The invention has the beneficial effects as follows: the one, adopt described combination base substrate to be rolled, efficiently solve casting copper base temperature difference in course of hot rolling, thereby roll-force is even, gained copper coin surface smoothness height; The 2nd, the roll-force of roll of having utilized two substrate homogenizing, thus avoided because of the unstable lot of unstable factor of bringing of milling train, and then improved rolling quality; The 3rd, adopt anti-jointing material layer both to prevent the bonding of substrate and casting copper base, the copper base is freely extended in the operation of rolling, can also keep the temperature stabilization of copper base.In addition, compound copper coin is cut, avoided copper coin owing to the soft cutting inconvenience that causes, guaranteed that effectively gained copper coin edge is regular, reduced follow-up arranging process.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described two substrate periphery are connected to of steps A clustered operation is tightly connected, and makes between two substrates and forms seal cavity, and described seal cavity is vacuumized processing.
Adopt the beneficial effect of above-mentioned further scheme to be, adopt seal cavity, can make the copper coin edge of moulding smooth, the sealing space is vacuumized processing, casting copper base was pined for guaranteeing process safety in follow-up adding, avoid air to expand to the influence of product quality, also help between substrate and the casting copper base and combine closely, also be conducive to that casting copper base extends smoothly when rolling simultaneously.
Further, also be included in isolating bar is placed at described casting copper base periphery before being welded to connect in two substrate periphery edges.
Adopt the beneficial effect of above-mentioned further scheme to be, adopt isolating bar can avoid when the upper and lower base plate edge is connected by the connecting plate weldering, causing and the weldering of described casting copper base mistake.
Further, the gained copper coin is heat-treated after also being included in described step C.
Adopt the beneficial effect of above-mentioned further scheme to be, this heat treatment step can make copper coin reach the hardness of regulation.
Further, described substrate is carbon steel material.
Adopt the beneficial effect of above-mentioned further scheme to be, carbon steel is drawn materials conveniently, is convenient to seam utilization repeatedly.
Further, described anti-jointing material layer is barrier film.
Adopt the beneficial effect of above-mentioned further scheme to be, can prevent substrate and the adhesion in the operation of rolling of casting copper base, also help casting copper base simultaneously and extend smoothly.
