前言高炉冶炼,热风的供应是其一个不可缺少的要素。热风是通过风口进入炉中的,风口寿命的长短对高炉送风制度能否正常关系甚大,而送风制度的正常与否又关系到炉况的顺行与设备的安全运转,为了保证高炉的作业顺行,促进优质高产低消耗,减少设备事故,就必须尽可能的减少送风制度的波动。因此,延长风口的寿命便成为高炉生产中的一个主要课题。我厂在1970年以前,由于风口烧损严 Foreword Blast furnace smelting, hot air supply is an indispensable element. Hot air is through the tuyere into the furnace, the length of the tuyere blast blast furnace air supply system is normal or not, and the normal or not the air supply system is also related to the furnace conditions along with the safe operation of equipment in order to ensure the blast furnace Work in line to promote high-quality high-yield low-consumption, reduce equipment accidents, it is necessary to minimize fluctuations in the air supply system. Therefore, to extend the life of tuyere has become a major issue in blast furnace production. I plant before 1970, due to the tuyere burned strictly
