梅山1号高炉于1970年投产,1985年9月大修。大修改造中把钟式炉顶改为串罐无料钟炉顶。根据国内外高炉布料技术的发展,针对无料钟布料存在的问题,对串罐(单罐)和并罐(双罐)两种形式进行论证比较并作了布料的模拟试验后认为,串罐无料钟炉顶在布料方面存在一定优点,径向矿焦比分布合理。同时在高炉大修中采用,炉顶容易布置,斜桥和矿槽改造工程量少,投资省。它的一些缺点在设计中作了充分的考虑。
Meishan blast furnace No. 1 put into operation in 1970, overhaul in September 1985. Overhaul of the transformation of the bell-style roof to bell-less bell-free top. According to the development of blast furnace fabric technology at home and abroad, aiming at the problems of material without bell, the two forms of string cans (single can) and cans (double cans) are compared and the simulation test of fabric is made. There is no advantage of material bell top in fabric, and the distribution of radial mineral coke ration is reasonable. At the same time used in blast furnace overhaul, easy to arrange roof, inclined bridge and mine reconstruction project less investment in the province. Some of its shortcomings in the design made full consideration.
