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
