Product Description

AZS33: fused zirconium corundum brick

The compact microstructure of AZS33# zirconium corundum brick makes it resistant to glass erosion and is not easy to produce stones or other defects in glass kilns.It is the most widely used product in glass kiln, it is mainly applicable to the upper structure of melting pond, the wall brick of working pond, the paving brick, the material road and so on.

AZS33 is one of the most widely used and widely used tea products in AZS series. It has superior performance in preventing the glass liquid from being polluted.It is widely used in the pool wall, bottom, upper structure and feeding channel of glass kiln.

Fused zirconium fused alumina brick AZS36# :

In addition to the same eutectic body as AZS33# fused zirconium corundum brick, no. 36#AZS brick is suitable for areas with high liquid glass flow rate or high temperature because more chain locked zirconia crystals are added and the content of glass phase is low, so the corrosion resistance of no. 36 fused zirconium corundum brick is further enhanced.

AZS36 is an excellent product in the melt casting AZS series. It has high anti-glass erosion performance and low pollution performance.

AZS41: fused zirconium corundum brick

The AZS41# fused zirconium corundum brick not only has the eutectic crystals of silica and alumina, but also contains more uniformly distributed zirconium oxide crystals. In the zirconium corundum brick system, its corrosion resistance is the best.Therefore, the key parts of glass kiln are selected to balance the life of these parts with that of other parts.

AZS41 is the most excellent product in the series of molten AZS. It has the characteristics of high corrosion resistance of glass liquid, high leakage temperature of glass phase, and extremely low pollution to glass liquid.It is widely used in the hot spots of glass kiln, such as the pool wall, the feed inlet corner, the flow hole, the kiln canning, the bottom bubble and the whole electric melting furnace.

Characteristics of fused zirconia corundum bricks for glass kiln

Ordinary glass melting furnace wall bricks generally use a shallow pool structure with a thickness of 250mm and a height of about 1350mm. The wall bricks are made of fully oxidized obliquely cast fused zirconia corundum. Generally, 36#AZS is used for the melting zone, 33#AZS is used for the clarification zone, and 41#AZS is used for the corner. Under the same quality conditions, the high-grade bricks are more resistant to erosion, but the high-grade bricks are prone to bursting when the residual amount of erosion is less than 50 mm, and also designed as a layered structure or a deep pool structure. With the increase of kiln age and the use of lower layer insulation and bubbling, the erosion of the lower pool wall is more, and it is not easy to inspect. Some manufacturers have thinned the lower pool wall when discharging water, so the quality of the lower pool wall should also be taken seriously. In order to gradually extend the life of domestic glass melting furnaces, the production technology of fused zirconium corundum bricks can be improved, and the use of pool bricks is also essential.

Characteristics of fused zirconium corundum brick

There are many domestic enterprises producing fused refractory materials for glass kiln, and the product quality level and price difference are also very large. Many domestic manufacturers have great room for improvement in appearance quality, composition design, casting process and dimensional accuracy. The quality of the brick directly affects the life of the pool wall, especially the crystal phase structure, glass phase content and processing accuracy of the brick. Due to the compact structure and low porosity, the fused refractory material has a high Young's modulus and a high brittleness below 800 °C. The cold compressive strength is very large, greater than 350 MPa, but the tensile strength is only about 20 MPa. In the case of impact and uneven heating, when the tensile stress caused by the temperature difference is too large and the volume changes too fast, there is no pore as a buffering effect, and it is easy to burst.

Produce Process

production process

1)Raw material to factory→checkout→burdening→stirring→mixing→taking out the raw material,
2)Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment.
2.Quality Assurance
1)Going out the furnace→checkout→packing→qualified product→putting in storage→sale,
2)The process from raw to product are strictly tested by equipment.
1.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.
2.Inspection and control of the process: during the production,every brick will be weighed twice strictly to reduce the error of weight .
3.Quality audit by quality management: inspection of product standardization of quality of each product by process control and experimentation, taking corrective measures timely whenever deviations are noted.
4.Before delivery, the inspectors will inspect the size,appearance, physical and chemical properties of brick again in factory.
