NOUFERROUS METALLURGICAL EQUIPMENT

Local spalling of refractory lining at the roof poses a significant hazard for the stability and safety of the 109m² fluidized roaster for Zn smelting. By local protective maintenance, the stability of roof structure is restored, ensuring safe and reliable operation. It solves the technical problem that damaged roof lining was difficult to repair locally in the Zn roaster in a timely manner during service, and provides a method for repairing the roof lining of Zn roaster, which can be widely applied in the industry.
