Ultra Low Cement Refractory Castable Has Superior Strength

Ultra Low Cement Castable

Ultra low cement castable is a kind of monolithic refractory castable which can service at the temperature of over 1550℃ in Rongsheng refractory. 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.

Description of Ultra Low Cement Castable

Ultra low cement castable is a refractory with sound performance which has both general advantages of refractory castable and its special strength. With the replacement of superfine powder to part of cement binder, this castable’s performance has been improved greatly. It is wear-resistant which is for the reason of little amount of cement. And also, with the increasing of temperature, its strength  can get improved, which is good for its service under high temperature.

As we all know, the development trend of refractory is decreasing the amount of cement. Therefore, the ultra low cement castable is getting popular in refractory castable field for its superior strength. For instance, 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.
