Resistant to Spalling High Alumina Refractory Brick for Cement Industry
The Description:
Anti-spalling high alumina brick is a special grade high bauxite clinker and synthetic material containing ZRO2 as raw materials, according to a certain ratio of high pressure molding made of fired products, the product has strong anti-spalling ability, and has resistance to potassium, sodium, sulfur, chlorine and alkaline salt erosion, low thermal conductivity and other properties, is the ideal material for cement kiln transition zone and decomposition zone, the remarkable feature of the product is good heat shock resistance Good ability to adapt to the environment. It is mostly used in rotary pre-heat or decomposition furnace and grate cooling machine.

Product feature:
Anti-peeling high aluminum brick is a new type of high aluminum material specially produced for cement kiln lining in China. It has excellent thermal shock stability, high softening temperature under load, high strength at high temperature, alkali and clinker erosion resistance, high temperature wear resistance, anti-peeling, anti-skin, ring formation and low thermal conductivity. It has been widely used in China's new dry kiln, Libo 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. Almost all parts of the kiln were successfully applied.
Anti-spalling high alumina brick is a new type of refractory material created in China, which has reached the international advanced level. This brick has excellent physical and chemical indicators: thermal shock stability > 40 times at 1000 degrees, refractoriness of 1780 degrees, load softening temperature of 1470 to 1520 degrees, low thermal expansion rate, small thermal conductivity,
It is resistant to wear and corrosion and can replace all parts of refractory materials outside the large new dry kiln firing zone.
Application:
It is widely used in China's new dry kiln, Libo 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.
