內(nèi)容簡(jiǎn)介Nakayama Steel Works stopped blast furnace operation in July 2002, and started the Nakayama Scrap Melting and Refining Process (hereafter called NSR) in October 2002. Since then, the converter has been changed into a compound furnace in which scrap melting and decarburization are repeated separate from the conventional decarburization furnace. The vessel life of the converter was gradually increased from 2500 to 3900 heats (+56%), but a further increase was not possible because of excessive brick wear in the bottom corner area*. To overcome this problem, a new method of installing bricks was devised for the round corner lining, which was different than the conventional horizontal method of laying bricks; this change resulted in good performance. This paper reports on the analysis, development, and performance of the new lining scheme.
