Abstract
The invention belongs to the technical field of smelting equipment, and discloses a vacuum efficient integrated copper crucible applied to an electric arc smelting furnace in order to solve the technical problems that in the prior art, equipment is poor in water leakage performance and air tightness and low in vacuumizing speed. A suction casting crucible is arranged in the center of the top end of the crucible body, smelting crucibles are arranged on the periphery of the suction casting crucible, and the bottom of the suction casting crucible extends downwards in an integrated mode to form a mold cavity; a cooling water passage is arranged at the bottom end of the crucible body, and the cooling water passage is coaxially arranged to form an annular labyrinth structure by taking the outer wall of the mold cavity as the center; and the outer side wall of the bottom end of the mold cavity protrudes outwards to form a connecting bottom, the bottom end of the crucible body is connected with a copper cap through the connecting bottom, and melt is collected through the copper cap. Good water tightness can be ensured, and a good heat dissipation effect is achieved; the air tightness is improved, the vacuumizing speed is greatly increased, and the time is saved for scientific researchers.
Description
technical field [0001] The invention belongs to the technical field of smelting equipment, and in particular relates to a vacuum high-efficiency integrated copper crucible applied to an electric arc smelting furnace. Background technique [0002] Vacuum electric arc furnace is a special equipment for smelting metals. It is a metallurgical process in which metal materials and other auxiliary materials are put into the furnace to be melted and tempered. The materials in the high-temperature furnace undergo certain physical and chemical changes to produce crude metals or alloys. The smelting crucible is a container for smelting physical and chemical reactions. [0003] There are three problems in the equipment in the prior art: firstly, on the original instrument, the crucible and the sleeve are not integrated, but are connected by threads, which leads to the disassembly of the sleeve and the crucible every time. Dirt, dust, affects the overall airtightness and reduces the rat...
