Details Introduction
Widely used as lining materials for cracking and conversion furnaces in petrochemical and fertilizer industries, gasification furnaces for residual oil, coal gasification furnaces, carbon black reaction furnaces, pulp waste liquid gasification furnaces, and other industrial furnaces.
Product introduction: Corundum bricks are refractory products made primarily from alumina, with corundum as the main crystalline phase. Corundum bricks possess excellent erosion resistance, wear resistance, high-temperature strength, load softening temperature, and creep, among other thermodynamic properties. The high bulk density and good thermodynamic properties of corundum bricks enable them to withstand thermal, chemical, and structural damage caused during the operation of gasification furnaces and other industrial furnaces.
