Magnesite Alumina Zircon Bricks

Type:HY
Supply Ability:150t/d
Raw materials:Magnesite Alumina Zircon
Delivery:15-30days
Application:cement, electric power, metallurgy, chemical industry and other industry

 


By adding Lan2O3 & ZrO2 into magnesite spinel brick, the performance is highly improved comparing with conventional refractory. It is the optimum choice for modern cement kiln due to outstanding abrasion resistance & chemical attack resistance.

Application

1.Cement burning zone & Transition zones with increased thermal load

2.LTZ/CBZ/UTZ

3.Rotary Kiln with alternative fuel fired

Physical properties

a.Low thermal conductivity

b.High flexibility

c.Coating friendly

d.High chemical attack resistance

e.High refractoriness

Raw materials

1.High grade sintered magnesia

2.Spinel

3.Lan2O3 & ZrO2
