重庆钢铁公司多用钢锭直接轧材,其锭模系列及钢锭形状对成材率影响很大。鉴于原有锭模系列不尽合理,致使板材产品不能形成合理系列,轧定尺板成材率低;同时,随着浇注工艺的发展和轧钢工艺的改进也必须对原有钢锭形状进行修改,以使成材率得到进一步提高。根据重钢炼钢、轧钢现有生产条件拟定了扁锭系列化方案,从1983年以来,设计了三种锭模五种 Chongqing Iron and Steel Company multi-purpose steel ingot direct rolling, the ingot mold series and ingot shape of the finished product rate. In view of the original series of ingot mold is not reasonable, resulting in a reasonable series of plate products can not be formed, Rolled Ruler plate forming rate is low; the same time, with the development of pouring process and the improvement of the rolling process must be the original shape of the ingot to be modified to So that the yield rate to be further improved. According to the existing production conditions of heavy steelmaking and rolling, a series of plans for the production of ingots have been formulated. Since 1983, three kinds of ingots have been designed
