Kiln Furnace Zircon Corundum Brick, Zirconium Ceramic Bricks
Introduction
Zircon corundum brick is adopts alumina powder and zircon sand as raw material, after mixing, shaping, drying, sintering at high temperature in shuttle kiln, the whole process is finished.
Features of zircon brick:
- Dense crystal structure.
- High bulk density.
- High mechanical strength at normal and high temperature.
- Good thermal shock resistance.
- Low creep and low permanent liner change rate.
- High performance of chemical stability and alkaline medium erosion.

Manufacturing Process Flow:
First, qualified raw materials enter to our raw materials warehouse
Second, all materials including fine powders, aggregates, binding agent are batched according to the technical agreement.
Third, finished raw materials is shaped by 630 tons pressure machine or 2500 tons automatic hydraulic pressure machine.
Forth, green bricks is dried in the dry kilns between 40℃ and 120 ℃, and then sintering in high temperature according to the firing curve.
Last, check the quality of finished refractory bricks and qualified products are packed as request.
