随着连铸技术的发展,炼钢工艺日益强化,致使转炉炉衬的各部位蚀损极为不均,尤其是渣线部位,有时不得不停炉整体更换,造成很大浪费,同时,10炉以上高龄期炼钢操作,对衬炉也提出了更高的要求。为了有效维护炉衬,降低消耗,国内外相继开发了各种炉衬的喷补技术。喷补,尤其是在线半干热喷补是延长炉衬使用 With the development of continuous casting technology, the steelmaking process is increasingly strengthened, resulting in extremely uneven corrosion of various parts of the converter lining. In particular, slag line parts sometimes have to be shut down for overall replacement, resulting in a great waste. Meanwhile, over 10 furnaces High-age steelmaking operations, lining the furnace also made higher requirements. In order to effectively maintain the lining, reduce consumption, both at home and abroad have developed a variety of lining of the gunning technology. Spray, especially the online semi-dry spray is to extend the use of lining
