    What is  High Strength Alkali Proof Castable

    Alkali resistant castable belongs to the silicate aluminum refractory castable. It 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.

    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 its resistance to alkali gas and clinker or slags with long service life, high strength, low bulk density, and high refractoriness, alkali resistant castable is widely used in the industrial furnaces that are eroded by alkali materials, such as the kiln hood, preheater system, decomposition furnace.

    High Strength Alkali Proof Castable Features

    High strength alkali proof castable is featured with strong resistance to erosion of alkali metal oxide, such as K2O and Na2O. It is a kind of alkali resistance hydraulic castable. Alkali power can be high siliceous refractory materials, which 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.

      Classifications Of High Strength Alkali Proof Castable

      Alkali proof refractory castable can be classified into light and heave. The former means its porosity is greater than 45%, while that of the latter is less than 45%. Generally speaking, the chemical compositions of light alkali resistant refractory castable are Al2O3 30% ~ 55% and SiO2 25% ~ 45%. While the heavy alkali resistance refractory castable uses calcined bauxites and chamotte as the aggregates binder and alkali resistant powder are the same with that of the light alkali resistant castable. The main chemical compositions are Al2O3 35% ~ 60%; SiO2 35% ~ 60%. Light alkali proof refractory castable is mainly used in the preheater roof, kiln shell, and the alkali erosion area of kiln as the alkali resistant and heat insulation linings. Heavy alkali resistant refractory castable are mainly used in the rotary kiln for the calcined alumina, and the head, end, preheater, discharge hole and tuyere of the cement rotary kiln.
