根据实测数据,结合熔池工作制度、炉料性能、渣型等因索,从物理和化学的角度,探讨了炉体腐蚀的原因。认为高温熔体的机械冲刷是导致物理性腐蚀的根本原因;化学性腐蚀居次要地位。提出在渣线一带用冷却水套制造人工“炉壁结”以维护炉体的设想。 According to the measured data, combined with the molten pool working system, charging performance, slag type and other factors, from the physical and chemical point of view, discussed the furnace corrosion reasons. It is considered that the mechanical erosion of high temperature melt is the fundamental reason leading to physical corrosion. Chemical corrosion occupies a secondary position. Proposed in the slag line with the cooling water jacket to create artificial “furnace wall junction” to maintain the idea of ​​the furnace.
