补充资料:冶金长度
冶金长度
metallurgical length
yejin ehangdu冶金长度(metallurgieal length)指连续铸钢过程中由结晶器内钢液面至液芯全部消失之终点处的距离,也称液芯长度。冶金长度用L表示,T为铸坯全部凝固时间,v。为拉坯速度,则其表达式为 L一Tv。冶金长度是设计连铸机的重要工艺参数。由于钢水温度、冷却强度等的变化。铸坯的全凝时间也有变化。故冶金长度不是固定不变的。为了在设计中准确表示铸机规格及其生产能力,引入了铸机长度的概念,其定义式为: 铸机长度~铸坯最大冶金长度x(1+富余量)富余量的确定与铸机预留发展潜力及辊列设计有关,一般在。一。.15之间。冶金长度只是一个与工艺条件有关并在一定范围内变化的冶金量。而铸机长度则表示能满足冶金长度并有明确数字的机械设备参数。 (熊毅刚)
