Do you Know These Unique Product Features of Zirconium Corundum Bricks?

There are five kinds of raw materials used for zirconia corundum refractory bricks: oxidation, zircon sand, zirconium-rich sand, soda ash, and sand. Zirconium corundum products are widely used in industrial furnaces of metallurgy, building materials, petroleum, chemical, ceramics, glass, pond porcelain, carbon black, non-ferrous metals, refractory materials and other industries.

 

1) The introduction of alumina is generally selected from industrial alumina. The production requires that the water content should be less than 0.3%, the loss on ignition be less than 15%, and about one ton of AZS-33 fused brick should be about 0.62 tons.

 

2) Zircon sand is mainly introduced to dye AZS products, causing coarse crystal sand eyes and also affecting cracking. Therefore, the content should be less than 0.2%. The shadow castings will crack during the cooling process, and the oxidation process of the products will also be affected. The content should be less than 2%, and about 0.65 zircon sand should be required per ton of AZS-33 fused brick.

 

3) Zirconium-rich sand is also called desiliconization. The silica in AZS is all in the zircon, and the insufficient part is supplemented by zirconium-rich sand.

 

4) Sodium sulphate is introduced into sodium sulphate. As a fluxing agent for AZS bricks, two-stage products are generally used. One ton of AZS-33 fused bricks requires about 2Okg of pure city.

 

5) Borax is also a fluxing agent for AZS bricks. About one ton of borax is required for one ton of AZS-33 fused brick.

 

The zirconium corundum brick is made of high-quality zirconium dioxide (ZrO2) and corundum clinker as raw materials. After kneading, molding and dry operation, it is fired in a shuttle kiln at high temperature. The zirconium brick product has compact crystal structure, high bulk density and large capacity, high mechanical strength at normal temperature and high temperature, good thermal shock stability, low reburning shrinkage and high temperature creep, and high chemical stability and resistance. Characteristics such as alkaline medium erosion.

 

Sunrise Refractory zirconium corundum products are widely used in industrial furnaces of metallurgy, building materials, petroleum, chemical, ceramics, glass, pond porcelain, carbon black, non-ferrous metals, refractory materials and other industries.

Zirconium corundum brick procurement precautions mainly have three sides:

1, indicator performance

It is well known that the properties of refractory bricks of different materials are different, as is the filling of corundum bricks. The raw materials used in corundum bricks are different, and their performances are also different, such as brown corundum, white corundum, black corundum and so on. Therefore, when purchasing corundum bricks, the corundum bricks provided by the customers require the refractory brick manufacturers to provide the same quality inspection report after production to ensure that the performance of the corundum bricks can reach the customer's needs.

 

2, size specifications

When purchasing the corundum bricks, there are standard bricks and shaped bricks, and some of them need to be designed and produced by refractory brick manufacturers. Therefore, it is necessary to ensure that the size of the corundum bricks produced meets the requirements of the drawings and can reach the construction of the site. When processing, it is processed and marked, and it must be marked when it is shipped. It is convenient for on-site construction and masonry.

 

3, zirconium corundum brick manufacturer

Corundum brick belongs to refractory brick. As a purchaser of corundum brick, the purchase of general corundum brick needs to provide information on the performance and size specifications of corundum brick. The corundum brick manufacturer can produce and process it, but for the more suitable corundum brick, such as electricity Melted corundum bricks and chrome corundum bricks are not processed by each refractory brick manufacturer. These corundum bricks require specific refractory brick formulas and processing techniques. Therefore, these are clearly understood when selecting fire brick manufacturers.
