Effect of Some Factors on Fabrication of Clad Strip by a Roll Caster
A vertical tandem positioned twin roll caster and an unequal diameter twin roll caster were used in this study. Factors which affected the connecting of the strips in the fabrication using a roll caster were investigated. They were influences of oxide film, roll-load (separating force) and temperature of a strip. In the clad-strip casting by the roll caster, the connecting could be operated before the oxide film became firmly. Mn was useful element to prevent the oxidation. The roll-load could break the oxide film existed on the strip surface. Prevention of the occurrence of the oxide film was important to make strip connecting condition firm. In the casting of the clad strip using an unequal diameter twin roll caster, strips did not contact to the atomosphere before connecting.
