Furnace Bricks Good Erosion Resistance Phosphate Refractory Brick for Rotary Kiln
Introduction:
Phosphate refractory bricks is made by a special process and the use of chemical additives based on ordinary phosphate bonded high alumina brick, with improved wear resistance and load softening temperature.
Feature:
High refractory temperature
High strength
Good wear resistance
Good resistance to acid corrosion.
Technical Index:
| Item | Unit | Special Phosphate Compound Brick |

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.
