冶金部钢铁司组织专家于1986年10月23至24日在包头对包钢和攀钢研制的两种煤气调节型均热炉调焰烧嘴进行了技术鉴定。此项烧嘴的研制工作是根据1979年太原全国第二次均热炉会议的要求进行的。上述二厂的长坑均热炉都是以一次空气抽引陶土换热器的热空气,空气在烧嘴前的压力较低,因此为实现炉温均匀性而需研制的调焰烧嘴只能以煤气作为调节介质。包钢和包头钢铁设计院自1981年以来
Metallurgical Division Steel Division organized experts in October 23, 1986 to 24 in Baotou for Baotou Steel and Panzhihua Iron and Steel Research and Development of the two gas-controlled gas-fired stove tuyere burner technical appraisal. The development of this burner is based on the requirements of the second somatic furnace conference in Taiyuan in 1979. The long pit soaking furnaces of the above two plants all take the hot air of the clay heat exchanger by one air and the pressure of the air in front of the burner is low. Therefore, the burner for flame homogenization Gas can be used as a regulatory medium. Baotou Steel and Baotou Steel Design Institute since 1981
