Since the increasing of the size of blast furnace and intensified steel making processes, such as high pressure roof, high blast temperature and integrated blowing process have been adopted, the campaign life of domestic large or medium-sized furnaces has encountered great challenges, which have greatly affected the safe production as well as the furnace life. Under the supervision of Professor Song Musen from Wuhan I&S group, our factory has developed 25 kinds of products in ten major series, such as micropore corundum refractory brick, compound brown corundum brick, corundum mullite brick, mould pressed micropore carbon brick, sintered micropore alumina carbon brick etc, and the matching mortar as well as other monolithic refractories. Meanwhile, our invited designers are specialized in collapsible design of refractories brick and integrated pre-assembling of the bricks for blast furnace parts including tuyere, taphole, slag notch, hearth and bottom etc on the adjustable platform with 20m*20 size.
Our blast furnace refractory series have been used in couples of furnaces such as 3200m3 blast furnace of Wuhan I&S group, 4350m3 blast furnace blast furnace o fBenxi I&S co., 2200m3 blast furnace of Baotou I&S co., 3200m3 blast furnace of Tianjin I&S co., 1260m3 blast furnace of Liuzhou I&S co.etc.
