1 概况西林钢铁公司二炼钢厂五台电弧炉采用的是无还原期冶炼(即单渣法冶炼),工艺流程为: 装料→熔化→氢化→出钢→包中合金化因合金全部在包中加入,要吸收大量热能,而我厂无任何炉外精炼设施,这部分热能全部由钢水物理热提供,因此出钢温度必须很高才能满足浇注要求,这个温度只能靠延长氧化期来获得,导致氧化期负担重、时间长、对电耗,炉龄、炉盖寿命等指标很不利。
1 Overview Xilin Iron and Steel Company two steelmaking plant Wutai using non-reduction smelting (ie, single slag smelting), the process is: loading → → → hydrogenation of steel tapping alloying alloy in the all due to The package to join, to absorb a lot of heat, and I plant without any furnace refining facilities, all of this part of the heat from the molten steel physical heat, so tapping temperature must be high to meet the casting requirements, the temperature can only be extended oxidation period Obtained, leading to a heavy burden of oxidation, a long time, the power consumption, furnace age, furnace life and other indicators is very unfavorable.
