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.

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.

Corundum and corundum-mullite AL2O3 porcelain balls and porcelain lining bricks are most suitable to be used as grinding media and drum linging of various grinding equipments because of its excellent properties such as high strength,high hardness,high abrasion resistance, high gravity, small size,high temperature resitance. Application: It is mainly used for non-metalmineral products extra refining, it is ideal grinding media for stirring grinding, sand grinder and vibeation grinding. And it is widely applied in ceramics, paint, ink coatings,dyes, rubber and power industries. Performance: 1. High density and hardness,impact resistance, low loss rate, smooth surface and no contamination to products. 2. Fine chemical stability, anti-corrosion.. 3. Under condition of appropriate ball size ration, it can achieve high grinding efficiency with material results D¡Ü2¦Ìm. 4. High performance and low price. Wooden box.
Fused cast magmalox block, also named fused cast wear-resistance block, fused cast skid rail block, and fused cast zirconia mullite block. ZS Refractoriesâ?? fused cast magmalox block uses high quality bauxite, zircon sand and other raw materials, melting in an electric arc furnace at a high temperature ranging from 2000-2500�°C. The molten product then casted in molds, and kept to anneal for almost two weeks. It has advantages of compact structure, wear-resistance, impact resistance, strong thermal shock resistance, good corrosion resistance, slag resistance, and long service life. Being applicable in the areas of metallurgical pusher type reheating furnace, steel outlet tank, the lining of refuse incinerator, our fused cast magmalox block is also served as the key part of glass melting furnace.
