Abstract

The invention belongs to the technical field of electric arc melting furnace equipment, and aims to provide a vacuum efficient electric arc melting furnace system aiming at the technical problem of poor air tightness in the prior art. The vacuum efficient electric arc melting furnace system comprises an argon tank, an electric arc furnace, a diffusion pump and a vacuum pump, wherein the argon tank is connected with the electric arc furnace through a gas pipeline, and the electric arc furnace is filled with argon through the argon tank; the top end of the electric arc furnace is connected with a rocker through a rocker base, the bottom end of the electric arc furnace is connected with a copper cap through a crucible, the side of the electric arc furnace is connected with a diffusion pump through a pipeline, the electric arc furnace is connected with a vacuum pump through a gas pipeline, and the vacuum pump is started to control the electric arc furnace to vacuumize. Airtightness of the system is improved. According to the design of the comprehensive system provided by the invention, the high-vacuum air exhaust time of the smelting furnace is improved from 30 minutes every time to 1 minute every time. The time of scientific researchers is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of electric arc melting furnace equipment, and in particular relates to a vacuum high-efficiency electric arc melting furnace system. 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] The technical problems existing in the equipment in the prior art are as follows: 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 and dust will be generated, which will affect the ov...
