Embodiment
As shown in Figure 1, a kind of pipe material inner wall bright annealing device, is integrally provided on base support 1; Base support 1 upper end is provided with workpiece lumen 15, and outer being provided with successively according to workpiece motion s direction of workpiece lumen 15 is given inflatable air chamber 13, induction heating gas guarantor room and graphite water jacket gas guarantor's cooling room 9 and fixed by support 16; Base support 1 lower end is provided with intermediate frequency transformer 4; Wherein, fixedly give on support 16 that plenum chamber 15 and induction heating gas protects room and be respectively equipped with the first protection gas import 11 and the second protection gas import 12.
Described induction heating gas is protected room and is made up of silica tube 6, ruhmkorff coil 8 and atmosphere protection air chamber 7; it is characterized in that: outside silica tube 6, be provided with atmosphere protection air chamber 7; be wound with ruhmkorff coil 8 outside atmosphere protection air chamber 7, its ruhmkorff coil 8 connects intermediate frequency transformer 4 by high-tension cable 3.
Described graphite water jacket gas is protected cooling room and is made up of carbon tube 9 and atmosphere protection air chamber 7, it is characterized in that: atmosphere protection air chamber 7 is arranged on outside carbon tube 9.
The first ventilating joint 2 and the second ventilating joint 5 is provided with in described workpiece lumen 15.
Described intermediate frequency transformer 4 connects intermediate frequency induction heating device 14 and obtains power supply energy.
Working process: give plenum chamber 7 when one end of workpiece enters, shielding gas has been entered by the first protection gas import 11 and has given plenum chamber 7 will to give air in plenum chamber 7 emptying before this, give plenum chamber 7 and be full of shielding gas, shielding gas enters workpiece lumen 15 by the first ventilating joint 2, due to the relation of pressure difference, workpiece lumen 15 air protected gas progressively disperses in air, and workpiece lumen 15 is full of shielding gas; Induction heating light solution annealing operation is carried out along with workpiece moves forward to induction heating gas guarantor room, now, shielding gas continues to be entered by the first protection gas import 11 and be full of whole induction heating gas to protect room, graphite water jacket cooling atmosphere protection indoor enter workpiece lumen 15 by the second ventilating joint 2, the protection gas carrying out supplementary workpiece lumen 15 scatters and disappears, guarantee that workpiece lumen 15 is full of shielding gas all the time in whole annealing process, guarantee the annealing quality of workpiece; Along with the continuation of workpiece moves forward; whole is among atmosphere protection by workpiece two ends; along with workpiece movable; the outlet being protected room by cold gas enters among air by its second ventilating joint 5; when it enters air, because its port is identical with air, have shielding gas loss unavoidably; now shielding gas enters the loss that workpiece lumen 15 carrys out supplementary shielding gas, until workpiece all completes bright solution annealing through the first ventilating joint 2 being still in graphite water jacket cold gas guarantor room.
