高炉冶炼的合适造渣制度,必须强调稳定渣冶炼,无论是采用低二元碱度或是高二二元碱度的炉渣,都应当把炉渣成份选择在稳定渣区域内,只有稳定渣冶炼,才能保证高炉顺行,好操作,才能优质、高产、低耗、长寿。最合适的高炉渣成份范围是CaO-SiO_2—MgO—Al_2O_3四元系炉渣相图中的黄长石,镁蔷薇辉石和钙镁橄榄石的三种稳定渣区域,通常是在前两个区域。我国的大、中型高炉,原燃料成份波动不大,吨铁硫负荷不高(一般在10公斤以
Blast furnace smelting suitable slagging system, we must emphasize the stability of slag smelting, whether it is using low binary basicity or high binary basicity of the slag should be selected slag composition in the area of stable slag, only stable slag smelting, In order to ensure smooth blast furnace, good operation, to high quality, high yield, low consumption, long life. The most suitable range of blast furnace slag composition is the three stable slag zones of the feldspar, the magnesium rosette, and the calcium-forsterite in the phase diagram of the CaO-SiO 2 -MgO-Al 2 O 3 quaternary slag, usually in the first two regions. China’s large and medium-sized blast furnace, the original composition of the fuel fluctuations, iron and sulfur tons of load is not high (usually 10 kg
