Fused Cast Azs Block

Fused cast AZS major include model AZS-33; AZS-36; AZS-41. the different model applicated in different parts of furnaces.

AZS block 33#,a normal refractory material, with the features of very good melting glass resisting, Which seldom produces stone or other faults, and has little possibility to produce bubbles. And it is widely used in glass Indaustrial furnace.

AZS block 36#:has more free baddeleyite crystals in chain structure and less vitreous phase, which further improve the corrosion resistibility and reduce the potential defects in glass, so it is recommended to be used in sections where glass flow is faster and temperature is higher, such as melter sidewall, paving, doghouse, etc.
AZS block 41#:has the most free baddeleyite crystals among the fused cast AZS families, which are evenly distgributed within the block. Its corrosion resistibility is the best and thus it is usually recommended to be used in the most demanding positions to balance the furnace life.

The glass is mainly made of silica sand and soda ash as raw materials which are melted at a high temperature. Glass melting furnaces are thermal equipment for melting glass and are usually constructed of refractory materials. Glass melting furnaces can be divided into two categories: pool kiln and crucible kiln. The pool kiln is the most commonly used kiln type in the glass industry. It is made of refractory materials, and has a flame pool kiln and an electric kiln.
Casting zirconium corundum bricks are commonly known as white iron bricks. It is the most important refractory material to ensure the normal operation of the glass melting furnace. At present, the melting rate of the glass melting furnace at home and abroad is increased, the kiln age is extended, and the fuel consumption is reduced mainly due to the use of the refractory material. The use of fused zirconium corundum brick in the glass melting furnace is to build the upper pool wall, small furnace flat raft, small furnace raft, stone raft and chest wall.
Fused cast blocks usually named zircon corundum brick also name AZS bricks( alumina zircon silica ),according to the ZrO2 content difference ,can be named AZS 5.5 ,AZS 12 .AZS 33, AZS 36, AZS 41 and so on. Beside because this type bricks are produced by special electric furnace by model, we also called this products Fused cast AZS bricks. Also according to the brick if have shrinkage cavities, we call them PT, QX, ZWS, WS.
These bricks are widely used for iron & steel furnace and glass furnace, also chemical industrial furnace, especial in the glass furnace, you will find it usually.

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 Al2O3ZrO2SiO2. 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 33,36 and 41.

TY-AZS33 Description

Fused cast AZS 33 block has dense micro structure which ensures its great resistance in glass liquid, thus you donâ??t have to worry about the solidification and other problems. It is widely applied to glass furnace for superstructure, working pool side wall, paving blocks, feeder channels, tank bottoms, C-shaped block and doghouse crown,etc.

Advantages
1. Compact microstructure
2. Good erosion resistibility to molten glass
3. Good thermal shock resistibility,high compression resistance
4. Barely rendering blister
5. A variety of formats and shapes for furnace different working areas

AZS brick use high purity zircon, alumina and silica as its raw material.

Our fused AZS blocks mainly inclue model AZS-33#, AZS-36#, and AZS-41#. the different models applicated in different parts of furnaces.
AZS brick 33#, a normal refractory material, with the features of very good melting glass resisting, which seldom produces stone or other faults, and has little possibility to produce bubbles, widely used in glass Industrial furnace.
AZS brick 36# has more free baddeleyite crystals in chain structure and less vitreous phase, which further improves the corrosion resistibility and reduces the potential defects in glass, so it is recommended to be used in sections where glass flow is faster and temperature is higher, such as melter sidewall, paving, doghouse, etc.

AZS brick 41# has the most free baddeleyite crystals among the fused cast AZS families, which are evenly distgributed within the block. Its corrosion resistibility is the best and thus it is usually recommended to be used in the most demanding positions to balance the furnace life.

Magnesia chrome brick is an alkaline refractory product, which is made of periclase and magnesia chrome spinel, and is fired at 1600~1800 °C in an oxidizing atmosphere. It can also be made into non-burned brick by chemical bonding agent such as water glass.
According to the raw materials and process characteristics of the products, it can be divided into silicate-bonded magnesia-chrome bricks, direct-bonded magnesia-chromium bricks, re-combined magnesia-chrome bricks, semi-recombined magnesia-chrome bricks, pre-reacted magnesia-chrome bricks Casting magnesia chrome bricks.

With the breakthrough of the suspension preheating and pre-decomposition technology in the cement industry and the increasing size of the equipment, the heat load of the kiln is significantly increased, the rotation speed is accelerated, the alkali corrosion is severe, and the lining life and equipment operation cycle are shortened, thus the requirements for refractory materials. More demanding.
Its performance advantages are mainly manifested in: 1. High refractoriness under load and excellent high temperature resistance; 2. High strength, abrasion resistance, and easy to peel off and erosion; 3. Low thermal conductivity and good heat insulation effect; 4. Strong flexibility and heat resistance Excellent seismic performance; 5, moderate density, reduce the cylinder load.

With the rapid development of the world automobile industry, the production process of automobile rearview mirrors has also made great progress, and then higher requirements have been placed on the performance and quality of the mold bricks.
The glass bending brick has the following characteristics: First, the change of the reheating line is low, because the glass bending brick is sintered at 1050 ° C, which ensures the long-term use of the glass bending brick at 800 ° C. The characteristics of the burning line change to zero and no deformation; Second, the structure is fine, the glass bending brick is formed by micron material mixing by high-speed agitator, and the coarsest material particles in the batch are less than 1000 mesh, sectional structure Very fine; Third, the thermal shock stability is good, the glass hot bending mold brick will not appear any cracks (including cracking phenomenon) during long-term use; Fourth, the processing is convenient, the glass hot bending mold brick is according to user requirements specifications Made, this avoids the problem of large cutting and waste; fifth, the price is low, the price of glass bending bricks is lower than that of similar products.
Glass hot bending mold bricks can also be used in industries such as hot bending glass, hot melt glass and process glass.
