High alumina refractory castable mainly include high aluminum, mullite and corundom refractory castable. This series of products are featured with great strength, anti-scouring, wear resistance and excellent performance. In addition, we can produce the material into a fast sintering explosion proof castable saper the sintering time required by the user.
Castable refractories is product that is used in various part of furnace as Monolithic Refractories that added hydraulic alumina cement to refractory aggregate.Our company is producing suitable product to installation and working condition through a quality control,this product which is minimizing alumina cement for using various dispersants and ultra fine powder so it has excellent abrasion resistance,erosion resistance,spalling resistance and chemical resistance.It widely used in part of various industrial furnace including incinerator,nonferrous metal furnace etc.

Application industry:
Iron And Steel Industry
Refractory material is an important material used in the steel industry. It is mainly used in the lining of steelmaking furnaces, ironmaking furnaces, bearing and transporting ladles of ladles for slag and slag, As well as the lining of the flue and blast furnace body that conducts the heat. So, simply, we can think of it as a structural material.
Glass Idustry
Refractory material is the main building material of glass melting furnace, which has the decisive influence on glass quality, energy consumption and even product cost. The development of glass melting technology relies heavily on the progress and quality improvement of refractory manufacturing technology.
