粘土质隔热耐火砖
Application Summary AI generated
This standard specifies the classification, technical requirements, test methods, and inspection rules for insulating fireclay refractory bricks used in thermal equipment. It is applied in industries such as metallurgy, ceramics, and glass manufacturing, where these bricks serve as lightweight insulation linings in kilns, furnaces, and other high-temperature structures to reduce heat loss and improve energy efficiency. The standard ensures consistent quality for applications requiring thermal insulation up to 1400°C, particularly in non-load-bearing or low-load environments.
