Abstract

The invention discloses an ultrahigh-temperature vacuum induction melting furnace, and relates to the technical field of vacuum melting. The ultrahigh-temperature vacuum induction melting furnace comprises a control system and a furnace body and a furnace cover. The furnace body and the furnace cover are connected in a sealed mode, an induction melting and crucible heat preservation device is arranged in the furnace body, the outer wall of the furnace cover is connected with a furnace cover lifting device, and the furnace cover lifting device is connected with a hydraulic system. A temperature measuring device is arranged above the furnace cover. One side of the furnace body is communicated with a vacuum system, the other side of the furnace body is provided with a power inlet device, one end of the power inlet device is connected with a medium-frequency power supply, and the other end is connected with an induction coil of the induction melting and crucible heat preservation device. The furnace body, the furnace cover, the temperature measuring device, the hydraulic system, the induction melting and crucible heat preservation device and the medium-frequency power supply are respectively communicated with a water cooling system through pipelines, and the furnace body is connected with an inflating and deflating system. The control system can electrically control the vacuum system, the hydraulic system, the water cooling system and the induction melting and crucible heat preservation device. According to the ultrahigh-temperature vacuum induction melting furnace, the smelting of a high-temperature material with a smelting melting point of 3200 DEG C or below can be satisfied.

Description

technical field [0001] The invention relates to the technical field of vacuum smelting, in particular to an ultra-high temperature vacuum induction melting furnace. Background technique [0002] Vacuum induction melting produces eddy currents during the electromagnetic induction process, which melts the metal. This process can be used to extract high-purity metals and alloys. It mainly includes vacuum induction furnace melting, suspension melting and cold crucible melting. Because smelting under vacuum is easy to remove nitrogen, hydrogen, oxygen and carbon dissolved in steel and alloys to a level much lower than smelting under normal pressure, and at the same time for impurity elements whose vapor pressure is higher than that of the base metal at the smelting temperature ( Copper, zinc, lead, antimony, bismuth, tin and arsenic, etc.) can be removed by volatilization, and the components of active elements such as aluminum, titanium, boron and zirconium that need to be adde...
