How to correctly select lightweight aggregate for high performance lightweight castables

Lightweight castables are mainly used in the safety lining of various melting furnaces or the lining of atmosphere furnaces in metallurgical and petrochemical industries. Traditional lightweight castables have the problems of high-temperature shrinkage, low strength, insufficient heat-insulating properties, and low service temperature, which limit their use and make them even more difficult to meet the
