The basic reason for the erosion of <span style=\"color:red\">hearth</span> bottom is its direct contact with hot metal. According to the theory of heat transfer, models of BF <span style=\"color:red\">hearth</span> bottom are built based on the actual examples using software and VC language, and the calculated results are in good agreement with the data of BF dissection after blowing out. The temperature distribution and the capability of the resistance to erosion for different structures of <span style=\"color:red\">hearth</span> bottom are analyzed, especially the two prevalent kinds of <span style=\"color:red\">hearth</span> bottom arrangements called “the method of heat transfer” for allcarbon brick bottom and “the method of heat isolation” for ceramic synthetic <span style=\"color:red\">hearth</span> bottom. Features of the two kinds of <span style=\"color:red\">hearth</span> bottoms are analyzed. Also the different ways of protecting the <span style=\"color:red\">hearth</span> bottom are clarified, according to some actual examples. After that, the same essence of prolonging life, and the fact that the existence of a “protective skull” with low thermal conductivity between the hot metal and brick layers is of utmost importance are shown.","authors":[{"authorName":"ZHAO Hongbo","id":"f9ef04a8-14a6-4215-8deb-4d304c3e67b0","originalAuthorName":"ZHAO Hongbo"},{"authorName":"CHENG

The concept of research and development was integrated in the construction of BF (blast furnace) No5  at WISCO (Wuhan Iron and Steel Corporation), and in October, 1991, the BF No5 was blown in. The blast furnace has worked smoothly for more than 15 years without any medium repair even guniting. It is expected that the campaign life of BF No5 would be longer than 16 years with a production over 11 000 t per unit inner volume (m3). A new blast furnace with an inner volume of 3 400 m3 is under construction, and is designed with a campaign life of 20 years without any medium repair. The campaign life of blast furnaces in China has been extended in recent years.","authors":[{"authorName":"ZHANG Shourong","id":"b9e3b69f-6e5e-4ee8-96c1-4bdec8952207","originalAuthorName":"ZHANG Shourong"}],"categoryName":"|","doi":"","fpage":"1","id":"2422d6c0-83ef-4812-8279-c218ad083175","issue":"6","journal":{"abbrevTitle":"GTYJXBYWB","coverImgSrc":"journal/img/cover/GTYJXBEN.jpg","id":"1","issnPpub":"1006-706X","publisherId":"GTYJXBYWB","title":"钢铁研究学报(英文版)"},"keywords":[{"id":"74e98005-8923-425c-be32-acaee8452fd9","keyword":"blast furnace;campaign life;erosion","originalKeyword":"blast furnace;campaign life;erosion"}],"language":"en","publisherId":"1006-706X_2006_6_10","title":"Practice for Extending Blast Furnace Campaign Life at Wuhan Iron and Steel Corporation","volume":"13","year":"2006"},{"abstractinfo":"To fully utilize Panzhihua titanium resources, a new process was proposed.
