Product Details

China Factory Wholesale Fire Low Cement high alumina Castable

Standard / Medium Cement castables with high alumina cement can be used within temperatures from 1300oC up to 1800oC. They have good thermal shocks, good mechanical and chemical resistances such as for abrasion, chemical corrosion and physical wear.

Process conditions, time available for the repairs, accessibility, qualified applicators / efficient equipments (gunning machine, shot crating pumps,..) and costs are the key factors that will allow you to decide between different techniques of applications and families of castables.

These types of refractory castables are with lower cement contents. Other additives and a higher proportion of high value raw materials are included in order to ensure better physical properties, including lower porosity, good abrasion and higher mechanical resistances.

Qualified applicators and a rigorous control are required during their application.

They exist in gunning versions and for some of them in self-flow versions, which does not need vibration and a full demolition of the surfaces to be repaired.
