Tianjin(xingang)Fused Cast AZS Block Introduction
Fused Cast AZS Block is also called electro Zircon corundum block, which is abbreviated as AZS because it contains Al2O3,ZrO2and SiO2. Acording to the different content of Zirconia 33%-41%, fused cast AZS block can be divided into three types: AZS-33#, AZS-36# and AZS-41#. 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 are melted in electric furnace, they are casted into various molds and cool themselves down to become white solid.
Fused cast AZS refractory materials are among the best, thus being widely used in the structure of glass melting furnaces. And different types are used in different parts of glass melting furnaces as each type of fused cast AZS block has a different corrosion resistance. To give you only one example, the fused cast AZS refractory containing 36% ZrO2 has an excellent resistance to corrosion. This makes it a very good choice for the glass contact parts of the melters. It is also very effective in paving blocks and side walls.
Fused cast AZS block is mainly applied to all the melting pool where directly gets in contact with the glass liquid such sidewall, paving of working end, doghouse bricks, super structure, fore hearth, throat, bubbling brick, corner brick, etc.
Fused Cast AZS Block Casting Method
PT: Normal casting, cavities are located under the casting scar
QX: Tilt casting, cavities are located at the rear bottom side
ZWS: End casting, with little cavities which located at the bottom of block
WS: Void free casting, no cavity since the cavity zone is cut off
There are some other casting methods like RX, RL, RA, etc., HUACHEN can make the products as per customers' requests.

Fused cast AZS block applications
Fused cast AZS block is widely used for the whole glass furnace, you can find it everywhere of the furnace, such as bottom of melting tank, sidewall of working tank, superstructure, feed port, doghouse, paving block, front wall, back wall, top crown, refiner bottom, side wall and so on.
Quality Assurance
The quality assurance system consists of the following steps:
a.Inspection and Control of incoming raw materials:According to the chemical content,raw materials are classified into different levels to ensure quality of brick first.
b.Inspection and control of the process:During the production,every brick will be weighed twice strictly to reduce the error of weight .
c.Inspection of product Standardization of quality of each product by process control and experimentation.
d.Taking corrective measures whenever deviations are noted.
e.Quality audit by quality management.Before delivery, the inspectors will inspect the size,appearance,physical and chemical properties of brick again in factory.
