Factory Manufacturing High Creep Resistance Pleonaste Brick for Cement Kiln
Introduction:
Pleonaste brick is made with good quality fused magnesite and fused mgo-cr clinker as raw material, shaped under high pressure and fired in high temperature.
Feature:
1. Excellent erosion resistance
2. Excellent thermal-shock resistance
3. High refractoriness
4. Excellent abrasion resistance

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.
