针对连铸机普遍存在铸造速度低的弱点,日本日立制钢所制成了一种在铸造速度上可与轧机生产能力相适应的新型高速连铸机——轮带式连铸机。这是一种由铸造轮与钢带构成的连铸机,一个直径3米的铜质铸造轮竖直地安装在连铸机的主体部位上,铸造轮外圆的一段弧面上紧压着一条由厚2.6毫米、宽280毫米的低碳钢钢带组成的无端头链带,这样自然地形成了连铸机的结晶器。 钢液由中间包垂直地注入结晶器,一面与结晶器同步旋转,一面受到冷却,在结晶器出口处形成了15毫米厚的凝固壳。铸坯
For continuous casting machine widespread casting speed is low, Japan’s Hitachi Steel made a casting speed can be compatible with the rolling mill production capacity of the new high-speed continuous casting machine - a belt-type caster. This is a continuous casting machine consisting of a casting wheel and a steel strip. A 3-meter-diameter copper casting wheel is mounted vertically on the main body of the continuous casting machine. A curved surface of the outer circumference of the casting wheel is pressed against An endless chain of 2.6mm thick, 280mm wide mild steel strip naturally forms the mold for the caster. Molten steel was poured vertically into the mold from the tundish and simultaneously with the mold while being cooled, a solidified shell of 15 mm thick was formed at the outlet of the mold. Slab
