Problems solved by technology

When the current electrode rod conducts electricity, it is a copper rod that conducts electricity and is pneumatically clamped. This structure conducts unevenly and is prone to arc deviation. When the gas is cut off, the titanium ingot is easy to fall off, causing a safety hazard in smelting.

Abstract

The invention discloses a gravity clamping electricity conducting device for a skull furnace, and belongs to the technical field of smelting equipment. The gravity clamping electricity conducting device comprises a cylinder component, an electrode stem component, a steel ball component and a sealing component. The gravity clamping electricity conducting device is special for the ingot clamping and the smelting electric conduction of the skull furnace; as a pull rod in an electrode steam is fixed with a servo motor in an equipment body, and electrode stem solder mask is connected with the pull rod through sealing and insulation devices, the electrode stem solder mask can realize vertical movement in a small range through self weight and a pneumatic device to achieve the clamping by self-gravity after the ingot clamping; when the pneumatic system is inflated, the clamped ingot is loosened; and the electrode stem solder mark transmits current onto a titanium ingot in electrification to realize the smelting process. The gravity clamping electricity conducting device is compact in structure, easy to operate, high in adjustment precision and efficiency, safe and reliable.

Description

technical field [0001] The invention relates to a gravity clamping conductive device used in a shell coagulation furnace, which belongs to the technical field of smelting equipment. Background technique [0002] Titanium and its alloys have the remarkable characteristics of light specific gravity, high specific strength, and good corrosion resistance. In recent years, they have been widely used in various fields such as aerospace, chemical industry, shipbuilding, and civil use. The chemical properties of titanium and its alloys are very active, and they are easily oxidized and polluted by contact in the high-temperature molten state. Therefore, when making complex titanium mechanical parts and thin-walled parts, vacuum consumable electrode shell furnace equipment is often used for casting. Vacuum consumable electrode shell solidification furnace is a special equipment for obtaining titanium and its alloy castings. In order to ensure low voltage and high current when it work...
