Electrode Drive System of Vacuum Cold Crucible Shell Condensation Furnace

Abstract

The invention belongs to the technical field of vacuum metallurgical equipment, and particularly relates to a vacuum cold crucible skull furnace electrode transmission system. The vacuum cold crucibleskull furnace electrode transmission system is convenient to use and reliable and stable in work. The vacuum cold crucible skull furnace electrode transmission system comprises a walking mechanism, alifting platform, a door type frame, an anti-top rapid lifting mechanism, an electrode rod, a dynamic seal seat, a lifting power unit of the lifting platform and an electrode chamber lifting mechanism. The vacuum cold crucible skull furnace electrode transmission system is structurally characterized in that the door type frame is arranged on the walking mechanism, the lifting platform is arrangedon the door type frame, the anti-top rapid lifting mechanism is arranged on the lifting platform, the power output end of the anti-top rapid lifting mechanism is connected with the upper end of the electrode rod, the dynamic seal seat is arranged above an electrode chamber and corresponds to an upper end opening of the electrode chamber, the lower end of the electrode rod penetrates through the center of the dynamic seal seat, the lifting power unit is arranged on the platform, and the electrode chamber lifting mechanism is arranged on the door type frame.

Description

technical field [0001] The invention belongs to the technical field of vacuum metallurgy equipment, and in particular relates to an electrode transmission system of a vacuum cold crucible solidification shell furnace. Background technique [0002] The electrode transmission system of the vacuum cold crucible condensing furnace uses the melting conditions of the vacuum consumable electrode electric arc furnace, and uses the pre-fabricated consumable electrode (remelting) of the required diameter and length to perform rapid melting in the water-cooled copper crucible , when the predetermined amount of melting is reached, the crucible is tilted, and the liquid titanium is poured into the casting mold fixed on the centrifugal disc (centrifugal casting or static casting), so as to obtain various castings with complete shapes and clear outlines. [0003] The furnace structure of the shell congealing furnace determines the furnace type of the shell congealing furnace. The size of t...

AI Technical Summary

Problems solved by technology

[0006] Whether it is a horizontal furnace or a vertical furnace, for a large-capacity shell furnace, the size of the furnace body is very large, the structural reliability and expandability are very low, and the modal frequency of the centrifugal mechanism is very small due to the large mass of the mold. , so that the vibration of the centrifugal mechanism is very large, and the rigid connection between the centrifugal mechanism and the furnace body causes the vibration to be transmitted to the furnace body, making the vibration of the furnace body and the electrode rod strong and unable to work. Therefore, there is no large-scale shell furnace with a reasonable structure at present.
