Fe-Si droplets associated with graphite on blast furnace cokeStanislav S.Gornostayev1,Timo M.J.Fabritius1,Jouko J.Hrkki11. Laboratory of Process Metallurgy,University of Oulu,Oulu 90014,Finland摘 要:Fe-Si droplets on the surface of blast furnace (BF) coke from 25 to 50 cm at the tuyere level are mostly composed of Fe3Si, which has various shapes (round......
Reduction and Reoxidation of Silicon in Blast Furnace Hearth糜克勤摘 要:<正> This paper introduces both laboratory experi-ment and equilibrium calculations concerned withthe Si reduction and reoxidation.The results giveevidence that the Si transport in different directionsjust exists in the furnace hearth synchronistically,by which the desulphurization......

基于ANSYS的高炉炉墙温度场分析侯富昌1,王秀梅1,翁健1,林成城2,郑少波3(1.上海市上海大学机电工程与自动化学院2.宝山钢铁股份有限公司3.上海大学 材料科学与工程学院, 上海 200072)摘 要:通过建立高炉炉墙在多类边界条件下的计算模型,利用有限元分析软件ANSYS对高炉炉墙进行三维稳态温度场的分析计算.模拟了高炉炉墙,冷却板的温度分布状态,得出了炉渣渣皮厚度和炉墙热电偶温度之间的对应关系,为高炉操作提供了判断依据,确保高炉生产的稳定,顺行.关键词:高炉炉墙； ANSYS； 冷却板；......
method [10] and the technology has been used to produce crude bismuth by Hunan Shizhuyuan Nonferrous Metals Co., Ltd. Another traditional method of producing bismuth is reverberatory or blast furnace... furnace. According to this technology, concentrates are smelted in oxidation furnace, and then bismuth liquid molten slag flows into reduction furnace for reduction smelting. The method can get higher metal......
