摘要: 针对重钢顶吹转炉 (铁水装入量 85t)改造成顶底复吹转炉钢液和渣液深度及炉子结构、尺寸和改造设计的特点 ,设计制作了复吹转炉冷态模拟模型 ,实验研究了流股对熔池冲击作用效果 ,转炉不同炉役期熔池的搅拌混匀特性 ,熔体对炉壁的冲刷作用。实验结果得出重钢转炉在整个役期内合理的底吹供气强度为0.06~0.11 m3/min·t;顶底复吹时 ,基本枪位下操作对熔池搅拌混匀时间最短

Abstract: According to characteristics of the depth of metal and slag, the furnace structure and size, and the revamping design for an top-blown converter (charging metal 85 t) modified to a top and bottom combined blown converter, a cold simulation model for top and bottom combined converter has been designed and established to test and study the effect of flow impinging on converter bath, the mixing characteristics of bath in different melting period and the scouring action of melt on furnace wall, the test results showed that the reasonable bottom blown strength was 0.06~0.11 m3/min▪t for the converter at Chongqing Steel; and in top and bottom blown, the bath mixing time was lowest by operation at basic lance location.
