山西省闻喜县白水泥厂采用高炉熔融法生产白水泥。水淬融渣掺入适量的煅烧石膏与少量石灰,磨细制成的白色水硬性胶凝材料——高炉融渣白水泥。采用这种工艺生产白水泥,对原料中含铁量不限,因为高炉熔融法,用焦炭作燃料。这样可以把原料所含的氧化铁还原成金属铁,在烘干融渣过程中采用永磁滚筒除铁 Wenxi County, Shanxi Province, white cement plant using blast furnace production of white cement. Water quench slag mixed with the right amount of calcined gypsum and a small amount of lime, ground white cementitious white cementitious material - blast furnace slag white cement. The use of this technology to produce white cement, iron content of raw materials is not limited, because the furnace melting method, with coke as fuel. In this way, the iron oxide contained in the raw material can be reduced into metallic iron, and the permanent magnetic drum can be used to remove iron during the process of drying and melting slag
