Abstract: The wear - resistant lining of the original coal hopper plays an important role in protecting the funnel structure.This article through the analysis of the original coal wear-resisting lining damage mechanism, raw coal in the corrosion of strong acid liquid (such as sulfur, phosphorus composition) is steel corrosion and concrete "carbide" , the main factors when bunkering as a result of the impact of raw coal block lining deformation or loss of incentive, both together, causes the damage of funnel wear-resisting lining.Combined with practical engineering, puts forward new funnel wear-resisting lining - - microcrystalline ceramic metal composite plate, can effectively solve the shock and corrosion problem, wear-resisting lining damage caused to such engineering design and construction is of certain reference value.
