The use of refractory cement in boiler construction is also very large, and refractory cement is also a refractory castable that we need most. Refractory cement is also called aluminate cement. The raw material of aluminate cement is bauxite and limestone. It is made of calcined, with calcium aluminate as the main component, clinker with alumina content of about 50%, and then ground into hydraulic cementitious material, which is also a kind of special cement. The thermal stability of refractory cement is good. The aggregate is almost all clinker. The expansion and the shrinkage of the cement are low. Therefore, the thermal expansion of the masonry is smaller than that of the brick, the temperature stress is relatively small, and the structure is also various. Reticulated, needle-like, chain-like crystalline phase, strong resistance to air temperature, for example, used to cast soaking furnace mouth and furnace cover, the furnace age can be extended to one and a half years; and the fire resistance of refractory bricks and the same The texture of the refractory brick is similar, but because the refractory cement does not have a net more sintering, the initial blasting shrinks larger, so the load softening point is slightly lower than the refractory brick, but as a whole, the refractory cement is still due to the refractory brick.

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

ZIBO SK refractory mortar is a new kind of paste-like bonding material which is formed particularly from specially sorted powder made from the identical raw materials and classification temperatures in light with the brick utilized in furnace and their refractory grades. During the process of production, it undergoes chemical reaction and stirring-up with added inorganic bonding agent and additives. ZIBO SK refractory mortar can be classified into four categories according to its service temperature in normal circumstances and they must be used to support the lightweight mullite brick subject to the same class. Category Air setting refractory mortar Grade-23 Grade-26 Thermalâ??hardness refractory mortar Grade-28 Grade-30 Features High bonding performance for bricks engineering Excellent sealing capability, resistance to erosion High refractoriness under load Outstanding efficiency in reducing the slag Ensure well-sealed joints for convenient installation Consistency and bonding effectiveness Typical Applications Necessary auxiliary materials for insulating Firebricks in the furnace lining
