Abstract

In a method for the production of semi-finished copper products, first copper is melted and cast to produce copper anodes, in one casting procedure, within multiple ingot molds, subsequently copper cathodes are formed by electrolysis, using at least one of the copper anodes, and then these copper cathodes are processed further to produce semi-finished copper products. A long-term coating is applied to at least one of the ingot molds as a wash, a sulfur-free wash is applied to the ingot mold and/or part of the work pieces cast in the ingot molds is directly processed further to produce semi-finished copper products. A method and an apparatus applies a wash to an ingot mold and a system produces semi-finished copper products.

First claim

What is claimed is:

1. A system for producing semi-finished copper products
comprising:
(a) a refining furnace;
(b) ingot molds disposed behind and fillable from the refining furnace;
(c) an electrolysis bath;
(d) an anode transport for transport of anodes cast in the ingot molds to the electrolysis bath;
(e) a processing device disposed after the electrolysis bath for further processing of work pieces cast in the ingot molds, to produce semi-finished copper products;
(f) a cathode transport for transport of cathodes from the electrolysis bath to the processing device; and
(g) a bypass transport between the ingot molds and said processing device for transporting the work pieces cast in the ingot molds to said processing device;
wherein the work pieces bypass the electrolysis bath;
wherein the anode transport and the bypass transport have a common conveying device;
wherein the common conveying device transports work pieces from the ingot molds to the electrolysis bath as anodes, in a direction of a further anode transport, and work pieces from the ingot molds in a direction of a further bypass transport different than the direction of the further anode transport.

2. The system according to claim 1 , wherein the ingot molds are disposed on a common ingot mold support.

3. The system according to claim 2 , further comprising an application apparatus for application of a wash, wherein the application apparatus comprises a working region disposed in a region of the ingot mold support.

4. A system for producing semi-finished copper products
comprising:
(a) a refining furnace;
(b) ingot molds disposed behind and fillable from the refining furnace;
(c) an electrolysis bath;
(d) an anode transport for transport of anodes cast in the ingot molds to the electrolysis bath;
(e) a processing device disposed after the electrolysis bath for further processing of work pieces cast in the ingot molds, to produce semi-finished copper products;
(f) a cathode transport for transport of cathodes from the electrolysis bath to the processing device; and
(g) a bypass transport between the ingot molds and said processing device for transporting the work pieces cast in the ingot molds to said processing device;
wherein the work pieces bypass the electrolysis bath; and
wherein said further processing device comprises a furnace, a press, a casting device and/or a rolling mill.

5. The system according to claim 4 , wherein the ingot molds are disposed on a common ingot mold support.

6. The system according to claim 5 , further comprising an application apparatus for application of a wash, wherein the application apparatus comprises a working region disposed in a region of the ingot mold support.
