Castable Refractory

 

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.

 

 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.
