The Process of Manufacturing Aluminum

2015-04-07

The aluminum and aluminum alloy by melting, casting, rolling preparation, flat rolling, heat treatment and finishing processes into the section of rectangular sheet or roll mill.

1. Aluminum and aluminum alloy plate and strip hot rolling, annealing state to state, all kinds of soft state and heat treatment state of supply.

2. Hot preparation including ingot quality inspection, heat, sawing, milling, aluminum and heating etc.

3. Semi continuous casting cooling speed is very high, difficult in the solid phase diffusion process, the ingot to form the chemical composition and structure, such as segregation, decrease of plasticity

4. The ingot surface segregation to the material, slag, scarring and defects such as cracks, should face milling (see the non-ferrous metal alloy ingot milling), which is an important factor to guarantee the good quality of finished surface.

5. Hot rolling, hot rolling aluminum alloy ingots is blank for cold rolled plate, hot rolled or direct production status.

 

6. Hot rolling system includes the pass reduction, rolling temperature, rolling speed, lubrication and coolin.
