Preparation process of copper-zinc alloy waste energy-saving smelting recycled copper rod

Abstract

The invention discloses an energy-saving preparation process for smelting a recycled copper rod by copper-zinc alloy wastes, relating to the technical field of manufacturing of brass rods. The energy-saving preparation process is characterized by comprising the following steps of (1) putting the copper-zinc alloy wastes into a crusher for crushing; (2) putting crushed fragments into an electrolytic tank for wet separation to obtain a pure copper-zinc alloy; (3) detecting copper and zinc components in the copper-zinc alloy obtained in step 2 respectively; (4) mixing the copper and zinc components in the copper-zinc alloy; (5) smelting the mixed copper-zinc alloy at high temperature by using a smelting furnace; (6) carrying out extrusion molding on the smelted copper-zinc alloy by using an extruding machine to form a copper rod; (7) grinding the surface of the copper rod. The energy-saving preparation process is convenient and quick, thorough in recycling, environment-friendly, energy-saving and low in cost for manufacturing of brass rods.

Description

Technical field: [0001] The invention relates to the technical field of brass rod manufacturing, in particular to a preparation process for copper-zinc alloy waste energy-saving smelting regenerated copper rods. Background technique: [0002] It is a memory alloy. Golden yellow, gold-like color, commonly known as brass. Brass rods are rod-shaped objects made of copper and zinc alloys. Brass rods have good mechanical properties and wear resistance, and can be used to manufacture precision instruments, motors and other equipment. Because the price of zinc is relatively lower than that of copper, in many devices, brass is used to replace pure copper rods, so that the requirements of the equipment can be met, and the price of the equipment can be effectively reduced. In the prior art , The raw materials of brass rods are mixed with pure copper and zinc, and copper-zinc alloys cannot be extracted from copper-zinc alloy scraps to make them directly, resulting in higher productio...

Because the price of zinc is relatively lower than that of copper, in many devices, brass is used to replace pure copper rods, so that the requirements of the equipment can be met, and the price of the equipment can be effectively reduced. In the prior art , the raw materials of brass rods are mixed with pure copper and zinc, and copper-zinc alloys cannot be extracted directly from copper-zinc alloy waste, resulting in higher production costs for brass rods
