Refractory Castables Order From South African Customers

In December 2022, a South African customer contacted us and said that he had a kiln project and needed 2 tons of refractory castables. After learning that our company provides refractory bricks, insulation bricks and refractory castables, he came to Visited our factory. After seeing our product quality, he said that our quality can meet his needs, and then told us that the order may be placed later, and finally placed the order in February this year, and the customer has received our refractory castable , and gave good reviews. Looking forward to the next cooperation with this customer, we will thank old customers for their support with the best service and best quality!



Refractory castable is a mixture composed of refractory aggregate, powder and binder. After adding water or other liquids, it is suitable for pouring and vibration construction. It can also be prefabricated into prefabricated parts with specified shapes and sizes for construction. Industrial furnace lining. In order to improve the physical and chemical properties and construction performance of refractory castables, an appropriate amount of admixtures is often added, such as plasticizers, dispersants, coagulation accelerators, retarders, expansion agents, degumming-gelling agents, etc. In addition, for refractory castables used in parts subject to large mechanical forces or strong thermal shocks, if an appropriate amount of stainless steel fibers are added, the toughness of the material will be significantly increased. In heat-insulating refractory castables, if inorganic fibers are added, it can not only enhance the toughness, but also help to improve its heat-insulation performance. Because the basic material composition of refractory castables (such as aggregates and powders, admixtures, binders, and admixtures), the setting and hardening process, and construction methods are similar to concrete in civil engineering, it was once called refractory concrete.
