Problems solved by technology

The preparation process of copper and alloys is mainly continuous casting first, and then formed by hot extrusion or continuous extrusion, which requires two sets of equipment. The metal after casting needs to be cooled, rolled, and transported. Many intermediate processes such as feeding, preheating, and refueling are also required, with a long process and low efficiency

Abstract

The invention provides a device for continuously casting and extruding copper and copper alloy. The device comprises a vacuum induction melting furnace, a runner and a continuous casting and extruding machine which are communicated in sequence, an inert gas inlet is formed in the top of the vacuum induction melting furnace; an inert gas inlet is formed in the side wall of the runner; an extrusion wheel airtight cover is arranged in the continuous casting and extruding machine; the extrusion wheel airtight cover is connected with a shoe seat and a deformable body in the continuous casting and extruding machine to seal a casting and extruding space; and an inert gas inlet is formed in the side wall of the extrusion wheel airtight cover. The inert gas inlet is formed in the top of the vacuum induction melting furnace, it can be guaranteed that copper and copper alloy are smelted in the vacuum and inert gas environment, and the problems of oxidation and volatilization are avoided; the inert gas inlets are formed in the side wall of the runner and the side wall of the extrusion wheel airtight cover of the continuous casting and extruding machine, so that the alloy melt can be prevented from being oxidized before entering the continuous casting and extruding machine and during continuous casting and extruding in the continuous casting and extruding machine, and continuous casting and extruding forming of copper and copper alloy is achieved.

Description

technical field [0001] The invention belongs to the technical field of continuous casting and extrusion, and in particular relates to a device and method for continuous casting and extrusion of copper and copper alloys. Background technique [0002] Continuous casting and extrusion molding is to use liquid metal as a blank to directly enter the extrusion cavity formed by the extrusion wheel and the fixed shoe block, so that the metal is deformed in the cavity, and the die hole is extruded into a material, forming a new type of casting and extrusion. extrusion technology. [0003] At present, continuous casting and extrusion are mainly used in low melting point alloys such as aluminum, magnesium and other alloys. Due to the high melting point of copper and copper alloys, they are easy to oxidize, and the added alloy elements are volatile and other problems limit the application of continuous casting and extrusion technology of copper and copper alloys. . The preparation pro...
