Abstract

The invention discloses a copper-clad steel composite rod and a production method thereof. The copper-clad steel composite rod comprises a steel rod core (1) and an outer pure copper layer (2), wherein the copper rod core (1) is processed to be required specification and size from a Q195-Q235 material in a hot-rolling manner; the outer pure copper layer (2) is manufactured into a thinned-wall tube from T2 purple copper in a cold-drawing manner; the size of the outer pure copper layer (2) is 2-5mm greater than the outer diameter of the steel rod core (1). According to the physical cold-extrusion principle, the outer pure copper layer (2) is concentrically arranged on the outer surface of the steel rod core (1) in an extrusion and covering manner, so that the outer pure copper layer (2) and the steel rod core (1) are in atom combination on an boundary and are formed into the integrated composite rod; the copper-clad steel composite rod is scientific in design, the production process is easy to achieve, the cost of production equipment is relatively low, the use property of pure copper is maintained, the cost is greatly lowered, the pure copper resource is saved, and moreover the mechanical property, particularly the bending resistance, is remarkably improved.

Description

A kind of copper covered steel compound bar and production method thereof
Technical field
The present invention relates to low cost, high performance metallic composite material technical field, be specifically related to a kind of copper covered steel compound bar and production method thereof.
Background technology
In recent years, because the copper resource in worldwide is day by day in short supply, copper valency continues to raise up, and is that the manufacturing industry of primary raw material is subject to extreme shock with copper, whole industry is badly in need of one can keep fine copper metal serviceability, and the raw material that can reduce again production cost replace fine copper.
The fine copper bar that tradition uses, not only the fine copper metals resources of at substantial, adds the cost of giant manufacturer day by day, and due to fine copper plasticity better, slightly also there is larger defect in its mechanical property especially bending resistance.
Summary of the invention
Problem to be solved by this invention is to provide a kind of copper covered steel compound bar and production method thereof, reaches both to save copper metals resources, reduce production cost, can keep again copper metal serviceability, can also significantly improve the free-revving engine of mechanical property especially bending strength.
In order to solve the problem, the technical solution used in the present invention is: a kind of copper covered steel compound bar and production method thereof, comprise rod iron core and fine copper skin, utilize physical cold extrusion principle to squeeze with one heart at described rod iron core outer surface and cover fine copper skin described in one deck, described fine copper skin and described rod iron core are formed between atom at interface and is combined into integrated compound bar.
As further optimization of the present invention, a kind of copper covered steel compound bar and production method thereof, described rod iron core by Q195 ~ Q235 material hot rolling to required specification; As further optimization of the present invention, a kind of copper covered steel compound bar and production method thereof, described fine copper skin is caused slightly larger than described rod iron core external diameter 2 ~ 5mm thin-walled tubular through cold-drawn by T2 red copper.Advantage of the present invention is: a kind of copper covered steel compound bar and production method thereof, design science, production technology easily realizes, production equipment cost is lower, product structure is reasonable, can keep fine copper serviceability, can significantly reduce costs again, save fine copper metals resources, and mechanical property especially bending strength can also be significantly improved.
Accompanying drawing explanation
Below the content expressed by this Figure of description 1 and the mark in figure are briefly described:
Accompanying drawing 1 is a kind of copper covered steel compound bar of the present invention and production method structural representation thereof.
In accompanying drawing 1: 1. rod iron core 2. fine copper is outer.
Detailed description of the invention
Contrast accompanying drawing below, by the description to optimum embodiment, the specific embodiment of the invention is described in further detail.
As shown in Figure 1, a kind of copper covered steel compound bar and production method thereof, comprise rod iron base material 1 and fine copper skin 2, its production method is as follows: cover covers: be placed in by described rod iron base material 1 and wear on material platform, worn by the described fine copper skin 2 slightly larger than described rod iron core 2 ~ 5mm thin-walled tubular and cover described rod iron core 1 outer surface; Dog undergauge: by overlapping the described rod iron core 1 covering described fine copper skin 2, synchronously enter head rolling machine, by one head 10 ~ 12cm partial concentric spreading undergauge, undergauge ratio is 10% ~ 15%; Cold extrusion: by the described rod iron core 1 overlapping the described fine copper skin 2 overlayed on together of spreading undergauge, pierce into cold extrusion unit mould, synchronous cold is squeezed to described fine copper skin 2 and tightly covers described rod iron core 1 outer surface, fine copper outer 2 and rod iron core 1 is formed between atom at interface and is combined into integrated compound bar.According to requirements, outer 2 external diameters of described rod iron core 1 external diameter and described fine copper and wall thickness all can accurately be arranged.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present invention and technical scheme are carried out; or design of the present invention and technical scheme directly applied to other occasion, all within scope without to improve.
