Abstract

The invention relates to a vertical guide type vacuum melting inert gas shielding continuous feeding continuous casting machine. A vacuum chamber I is connected with a vacuum chamber II by a gate valve; a vacuum chamber III is connected with the vacuum chamber II in a sealing way; a ventage is formed in the vacuum chamber II; a crucible is located in the vacuum chamber II; a heating coil is located outside the vacuum chamber II; a stirring device can be inserted into the crucible by passing through the vacuum chamber II; a crystallizer is connected with a liquid flowing opening of the crucible and a high-density heat insulation pad is arranged between the crucible and a cooling mechanism of the crystallizer; a metal rod cooling device is arranged on a metal rod outlet below the vacuum chamber III; a dummy bar is in contact with the bottom of the crucible; a traction device is connected to the dummy bar. According to the vertical guide type vacuum melting inert gas shielding continuous feeding continuous casting machine, the continuous feeding can be realized, metal can be molten and stirred under high vacuum degree, the continuous casting can be realized according to a setting speed under inert gas shielding, and a metal rod with a columnar crystal structure and infinite length can be obtained.

Description

technical field [0001] The invention belongs to the technical field of physical metallurgy and relates to a continuous casting machine, in particular to a vertical-drawing vacuum melting inert gas protection continuous feeding continuous casting machine. Background technique [0002] With the wide application of metal and alloy wires in the fields of electronics, automobiles, and data transmission, the wires are required to be thinner in diameter (less than 0.02mm in diameter), longer in length, and have a consistent organizational structure and uniform components. Wire blanks place higher demands. Insufficient wire blank structure length, inconsistent structure, uneven composition, etc. directly lead to wire breakage during wire processing and unstable mechanical properties (strength, elongation, etc.) and electrical properties of the wire, which seriously affects the metal and alloy wire. Applications in the fields of electronics, automobiles and data transmission. Impro...
