肩负着马钢公司三大炉(平炉、转炉、电炉)的炉材、补炉材质—煅烧冶金白云石的生产单位二炼钢焙烧车间,从1986年起,经过对白云石竖窑汽化冷却管革新改造,实践后表明; 冶金白云石焦消耗下降了39 kg/t钢。体积密度上升0.036 g/cm~(3)。杂质含量下降0.37％。全年节焦1170 t,节约软水8640 t和节省无缝 Magnesia shoulders the three furnace (open hearth, converter, electric furnace) furnace, make up the material - calcined metallurgy dolomite production unit two steel roasting workshop, from 1986 onwards, dolomite shaft kiln vaporization cooling pipe Innovative transformation, after practice shows that metallurgical dolomite coke consumption decreased by 39 kg / t steel. The bulk density increased by 0.036 g / cm ~ (3). Impurity content decreased by 0.37%. Year-round coke 1170 t, save soft water 8640 t and save seamless
