Production Practice of Efficient Lining Brick Demolition for the Converter with Movable Bottom
For the problem of longer lining bricks demolition time and sereverly affected operation efficiency for the converter,the technological principle of the reaction between oxygen jet and Fe element in the reserved furnace slag to rapidly form the slag with high temperature and high FeO content is applied,the optimized control is performed on the process parameters of oxygen lance position,oxygen flowrate,oxygen blowing time,immersion erosion time during the furnace cleaning operation and furnace lining bricks demolition procedure,the result of rapidly,uniformly removing the splashed slag layer adhered to the lining bricks and improving the lining bricks demolition efficiency is achieved.Com-pared with the regular demolition method,the operation efficiency of efficient lining brick demolition method is in-creased by the values ranging from 22.22％to 23.33％,which provides a guarantee for the high-efficiency smelting production of the converter.
