Refractory castable composition and application

The degree of refractoriness refers to the refractory castable cone sample that counteracts the high temperature effect without softening the melted temperature in the absence of load. The refractory castables are accompanied by high temperature skills, which originated in the middle of the Bronze Age. In the Eastern Han Dynasty of China, clay refractory castables have been used as kiln and enamel for burning porcelain.
