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
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.

What's Fused Cast
The term Fused Cast refers to a manufacturing process in which the ceramic bonding is obtained by the solidification of a mixture which has been melted in an electric furnace and cast in liquid state into molds.
Fused Cast AZS Blocks Introduction
AZS fused cast block is also called fused cast block which is abbreviated as AZS because it contains Al2O3ZrO2SiO2. Fused cast AZS block is made from pure alumina powder and Zircon sand (composed of 65% zirconia and 34% SiO2). After Alumina powder and zircon sand melting in electric furnace, they are cast into various molds and cool themselves down to become white solid. Because of the different content of Zirconia from 33%-41%, our fused cast AZS blocks can be divided into three types 33,36 and 41.
