辽宁省地方(不包括鞍、本钢)轧钢企业,自1979年以来按照加热炉“五个必须”,即炉底水管必须包扎;炉子必须绝热保温;炉体必须严密;余热必须利用;必须有计量监测装置的要求。普遍开展了以节能为中心的技术改造,取得了较好的效果。 1982年全省地方轧钢吨坯材油耗为67.83公斤,比1979年的97公斤,少耗29.17公斤,下降30％;轧钢煤耗实物量平均为159.2公斤,比1979年的234公斤,少耗74.8公斤,下降32％。由于轧钢加热炉提高了等级,仅油、煤耗这一
The steel-making enterprises in Liaoning Province (excluding the saddle and Benxi Iron and Steel Works) have been “five musts” of furnaces since 1979, that is, the furnace bottom pipes must be bandaged; the furnaces must be insulated and insulated; the furnaces must be tight; the waste heat must be used; Metering monitoring device requirements. In general, energy-saving technological transformation has been carried out and good results have been achieved. In 1982, the provincial fuel consumption per ton of rolled steel was 67.83 kilograms, 97.7 kilograms less than that of 1979 and 29.17 kilograms less, a decrease of 30%. The average coal consumption per ton of rolling steel was 159.2 kilograms, 234 kilograms less than 1979 and 74.8 kilograms less , Down 32%. As the rolling furnace to improve the level, only oil, coal consumption of this one
