测温装置在顶燃热风炉炉顶的应用

The Application of Temperature Measuring Equipment in Burning at the Top of the Hot Stove

高炉热风炉炉顶温度是重要的工艺参数。传统的测量方法是使用贵金属热电偶。随着顶温的不断提高,热电偶保护套管及偶丝极易损坏，导致生产成本的升高。将非接触式测温装置—红外测温仪用于热风炉炉顶温度的测量必须解决冷却和清扫两大难点，本文介绍的装置巧妙的解决了这两个问题而并未带来装置的复杂化和维护工作量的增加。

The temperature at the top of hot stove is a vital parameter in blast furnace processing. The traditional measuring method employs noble-metal thermocouple. When the temperature goes very high, the thermocouple protection tube and the couple wire are often damaged. It makes production cost increase. When employ untouched measure equipment-infrared pyrometer for the temperature at the top of hot stove, the cooling and cleaning must be taken into consideration. This article introduces a clever approach to solve the cooling and cleaning problems, without additional complicated equipment and maintenance.
