Description

Technical Field

[0002] Waste refractory materials refer to refractory materials that have been replaced due to wear, damage or technological updates during use. These materials usually include various refractory bricks, refractory castables, refractory ceramics, etc. They have high refractory temperatures, good thermal stability and chemical stability, and are therefore widely used in the industrial field. However, the treatment of waste refractory materials is an important environmental issue, and reasonable methods need to be adopted for recycling or treatment.
