Product Introduction

Description: Chrome corundum series refractory products use high-purity corundum and chromium oxide as main raw materials. Al2O3 and Cr2O3 react to form a continuous solid solution. Chrome corundum bricks form a continuous solid solution with high high temperature strength and low high temperature creep. At the same time, the product does not contain MgO, which avoids the cracking problem caused by the reaction with SiO2. Chrome corundum products have excellent resistance to V2O5,SO3 erosion ability, is the petroleum coke powder as fuel regenerator top is ideal refractory products.
