图拉黑色冶金科学生产协会在10吨平炉出钢过程中,采用气体一粉末混合剂对钢水进行了处理试验。混合剂是经喷咀装置,通过炉壁耐火材料砌体中的出钢槽喷入钢水的。在出钢的同时,将石墨电极插入炉子工作区一侧的出钢口区域使钢水氧化度稳定。在出钢时,往出钢槽内喷吹混合剂比往盛钢桶里加入同样混合剂有着更加有利的精炼过程动力学、热力学和工艺学条件。此时,反应相的接触面更加发展;没有氧化渣;反应区间 Tula Black Metallurgical Association of Science and Technology in 10 tons open hearth tapping process, the use of gas-powder mixture of molten steel treatment test. The mixture is spray nozzle device, through the furnace wall refractory brick trough poured into the molten steel. At the same time of tapping, the graphite electrode was inserted into the tapping area on the side of the work area of ​​the furnace to stabilize the degree of oxidation of molten steel. In tapping, the mixing of the mixture into the sump has more favorable kinetics, thermodynamics and technological conditions than adding the same mixture to the ladle. At this point, the reaction phase of the contact surface more development; no oxide residue; reaction zone
