High Alumina Ancher brick wear resistant 2.4g/cm3 for furnace top
High Alumina Ancher brick manufacturered by us uses high standard bauxite, fused alumina, sintered mullite as raw material and combines mocromist, several additives.
High Alumina Ancher brick is the refractory brick used to support the stress between the roof structure. Therefore, due to the furnace reactive gas and heat leakage, will damage the metal hanging pieces, resulting in roof collapse accident.
High Alumina Ancher brick has the following masonry points:
1. Bricks from both sides should be coated with mud carefully, to prevent leakage of gas from the top of the furnace;
2. Should be the top of the puzzle, to ensure that the size of the joints, the correct determination of hanging metal parts;
3. The hanging part of the brick should not be damaged (give full play to the role of hanging metal parts);
4. The general use of air hardening mud (to prevent the mud from the furnace caused by gas leakage);
5. Between the furnace body and anchor brick should be set aside between the expansion joints.
