Production Flow of Hot Rolled Checkered Steel Plate with Best Quality:

1.The steel raw materials are first melted in an electric furnace. They are subjected to at least 12 hours of intense heat.

2.The mixture is cast into either large rectangular blooms, slabs or bar-like billets, before taking on a semisolid form.

This initial form of steel is then processed via forming operations that include hot rolling into bars, wires, plates and slabs.

3.The steel is subjected to annealing. This is a heat treatment in which the metal is first heated and then cooled under extreme, controlled conditions. The metal is thus treated for internal stresses and is duly softened and strengthened. This processing is also referred to as 'age hardening'. It requires careful monitoring of temperature and heating and cooling times. The aging temperature affects metal properties massively; while lower temperatures cause high strength and low fracture toughness (i.e., more brittle than ductile), higher temperatures result in a tougher material of lower strength (i.e., more ductile than brittle). Rapid cooling can produce a tough steel with no significant loss in strength. The heat treatment given to stainless steel depends on the type and grade of steel being produced.

4. Annealing or the heat treatment can lead to the development of a precipitate, known as scale. The scale can be removed via several methods, such as pickling, (nitric-hydrofluoric acid bath),electrocleaning(application of an electric current, using phosphoric acid and a cathode), etc.

5. Descaling of the material is introduced into the manufacturing process at different times, depending on the type of steel being produced. While the bar and wire forms have to be additionally treated with hot rolling,forging and extruding, the sheet and strip forms go through annealing after hot rolling.

6. Cutting operations in the manufacturing process are essential in obtaining the desired shape and size of the end product. Mechanical cutting involves the use of guillotine knives and high-speed steel blades for blanking (punching out the shape by shearing) and nibbling (cutting out a series of overlapping holes). It is also cut via flame cutting, a process that involves the use of a flame generated by oxygen, propane and iron powder. The plasma jet cutting method uses an ionized gas column to melt and cut the metal.

6. Manufacturing end products involve further shaping via heat-rolling, pressing, forging and extrusion. The material is then joined via welding and given the desired shape.

Q:Find a weld and riveting machine to connect the two roll of aluminum together. the width of aluminum is 40-60cm,because the surface of aluminum has a layer of oxidation film,so...
I am a high voltage professional welder. I can't endure the current surge,even the spot welding. the surface oxidation film can be baked by the cutting knife,or polish by the abrader. no matter how big the welding rod is useless.The aluminum is too thin.
Q:As for the use of aluminum foil paper,which side is the front side?which side do we use when using the baking oven?
The non-bright side is used to wrap the food while the bright side is used to spread over the plate.
Q:What specification does air hose of aluminum foil have?
XPS composite duct is taking stereoplasm B1-level flame retardant poly ethylene foam as insulating layer. Double-sided embossed aluminum foil is a new composite product through one-time processing. The product quality is light, beautiful and suitable for decoration and some requirements on high-grade places. It is convenient for installation and maintenance. It's innocuous and unpoisonous and with high-pressure resistance, dampproof, air proof, low heat conductivity coefficient and long-time heat insulation performance. It can also provide a maximum ceiling height. It has a high space utilization and is an economic product that is encironmental and healithy.
Q:Whether aluminum tape has conductivity of heat?
It is of performance of heat conduction but is relatively lower, mainly because that aluminum tape is glue.
Q:What's the aluminum foil coiled material?
Metallic aluminum foil is characterized by moisture resistance, air tightness, thermal insulation, ultraviolet ray resistance, wear-corrosion resistance, etc. Made of aging-resistant butyl rubber, the self-adhesion layer is strongly cohesive.
Q:Aluminum foil insulation material
Aluminum foil composite material: some sound insulation storefronts paste such products under the hood to protect the paint of hood. Due to the high reflection performance of aluminum foil on heat (can reach above 95%), sticking the aluminum foil composite materials can make most of the heat coming from the engine be reflected back to the engine itself and the surrounding lines. Although it effectively protects the paint, it is not conducive to long-term stable working engine since it accelerates the aging of the engine compartment lines,and easy to cause safety problems. In addition, with the aluminum foil composite material is usually not waterproof design, the rain or car-washing also brings body with burden. Good hood protective equipment should be heat insulating, flame retardant and waterproof design. It would be better if it can have sound insulation and sound-absorbing effect. It will be great if its appearence is dark color. The right use of aluminum foil in the car,for example: using the high reflection characteristics of hot, making it into car sun shade or exhaust pipe heat shieldcomposite after being compounded with other materials.
Q:What's the difference between the cold stamping molding aluminum foil and common aluminum foil package
The technological process is determined by the type of metal, size,quality requirement,production and the producing equipment size,production capability.the characteristics of medical aluminum foil are as follow:1.the machinery character can meet the requirement of the use. Its softness makes it easy to process.2. the light weight is helpful to reduce the cost of the transportation.
Q:Can aluminum foil insulate heat?
Different countries due to differences in levels of economic development, the consumption structure of aluminum foil big gap. In European and American countries, foil products for packaging 70% of total demand. In the Chinese market, aluminum foil is mainly used as industrial raw materials, manufacturing, packaging, aluminum foil only 30% of total domestic demand. Although aluminum foil packaging development late, but the market is growing rapidly, the prospects attention.
Q:Can aluminum foil be put in microwave oven?
No. The microwave produced by the microwave oven belongs to radio wave frequency band and is about 2500MHz. The features of this frequency band are as follows: 1) It can be absorbed by food and water to make the molecular react violently so as to produce heat. 2) It cannot be absorbed by plastic, ceramic and glass. 3) Metal can be conductive to electricity under the influence of the electric field of microwave. Since thick metal can resist the electric field of microwave and reflect microwave, the inner wall of microwave oven is made by thick metal. Similarly, putting a thick metal container in the microwave oven will make the metal container reflect microwave and thus make the food unheated. However, the electric conduction of thin aluminum foil may cause disastrous reaction. In the course of electric conduction, the temperature of thin metal will rise to cause a fire. At the same time, when met with heat, aluminum foil will shrink and its point will produce sparks which may ignite the combustibles in the oven.
Q:What defects may causes through the aluminum foil roll?
All the rolls can cause surface damage factors, can be formed on the aluminum foil rolling harm. Because aluminum foil rolling roll surface finish high, slight gloss surface unevenness will affect its status. Periodically clean mill, mill kept clean, to ensure the normal operation of roll clearance, roll change periodically, reasonable grinding, it is to ensure a uniform surface substantially aluminum foil rolling conditions.
