Product introduction of Phosphate high alumina brick
Phosphate high alumina brick is a new environment-friendly refractory, which is composed of ordinary refractory and light insulating refractory. It can meet the daily production requirements of users and save the cost of coal and powder.
Characters of Phosphate high alumina brick
The added insulating refractory can accumulate heat, reduce heat loss, further save fuel and reduce production cost.
After adding the same volume of thermal insulation refractory, the total weight of the furnace lining drops sharply to reduce power consumption and load.
The size of phosphate high alumina bricks depends on the different parts used. In addition to standard bricks, there are also phosphating knife bricks, a multi-functional arc facing brick. Different sizes can also be processed according to drawings.
