The basic steps to production <strong>aluminum metal sheets</strong>：<br>
1, aluminum and
aluminum alloy plate sheet in hot rolling, annealing state and various levels of the soft mode and supply of various heat treatment states.<br>
2, the hot rolling aluminum metal sheets preparation: including ingot quality inspection, soaking, sawing, milling, aluminum and heating etc.<br>
3, semicontinuous casting cooling rate is very high, in the solid phase diffusion process is difficult, ingot casting internal easy to form chemical composition and organization, such as coring, lower the plastic.<br>
4, the ingot surface segregation, surface, slag, scab and cracks and other defects, milling surface should be carried out, which is an important factor to ensure <strong>hot/cold rolled
aluminium sheet </strong>have a good surface quality .<br>
5. Hot rolling: the hot rolling of
aluminium alloy ingot is the <strong>hot rolled
aluminum plate</strong> for cold rolling or directly producing hot rolling.<br>
6, the system of hot rolling process including the time of pressing rate, rolling temperature, rolling speed, and lubrication cooling, etc。</p>
