High alumina refractory castables, also named as high alumina castables, 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”.
Properties of High Alumina Castable
high density
low porosity rate
good hot strength
high refractories
high refractoriness under load
strong mechanical spalling resistance
shock resistance and corrosion resistance
Application of High Alumian Castable
This product is widely used in thermal equipments, heating furnace in metallurgical industry, boilers in electricity industry, and building material industry furnace.
