Things to Remember When Using Castables and Advantages of Castable Refractories
Castable refractory products are non-metallic materials with physical and chemical properties that allow them to withstand high temperatures and retain their composition. Some of their common application is in furnaces and glasswool insulation. In a high-temperature environment, specific products must withstand such a heavy temperature. That is precisely what castable refractory does. There is no doubt about the vital role that refractory castable plays. But there are a couple of things one needs to remember while using this refractory bed material.
Things to Remember When Using Castable
Castables must always be stored in a cool and dry area. One must ensure that the mixers and tools are free from old castable or any other material that can contaminate the product. Such contamination could affect the strength of the castable mix. Only drinking suitable water should be used to mix castable. The temperature of the mix should be optimal as well. Be careful while mixing castable, like castable refractory cement. Too much mixing generates heat and speeds up the setting time. The forms should be covered with oil or grease to prevent moisture loss.
