Abstract

The invention provides a vacuum vertical continuous casting machine for high-temperature metal and alloy. The continuous casting machine comprises a vacuum device, a smelting device, a heat preservation device, a crystallization forming device and a traction device. The vacuum device comprises a furnace body and an upper cover body, wherein an exhaust valve and an air inlet valve are arranged on the furnace body; the smelting device comprises a crucible, wherein the crucible is arranged in the furnace body, a heating coil is arranged on the periphery of the crucible, a stirring motor is arranged on the upper cover body, an output shaft of the stirring motor is connected with a stirring rod, and the lower end part of the stirring rod is connected with a stirrer; a discharge hole is formed in the lower part of the crucible; the crystallization forming device comprises a crystallizer, coolers and a heater, the crystallizer is arranged in the peripheral direction of a discharging port in the lower portion of the crucible, and the coolers are arranged on the periphery of the crystallizer; a heater is arranged at the periphery of the cooler; the traction device comprises traction wheels which are arranged in pairs.

Description

technical field [0001] The invention belongs to the technical field of metal continuous casting, and in particular relates to a vacuum vertical continuous casting machine for high-temperature metals and alloys. Background technique [0002] With the rapid development of aerospace, military industry, nuclear industry, smart factories and other fields, there is an increasing demand for high-temperature metal and alloy wires (materials with melting points between 1600°C and 2200°C). In addition to complex and uniform multi-components, high-temperature metal and alloy wires also need to have a stable structure, which puts forward higher requirements for wire blanks. Uneven control of the composition of the wire billet, many casting defects, uneven structure, and severe segregation directly lead to wire breakage during wire processing, and the mechanical properties (strength, elongation, etc.) and electrical properties of the wire are unstable, and it is impossible to obtain a ce...
