Compared with prior art, the utility model has the advantages and positive effects that：
Large-scale roller Bead weld repair workbench of the present utility model, before built-up welding, by the upper furnace body and lower furnace body of heating furnace point
Open, axle journal guard circle is installed on workpiece, by work piece hoisting to turning rolls（Workpiece roll is enable on wheel carrier by transmission
It is continuous to rotate）；Separate body of heater is closed and fixed again, and the main body of roll is closed in burner hearth.It is required that body of heater two ends through hole with
Gap between roll neck is as far as possible small（About 5mm）, to improve the sealing of burner hearth, it is powered slow to roll preheating.
During built-up welding, lower volume both sides heat roll body with adding thermal resistance by being powered.When reaching welding temperature, by upper furnace body
Hang down, welding head implements built-up welding to roll.In weld deposit process, lower volume is powered to ensureing the interlayer temperature of roll overlaying all the time
Degree.Interlayer is heat-treated or the method for finished heat treatment is identical with preheating, and heat treatment process is set as requested.Finished heat treatment knot
Roll slow cooling is to room temperature after beam.Upper furnace body is hung down, is processed on lifting roll to lathe, whole Bead weld repair processes terminate.
Large-scale roller Bead weld repair workbench of the present utility model, once completes preheating, built-up welding, heat on repair platform
Handling process, it is to avoid the defect more than all swivel links, repairing efficiency is short, built-up welding operation is few, remediation efficiency is high.
