are also suitable for the aluminium production process. EMG SORM3plus is a laser-based online roughness measuring system, which delivers online values for Ra and Rpc in a quasi-continuous manner at production speeds of up to 2400 m/min.
The EMG SOLID® system, which is based on infrared spectroscopy and used for continuous online measurement of the oil layer, is suitable for use on uncoated and pre-treated aluminium strip material and can be used for a wide variety of lubricants (mineral oils, thixotropic mineral oils, dry-film lubricants/dry lubes).
In addition to providing online measurement data and enabling the operator to intervene immediately in the process to prevent variations in quality and complaints, both systems also provide valuable historical data that can be used for trend analysis, statistical process optimisation and the verification of process models.
By combining these systems, the aluminium manufacturer is able to generate data consistently throughout the process chain, thereby enabling the production of individual plate material to be replicated exactly in the downstream processes. The data cannot only be used for subsequent error analysis, but it can also be used in the future for targeted control of presses and post oiling systems in the pressing plant. This is, at the very least, potential that can be derived from the industry-wide activities conducted in the context of the Industry 4.0 paradigm.

Aluminum foil flexible pipes can deliver all kinds of media of temperatures between -50℃ and 150℃. They are applied in heat or cold maintaining projects for centralized heating, central cooling and hot oil delivery in industries like petroleum, chemical, coal, refrigeration and heating supply. Although you may have caught sight of the pipes a lot in daily life, you might not pay enough attention to their structures.
![[Image: 1-1P420160011a5.jpg]](http://haomei-aluminium.com/uploads/allimg/180420/1-1P420160011a5.jpg)
Generally speaking, an aluminum foil flexible pipe consists of four parts: delivery tube, heat preservation layer, protective shell and alarming lines. There are different types of delivery pipes in accordance with technical requirement for medium to be delivered. A pipe may be equipped with delivery tubes of seamed steel, seamless steel as well as helical welded steel with submerged arcs on both sides. Heat preservation layer normally adopts hard polyurethane foaming plastic as raw material. It has necessary strength and flexibility. Besides, foaming plastic with air inside shows perfect heat maintaining property. The protective shell of an aluminum foil flexible pipe is made of high-density polyethylene or fiber glass which conducts heat less quickly than metals, thus heat can be preserved more efficiently. Alarming lines have been embedded in the heat preservation layer near steel tubes during the production of high temperature insulation tubes for direct burial. In case of leakage of delivered medium, the alarming line will send signals to a special measuring instrument. At the same time, leakage location and scale will be displayed on the instrument so that maintenance workers would be able to deal with the problem quickly.

The main alloy element of 6061aluminum plate is magnesium and silicon, with moderate intensity, good resistance to corrosion, excellent oxidation effect. 6021 aluminum plate is widely used after heat treatment, for automated machinery parts, precision machining, all kinds of mold manufacturing
.![[Image: aluminum_plate-2-300x225.jpg]](http://www.aluminiumstrip-hm.com/wp-content/uploads/2017/03/aluminum_plate-2-300x225.jpg)
T6 state of 6061 aluminum alloy is the most used, forming process including medium thickness plate quenching, medium plate section, drawing machine, aging treatment, sewing machine, polishing, packing.
The whole production cycle isabout 10 days. After heat treatment, It doesn’t need to be cold, but can be straightened, leveling,not affecting the mechanical properties.
F state is freedom of 6061 aluminum alloy processing, applied to the process of forming, the strain hardening and heat treatment conditions of special products.F state production cycle is short: medium thickness plate section, sewing machine, polishing (also is not polished, according to customer’s requirement) – packaging, the entire process to arrange 3 days can be shipped smoothly. F state mechanical properties do not have strict specifications, customers according to their own needs can be heat treatment processing, the F state again the state into production use. Corresponding to the price is the cheapest.
O state is to obtain the minimum strength of 6061 aluminum alloy after annealing completely processed products, applied to the 6061 aluminum alloy sheet under 8.0mm. Its production process: cold rolling thickness – bent proper cleaning – full annealing – fly shear piece of stretch bending pose (or out of the finished product) – packing warehousing and so on a series of production, production cycle after T6 state.
haomei aluminum 6061 aluminum plate is applied widely with excellent performance, welcome to inquire.
