January 1985 January 15 to 17, the Ministry of Metallurgical organized the national production, design, research, universities and other representatives of a total of 80 held in Wuhan WISCO No.4 blast furnace carbon water cooled thin bottom technical appraisal. WISCO fourth blast furnace effective volume of 2516 m ~ 3, is September 30, 1970 put into operation. The furnace in the country for the first time legislation lining brick water-cooled thin bottom (two-tier building brick 2.3 meters, two high-alumina brick 0.8 meters, a total thickness of 3.1 meters). In order to prevent floats, the upper carbon brick is provided with horizontal crossings. The bottom of the furnace is equipped with four radioisotope Co60 sources (up to 396 millicuries, a minimum of 131 millicuries, a total dose of 1022 milligrams
