无锡市第二钢铁厂1983年底委托马鞍山钢铁设计研究院帮助设计,采用纯高炉煤气为燃的斜料底式管坯加热炉,取代原设计的燃煤加热炉。设计中采用了充分保存和回收烟气余热的系统,六行程的翅片换热器预热空气;四行程管状换器预热煤气;炉体采用轻巧和绝热良好的砌砖结构,炉体架空;低温段采用轻质粘土砖作内衬,分二段供热并采用新型的MP平焰烧嘴和MF辐射烧嘴,用炉顶烧嘴取代了传统的侧墙布置烧嘴的形式;均热段布置三只MP平焰烧嘴,加热段布置二只MF辐射烧嘴。1985年2月投产一次成功,二年多来生产正常,各
At the end of 1983, Wuxi No.2 Iron & Steel Works commissioned Maanshan Iron & Steel Design and Research Institute to help design and adopt the oblique blanking type tube furnace heated by pure blast furnace gas to replace the original designed coal heating furnace. In the design, a system of fully saving and recovering waste heat of flue gas is adopted, and six-stroke fin heat exchanger preheats the air; the four-stroke tubular converter preheats the gas; the furnace body adopts a light brick structure and a good heat insulation structure; ; Low temperature section of lightweight clay brick lined with two sections of heating and the use of new MP flat flame burner and MF radiation burner, with a roof burner instead of the traditional layout of the side wall burner; both Hot segment layout of three MP flame burner, heating section layout of two MF radiation burner. February 1985 put into operation a success, more than two years to produce normal, all
