Factory Directly Sale High Strength Alkali Proof Castable For Industrial Kilns and CFB boier
Alkali proof castable is the most used of all the castable applied in the cement rotary kilns. Because when the temperature is at 1250℃, it crusts forming a protective layer, preventing the erosion and infiltration to the casting body of the basic flow, slags or other materials. Due to alkali proof castablesresistance to alkali gas and clinker or slags with long service life, high strength, low bulk density, and high refractoriness, refractory alkali proof castable is widely used in the industrial furnaces that are eroded by alkali materials, such as the kiln hood, preheater system, decomposition furnace.
Alkali proof castable has high liquidity and is suitable for unshaped refractory materials made with pouring type. Alkali proof refractory castable has various features of high temperature resistance, high mechanical strength and strong acid erosion resistance for all kinds of furnaces and kilns application. Alkali proof castable can react with metal oxide at high temperature generating high viscosity liquid products, which forming a glaze layer avoiding the penetration and erosion of the alkali melting metal.
.Long service life,
.High strength,
.Low bulk density,
.High refractoriness.
Alkali proof refractory castable is made of refractory aggregates, binders and alkali resistance powder. Its aggregates are ceramsite, sticky soil clinker, waste porcelain material, high strength expanded perlite, etc. together with calcium aluminate cement and sodium silicate as binders.
According to different conditions and environments, alkali proof castable can be divided into light alkali proof castable and heavy alkali proof castable. Those with porosity greater than 45% are light alkali proof castable and those with porosity less than 45% are heavy alkali proof castable. The heavy quality alkali proof castable can be divided into medium temperature alkali proof castable and high temperature alkali proof castable.
