铝和铝合金板带材以热轧状况、退火状况、各种级别的软态和各种热处理状况供给铝板。
Aluminum and aluminium alloy sheets and strips are supplied by hot rolling, annealing, various grades of soft and various heat treatment conditions.
热轧前准备 首要包含铸锭质量检查、均热、锯切、铣面、包铝和加热等。
The preparation before hot rolling mainly includes quality inspection of ingot, soaking, sawing, milling, aluminium cladding and heating, etc.
半连续铸造时冷却速度很高，固相中的分散进程困难，铸锭内部易构成化学成分和组织不均，如晶内偏析等，使塑性降低。
In semi-continuous casting, the cooling rate is very high, the dispersion process in solid phase is difficult, and the chemical composition and structure of ingot are uneven, such as intragranular segregation, which reduces the plasticity.

铸锭表面有偏析浮出物、夹渣、结疤和裂纹等缺陷时，应进行铣面(见有色金属合金锭坯铣面)，这是保证制品良好表面质量的一个重要因素
When there are defects such as segregation float, slag inclusion, scarring and crack on the surface of ingot, milling surface (see milling surface of non-ferrous metal alloy ingot) should be carried out, which is an important factor to ensure good surface quality of products.
热轧：铝合金铸锭的热轧是为冷轧供给坯料，或直接生产热轧状况的厚板。
Hot rolling: Hot rolling of aluminium alloy ingot is to supply billet for cold rolling or directly produce thick plate in hot rolling condition.
热轧工艺制度包含道次压下率、轧制温度、轧制速度以及润滑冷却等
Hot rolling process includes pass reduction rate, rolling temperature, rolling speed, lubrication and cooling, etc.
