Refractory cement is a kind of castable refractory which refractory temperature is about 1580℃. It is also called aluminate cement. In the refractory cement composition, calcium aluminate takes the main part, and the amount of alumina is about 50%. With CaO•Al2O3, alumina, and 2CaO•SiO2 as its main mineral material, aluminate cement usually take a color of yellow, brown and gray.
Refractory cement can be used to cementing all kinds of refractory aggregate, made into refractory mortar and concrete. Due to its wide application, refractory cement can be used in metallurgy, petroleum, construction and other industries.
Description of Refractory Cement
Refractory cement is refractory castable which is usually used as binder in unshaped refractory materials. It is mainly used to made refractory concrete. For its history, developed from last century, refractory cement material has experienced a long period in promoting its performance. Nowadays, it is a kind of refractory with high quality and a series of sound performance. Specifically, refractory cement can withstand high temperature, serve in the harsh condition of abrasion, shock and heating and so on.
It has high strength in the early period, frost-resistance, anti-resistance and shock-resistance. With these good performance, refractory cement is widely used in steel industry, petroleum industry, power industry, building industry, and it also can used in water treatment. Mixed with high alumina powder, high alumina aggregate and additives, it can be used in high temperature kiln and furnace project.
Refractory Cement Manufacturing Processing
Refractory cement is hydraulic contentious material. It takes several steps to get this refractory. First, take bauxite and limestone as the material and then sinter them into clinker. At last, grind the clinker into powder.
Types of High Temperature Refractory Cement
According to its composition, refractory cement can be divided into aluminate refractory cement, low calcium aluminate refractory cement, calcium magnesium aluminate cement and dolomite refractory cement.
