Copper rod lead-in device, copper rod production device and copper rod production method

Abstract

The invention provides a copper rod lead-in device, a copper rod production device and a copper rod production method. The copper rod lead-in device comprises a die sleeve, an inlet casing pipe and awater cooled jacket, wherein the die sleeve is a hollow pipe body; the inlet casing pipe is a hollow pipe body, and the die sleeve is at the upper end of the inlet casing pipe in a supported mode; thewater cooled jacket comprises a body, an inner shell and an outer shell, the body is a hollow pipe body, the body sleeves the periphery of the inlet sleeve, a tubular outer shell sleeves the outer circumference of the body, and the tubular inner shell further sleeves between the body and the outer shell, so that an inner ring space is formed between the inner shell and the body, and an outer ringspace is formed between the inner shell and the outer shell; and a water return hole which communicates with the outer ring space is formed in the inner shell, a water inlet channel and a water return channel are formed in the body, the water inlet channel communicates with the inner ring space, the water return channel communicates with the outer ring space, and the water flow passes through thewater inlet channel to enter the inner ring space, enters the outer ring space from the inner ring space via the water return hole and flows back to the water inlet channel from the water return channel. The high-temperature-resistant die sleeve is used for guiding a copper rod, the water cooled jacket is used for circularly cooling the die sleeve, and the service life of the die sleeve is prolonged.

Description

technical field [0001] The invention relates to the field of copper rod manufacturing, in particular to a copper rod introducing device, a copper rod production device composed of the same, and a copper rod production method. Background technique [0002] Copper rods are necessary blanks for the production of copper wires such as wires and cables, enameled wires, and electronic wires, and copper wires are one of the important basic materials for industries such as electronics, electricity, and communications. The production of oxygen-free copper rod by dip-coating method is to smelt the electrolytic copper plate into copper water, use the ability of cold copper rod to absorb heat, and use a thinner cold pure copper core rod, which is driven by the copper rod driving device and enters vertically through the introduction device. A coating room that can maintain a certain liquid level. The copper liquid in the holding furnace flows into the coating room, so that the copper wate...

AI Technical Summary

Problems solved by technology

At present, in the process of introducing the peeled copper rod into the coating room, the introduction accuracy is poor, the high temperature resistance is poor, the use efficiency is low and the service life is short

And the sealing of the introduction device is not tight enough, so that the copper rod cannot be produced in a complete vacuum state
