With temperatures dropping recently, many construction projects have been affected. While refractory products are generally less affected, today we’ll focus on unshaped refractory castables. We’ve previously discussed precautions for installing refractory castables in winter. Some companies may consider these less important, but in fact, several national standards contain specific regulations regarding the winter installation of […]

Refractory materials actually have different applications in various industries! However, their most common applications are in the following five areas. (I) Steelmaking system The steelmaking system includes equipment such as converters, electric furnaces, off-site refining furnaces, ladles and tundishes. In electric furnaces, dry vibrating materials, prefabricated or cast-in-place furnace covers or furnace cover triangles and

The strength of granular materials in castables is generally higher than the strength of the hardening body of the bonding agent and the bonding strength between the granules, so the room temperature strength of castables actually depends on the strength of the hardening body of the bonding agent. Changes in strength at medium and high

Many customers do not know what properties they need to know when buying refractory bricks, and they are afraid that their questions are not professional enough and they cannot buy the right refractory bricks or other refractory materials. In fact, usually refractory bricks and other refractory materials only need to pay attention to the following

Refractory castables are a type of unshaped refractory materials. They are a mixture of refractory aggregates, binders and admixtures, which can be used for construction after adding water (or liquid binder) and mixing. Refractory castables have a certain coagulation and hardening time after construction. Therefore, after casting and forming, they need to be cured for
