Description

Technical Field

[0001] The embodiments of this utility model relate to a device for removing a crucible from a vacuum self-consuming solidification furnace, specifically a device for removing a solidification furnace crucible. Background Technology

[0002] A vacuum arc remelting furnace is a specialized piece of equipment used for melting titanium and titanium alloys, as well as reactive refractory metals. It uses a consumable electrode as the negative electrode and a water-cooled copper crucible as the positive electrode. The heat of the electric arc melts the electrode, keeping the surface of the molten pool liquid while the bottom and surrounding areas are forcibly cooled by water, resulting in a bottom-up crystallization process. The electrode is continuously lowered at an appropriate rate to maintain the arc melting process, while the molten liquid solidifies into a thin "shell" on the crucible wall. Melting stops when the required casting volume is reached, the crucible is inverted, and the molten liquid is poured into a pouring cup and then into a mold to form a casting. After the casting cools to a suitable temperature, it is removed from the furnace, and on-site operators clean the crucible and pouring cup. Currently, domestic vacuum arc remelting furnaces are designed with the crucible and pouring cup fixed inside the furnace, requiring on-site operators to enter the furnace to remove the solidified shell and splashes. Due to the poor environment and limited space inside the furnace, operation is extremely difficult and poses safety hazards. Utility Model Content
