本溪钢厂电渣钢的电耗一直比较高。1978年以来,由于提高了充填系数,改变渣量和渣比,电耗大大降低。1978年每炼一吨钢比国家定额降低62度,1979年上半年则降低89度,其措施是: 1.提高充填系量对50个电炉号的2Cr13钢铸造电极进行了不同充填系数的对比试验,试验情况和结果见表1。从表1可以看出,充填系数从0.237提高到0.318,生产率提高12％,每吨钢电耗降低60度。在此基础上,利用直径360毫米的30CrMnSiA和
Benxi Iron and Steel plant slag electricity consumption has been relatively high. Since 1978, the power consumption has been greatly reduced due to the increase of the filling factor and the change of slag quantity and slag ratio. 1978, a ton of steel refining per unit lower than the national standard 62 degrees, the first half of 1979 decreased 89 degrees, the measures are: 1. To increase the filling rate of 50 EAF 2Cr13 steel casting electrode was compared with different filling factor Test, test conditions and results in Table 1. As can be seen from Table 1, the filling factor increased from 0.237 to 0.318, the productivity increased by 12% and the electricity consumption per ton of steel decreased by 60 degrees. On this basis, the use of a diameter of 360 mm 30CrMnSiA and
