Difference of Cold-rolled aluminum and hot-rolled aluminum

"Cold-rolled aluminum" refers to the aluminum industry, "casting aluminum alloy", which is mainly aluminum - silicon, or add some alloying elements for casting molding, the products are castings. Surface roughness of aluminum products, mostly raw aluminum. Raw aluminum is not pure aluminum, it and pig iron, hard to knock on the broken. "Cooked aluminum" is "deformed aluminum ...
"Cold-rolled aluminum" refers to the aluminum industry, "casting aluminum alloy", which is mainly aluminum - silicon, or add some alloying elements for casting molding, the products are castings. Surface roughness of aluminum products, mostly cold-rolled aluminum. Cold-rolled aluminum is not pure aluminum, it and pig iron, like a knock on the broken hard.(aluminium plate 20mm thick)
"Hot-rolled aluminum plate" is "deformed aluminum alloy", the international seven alloy series, namely: 1 series - pure aluminum, 2 series - aluminum copper, 3 series - Al-Mn, 4 series - Al-Si, 5 Series - Al Aluminum, aluminum, aluminum foil, etc. are deformed aluminum alloy category, the processing deformation of forming, which include pure aluminum and aluminum alloy, Aluminum alloy; "alloy" not a class, aluminum products include pure aluminum and aluminum alloy products. "Cold rolled aluminum" and "hot rolled (marine aluminium plate)aluminum" are now called "cast aluminum" and "deformed aluminum". The so-called "scrap aluminum" refers to the use of waste into the market after the various aluminum materials, aluminum scrap on the market in addition to the "cold rolled aluminum" (that is, high silicon) and "hot rolled aluminum" , Pay attention to strictly according to alloy composition class use. aluminium plate in coil

The standard method of welding aluminum! Aluminum Suppliers

Welding method:
Almost all kinds of welding methods can be used for welding aluminum and aluminum alloys, aluminum and aluminum alloy but with different adaptability to a variety of welding methods, various welding methods have their respective applications. Gas welding and arc welding methods, devices, simple and easy to operate. Welding can be used for less demanding welding quality aluminum sheet and castings welding. SMAW welding aluminum alloy castings can be used. Inert gas welding method is the most widely used method for welding aluminum and aluminum alloys. Aluminum and aluminum alloy sheet can be tungsten or tungsten AC TIG pulse welding. Aluminum and aluminum alloy plate can use tungsten arc welding helium, argon-helium mixed gas tungsten arc welding, MIG welding, pulsed MIG welding. MIG welding, pulsed MIG welding is widely applied, before welding preparation.(3003 h14 aluminum)
Clean up before welding:
1, aluminum and aluminum alloy welding, welding should be strictly removed before oxide film and the oil and the workpiece weld wire surface; clean up after such long time storage, reprocessing.(aluminum floor plate sale)
2, plate: aluminum at low temperature strength, good flow properties of liquid aluminum weld metal during welding prone to staying phenomenon. In order to ensure penetration but will not collapse, welding often used to hold the plate and around the metal bath. Pad can be graphite plate, stainless steel, carbon steel, copper, or copper and the like. Surface of the pad to open a circular grooves, in order to ensure that the weld negative shape. May not add side welding plate forming, welding operation but requires skilled arc welding or take strict energy automatic feedback control and other advanced technological measures.
3, preheat: thin, small pieces of aluminum generally do not preheat thickness 10 mm ~ 15mm preheat time can be, depending on the type of aluminum alloy preheating temperature can be 100 ℃ ~ 200 ℃, available oxygen a acetylene flame, furnace or other heating blowtorch. Preheat weldment can reduce distortion, reduce porosity and other defects. After the welding process.(aluminum alloy 5052)
Stay clean up after welding and seam welding in the vicinity of the residual flux and welding slag will destroy the aluminum surface passivation film, sometimes corrode aluminum parts, should be cleaned. Simple shape, the general requirements of the workpiece can be a simple way with hot water or steam blowing scouring brush to clean. Demanding and complex shape of aluminum parts in hot water after brushing with a stiff brush, and then at about 60 ℃ ~ 80 ℃, concentration of 2% to 3% aqueous solution of chromic acid or potassium dichromate solution immersion 5min ~ 10 min, and scrub with a stiff brush, then washed in hot water washing, drying oven or with hot air drying, can also be dried naturally.
Post weld heat treatment of aluminum containers generally do not require post-weld heat treatment.

solve the problem of aluminum alloy surface crack

Aluminum alloy flat ingot casting surface crack is a common defect.Aluminum alloy surface crack problems of semicontinuous casting process should consider many factors:
Mold taper;
Casting temperature '
Casting process slag
Melt Overheating;
Casting process too fast
cooling system
Alloy chemical composition
Skills

Aluminum alloy flat ingot surface crack of solution:
The key to solve this problem to consider three main links:
Is the varieties of alloy chemical composition control
Varieties of casting process is alloy.
Is operation skills and natural conditions.

The crystallization of aluminum alloy is also called the condensing tank, play a decisive role for casting.Aluminum alloy changes of taper of mould for casting can not be ignored.Taper of mould is too large flat ingot casting surface segregation tumors will increase, once the operation is not good will surface cracks, slag generated again when too narrow casting slab ingot mould can produce the surface cracking.A good teacher will adjust the size of the mould, casting to prevent flat bursts in the casting surface crack.
Aluminum alloy flat ingot surface crack for cooling water is very important.Cooling water is distributed evenly, bedding face and small surface strength, water size, water temperature are very big influence on solid-liquid region.
To sum up, the aluminum alloy flat ingot surface crack is made one of the common defects in the process of melting, eight analysis reason should be attention in the process of casting, will be the fault to ignore every detail, loss and waste.The control problem of alloy composition and impurities as well as the process setting need to be studied according to different environment analysis, make accurate judgment.For example: the surface of the aluminum alloy flat ingot slag smelting operation again in one of the most cause of surface crack.Majority is caused by improper operation, such as furnace temperature control - water - speed - flow disk horn mouth whether level off - crystallizer liquid surface height, there is every detail such as the operation.In order to prevent the happening of the aluminum alloy flat ingot surface crack phenomenon.From semi-continuous casting to the fully automatic casting, such as: automatic internal quality of casting defects is a new topic.For example: plume crystal column crystal. The vertical tree. Shining crystal column and prevention, such as we will continue to study and explore.
