[font=宋体]Industrial furnaces often involve heating processes such as smelting, drying, baking, and chemical reactions in their production processes. The industrial furnace is the heating equipment used for these processes. The fuels that provide heat sources for these devices mainly include gaseous fuels, liquid fuels, solid fuels and electricity. The use of these heating equipment is prone to burns and electric shock accidents. If gas or liquid fuel is used, it may also constitute a fire and explosion hazard in the event of leakage or spillage.Gear Vacuum Heat Treatment Process[/font]
[font=宋体]When the industrial furnace is used, the furnace door lifting mechanism must be in good condition, and the broken wire of the wire rope must not exceed the specified value. The heavy hammer is properly configured, and the exposed transmission part should be provided with a protective cover. If it is a water-cooled furnace door, it is necessary to ensure that the pipeline is unblocked, and the pipeline is not frozen in winter. The furnace door should have a limit device. When entering and leaving the furnace, there should be an interlock device to cut off the power supply. The number of broken wires in the wire rope should not exceed 10% within the pitch. The weight suspension of the balance furnace door should be reliable. It is required that the protective device of the exposed transmission part should maintain the correct installation position and the structure is reasonable. The wire rope pulley of the furnace car should be intact. All pulleys and sprockets on the kiln are well-structured, free of defects, and rotate flexibly.High corrosion resistance aluminum alloy brazing sheet and its vacuum heat treatment process news[/font]

Aluminum door frames should be fabricated after measuring actual size of opening. The side legs of frame should be 50 mm more in length so that they can be embedded into floor. The frame of door should be manufactured by reducing 25 mm width and by keeping the height 37.5 mm, more than opening i.e. (50 -12.5 = 37.5) because 50 mm length is required for embedding in floor.

Aluminum door is a solid barrier fixed in door way or opening in a wall. It consists of two parts i.e. frame and shutter and can be opened for access to and from buildings, between rooms or be closed for privacy. A variety of doors such as wooden doors, iron doors, PVC or plastic doors and aluminum doors are available in the market. Now a days aluminum doors, windows and glazing are widely used.
Materials of aluminum door
Aluminum alloy standard extruded sections are used for fabrication of aluminum doors. Chemical composition and mechanical properties of these extruded sections should comply with requirements of IS: 733, IS: 1285, IS: 737.
Anodizing aluminum doors
Aluminum is anodized by manufacturing units with the help of anodizing/electro coating plants. It should be uniform without color variation. The outer surface of aluminum members is anodized up to 30 microns in different colors like silver, champagne, bronze and black. A foolproof scaling system ensures durable finish for long lasting applications. The anodizing should be as per ISO 9002.

| How to Successfully MIG Weld Aluminum |
|

Keep in mind these important factors when MIG welding aluminum for your application.
Tips for getting started
Consider material thickness: Material thicknesses of aluminum that can be MIG welded are 14 gauge and heavier; the output capacity of your welder determines the thickness you can weld. To MIG weld aluminum thinner than 14 gauge (.074 inch), it may be necessary to use specialized pulsed MIG or AC TIG welding equipment.
Keep it clean: Aluminum should be thoroughly cleaned prior to welding, including the removal of any lubricants from the material. Oxide removal should be done after degreasing using a stainless wire brush — either a hand wire brush or a cup wire brush will work. If a power wire brush is used, keep the rpms and pressures low to reduce smearing the surface of the material, which could entrap oxides and impurities under the surface. To avoid contaminating the base material, always clean with a wire brush that is used on aluminum only.
Choose the right gas: Because aluminum is a non-ferrous metal, it requires a 100 percent argon shielding gas. Flow rates of 20 to 30 cubic feet per hour are recommended.
What process should you use? When MIG welding aluminum, the desired mode is spray transfer. This process is a very smooth transfer of molten metal droplets from the end of the electrode to the molten pool. The droplets crossing the arc are smaller in diameter than the electrode. There is no short-circuiting in spray transfer, and the deposition rate and efficiency are relatively high. However, be aware that spray transfer involves a high amount of heat, creating a large weld pool with good penetration that can be difficult to control. It should not be used on materials thinner than 14 gauge.
Gun and wire feeding options: Choosing a gun and wire feeding system is an important step before MIG welding aluminum. Aluminum wire is commonly fed with a spool gun or with a push-pull system. Spool guns improve feeding of soft wires by locating a small pool of wire on a pistol-grip style gun. Using a spool gun eliminates the possibility of birdnesting because the wire only feeds a few inches. With a push-pull system, a motor in the gun pulls the wire through the liner, while a motor on the feeder acts as an assist motor. This option is ideal when welding far from the power source and can be more ergonomic and user-friendly.
