Refractory castables refer to a mixture composed of refractory aggregates, binders, and admixtures, which are mixed with water (or liquid binder) to form mud that can be constructed by pouring. The difference from other unshaped refractory materials is that refractory castables have a certain setting and hardening time after construction. Therefore, after casting and molding, they need to undergo a certain period of curing before they can be demoulded and then can be put into baking after an appropriate period of natural curing. Roast and use. The production process of refractory castables is simple, labor-saving, and energy-saving, with high construction efficiency and good quality. It can be prepared on-site or materials with excellent performance can be selected as needed. Therefore, refractory castable is an unshaped refractory material that is used in large quantities and has a wide range of applications in furnace construction projects. 🔥 Hot sale! high alumina refractory casta
