Evolution of the binding mode of amorphous refractory materials ramming mass
 In the amorphous refractory materials, easy to mechanical construction is the pouring material and spray coating material, so always be able to get stable development is the pouring material and spray coating material,As to the variety of unshaped refractory materials in Japan as an example, from 1955 to 1986 of casting materials and spraying coatings production continues to grow, while other unshaped refractory material is on the decline. In 85 years, has accounted for the development of castable unshaped refractory material 40%. in other countries are also similar, so this paper mainly introduces the evolution of castable way.
Castable is the first aluminum silicate castable with aluminous cement, due to the high CaO content of alumina cement, a2lo3 and SiO2 reaction of c2as or cas2 low melting it ash and aluminum silicate castable aggregate, greatly reduce the aluminum silicate castable refractory and high temperature performance
General use only 1300 degrees below. So before and after 60s the development of low calcium aluminate cement and calcium aluminate cement, the mineral is in Cao? 2a2lo3, CaO content of calcium aluminate cement in the 33 - 35% down to 21-25%, it will use the high temperature aluminum and corundum aggregate set castable material made of 1350 DEG to 1450 DEG -1600 DEG.
However, the low calcium aluminate cement and calcium aluminate cement, there is a certain amount of Cao into the refractory castable, affect the high-temperature structural strength and other properties at high temperature, so in the past ten years, the foreign research is dedicated to the development of low and ultra-low cement refractory castable (4) (5) so, no cement castable to calcium aluminate cement pouring amount ,This series of evolution process, make the refractory casting material high temperature application technology has been greatly improved, so that the application effect is greatly improved.
But in the absence of cement castable castable, chemical combination also has some shortcomings, as binders for chemical combination with phosphate, sulfate, silicate is not large, the bond will not decompose volatile harmful gases in use (p205, SO2), equipment corrosion, pollution the environment is not convenient to use (most before using tyingor material), or how much it will bring other impurities castable high temperature performance(such as silicate binder in Na2O, K2O, etc.) and condensed with castable, because condensation combined with materials used can be castable with ingredients available plus a small amount of ultra fine powder of coagulant or composition of sol with minimal speed coagulant, so you can not. It may also form a structure directly combined with self binding or in use, so as to improve the structure of high temperature strength of the material, at the same time with castable superfine powder can greatly reduce the forming of the water, reduce the porosity and improve high-temperature melt infiltration and erosion.

Taurus Refractory ramming mass Factory mainly engaged in professional manufacturer of development, production and sales of the refractory mixture such as melting copper, aluminum and zinc furnace lining. And supply castable refractory for copper smelting, ramming mass for molten copper,fire clay,refractory mortar, refractory cement ,refractory mixture, refractory concrete and silica sand for copper smelting.
