一、前言武钢4号高炉是1970年5月份边设计边施工,于同年9月30日建成投产的,容积为2516米~3,是当时国内最大的高炉。受客观条件的限制,其主要设备是由1513米~3高炉配套设备改制的,如利用2台4250米~3/分风机并联送风、料车卷扬机为22.5吨、料车容积为15米~3、料钟平衡杆装置进行局部加固等。因此,对2516米~3高炉而言,无论是风机、上料和装料设备能力与日产生铁5000吨的要求均不相通应。特别是1977年10月从国
I. Introduction WISCO No.4 blast furnace was designed and constructed in May 1970 and completed and put into production on September 30 of the same year with a volume of 2,516m ~ 3, which was the largest blast furnace in China at that time. Subject to the objective conditions, the main equipment is from 1513 m ~ 3 blast furnace supporting equipment restructuring, such as the use of 2 units 4250 m ~ 3 / sub-fan in parallel air, car winch was 22.5 tons, expected car volume of 15 m ~ 3, material bell balance bar device for local reinforcement. Therefore, 2516 m ~ 3 blast furnace, both the fan, feeding and loading capacity of 5,000 tons of pig iron and day production requirements are not the same. Especially in October 1977 from the country
