Copper rod is the main raw material of the cable industry, which can be divided into low-oxygen copper rod and oxygen-free copper rod. Today, we will focus on introducing low-oxygen copper rod, exploring its production process, advantages and disadvantages, and applicable production equipment.
The low-oxygen copper rod is produced by continuous casting and rolling process. After the raw materials are melted in the reverberatory furnace, the copper liquid enters the casting machine through the holding furnace to form a billet, and then undergoes multi-pass rolling to finally obtain the low-oxygen copper rod. The produced copper rod is thermally processed structure, the original casting structure has been broken, and the oxygen content is generally (200-400) ppm.
1.Advantages of Continuous Casting and Rolling Production Line in Production of Low Oxygen Copper Rods
(1)Low requirements for raw material
Continuous casting and rolling production line to produce low-oxygen copper rods mainly melt the raw materials through gas combustion. During the combustion process, through oxidation and volatilization, some impurities can be reduced to a certain extent from entering the copper liquid. Therefore, the continuous casting and rolling production line has relatively low requirements for raw materials.
(2)Advantage in process
The low-oxygen copper rod produced by the continuous casting and rolling production line has a high output, and the output can generally reach 5-16 tons per hour. The take up of finished copper rod adopts basket coiler, which is convenient for the next process of wire drawing machine. The take-up weight is large, generally up to 3-5 tons per reel.
(3)High product quality
The low-oxygen copper rod produced by the continuous casting and rolling production line is of high quality. The copper rod produced by this process has a uniform internal structure, relatively low oxygen content, smooth copper rod surface, and is easy to process. It can meet the requirements of most cable manufacturer's requirements.
2.Disadvantages of continuous casting and rolling production line
(1)High equipment investment
The production of low-oxygen copper rods by the continuous casting and rolling process requires a one-time investment in workshops, furnaces, continuous casting and rolling production lines and other equipment, so the initial investment is relatively large.
(2)High energy consumption
The production of low-oxygen copper rods requires high temperatures, so energy consumption is large, and a large amount of electricity and fuel are required in the production process.
(3)High cost of environmental protection
The production of low-oxygen copper rods by continuous casting and rolling production line will produce a certain amount of waste water and waste gas, and the discharge will have a certain impact on the environment. Therefore, certain governance and treatment are required, and the environmental protection cost is relatively high.
3. Continuous casting and rolling process required equipment recommendation
There are mainly two types of continuous casting and rolling equipment for producing low-oxygen copper rods, one is the US SOUTHWIRE equipment, and the other is the German CONTIROD equipment.
SOUTHWIRE's equipment adopts advanced technology, which can produce high-quality, high-precision copper rods, and also has very high production efficiency. CONTIROD equipment is known for its high quality and reliability. Their equipment uses automation technology, which can greatly improve production efficiency and reduce manual intervention. At the same time, it is also adjustable and can be adjusted according to production needs.
While SOUTHWIRE and CONTIROD have a lot in common in the manufacture of copper rod production equipment, they each have some disadvantages. For example, SOUTHWIRE's equipment has high production efficiency, but the cost is correspondingly high. Although the equipment of CONTIROD is of high quality, its production efficiency is slightly lower than that of SOUTHWIR.
To overcome these limitations, many copper rod production equipment manufacturers have combined the technologies and features of SOUTHWIR and CONTIROD. LINT TOP's copper rod production facility is an example. LINT TOP's equipment combines the efficient production of American SOUTHWIRE equipment with the high quality and adjustability of German CONTIROD equipment. This enables LINT TOP's equipment to have extremely high production efficiency and excellent product quality, while reducing production costs.
After years of practice and customer feedback, LINT TOP is considered to be one of the best copper rod production equipment manufacturers in China.
