electrification; electrify; charge (①The oxygen steelmaking process rapidly refines a charge of molten pig iron and ambient scrap into steel of a desired carbon and temperature using high purity oxygen. 氧气炼钢工艺使用高纯氧能快速将铁水和室温废钢铁炉料精炼成具有规定含碳量和温度的钢水。②In most North American steel plants, the hot metal leaves the blast furnaces containing 0.040 ~ 0.070% S, while the oxygen converters are charged with hot metal containing as little as 0.010 ~ 0.001% S, to conform to limits on steel composition set by caster operations and final product quality requirements. 在北美的大多数炼钢厂,高炉铁水的含硫量为 0.040% ~ 0.070% ;而为了使钢水成分能符合连铸机生产规定的成分范围和终产品的质量要求,兑人氧气转炉的铁水含硫量仅为 0.001% ~ 0.010%。) |
