Abstract

The invention discloses a rapid cooling device for a welding electrode and a using method thereof.The device comprises a drainage pipe, an air inlet pipeline and an air exhaust pipeline, wherein the two ends of the air inlet pipeline communicate with the drainage pipe and a furnace body correspondingly, the two ends of the air exhaust pipeline communicate with the furnace body and the tail end of the drainage pipe correspondingly, and the drainage pipe comprises a contraction section and an expansion section; the expansion section is provided with a heat exchanger, and the front end of the drainage pipe is provided with a conical nozzle. The device can effectively solve the problem that an existing cooling device is long in cooling time.

Description

technical field [0001] The invention belongs to the technical field of cooling devices, and in particular relates to a rapid cooling device and cooling method for welding electrodes. Background technique [0002] Vacuum consumable arc melting is the most important production method for titanium alloy melting at home and abroad. Because titanium reacts with O and N in the air under high temperature conditions, the melting and cooling process of titanium and titanium alloys must be isolated from the air. At present, vacuum welding is mostly used for high-end titanium and titanium alloy electrodes. After welding, vacuum and argon are used for cooling. After the electrode temperature is lower than 300°C, the furnace is opened to check and clean the welding scars. Usually, the vacuum cooling time is longer than 2 hours, and the argon cooling time is longer than 1 hour, so as to ensure that the electrode does not react with air and change color after the furnace is opened. This co...
