RH kiln Gunning Mix

RH kiln Gunning Mix

According to the construction characteristics of the spray material, combined with the problem that the inner wall of the RH impregnation pipe is washed by high temperature molten steel and the outer wall is corroded by molten slag, the high quality magnesite and magnesia-chrome sand are selected as the main raw materials, and the unique composite binder and admixture are added. This series of products has the characteristics of high adhesion strength, low rebound rate, easy sintering, erosion resistance, erosion resistance, etc. It is the ideal material for spray repair maintenance of RH furnace impregnation pipe and prolonging the service life of RH furnace。
