Description

Technical Field

[0001] An embodiment of the present utility model relates to an automatic quick-insert device in the field of special smelting technology, and particularly to a water-cooled automatic quick-insert device for the mold crystallizer and bottom water tank of an inert-gas shielded electroslag furnace. Background Art

[0002] The mold crystallizer and the bottom water tank are important components of an inert-gas shielded electroslag furnace. The melting, refining, and ingot casting of metal materials from arc starting to hot topping are all completed in the space between the mold crystallizer and the bottom water tank. During the production process, on-site operators fix the bottom water tank and the mold crystallizer together with bolts on the working platform, then use a traveling crane to lift the mold crystallizer and the bottom water tank to the smelting station. After the lifting is completed, workers enter the pit to complete the connection of the cooling water pipes between the mold crystallizer and the bottom water tank. After the smelting is over, workers also enter the pit to complete the disconnection of the cooling water pipes between the mold crystallizer and the bottom water tank. Therefore, during production preparation, after smelting is over, or in case of unexpected situations during the process, the connection or disconnection of the cooling water inlet and outlet joints between the mold crystallizer and the bottom water tank of the inert-gas shielded electroslag furnace is completed manually by workers entering the pit. The inert gas used in the inert-gas shielded electroslag furnace is colorless and odorless. If it leaks and accumulates in the limited space of the pit, once someone enters, it will cause a major accident of oxygen-deficient asphyxiation and death. Summary of the Utility Model
