General Information of Cold Rolled Steel Sheet

 

The raw material of cold rolled steel sheet is high quality hot rolled product, and after pickling, continuous rolling, degreasing, annealing, skin pass, slitting and cut to length line etc. Along with it many kinds of new technology and new process of global cold rolling production have been applied. Therefore the quality of the goods could be guaranteed. The finished product has a variety of excellent capabilities, such as processing capability and smooth, flat surface. It’s widely used in outdoor and interior decoration, furnishing manufacturing, home appliance, automobile etc.

Q:How to polish aluminum sheet to be bright?
as for polishing, fine grit sandpaper can't polish it into a mirror,but laser cutting can do it.
Q:why does 10% sulfuric acid not react with aluminum sheet?
10% sulfuric acid has a high concentration and will be passivated and formulate a layer of oxide film after reacting with aluminum,and the reaction will stop after seperating sulfuric acid and aluminum. there is a layer of Al2O3 oxide film on the surface of aluminum, so it's hard for sulfuric acid to break the oxide film and react with aluminum.
Q:Which kind of solution should I use while welding aluminum sheet and copper pipe by tin soldering?
1, you must use over 350W soldering iron, 2,prepare some borax and tin soldering paster, you can’t use rosin to weld it, 3, polish the pipe to clean with fine abrasive paper and borax, 4, put the pipe and sheet into borax, use the soldering trip to rub on the weldment with some borax. 5, after the pipe and sheet become hot, use the soldering iron with the paster and tin to rub the pipe and sheet in borax, then it can be welded. 6, they can be welded together after welding.
Q:How to clean the aluminium oxide on the surface of aluminum? What kind of materials should we use to clean the thin aluminum sheet, and what's the concentration?
you can answer sodium hydroxide solution, dilute acid is useless, aluminum's oxide film is very thick,as for concentration, aluminum will be passivating in concentrated sulfuric acid. if you are high school student,higher concentration is better, you can complete deoxidation by abrasive paper.
Q:Could induction heating fuenace be packaged with aluminum foil as insulation material?
It’s useless. Aluminum foil will generate eddy and emit heat after medium induction, which will reduce the thermal efficiency of medium frequency. Now I provide a method for reference only. Induction coil will be water cooling and is packaged by thermal cement and other materials. Use asbestos sheet and other materials to transform the both ends of induction heating coil as baffle which is mobile and convenient for load and unload. When steel tube is heated in the induction coil, you can put down the baffle to prevent large loss of heat, shorten heat time and improve heat efficiency. When the seamless steel tube is heated into setting temperature, you can open the baffle to conduct expanding process, and you don’t need to think about the thermorytic problem of steel tube in the expanding process. It’s important to shorten the time of expanding process. Baffle is used for heat retaining of medium frequency heating and extrusion forming in our factory. The method above for reference only.
Q:As for graphite and aluminum sheet, which one has a better thermal conductivity?
aluminum sheet
Q:how to distinguish the physical property of copper sheet from the one of aluminum sheet?
physical property: copper sheet: golden, heavy, aluminum sheet: white, light.
Q:Who knows the ceiling size of aluminum hang-parcel?
Size of aluminum buckle plate: general size for home decoration: 300mm×300mm、300*450mm.300*600mm, general size for engineering: 600*600mm、800*800mm、 300*1200mm、600*1200mm. aluminum buckle plate takes aluminum alloy as base and is formulated by rough shape cutting, angle of shear and compression moulding forming. We use various coating to process aluminum buckle plate’s surface, generating aluminum buckle plate products. There are two types aluminum buckle plates: one is integrated aluminum buckle plate for home decoration, another is engineering aluminum buckle plate. With the feature of various colors, good for decoration and good weather resistance, aluminum buckle plate is broadly used for outdoor wall decoration, indoor top grade home decoration and advertisement decoration,etc.
Q:is aluminum foil spacer poisonous after heating?
It’s a kind of thermoprint material made by pressing the aluminum into sheet, and owing to its similar thermoprint effect to silver foil, so it’s called fake silver foil. Aluminum has soft texture, good ductility, and is silver white, if we use sodium silicate to paste the sheet after pressing on the offset paper, making aluminum foil, the foil can be printed. But aluminum foil is easy to be oxidized and darkens, rubbing and touching will make it darken, so it doesn’t suit for the thermoprint of books’ cover that needs to be preserved for a long time.
Q:does aluminum sheet need to conduct ROHS detection?it's metel material, how much detections should it conduct for ROHS detection?
It's ok for detecting four items of ROHS heavy metal for ROHS detection of metal material.
