High Alumina Refractory Castable By Henan Hongtai Kiln Refractory Co., Ltd.

With the support of our expert, our company is dedicated Exporter, Manufacturer & Supplier of High Alumina Refractory Castable in Zhengzhou, Henan, China.
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), together with the addition of appropriate additives to achieve and exceed the performance of ordinary cement castables.
Refractory fire castable,The main features of high alumina castables are as follows:
1. Refractory fire castable,The low cement content in the castables, that is, the low calcium oxide content, reduces the production of low melting materials in the materials, thereby improving the refractoriness, high temperature strength and slag resistance of the products.
2. Refractory fire castable,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. Refractory fire castable, 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.
