Phosphate high alumina brick is a kind of new type environmentally friendly refractory, composed of normal refractory and light weight insulation refractory to meet the daily production requirements and save costs on coal and powder of users.
- The insulation refractory added in accumulates heat to reduce heat loss, furthermore, to save fuel and lower the production cost.
- After adding into the insulation refractory at the same volume, the total weight of the kiln lining declines dramatically to decrease the consumption of power and reduce load.
The dimensions of the Phosphate high alumina bricks depend on the different parts used. In addition to standard bricks, there is phosphate knife brick, a versatile arc facing brick. It is also possible to process different sizes according to the drawings.
