遵循伟大领袖毛主席关于“独立自主,自力更生”以及“工业学大庆”的教导,经过几个月的坚苦奋战,二相工频有芯熔炼炉(以下简称电炉)自投产以来,大大改善了铸工车间熔炼工部的原有面貌,与原用冲天炉比较有显著优点: 1.经济指标好:单纯以用电价格和焦炭燃料比较,电炉费用较高。如果从原材料费用、辅助材料费用、电力或燃料费用及人工费用等五项指标通盘核算,一吨铸件成本要比冲天炉低很多。 Following the teachings of Chairman Mao on “independence, self-reliance” and “industrialization Daqing”, following the lead of Chairman Mao Zedong, after several months of hard work, the two-phase power-frequency core melting furnace (hereinafter referred to as EAF) has greatly improved the foundry workshop The original appearance of the Ministry of smelting, compared with the original cupola have significant advantages: 1. Economic indicators are good: simply based on electricity prices and coke fuel, electric furnace costs are higher. If from the raw material costs, auxiliary materials costs, electricity or fuel costs and labor costs of five indicators of a comprehensive accounting, a ton of casting costs much lower than the cupola.
