安阳钢铁集团公司研究出的高炉烟煤无烟煤混喷新技术在安钢炼铁厂5座300m~3级高炉上应用成功,最近在河南郑州通过了省科委组织的专家鉴定。过去,安钢炼铁厂高炉喷煤采用传统的无烟煤进行喷吹,当煤比超过90kg/t时,就会使炉内未燃煤粉增多,造成煤焦置换比下降。采用该技术后,烟煤喷 Anyang Iron and Steel Group Corporation developed a new technology of blast furnace bituminous coal mixed with smoke in Anyang Iron and Steel Works 5 300m ~ 3 blast furnace applied successfully, recently in Zhengzhou, Henan Province passed the identification of experts organized by the Provincial Science and Technology Commission. In the past, Anyang Iron and Steel Blast Furnace coal injection using traditional anthracite injection, when the coal ratio exceeds 90kg / t, it will make the furnace unburned coal increased, resulting in coal to coal replacement ratio decreased. After using this technology, bituminous coal spray
