Low cement series refractory castable

Description

Low cement series refractory castable refers to the calcium aluminate cement added less than 8% of the castable refractory. The CaO content in the castable is less than 2.5%.Its main products are low cement, ultra-low cement and cement-free refractory castable, with high density, low porosity, high strength, low wear, heat shock and erosion resistance and other characteristics, but also has a strong volume stability and construction water consumption Low profile.According to its material varieties, can be divided into aluminum silicate, mullite quality, corundum, magnesium aluminum, spinel, carbon and silicon carbide and other low-cement series of castables. According to its use, can be divided into blast furnace iron trench refractory castable and steel ladle refractory castable.
High temperature resistance, erosion resistance, peeling resistance, thermal shock stability
Applicable to large cement kiln decomposition furnace, kiln door cover, rising flue, grate cooler, and other high temperature, alkali corrosion serious parts.

Features &Advantages:
1) The low calcium oxide content in the castable can reduce the eutectic phase in the material, thus improving the refractoriness, high temperature strength and slag resistance.
2) The number of cement hydrates produced after molding curing is small, and there is no problem that the intermediate temperature strength is decreased when there is no large amount of hydration bond in the heating and baking, but gradually sintered with the increase of heat treatment temperature.
3) The water demand of the castable material is greatly reduced, so the porosity is low and the bulk density is high.

Application of low cement castable:

Mainly used in metallurgy, power, petroleum, chemical and various silicate kilns, such as furnace refining equipment, some components, furnace refining bag cover, electric furnace furnace top lining, heating furnace soaking furnace lining Stove lining, tundish lining, tapping tank, high temperature burner and blast furnace trench cover, ladle lining and so on.
