Chrome corundum brick is alumina - chrome oxide as the main raw material production of high-performance chrome corundum brick, has the characteristics of high refractoriness, great strength, good thermal shock stability, strong ability to resist erosion.
Chromium corundum brick raw material is used by the ratio of alumina and chromium oxide according to certain proportion, go through high temperature melting synthesis of a solid solution. Using special refractory production technology made of refractory brick, can improve internal quality of the product, improve the high temperature performance of products.
Feature
1.The refractory properties of chrome corundum brick
In high purity corundum material add Cr2O3, no matter how much the amount, not only will not reduce the fire performance of materials can make refractory performance of material improved.
2.The strength of chrome corundum brick.
The products in the process of burning, between particles and fine powder, between powder and powder are formed Al2O3 - Cr2O3 solid solution, calcium solid solution like bridge connect fine powder with particles together, make the strength of the material is greatly increased.
3.Thermal shock resistance
Add Cr2O3 in corundum, when Cr2O3 content is 10% ~ 66%, material of thermal shock resistance decreased with increasing content of Cr2O3, namely the Cr2O3 content low chrome corundum brick, the thermal shock stability is better than Cr2O3 content high chrome corundum brick.

AZS Bricks, Alumina-Zirconia-Silica (AZS) refractories, belong to sintered ZrO2_Al2O3_SiO2 products family along with Zircon Mullite, Bonded AZS, Zirconia Corundum, and Rebonded Fused Mullite bricks. Sintered ZrO2-Al2O3_SiO2 products such as AZS have good resistance to alkali vapor and thermal shock. Mainly used in glass furnaces, they can withstand aggressive conditions in contact with molten glass. Typical applications are superstructures, skew blocks, wall bricks and upper-checker in regenerators, paving, sub-paving, and forehearth blocks in float glass furnaces. 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.

Alumina hollow ball is a new kind of high temperature heat insulation material, it is placed in the industrial alumina content of more than 98% in the arc furnace high temperature melting, using compressed air to blow liquid alumina into air ball alumina hollow ball.Alumina hollow ball can be made into various shapes of products, the highest temperature of 1800 degrees Celsius, the mechanical strength of the products is high, several times of the general light products, and the volume density is only half of corundum products. The characteristics: It is characterized by high melting point, good thermal stability, high hardness, good wear resistance, high mechanical strength, good electrical insulation and corrosion resistance Application: Widely used for finalizing, non-finalizing refractory materials, refractory casting binder, wear-resisting abrasive tools, high purity refractory fiber, special ceramics, electronic ceramics, structural ceramics, stainless steel, granite and other decorative materials mirror polishing.It can meet the requirements of users with different USES and different process conditions.
Zircon Corundom Mullite bricks are made of raw materials such as high-grade mullite grog and Australia imported zircon sand, which is melted and casted in high temperature electric furnace. It is mainly used in areas that require high abrasion and temperature resistance, such as gliding rail bricks in steel pusher metallurgical furnace, the tapping platform (tapping spout) fortapping platform (tapping spout)style walking beam furnaces, and also as the interior for destructors.
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.
