在高炉风口的筒体前端边缘,有冷却风口用的总冷却室和作区段冷却用的仔冷却室。仔冷却室与装有给水温度计的排水管相连,在给、排水管的任何一边或两边装上流量计。用给、排水温度计及流量计所指示的值,再根据通过仔冷却室的测温水的温度,计算出仔风口前端部分取得的热量,就可知道铁水的硅含量及铁水温度变化状况。
Blast furnace tuyere at the front edge of the cylinder, the cooling air outlet with the total cooling chamber and section cooling for Aberdeen cooling chamber. The cooling chamber is connected to a drain pipe containing a feed thermometer and a flow meter is installed on either side or both sides of the feed and drain pipe. Using the values given to the discharge thermometer and the flow meter, and then calculating the heat gain from the front end of the tuyere based on the temperature of the temperature measurement water passing through the cooling chamber, the silicon content of the molten iron and the change of the temperature of the molten iron can be known.
