Ultra low cement castable is a kind of monolithic refractory castable which can service at the temperature of over 1550℃. It mainly consists of refractory aggregate, powder and aluminate cement as its binder, in which the amount of cement is less than 1.0%. Due to low amount of CaO, this castable material has high refractory temperature, high strength under high temperature and good slag-resistance performance. In addition, ultra low cement castable refractory has low porosity, high bulk density.
Ultra low cement castable is widely used in metallurgical industry, petrochemical industry, power plant, construction field and other industries. It has many types, which means it can be used on different parts of the kilns and furnaces. For instance, ultra low cement high alumina chrome castable can be used on the slide and platform of the heating furnace.
The ultra low cement castable is getting popular in refractory castable field for its superior strength. The sinter zone of the cement rotary kiln usually uses ultra low cement castable which can not only suit for all kinds of shapes but also withstand the high temperature, scouring and slag-erosion.
