Product Description
refractory low cement castable/high alumina castable


High aluminum castable: It is a kind of castable with a cement content of less than 8%. Unlike ordinary refractory castables, most of the calcium aluminate cement in the matrix is replaced by ultra-fine powder (Ecken), and with the addition of appropriate additives to achieve and exceed the performance of ordinary cement castables.castable 011.jpg

 The main features of aluminum castables are as follows:
1. The low content of cement in the castable, that is, the low content of calcium oxide, reduces the generation of low-melts in the material, thereby improving the refractoriness, high-temperature strength and slag resistance of the product.
2. The mixing water consumption of the castable is only about one-half of that of the ordinary castable, thus increasing the compactness of the castable and reducing the porosity.
3. After forming and curing, the generated cement hydrate is less. When heating and baking, there is no large amount of water leakage, which reduces the medium temperature strength. However, as the temperature increases, the material gradually

sinters and the strength is continuously improved.


The lightweight castable is made of aluminate cement high alumina fines, ceramsite, plus a number of additives. The product has light volume, high compressive strength, acid and acid gas corrosion.

It has the characteristics of heat insulation, heat preservation and low water absorption. It is easy to construct and is the most ideal product for the construction of alkali-resistant parts under high temperature.

Good workability, strong adhesion, long initial setting time and long operation time, strong strength growth, strong impermeability, no need for acid treatment, easy to ensure the dense and fullness of masonry gray joints, can significantly improve the chimney lining The airtightness, integrity and corrosion resistance of the lining are ideal cementing materials for high chimneys, high temperature flue and duct lining.

They can also be used for acid resistance tanks and tanks in petroleum, chemical and nonferrous metallurgy industries. engineering.

 Acid-resistant bricks, acid-resistant clay and wipes acid-resistant bricks, acid-resistant clay and wipes are refractory materials specially developed by our factory for heat preservation of power station boiler chimneys and heat network pipes. It has acid corrosion resistance, temperature resistance and heat resistance stability. The construction is convenient.castable 03.jpg
