Double-chamber u-shaped furnace body system for shell solidification furnace

Abstract

The invention relates a double-chamber U-shaped furnace body system for a skull furnace, and belongs to the technical field of vacuum metallurgy equipment. The double-chamber U-shaped furnace body system for the skull furnace is safe, reliable and stable in structure, and the pouring height can be improved. The double-chamber U-shaped furnace body system comprises an upper furnace body and a lowerfurnace body, the lower end of the upper furnace body and the upper end of the lower furnace body are connected, and an electrode chamber is arranged at the upper end of the upper furnace body; the double-chamber U-shaped furnace body system is structurally characterized in that the front end of the upper furnace body is provided with an upper furnace door and an upper furnace door transmission mechanism, the front end of the lower furnace body is provided with a lower furnace door and a lower furnace door transmission mechanism, and a rear furnace door is arranged at the lower rear end of the lower furnace body; the upper furnace body adopts a double-layer water-cooled U-shaped structure and is connected with the lower furnace body; the lower furnace body adopts a local water-cooled U-shaped structure, and the lower furnace body and the ground are fixed; and the electrode chamber and the upper furnace body are connected, and the rear furnace door is hinged on the lower furnace body.

Description

technical field [0001] The invention belongs to the technical field of vacuum metallurgy equipment, and particularly relates to a double-chamber U-shaped furnace body system of a condensing shell furnace. Background technique [0002] The double-chamber U-shaped furnace body system of the condensing shell furnace uses the smelting conditions of the vacuum consumable electrode electric arc furnace, and uses the pre-made consumable electrodes (remelting) of the required diameter and length to conduct rapid heating in a water-cooled copper crucible. After melting, when the predetermined melting amount is reached, the crucible is tilted, and the liquid titanium is poured into the casting mold (centrifugal casting or static casting) fixed on the centrifugal disc, so as to obtain various castings with complete shapes and clear contours. [0003] The furnace body structure form of the condensing shell furnace determines the furnace type of the condensing shell furnace. The size of ...

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.
