Overview

► What's Fused Cast 

The term Fused Cast refers to a manufacturing process in which the ceramic bonding is obtained by the solidification of a mixture which has been melted in an electric furnace and cast in liquid state into molds.

► Fused Cast AZS Blocks Introduction

AZS fused cast block is also called fused cast block which is abbreviated as AZS because it contains Al2O3-ZrO2-SiO2. Fused cast AZS block is made from pure alumina powder and Zircon sand (composed of 65% zirconia and 34% SiO2). After Alumina powder and zircon sand melting in electric furnace, they are cast into various molds and cool themselves down to become white solid. Because of the different content of Zirconia from 33%-41%, our fused cast AZS blocks can be divided into three types AZS—33#,AZS—36# and AZS—41#.


 

► Advantage: 

1. AZS block has passed ISO
2.erosion-resistance to glass metal
3.low pollution

► Features:

1. Strong glass corrosion resistance and high thermal shack stability.
2. Good RUL, wear-resistance, dregs-resistance and alkali corrosion resistance.
3. The products are adopting superior material, with process by special arc furnace forming it. This fused cast technology got nearly no suffer from electrode pollution.
 
According to above, they can be used at parts where chemical erosion is serious and temperature changes frequently, can be widely used in the lining of glass furnace, the chemical industrials, metallurgical furnace
 
Our company can produce serious specification fused cast 33#, 36#, 41#AZS block for glass furnace and its output is over 5000tons per year. In the enormous working premises—more than 6600square meters, there are one 5tons outside cooling electric arc furnace, high-power transformer, thaw craft with computer control system and internal advanced fused cast refractory umeral control grinding equipments according to its body producing ability.
