Abstract

The invention discloses a method for annealing a plate by using a coiled material vertical vacuum annealing furnace. Plates; 3. Put the plates in the first material tray of the special tooling and reserve a middle position, and then cover the lining boards and briquetting blocks; 4. Complete the loading according to the loading process in step 3, and place the temperature measuring workpiece evenly They are respectively installed in the middle of each plate layer; 5. Design the vacuum annealing process and input it into the operation control system for execution; 6. Set the heating rate and adjust the output power to complete the vacuum annealing. The present invention designs the special tooling for the coiled material vertical vacuum annealing furnace, combines the improvement of the furnace loading method and the adjustment of the heating parameters, loads the plate in the vertical space, and makes the heat evenly transferred to the plate, and improves the uniform annealing temperature of different layers of plates It realizes the annealing of the plate in the coil vertical vacuum annealing furnace.

Description

technical field [0001] The invention belongs to the technical field of metal material processing, and in particular relates to a method for annealing a plate by using a coiled material vertical vacuum annealing furnace. Background technique [0002] Zirconium alloys are widely used in the nuclear industry due to their low thermal neutron absorption cross section, good corrosion resistance to high temperature water and superheated steam, and good mechanical properties. Zirconium alloy plates used in the nuclear industry have extremely high requirements on their corrosion and other properties, and vacuum annealing is the key to determine the performance of zirconium alloy plates. [0003] The plate horizontal vacuum annealing furnace (hereinafter referred to as "horizontal furnace") adopts a flat charging method, and its heating method is longitudinal heat radiation and heat conduction; while the coil vertical vacuum annealing furnace (hereinafter referred to as "vertical furn...
