Embodiment Construction

[0025] As shown in Figure 1, the technological scheme adopted by the present invention is as follows: continuous casting of oxygen-free copper rods—continuous extrusion of rectangular billets—multi-pass reversible finish rolling (no annealing in the middle)—bell-type gas shielded annealing— Slitting and slitting——finished product inspection——packaging and warehousing

[0026] 1. Continuous casting oxygen-free copper rod

[0027] High-quality No. 1 electrolytic copper is preferred as the raw material. After being melted in a power frequency electric furnace, steel carbon and wood phosphorus sheets are used to cover the reducing agent, and the oxygen-free copper rod is drawn up by the clutch-type vacuum of the traction unit, and then the oxygen-free copper rod enters the take-up device.

[0028] Main process parameters: copper content ≥ 99.95%;

[0029] Copper melting temperature 1150℃±10℃

[0030] Oxygen content of copper rod ≤10PPM

[0031] Leading rod speed 600-750mm / sec ...

Abstract

The present invention discloses great length oxygen-free copper belt producing process, which includes continuously casting oxygen-free copper rod, continuously extruding rectangular blank, several gates of reversible finish rolling, annealing, longitudinally shearing, inspection, packing and other steps. By means of using oxygen-free copper rod as initial blank, continuous extrusion, continuous finish rolling, anti-oxidizing treatment, light gas protection and complete annealing, the present invention obtain great length oxygen-free copper belt product with high performance and good color.

Description

technical field [0001] The invention relates to a production process of a large-length oxygen-free copper strip, in particular to a continuous extrusion method, which is used to form and extrude a soft-state copper strip blank at one time, and then undergo multi-channel continuous rolling and heat treatment to manufacture a large-length oxygen-free copper strip. The production process of the oxygen copper strip belongs to the technical field of new materials. Background technique [0002] At present, the international copper processing technology is developing towards high efficiency, low cost, low energy consumption, short process, and no pollution. However, my country's copper processing technology is still in a relatively backward state. Copper strip is an important part of copper materials. Its processing technology is in a relatively backward state, and the processing technology of the copper strip is as follows: [0003] Copper melting - billet - milling - heating - mu...
