Technical difficulties

Copper ingots are rolled mainly in a hot state. But hot rolling is difficult because of the intense oxidation of the surface, and therefore rolling rolls have to be coated with special compounds. Since the degree of deformation of copper rolling should not exceed 30%, in order to obtain the necessary thickness of the metal are used multi-stand mills. Due to the fairly high ductility of copper wire or standard profiles (angle, channel , etc.) are obtained by hot pressing or multiple drawing. Immediately after rolling, the metal is subjected to further operations - edge milling, heat treatment and so on.

Range

The following copper shapes are produced by rolling:

• Rolled sheets: sheets, strips, strips;
• Continuous coils;
• Solid bars: Round, square, hexagonal.

Forging and stamping

Copper ingots are forged on forging presses or hammers taking into account rather narrow temperature range of deformation, which is within ^800-9000 С. Above or below these values plasticity of copper rolling decreases, so most of the forging operations - broaching, upsetting, piercing - are carried out at degrees of deformation not exceeding 30%. The use of schemes of all-round irregular compression, such as upsetting with lateral support of the billet, forging in restraining rings , etc. makes it possible to obtain forgings of more complex configuration.

Cold Forging

Cold sheet and bulk forging of copper does not cause any restrictions, but with an increase in the speed of deformation of high viscosity copper may cause sticking of parts of the metal on the deforming tool. Therefore, before punching the billet is subjected to intensive lubrication with emulsions with the addition of low-viscosity mineral oils. When stamping takes into account the fact of intense hardening of copper rolling at the initial stage of deformation.
