建立了套筒式高炉氧煤枪管壁温度的数学模型，得到有关温度的计算值，并用带有多点热电偶的高炉套筒式氧煤枪测量了带旋流头和不带旋流头的套筒式氧煤枪外管的温度及枪头内部其他部位的温度分布。套筒式氧煤枪外管壁平均温度不超过６００℃，与数学模型计算结果基本吻合。
The mathematical model of the wall temperature of the sleeve coal-fired blast furnace was set up, and the calculated temperature was obtained. The blast furnace oxygen-guns with multi-point thermocouple Of the sleeve Oxygen gun outer tube temperature and other parts of the temperature inside the tip of the distribution. The average temperature of the outer wall of the sleeve type oxygen coal gun does not exceed 600 ° C, which is in good agreement with the mathematical model.
