摘　　要：介绍八钢一炼钢0#连铸机为提高产量而采取的一系列改进措施:通过扩大中间包上水口直径,优化二冷配水制度,合理分配各冷却段水的比例等,取得了较好的效果。0#连铸机平均拉速由2008年的3.04 m/min提高到2009年的3.21 m/min;产量大大提高,年产量由2008年的1005 179.926 t,提高到2009年的1040 853.075 t,提高了35 673.149 t,生产、铸坯质量比较稳定。A series of improvement measures for increasing output of the 0# continuous caster in Bayi Iron & Steel Co.,Ltd.,(Bayi Steel for short) were introduced.These measures include enlarging diameter of the tundish upper nozzle,optimizing the water distribution of the secondary cooling scheme,allocating the water proportion reasonably for each cooling section,etc.A better result was gained.The average casting speed was increased from 3.04 m/min in 2008 to 3.21 m/min in 2009.Production of the caster grew from 1 00...
