一、概述武钢二高炉有效容积1436立方米。第二代炉役从1965年8月30日开始至1981年8月8日停炉,历时约16年。其间1971年中修28天,更换渣口以上内衬及部分冷却设备;1978年对炉身支梁式水箱以上部分进行了一次喷补;1979年又从镶砖冷却壁上沿开始重新砌砖。一代炉令期间休风封炉次数较多,扣除休风封炉及检修时间,实际作业时间4907天,折合13年零5个多月。一代产铁量为762.78万吨,其中铸造铁162.94万吨,占总产量的21.36％。平均每立方米有效容积产铁5312吨,低于一高炉的6804吨。长期以来,武钢入炉原料(主要是烧结矿和球团矿)强度差,粉末多。特别是二高炉
First, an overview of WISCO second blast furnace effective volume of 1436 cubic meters. The second generation of furnace from August 30, 1965 until August 8, 1981 shutdown, which lasted about 16 years. During the repair in 1971, 28 days, replacing the slag above the liner and some cooling equipment; in 1978 on the shaft beam above the tank part of a gunning; in 1979 and from the mosaic wall along the wall began to re-brick . During the first generation of furnaces, there were more closures of windbreaks, excluding the closures and overhauls of the closed doors. The actual operation time was 4907 days, equivalent to 13 years and more than 5 months. A generation of iron production was 7.6278 million tons, of which 1.6294 million tons of cast iron, accounting for 21.36% of the total output. The average effective volume per cubic meter of iron 5312 tons, less than a blast furnace of 6804 tons. For a long time, WISCO into the furnace raw materials (mainly sinter and pellet) poor strength, powder and more. Especially the second blast furnace
