Anti-spalling high alumina brick
Introduction
Anti-spalling high alumina 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
