发明名称 Method of continuous casting thin steel strip
摘要 In a twin roll continuous caster, the formation of skulls in the triple point region, the heat flux between the molten metal in the casting pool and the surfaces of the casting rolls, and consequently the casting speed and strip thickness, are controlled by controlling the level of carbon dioxide to at least 20% present in the casting area atmosphere above the casting pool supported on the casting surfaces of counter-rotating casting rolls. The carbon dioxide level in casting area may be more than 40%, 50%, 60%, 75% or 90%. The gas mixture in the casting area above the casting pool may be more than 0.05% free oxygen.
