AI Technical Summary
The high-temperature resistant layer of the settling chamber is prone to cracking, bulging, and collapse in the electric furnace, leading to frequent maintenance, affecting production continuity and increasing economic losses.
The high-temperature resistant layer adopts a segmented frame structure, combined with metal reinforcing ribs and high-alumina cast refractory, and is further reinforced with zirconium-containing heat-insulating fiberboard and refractory brick layer to enhance structural strength and resistance to thermal expansion and contraction.
Extend the service life of the high-temperature resistant layer to more than 1 year, reduce the number of maintenance and costs, ensure continuous production of the electric furnace, and reduce construction risks and labor intensity of workers.
