A kind of copper and copper alloy high-efficiency melting and casting method

Abstract

The invention relates to the technical field of melting and casting, in particular to a high-efficiency melting and casting method for copper and copper alloys. The melting equipment used in the method includes a shell, an auxiliary structure, a feeding structure, a smoke exhaust structure, an air intake structure, and a melting furnace body , a partition structure and an insulation layer, the shell for providing protection and insulation is connected to the body of the smelting furnace for melting copper and copper alloys; the flue gas produced by burning the coal fuel in the combustion chamber through the smoke exhaust structure Sufficient and rapid discharge, so that the coal fuel can be fully and quickly burned, so that the partition structure can fully and quickly absorb heat, and improve the melting efficiency of copper inside the smelting chamber. Oxygen intake, so that oxygen can fully contact with coal fuel, so that coal fuel can be fully burned while oxygen is consumed quickly, improve the utilization rate of coal, reduce the amount of oxygen that is discharged together with flue gas, and make flue gas fully while avoiding oxygen waste was quickly expelled.

Description

technical field [0001] The invention relates to the technical field of melting and casting, in particular to a high-efficiency melting and casting method for copper and copper alloys. Background technique [0002] Copper alloy is an alloy composed of pure copper as the base and adding one or several other elements. Pure copper is purple-red, also known as red copper. It has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. It is mainly used to make power generation. Electrical equipment such as machines, busbars, cables, switchgear, transformers, heat exchangers, pipes, and flat collectors for solar heating devices. Commonly used copper alloys are divided into three categories: brass, bronze, and white copper. Copper alloy casting is to melt copper and copper alloy raw materials at high temperature, and then directly cast them into products.

AI Technical Summary

Problems solved by technology

[0003] When traditional copper and copper alloys are melted and cast, coal is added inside the melting furnace as a raw material for combustion to melt copper and copper alloys at high temperature. When a large amount of coal is added inside the melting furnace, a large amount of oxygen needs to be added inside the melting furnace for coal combustion. However, when the flue gas is not burned, it is easy to emit oxygen together, which will cause a waste of oxygen and reduce the combustion efficiency of coal
