高炉风口小套供水系统的优化措施

Optimization of the Water Supply System for the Tuyere Small Sleeve of Blast Furnace

风口小套是高炉的关键设备,是热交换极为强烈的冷却元件,其在高温状态下不间断地受到液态渣铁和煤粉的冲刷,是高炉易损的设备。风口小套的破损与更换已成为高炉无计划休风增多的主要原因,针对如何优化风口小套供水条件来提高风口小套使用寿命,进行探讨。

As a critical equipment of blast furnace, tuyere small sleeve is a cooling component with strong heat exchange and an easily damaged BF element, suffering continuous flushing of liquid slag, hot metal and pulverized coal under high temperature. Damage and replacement of tuyere small sleeve have become the major reason for increasing nonscheduled shutdown of blast furnace. Therefore, this article discusses on optimization of the water supply condition for tuyere small sleeve so as to improve the service life of tuyere small sleeve.
