为进一步研究电弧炉底吹工艺对炼钢过程的影响,对电弧炉底吹工艺进行物理模拟及搅拌机理研究,以西宁特殊钢股份有限公司65 t电弧炉为基础展开相关试验,结果表明:在符合合理底吹气量的条件下,底吹砖寿命达到623炉,实现炉壳寿命与底吹砖寿命同步,底吹动力学条件较好,更有利于反应达到平衡,钢铁料消耗降低了5.836 kg/t,石灰消耗降低了10.827 kg/t,脱碳速率增加0.011%,电弧炉采用底吹工艺取得良好的冶金效果。
In order to further study the influence of EAF bottom blowing process on steelmaking process, the physical simulation and stirring mechanism of EAF bottom blowing process were studied. Relevant tests were carried out on the basis of 65t electric arc furnace in Xining Special Steel Co., Ltd. The results showed that: Under the condition of reasonable bottom blowing volume, the life of the bottom blown brick reaches 623 furnaces, the life of the furnace shell is synchronized with the life of the bottom blown brick, the kinetic conditions of the bottom blown blowing are better, the reaction is better balanced, the consumption of the steel material is reduced by 5.836 kg / t, the lime consumption is reduced by 10.827 kg / t, the decarburization rate is increased by 0.011%, and the metallurgical effect is obtained by the bottom blowing process in the electric arc furnace.
