Properties and applications of fused cast AZS

The products are produced by corundum and chromium oxide as main materials, formed from casting, after being treated under high temperature, it has high hot strength and good wear resistance, suitable for making the slide rail part of heating furnace.

Fused cast AZS block is tundish well block the most widely used fused cast refractory brick. According to the ZrO2 content, it can be divided into 33#, 36# and 41#AZS.
Fused cast AZS magnesia carbon brick containing 33% ZrO2 is called 33# fused cast AZS; fused cast AZS containing 36% ZrO2 is called 36# fused cast AZS; fused cast AZS containing 41% ZrO2 is called 41# fused cast AZS.
Fused cast AZS is mainly composed of baddeleyite and corundum and their eutectic crystals. High viscosity glass phase is filled in the gaps of crystals. The crystals is directly precipitated monoblock stopper from the molten liquid and well developed. So, it has large crystal particles and stable crystal phase. Except the voids, it has compact structure and better density than the common sintered bricks. The pores are mainly closed pores and the crystals are intertwined each other, so it ladle slide gate has good mechanical properties and wear resistance. The impurities are difficult to invade the bricks. Therefore, this refractory brick has good corrosion resistance. besides, the transformation of ZrO2 at 900~1150℃ when heating or cooling may cause irregular deformation.
Fused cast AZS block can be used in areas in direct contact with molten metals and molten slags. It is the essential material used in the key areas that suffer from severe corrosion.
