Abstract:

This paper studies a kind of new type castable used for end cover in centrifugal cast roll production.The castable is prepared with high\|quality flint clay as main raw material, mullite ore as matrix, and added alumina micro powder to produce mullite through the reaction of the introduced Al2O3 with SiO2 during use.The new type castable improves the thermal shock resistance, reduces the production cost and increases the service life.
