Fused cast AZS 33 block descriptions
Fused Cast AZS blcok are the most widely used materials both in glass melting furnaces and reheating furnace in the steel mill.Fused cast AZS 33 block has dense micro structure which ensures its great resistance in glass liquid, so you don’t have to worry about the solidification and other problems. Fused cast AZS block widely used for glass furnace for superstructure, working end side wall, paving blocks, feeder channels, tank bottoms, C-shaped block and doghouse crown,etc..
Fused cast AZS 33 block features
1. fused cast block casted by melting raw material in the electric arch furnace at themperature more than 2300 degree, then cooling and solidification.
2.Fused cast AZS block have Strong glass corrosion resistance and high thermal shock stability.
3. Better wear-resistance,slag-resistance and alkali corrosion resistance.
4.Produced by high-purity raw material, barely no pollution.
5.Huachen company fused cast blcok with top quality, long service time.
Fused cast AZS 33 block casting methord
used cast AZS 33 block have four cast method, with different method fused cast AZS 33 block has different usage.

(a) under PT method, fused cast AZS 33 block usually made into tuckstone, nozzle block, feeder channel , breast wall and other hole bricks;
(b) using QX method, fused cast AZS 33 block mainly be made as tank wall block;
(c) (c) using ZWS and WS. AZS-33# brick usually be made as C-shape brick, smelting tank block and tank side wall brick.
