The production process and product advantages of C24000 copper tube are as follows:

Production process

Melting and continuous casting technology

The cathode copper and phosphor copper alloy (1200℃) are melted in an industrial frequency furnace, and then the copper tube billet is formed by a horizontal continuous casting process. This process combines planetary rolling (such as a three-roll planetary rolling mill) and disc drawing technology to efficiently produce large-size tube billets and improve product consistency and dimensional accuracy.

Some processes introduce electromagnetic stirring devices to refine grains and reduce defects such as pores and cracks, improving the uniformity of copper tube wall thickness and organizational density.

Rolling and stretching

Long-stroke tube rolling mills and high-speed tandem drawing machines are used, combined with floating core head stretching technology to ensure that the inner and outer surfaces of the copper tube are smooth and have high dimensional accuracy.

Planetary rolling (such as horizontal continuous casting-planetary tube rolling method) significantly improves production efficiency and is suitable for spinning of internally threaded copper tubes.

Post-processing process

Annealing: The net chain bright annealing technology is used to make the surface of the copper tube free of oxidation spots and keep it smooth.

Straightening and testing: High-precision straightening machines ensure straightness, and Swiss spectrometers and other equipment ensure stable mechanical properties.

Product advantages

Excellent mechanical properties

It has both high strength and good plasticity, can withstand cold and hot pressure processing, and is suitable for complex forming (such as thin-walled tubes and corrugated tubes).

Outstanding corrosion resistance

It performs well in the atmosphere, fresh water and sea water, and is suitable for corrosion-resistant scenes such as ships and heat exchangers.

Wide processing adaptability

It supports cold/hot processing, welding, brazing, and the surface can be polished, sandblasted, etc., to meet the needs of construction, electronics, decoration and other fields.

Diverse sizes and specifications

The outer diameter range is 2-914mm, the wall thickness is 0.2-120mm, and the hardness and shape can be customized (such as hexagonal tubes and rectangular tubes).

Environmental protection and production efficiency

It adopts a short process of continuous casting and rolling, with low energy consumption and high yield rate; waste materials (such as copper chips and scraps) can be recycled.
