攀钢120吨转炉的扩容设计,需要炉体在冶炼过程中各部位温度分布数据,作为各部位结构强度验算的计算依据。为此,在攀钢提钒炼钢厂1~#转炉上,分别测定了托圈和炉壳外表面各测点的温度。根据炉体各部位的具体情况,确定采用焊接开路热电偶接触式和低温红外测温仪非接触式测定相结合的方法进行测定。对用红外测 Panzhihua Iron and Steel 120 tons of converter capacity expansion design, the furnace body in the smelting process needs temperature distribution of various parts of the data, as part of the calculation of the structural strength of the calculation basis. To this end, in Panzhihua Iron and Steel Company 1 ~ # vanadium converter, were measured on the outer surface of the ring and the furnace shell of the measuring point temperature. According to the specific conditions of various parts of the furnace to determine the use of open-circuit thermocouple welding and low temperature infrared thermometer non-contact measurement method for the determination. To use infrared measurement
