Key Points for Selecting the Bulk Density of Lightweight Refractory Castables
Insulating refractory castables—also known as lightweight refractory castables, thermal-insulating refractory castables, or simply insulating castables—are hydraulic, unshaped insulating materials. They are formulated by dry-mixing lightweight insulating aggregates as the primary component with refractory powders, binders, and additives in optimal proportions. Characterized by low bulk density, low thermal conductivity, and superior thermal insulation performance, they are … Read more
