对45 t电炉终点碳控制技术进行研究,优化了冶炼工艺及用氧制度,改进了泡沫渣工艺.电炉氧化末期钢水碳的合格率得到较大提高,减少了脱氧材料加入量,在一定程度上降低了LF座包钢水中的氧含量.通过优化泡沫渣工艺,电炉炉盖结冷钢现象已基本杜绝,炉子水冷件漏水现象大幅度减少,缩短了热停时间.
The end carbon control technology of 45 t electric furnace was studied, the smelting process and the oxygen system were optimized, and the foaming slag process was improved. The pass rate of the molten steel carbon in the late stage of the electric furnace oxidation was greatly increased, which reduced the amount of deoxidation material to a certain extent Reducing the oxygen content in the LF ladle molten steel.By optimizing the foam slag process, the phenomenon of cold-formed steel in the electric furnace lid has been basically eliminated, the leaking phenomenon in the furnace water-cooled part has been greatly reduced, and the heat stop time has been shortened.
