There are many varieties of refractory materials with different names and various classification methods. The introduction of refractory castables can be divided into three categories: acidic, neutral and alkaline according to their chemical properties; according to the delivery status, it can be divided into two categories: shaped products and bulk castables. Shaped refractory castable products refer to wet billets, prefabricated blocks and unfired bricks produced by methods such as vibration, ramming, vibration pressure and machine pressing.
This type of unshaped refractory products are generally produced in factories, with regular appearance, stable quality, economical and practical; bulk refractory castables refer to the mixture after mixing and leaving the factory in the form of bags, and adding suitable liquids during on-site construction. Material. The bulk refractory castable has few construction tools and can be shaped arbitrarily, which can meet the needs of different users.
There are generally three classification methods for unshaped refractories:
1. Classify refractory castables according to the type of binder;
2. Classified according to the refractory aggregate species;
3. Classified according to construction method.
