马钢股份公司重视高炉喷煤技术的应用,公司拥有的中型炼钢高炉的喷煤量不断上升。1995年马钢9座中型高炉喷煤量平均达到118kg/t 铁,比上年净增15kg/t 铁。今年1月份,中型高炉喷煤量达121kg/t 铁,保持中型高炉较好水平。该公司9座中型高炉,均建于50年代中后期。高炉喷煤设施老化,喷煤量多年徘徊在100kg/t 铁水平。去年初,公司选择了第二炼铁厂1号高炉为扩大喷煤量试点炉,完善了喷煤工艺和自动化控制系统,并推广应用流化
Maanshan Iron and Steel Company attached great importance to the application of blast furnace coal injection technology, the company owned medium-sized steelmaking blast furnace coal injection volume rising. In 1995, 9 medium-sized blast furnaces at Masteel hit an average of 118kg / t of coal, a net increase of 15kg / t of iron over the previous year. In January of this year, medium-sized blast furnace coal injection amounted to 121kg / t iron, to maintain a good level of medium-sized blast furnace. The company 9 medium-sized blast furnace, were built in the late 50’s. Blast furnace coal injection facilities aging, coal injection amount hovering at 100kg / t iron level for many years. At the beginning of last year, the Company chose No. 1 blast furnace of No. 2 Ironworks to expand the pilot coal stove for pulverized coal injection, perfected the coal injection process and automatic control system and promoted the application of fluidization
