Casting of Clad Strip of Al-SiCp, Magnesium Alloy Hard-Brittle Light Material by a Twin Roll Caster

Article Preview

Abstract:

Casting of clad strip consisting of Al-30vol%SiCp and 1070 aluminum alloy, and clad strip consisting of AM60 magnesium alloy and AZ121 magnesium alloy was carried out in an oxidizing atmosphere by two types of twin roll casters. One was the vertical type twin roll caster equipped with a scraper and the other was the melt drag type vertical type twin roll caster, both operating at a speed of 30 m/min and a roll load of 0.2 kN/mm. The clad strip of the aluminum alloys could be cast by both twin roll casters. The clad strip of the magnesium alloys could be cast only by the vertical caster equipped with a scraper. The clad strips were bonded strongly at the interface in spite of the high roll speed and the low roll load.
