我厂83.5米~3高炉于1958年10月投产,其设计与国内82～84米~3高炉相类似。通过几年的生产实践,我们认为,原设计不尽合理,其不合理之处主要表现为下列三方面: 1.高炉内衬全部为粘土砖砌筑,成本高昂。小高炉面积与体积之比较大高炉为大,冶炼强度一般较大高炉为高,加之一般地方企业采用的粘土砖质量较差,砌砖质量技术不高,因而下部易被侵蚀,寿命较短。湖南地区的小型高炉寿命一般在一年半至两年之间。我厂83.5米~3高炉的第一代和第二代寿命均为两年。因此我们认为有必要采用新型的质高价廉的耐火材料,以延长高炉寿命。我们的意见以采用炭素捣固为宜。
83.5 m ~ 3 blast furnace in our factory was put into operation in October 1958. Its design is similar to that of 82 ~ 84 m ~ 3 blast furnace in China. Through several years of production practice, we believe that the original design is not reasonable, its unreasonable place mainly in the following three aspects: 1. Blast furnace lined with all clay brick masonry, high cost. Small blast furnace area and volume ratio of large blast furnace, smelting strength is generally high blast furnace is high, combined with the general local enterprises using poor quality clay bricks, masonry quality technology is not high, so the lower susceptible to erosion, shorter life expectancy. Small blast furnace in Hunan Province is generally a year and a half to two years. I plant 83.5 m ~ 3 blast furnace of the first and second generation of life are two years. Therefore, we think it is necessary to adopt a new type of high quality and cheap refractory materials to prolong the life of the blast furnace. Our opinion to use carbon tamping is appropriate.
