前言化铁炉造渣制度直接影响着冶炼的各项技术经济指标。但多年来人们对其研究不多,碱性化铁炉习惯于采用石灰加萤石造高碱度渣,炉内配加萤石量有的可达30～40公斤/吨,由于萤石价格昴贵(每吨一百多元),对炉衬侵蚀厉害,大量使用势必提高冶炼成本,且造成环境严重污染。因此,化铁炉的造渣制度必须进行改革。自78年以来,在唐钢一炼35吨碱性(冷风)化铁炉上开始了多种造渣制度的生产实验。以白云石代替部分萤石,大幅
The preamble furnace slagging system directly affects the smelting of various technical and economic indicators. However, people have not much research on it for many years. Alkaline iron furnace is accustomed to using lime and fluorite to make high alkalinity slag. The amount of fluorite in the furnace is up to 30-40 kg / ton, Expensive (more than one hundred yuan per ton), powerful erosion of the lining, heavy use will inevitably raise the cost of smelting, and cause serious environmental pollution. Therefore, the slagging furnace system must be reformed. Since 78 years, the production experiment of various slagging systems began at Tanggang Iron and Steel 35 tons of alkaline (cold) boilers. Dolomite instead of some fluorite, substantial
