一、前言转炉风口操作异常繁重,而且在高温、粉尘、烟害、强大噪音和有炉渣烧伤危险的恶劣条件下工作。为了改善这种落后状态,我们于1973年着手研制气动捅风口机,1974年在连续吹炼炉上进行了捅风口机的工业试验,在该炉上连续两年使用的基础上,1976年开始研制转炉捅风口机,于1978年用于生产,1980年沈冶四台转炉全部用上了气动捅风口机,实现了机械化操作,节省人力50～70％,提高转炉生产能力10％。该机为单缸水平式,经过8年使用的实 I. INTRODUCTION The operation of the converter tuyere is extremely heavy, and it also works under the harsh conditions of high temperature, dust, smoke, strong noise and the danger of slag burns. In order to improve this kind of backwardness, we started to develop the pneumatic poke tuyere machine in 1973. In 1974, we carried out the industrial experiment on the poke tuyere machine in the continuous blowing furnace. Based on the continuous use of the stove for two years, starting from 1976 Development of converter poke tuyere machine, used for production in 1978, Shenye four furnace in 1980, all with pneumatic poking tuyere machine, to achieve a mechanized operation, saving manpower 50 ~ 70%, increase converter capacity of 10%. The machine is a single cylinder horizontal, after eight years of use of real
