Characteristics of fused cast refractories for glass melting furnaces

2019-09-17 15:52:21

The refractory material for glass melting furnace is mainly fused cast refractory material. On the one hand, the smelting and casting process facilitates the manufacture of large-scale products, which is beneficial to reduce the cracking of brick joints and along the brick joints; on the other hand, the fused casting materials rarely contain open pores, and the molten glass is difficult. Invade inside the material. Therefore, the molten cast material has an incomparable erosion resistance of ordinary sintered refractories. However, the erosion resistance of different fused refractories is still very different. Therefore, refractory materials should be used reasonably according to the furnace location and material properties.

AZS Brick, also called Fused Cast Alumina-Zirconia-Silica Refractory Brick for sale in Manufacturer sunrise refractory, belongs to a kind of high-grade fused cast refractory bricks with high quality and best uses in glass furnace.

AZS Brick, solid with white color, is made of pure alumina powder and zircon sand containing about 65% ZrO2 and 34% SiO2 content that are injected to be mold after being melt in the electric melting furnace. Its petrographic structure is composed of eutectoid and glass phase from corundum and zirconium inclined stone.

AZS Brick actually is Fused Cast Alumina-Zirconia-Silica Refractory Brick that including three main chemical components of Al2O3, ZrO2 and SiO2. Fused cast AZS Brick is manufactured under the high temperature of 1900~2000 degree through melting and molding.

Test of Fused Cast AZS Brick

AZS Brick common specifications of refractoriness, reheating linear shrinkage and expansion, refractoriness under load, true density, cold crushing strength, apparent porosity, thermal shock resistance and specific resistance that generally are provided by professional fused cast AZS bricks manufacturer for user department.

Fused Cast AZS Brick can directly touch with high temperature molten metal and slag.
