Phosphate-bonded high alumina brick is a kind of chemical bonded refractory brick made of dense super grade or first grade high alumina clinker as the main raw material, phosphate solution or aluminum phosphate solution as the binder, after semi-dry press molding, heat treatment in 400~600. It belongs to the non-fired brick, in order to avoid the product contraction in the process of use, the general need to introduce heating expansion raw materials, such as blue pinstone, silica and so on. Compared with the ceramic combination fired high aluminum brick, its peeling resistance is better, but its softening temperature under load is low, corrosion resistance is poor, so a small amount of fused corundum, mullite, etc., should be added to strengthen the matrix. Phosphate-bonded high alumina brick is widely used in cement rotary kiln, electric furnace top and other furnace parts.
The Phosphate-Bonded High Alumina Brick Used In Cement Rotary Kiln made by Zhengzhou Caihua Kiln Masonry Installation Co., Ltd has good high temperature resistance, fire resistance temperature is more than 1770 degrees, can withstand relatively high temperature, in the case of high temperature fluctuation does not have a great impact. Good thermal stability, rapid cold and rapid heat resistance, in the temperature change does not appear stratified spalling. Chemical corrosion resistance, at 400-600 temperature intensity CO atmosphere is, does not occur bursting spalling. Good wear resistance, high compressive strength. Mainly used in cement rotary kiln kiln and cooling belt, cooling machine and cement machine shaft kiln bell mouth and other thermal equipment.
Zhengzhou Caihua Kiln Masonry Installation Co., Ltd has near 30 years experience is manufacturing refractory products and do installation for various furnace, The products exported to middle east, africa, Europe, South America.,etc, which have built long-term cooperation with customers and helped them improved the production efficiency. We sincerely hope the long-term cooperation with you!

Advantages of Phosphate Refractory Brick
Higher strength and good wear resistance.
Good chemical resistance. (The alkali resistance is better than clay bricks and high alumina bricks)
Good thermal shock resistance.
The load softening temperature is higher.
Customerize mould according to different size requirements for free
Application of Phosphate Refractory Brick:
Transition zone of the rotary kiln, the kiln mouth, the kiln door cover, the lining of the cooler and other parts of the refractory brick that are easy to loose and fall.
