The consumption of refractory materials per ton of steel has dropped significantly
Refractory material consumption per ton of steel decreased from 35kg~40kg in the early stage of reform and opening up to 25kg~30kg in the late 1990s, and then to 13kg~14kg in early 2021. Reduced to the international leading level of about 9kg. There are mainly the following 4 reasons: First, the iron and steel industry continues to adopt internationally advanced large-scale process technology and equipment, as well as modern and intelligent compact manufacturing process technology. The second is the simultaneous development of the refractory industry and the iron and steel industry; the variety and quality of refractory materials have reached the international advanced level, and the proportion of amorphous materials and the application of secondary resources have continued to increase. The third is the widespread use of advanced, high-efficiency and low-consumption technologies. For example, high-pass iron content iron ditch self-flowing castable and repair technology, ladle lining in...
