What are the basic steps for making 3mm aluminium sheet?
1. Aluminum sheet 3mm are supplied in hot rolled state, annealed state, various grades of soft state and various heat treatment states.
2. Preparation before aluminium sheet hot rolling mainly includes ingot quality inspection, soaking, sawing, milling, aluminum clad and heating.
3. During semi-continuous casting, the cooling rate is very high, the diffusion process in the solid phase is difficult, and the chemical composition and microstructure are easily formed inside the ingot, such as intracrystalline segregation, etc., which reduces the plasticity.
4. When there are defects such as segregated floats, slag inclusions, scars and cracks on the surface of the ingot, the face should be milled (see non-ferrous metal alloy ingot blank face milling), which is an important factor to ensure the good surface quality of the finished product
5. Hot rolling: Hot rolling of aluminum alloy ingots is to provide billets for cold rolling, or directly produce thick aluminum plates in hot rolled state.
6. The 3mm aluminium sheet sizes standard hot rolling process system includes the pass reduction rate, rolling temperature, rolling speed, lubrication and cooling, etc.
