在目前的原燃料条件下，为保证马钢2500m3高炉炉渣具有良好的流动性和较高的脱硫能力，炉渣的CaO／SiO2应控制在1．05至1．15之间，炉渣温度不低于1450℃．
Under the current raw fuel conditions, in order to ensure that Magang’s 2500m3 blast furnace slag has good fluidity and high desulfurization capacity, the CaO / SiO2 of the slag should be controlled between 1.05 and 1.15 and the slag temperature should not be lower than 1450 ° C.
