Practice of Gasifier Hearth Grouting Protection in Bayi Steel
The charging column height of the gasifier of eurosmelter is 8.6 m,the design diameter of the hearth is 9380 mm,and a total of 28 oxygen tuyeres are set,using pure oxygen smelting.The gasifier was opened in June,2015,and gas leakage oc-curred in the iron mouth area of the gasifier to varying degrees,resulting in iron splashing and difficult maintenance and opera-tion in front of the gasifier.In recent years,the hot surface carbon material grouting maintenance,the cold surface gap blocking filling method,and the hot surface lining technology have been carried out to maintain the hearth,which has effectively solved the problem of gas leakage in the iron mouth area.
