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.
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.
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. The magnesia chrome brick can be used in vulnerable parts of steelmaking electric furnace, RH, DH vacuum degassing device, secondary refining slag line parts such as VOD, LF, ASEA-SKF, AOD, steelmaking converter, cement rotary kiln and glass melting Kiln regenerators, etc.
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.

Magnesium silicate insulation board : The board has a high structural strength, low deformation after sintering, good insulation properties and resistance to moisture. It retains its physical properties during operation at high temperatures. Installation of this board imparts volume stability to the complete lining, reduces the shell temperature of the furnace, and eliminates stresses within the bricks thereby ensuring safe operation of the furnace and effectively saving energy. This product is mainly used for applications in the metallurgical and building industries, for furnace insulation and for fire resistance, etc.. The shell temperature of a ladle in which magnesium silicate insulation board is used as the lining is much lower than that of a normal ladle. The average reduction in shell temperature is 75c and the maximum reduction in shell temperature can be as much as 120c. The use of this board therefore helps to eliminate deformation of the ladle shell and improves greatly the operating environment within the ladle. The rate of temperature loss of the molten steel is lower than that of a normal ladle, typically an average of 0.3~0.5c/minute. This shows that the heat retention of the molten steel is quite high, thereby reducing heat losses and saving energy and also ensuring a smooth continuous casting process due to the constant temperature and casting rate of the steel.
For refractory materials, sintering is very important, whether it is natural raw materials, or synthetic raw materials, have to be burned, to sinter before use, fire-retardant refractory products is to achieve the date of sintering. Unshaped refractory materials in the process of gradually sintering. From a process point of view, sinter is a sturdy, low porosity (almost airless 7L) stone made from a powder at high temperatures. Refractories degree of flexibility of the signs, usually with the object size reduction (the so-called shrinkage), reduced porosity and bulk density increased to measure. Sintering is mainly due to the strengthening of refractory material, the inevitable result of increased contact between the particles. Sintering (intrinsic) has the following processes: changes in the shape of the pore size phase; crystal growth, residual stress (suppression) reduction and equilibrium; liquid phase formation; redistribution of phase space; In many cases, sintering accompanied by multi-phase transformation of certain phases, solid-phase chemical reactions or liquid-phase reactions. The reaction forms a new phase and a solid melt. The final cooling complicates the enumeration process, with some of the opposite processes occurring. Multi-product changes, melt crystallization and crystallization pressure may occur, the formation of the glass phase and other phenomena. Like the lower temperature drop, the refractory material produces stress and often produces macroscopic defects so that the refractory products are discarded. Temperature gradients, temperature change rates, phase and concentration gradients, atmospheres, high frequency field effects, vibrations and other conditions in a refractory body all depend on the temperature. Even within the refractory material. y1 its temperature changes have a very complex phenomenon, can not fully enumerate the occurrence of the process
