制作铝镁锰板离不开哪些步骤？

1、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镁锰板。
1. Aluminum and aluminium alloy sheets and strips are supplied in hot-rolled, annealed, soft and heat-treated states.
2、热轧前预备 重要包括铸锭质量检查、均热、锯切、铣面、包铝和加热等。
2. The preparation before hot rolling mainly includes ingot quality inspection, soaking, sawing, milling, aluminium cladding and heating.
3、半延续铸造时冷却速度很高，固相中的扩散过程困难，铸锭内部易形成化学成分和组织不均，如晶内偏析等，使塑性降低

3. High cooling rate in semi-continuous casting, diffusive process in solid phase is difficult, chemical composition and microstructure heterogeneity are easy to form in ingot, such as intragranular segregation, which reduces plasticity.

4、铸锭外观有偏析浮出物、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)关键词排名，这是保证制品优秀外观质量的一个紧张因素
4. When the surface of ingot is defective such as segregated float, slag inclusion, scarring and crack, it should be milled (see milling surface of non-ferrous alloy ingot), which is an important factor to ensure good surface quality of finished product.
5、热轧：铝合金铸锭的热轧是为冷轧提供坯料，或直接生产热轧状况的厚板。
5. Hot rolling: Hot rolling of aluminum alloy ingots is to provide blanks for cold rolling, or directly produce hot rolled thick plates.
6、热轧工艺制度包括道次压下率、轧制温度、轧制速度以及润滑冷却等
6. Hot rolling process system includes pass reduction rate, rolling temperature, rolling speed and lubrication cooling.
