Continuous casting and rolling production process of oxygen-free copper rod

Abstract

The invention discloses a continuous casting and rolling production process of an oxygen-free copper rod. The continuous casting and rolling production process comprises the following steps of putting electrolytic copper raw materials in a sealed mixing melting furnace for smelting, introducing reduction gas, then discharging from a copper outlet of the sealed mixing melting furnace, flowing into a molten copper casting ladle through a molten copper diversion trench, opening a casting gate of the molten copper casting ladle, continuously and uniformly pouring molten copper to a continuous casting crystallizer through a stainless steel pouring nozzle of the molten copper casting ladle so as to form a continuous casting copper ingot, quickly and uniformly applying oxidation resistant lubricating oil to the surface of the continuous casting copper ingot, sending to a rolling mill so as to be rolled into the oxygen-free copper rod, cooling the oxygen-free copper rod until the temperature of the oxygen-free copper rod is reduced below 80 DEG C, then wiping to remove the oxidation resistant oil from the surface of the oxygen-free copper rod, and then wiping the surface of the oxygen-free copper rod with a small amount of industrial alcohol so as to package and store. By adopting the continuous casting and rolling production process, the quality of the oxygen-free copper rod prepared by adopting the continuous casting and rolling process can be increased.

Description

technical field [0001] The invention relates to the technical field of copper processing technology, in particular to a continuous casting and rolling production process of an oxygen-free copper rod. Background technique [0002] Oxygen-free copper rod refers to the copper rod material with oxygen content below 20ppm. Oxygen-free copper rod usually has a bright appearance, so oxygen-free copper rod is often called bright copper rod. Pure copper material with any deoxidizer residue is mostly used for processing and manufacturing conductive materials for power transmission and signal transmission. The continuous casting and rolling process of copper is the continuous casting and rolling process of copper. Its main feature is that after the refined molten copper is cooled and crystallized by the continuous casting machine to form a copper billet, it does not undergo conventional cooling to room temperature. process, but heat preservation and use the residual temperature of the...

Problems solved by technology

[0003] Because the oxygen content in the oxygen-free copper rod obtained by the conventional continuous casting and rolling process is not easy to control, even if the continuous rolling process is carried out under protected conditions, the oxygen content in the oxygen-free copper rod is often between 200ppm and 500ppm. Sometimes the oxygen content can even be as high as 700ppm or more, so the qualified rate of oxygen-free copper rods produced by the conventional continuous casting and rolling process is low, and the application in the fields of power transmission and signal transmission is subject to many restrictions. The casting and rolling process is further improved to improve the quality of the oxygen-free copper rod prepared by the continuous casting and rolling process
