Anti-spalling high-aluminum brick

Introduction

Anti-spalling high-aluminum brick is made of high-grade alumina bauxite clinker and ZrO2 sand, by high-pressure molding and high temperture sintered.

Advantages:

Strong anti-spalling ability, strong thermal shock resistance, low thermal conductivity, excellent erosion resistance

Application:

Pre-heating zone of cement kiln, lining of decomposition furnace, bottom area of the great cooler
