Pleonaste Brick
Features:
This product belongs to new chrome-free basic refractory for large rotary kilns developed by our company. It is produced with high quality synthetic spinel materials and special technical process. The product is characterized by high crushing strength, good thermal shock resistance, good thermal creep, high refractoriness under load, also has the characteristics of direct bonded magnesia-chrome brick (easily adhering the furnace crust).
The production on pleonaste brick has solved the environment pollution problem on sexavalent chrome when using magnesia-chrome brick in the cement kiln. It's the perfect substitution for magnesia-chrome brick.
The development and application of CUNSE Company's pleonaste brick meets the trends of magnetite-chrome brick quit the historical stage in the cement industry.
It also meets the demand of chrome-free basic refractory in cement industry under the new environmental-friendly situation.
Applications:
Burning zone of large dry-process cement rotary kiln.
