Abschnitt 2.5 - 2.5 Further casting processes
Cast rolling for the production of magnesium sheets and magnesium strips, for example with a strip thickness of approx. 5 mm, is a rather rarely used process. A casting-rolling system usually consists of a melting furnace, a molten metal outlet forming a gap (tip) as well as a rolling and cooling unit.
The emerging liquid molten metal, which has a temperature of approx. 700 °C, is suddenly "quenched" to approx. 250 °C by means of two cooled rollers. Protective gas is supplied at the point of exit of the molten metal to protect the area against atmospheric oxygen. When handling the molten metal, the measures described in clause 2.2 shall be observed.
