Method for preventing horizontal continuous casting unit copper bush from thermal deformation

The invention discloses a method for preventing a horizontal continuous casting unit copper bush from thermal deformation, and belongs to methods. The technical scheme includes that the method includes the steps of forming a groove one side, close to a furnace body, of water jacket, tightly filling an asbestos cord in the groove, brushing a layer of glass water, fully filling finely-broken furnace manufacturing material between a binding surface of the water jacket and a crystallizer after the water jacket and a graphite plate are mounted, and then compacting. The method for preventing the horizontal continuous casting unit copper bush from thermal deformation has the advantages of avoiding and reducing copper bush surface deformation caused by thermodynamic activity, decreasing copper bush trimming times, effectively guaranteeing close fit between the copper bush and the graphite plate, and the like, and has good popularization and application value.
