Product Introduction
Product Details
Production method:
Anti-spalling high-alumina brick is made of high-alumina bauxite as the main raw material, adding zirconia-containing materials or other raw materials, and is formed by a brick press, dried and calcined at high temperature according to a certain ratio. Anti-spalling high alumina bricks are divided into two categories according to their chemical composition, one is containing zirconium dioxide (ZrO2), the model is GKBL-70; the other is not containing zirconium dioxide (ZrO2), the model is KBL-70.
Product features: anti-spalling high alumina brick, not only has the characteristics of strong anti-spalling ability, good thermal shock resistance, and strong ability to adapt to the environment. At the same time, it has the characteristics of high load softening temperature, high temperature strength, alkali resistance and clinker erosion, high temperature wear resistance, anti-crust, ring and low thermal conductivity.
Product use: anti-spalling high alumina brick, widely used in a wide range of fields, has been widely used in China's new dry kiln, Libour kiln and wet kiln, the parts used include kiln door cover, rising flue, cooling belt, safety belt, transition belt, cooling machine back wall and side wall and beam bending top and other parts.
