Abstract:

This paper introduced the investigation of the major repair of a large sintering plant and the sample analysis to discuss the cause of lining damage.The conclusions are as follows: the sintered mixture contacts with the furnace lining at high temperature and sticks to the furnace wall and forms hanging slag; the slag gets into the refractory lining through pores and cracks,the main component of iron oxide gradually diffuses and reacts with the refractories,which result in deterioration,erosion until cracking and falling off.
