我公司4号高炉于1994年12月投产。4号高炉热风炉的设计采取了一系列新技术,使其风温水平较其余3个高炉的热风炉有了较大的提高,取得了良好效果。此新型热风炉的设计采用了新型高效陶瓷燃烧器和冷风均匀配气装置两项专利技术;在结构设计上,采取了减薄耐火砖厚度, Our No. 4 blast furnace was put into operation in December 1994. No.4 blast furnace hot stove design adopted a series of new technologies to make the air temperature level than the other three blast furnace stove has been greatly improved, and achieved good results. The design of this new hot blast stove adopts two patented technologies: a new type of high efficiency ceramic burner and a uniform air distribution device of cold air. In the structural design, the thickness of the refractory bricks is reduced,
