Development of technology for lining steel-tapping hole of steel-teeming ladles with the use of nesting well blocks

Abstract

At OJSC «BSW – Management Company of Holding «BMC» were tested nesting well blocks for lining of steel-tapping hole of steel-teeming ladles ЭСПЦ-1, 2 with the working lining of piece goods. In the conditions of the enterprise during the full campaign of the working lining of steel ladles, intermediate repair of the slag belt, bottom blowing units and the steel-tapping holes is carried out. The steel-tapping hole is used to release steel from the steel ladle into the intermediate ladle. The purpose of the tests is to replace the «traditional» filling of the steel outlet with refractory concrete manually by molded nesting wellblocks due to the reduced risk of accident due to the lack of probability of metal «penetration» into the concrete, as well as reducing the volume and duration of repair of the working lining of steel ladles.
