Vacuum smelting furnace

Abstract

The invention relates to a vacuum smelting furnace which comprises a furnace body, a furnace cover, a furnace pipe, a heating device, a vacuum generator and a feeding box. The furnace cover is arranged at the upper end of the furnace body, the furnace cover and the furnace body can be combined in a sealing mode, the furnace pipe is arranged in the furnace body, a furnace cavity is formed in the furnace pipe, the heating device surrounds and is tightly attached to the furnace pipe, the feeding box is arranged on one side of the furnace body, the vacuum generator is arranged at the upper end of the furnace cover, and the vacuum generator is communicated with the furnace cavity through a guide pipe. Compared with the prior art, the vacuum smelting furnace is simple in structure, convenient to feed and discharge, and capable of preheating raw materials to be smelted, and reduces energy consumption.

Description

technical field [0001] The invention relates to the technical field of smelting equipment, in particular to a vacuum smelting furnace. Background technique [0002] Alloy wire needs to be heat treated during the production process. As people's requirements for alloy wire become higher and higher, alloy wire with higher purity appears in people's field of vision, and the purity of some alloys of alloy wire increases. Heat treatment in traditional heat treatment equipment is prone to problems such as oxidation or combustion, which has a great impact on the quality of alloy wire products; [0003] The existing published literature: "Vacuum Smelting Furnace" with application number 201320206930.3 has the following deficiencies: 1. It is inconvenient to feed and discharge materials; 2. High energy consumption. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a vacuum smelting furnace with simple structure, convenient ...
