包钢现有三座高炉(2×1513米~3和1×1800米~(?)),按年产铁290万吨计,大约需喷吹38万吨煤粉。远景规划年产600～1000万吨铁,则需喷吹煤粉80～130万吨。为了获得最佳喷煤方案,首先必须选择合理的煤源基地及适宜的煤种。内蒙现已探明的煤矿资源极为丰富,贮量居全国第二位。本着就近择优、近期与远期相结合的原则,经多方面比较,选定了内蒙的杨格楞矿和白狐沟矿的烟煤,以及宁夏石炭井卫东矿的无烟煤作为包钢喷吹用煤并对其理化性能进行了测定和分析,从中找出适合的最佳煤种及最佳配煤方案。
There are three blast furnaces in Baotou Steel (2 × 1513m ~ 3 and 1 × 1800m ~ (?)), With an annual output of 2.9 million tons of iron and about 380,000 tons of pulverized coal injected. Long-term planning with an annual output of 600 to 10 million tons of iron, you need to blow 80 to 1.3 million tons of pulverized coal. In order to obtain the best coal injection plan, we must first select a reasonable coal source base and the appropriate coal. Inner Mongolia is now very rich in proven coal resources, storage ranks second in the country. Based on the principles of near merit and recent and long-term integration, the anthracite of Yanggelunchuan and Baoxuogou in Inner Mongolia and the anthracite of Weidong mine in Ningxia are selected as the steel for blast furnace by many aspects Coal and physical and chemical properties of its determination and analysis, from which to find the best coal and the best coal blending program.
