Effect of Roll Material on Strip Solidification between the Rolls of a Vertical-Type High-Speed Twin-Roll Caster

Tool steel for hot working is usually used the rolls of conventional twin-roll casters aluminum alloys. In a vertical high-speed caster, copper are to rapidly solidify alloys and increase casting speed, since thermal conductivity higher than that tool steel. However, degree superiority over not clear. present study, effect roll material on strip solidification between caster was investigated by inserting thermocouple in during casting. The Al-4.8%Mg alloy used, it does stick absence parting material. Both mild were used. cooling rate, supercooling liquidus temperature, temperature cast using superior those rolls. better terms achieving casting, rapid strip, high productivity.
