How to classify refractory castables

There are many types of refractory materials with different names and various classification methods. Refractory castables can be divided into three categories according to their chemical properties: acidic, neutral and alkaline; according to the delivery status, they can be divided into two categories: shaped products and bulk castables. Shaped refractory castable products refer to wet blanks, prefabricated blocks and unfired bricks produced by methods such as vibration, ramming, vibration pressurization and machine pressing.

This kind of unshaped refractory material products are generally produced in factories, with regular appearance, stable quality, economical and practical; bulk refractory castables refer to the mixture of which is mixed and shipped in bags, and is mixed with appropriate liquid during on-site construction. Material. Bulk refractory castables have fewer construction machines and can be arbitrarily shaped to meet the needs of different users.

Unshaped refractory materials generally have three classification methods:1, classify refractory castables according to binder types; 2, classified according to refractory aggregate varieties; 3, classified according to construction and production methods. These three classification methods have greater practicability and are commonly used.
