Preparation process of wear-resistant and refractory castables:
Ingredients: Select appropriate refractory aggregates, powders, additives, and binders according to the required properties, and proportion them in a certain proportion.
Mixing: Mix the prepared ingredients to ensure that the various ingredients are evenly distributed.
Pouring: Pour the mixed castable into the prepared mold and vibrate or compact it to ensure that the castable fills the mold and expels air bubbles.
Hardening: Place the poured refractory castable in an appropriate environment for hardening. Hardening times and temperatures will vary depending on the specific bond.
Demoulding: After waiting for the refractory castable to harden, demould it from the mold. At this time, the refractory castable has been initially formed.
Drying and Curing: The castables after demoulding need to be dried and cured. This process usually requires placing it in a constant temperature and humidity environment so that it gradually loses moisture and increases strength. The length of drying and curing time depends on the specific binder and environmental conditions.
Heat Treatment: To make the refractory castable have better high-temperature resistance, it needs to be heat treated. This usually involves heating and holding at a certain temperature. The heat treatment temperature and time will vary depending on the composition and requirements of the castable.
