High Alumina Castable Introduction

High alumina castable, also named as  high alumina refractory castable, appears to be like powder or sand. Basically a certain portion of binders is added into the raw material to make the castable. The product have a high fluidity, so they can be shaped into any forms through casting, and this is why it is called “castable”. High alumina refractory castable have the characteristics  high desity, low porosity rate, good hot strength, high refractoriness and high refractoriness under load. It is strong in mechanical spalling resistance, shock resistance and corrosion resistance. This product is widely used in thermal equipments, heating furnace in metallurgical industry, boilers in electricity industry, and building material industry furnace.
