唐钢与东北工学院共同协作于1987年在唐钢2号高炉进行从渣口向炉缸喷压缩空气的试验.第一阶段试验期为1987年8月16～26日,基准期为同年7月26日至8月5日;第二阶段试验期为1987年11月23日至12月3日,基准期则为同年12月4～13日。2号高炉容积100m~3,炉缸直径3m,6个风口,1个渣口(在3号风口下面)与铁口成120°夹角。喷枪是将原有堵渣机改造成中心输入压缩空气的吹风堵渣机。输送管道直径为 Tangshan Iron and Steel and Northeast Institute of Technology to work together in 1987 in the No. 2 blast furnace in Tangshan Iron and Steel Company to carry out compressed air from the slag mouth to the hearth test.The first phase of the test period August 16, 1987 26, the base period of 7 Month 26 to August 5; the second phase of the trial period is November 23, 1987 to December 3, the reference period is December 4 to 13 the same year. 2 blast furnace volume 100m ~ 3, hearth diameter 3m, 6 tuyeres, a slag hole (in the No. 3 tuyere below) and the iron mouth into a 120 ° angle. Spray gun is the original plugging machine into the center of compressed air into the air plugging machine. Pipe diameter is
