There are many aluminum sheet manufacturers and the level is uneven. The manufacturers that can produce high-quality aluminum sheets are rare. So, before asking the 1100 aluminum sheet price, we’d better know about the product quality first. The quality of 1100 aluminum sheet is affected by the manufacturing process directly. The so-called aluminum sheet manufacturing process is a process of aluminum alloy into single-sheet or coil-shaped material having a rectangular cross section by processes such as smelting, ingot casting, various pre-rolling preparation, flat roll rolling, heat treatment and finishing. But to make qualified 1100 aluminum sheet product, considerable skills are needed.
1: aluminum and aluminum alloy sheet strips are supplied in hot rolled state, annealed state, various grades of soft state and various heat treatment states.
2: preparation before hot rolling mainly includes ingot quality inspection, soaking, sawing, milling, aluminum coating and heating.
3: the cooling rate is high during semi-continuous casting, the diffusion process in the solid phase is difficult, and the chemical composition and organization unevenness are easily formed inside the ingot, such as intragranular segregation, so that the plasticity is lowered.
4: when there are defects such as segregation, slag inclusions, crusting and cracks on the surface of the ingot, the surface should be milled, which is an important factor to ensure good surface quality of the 1100 aluminum sheet.
5: hot rolling of aluminum alloy ingots is to provide billets for cold rolling, or to directly produce thick plates in hot rolled state.
6: the hot rolling process includes pass reduction, rolling temperature, rolling speed, and lubrication cooling.
After learn about the production process of aluminum sheet manufacturers, you must have a certain understanding of the production of high quality aluminum sheet plates. If you want to buy aluminum sheet, you must take 1100 aluminum sheet price and quality into consideration together.
