The Roll Casting -Hot Rolling for Magnesium Alloy Sheet

摘要

We have developed a low-cost method for commercially producing magnesium sheet. The equipment consists of a system of magnesium melting and metal liquid supply, a twin rolling caster, a hot roller, a cutter etc. Commercial quality AZ31B, MB8 and MB26 sheet of 600 mm wide have been successfully produced. We studied the forming processing of roll casting and hot rolling, properties and microstructure of sheets. The results show that the key factors are the stability of the molten metal temperature, the pressure head in the tundish, the thermal insulation capability of the mouth, roll casting speed and hot rolling parameters.
