The functions of copper rod continuous casting equipment

Copper rod continuous casting equipment plays a crucial role in the production process of copper rods, covering multiple stages from the melting of electrolytic copper to the forming of copper rods. The following are the main functions of copper rod continuous casting equipment:

1. Melting and insulation

Melting furnace: usually using a power frequency induction furnace, it is used to melt raw materials such as electrolytic copper plates or waste purple copper into copper liquid. The melting furnace is equipped with a loading port and a slag removal port, which facilitates continuous feeding and slag cleaning

Insulated furnace: also a power frequency induction furnace, used to control and stabilize the temperature of copper liquid and the height of crucible liquid level. The insulation furnace is equipped with a liquid level probe, which is used to control the liquid level height and automatically control the temperature by changing the voltage of the sensor

2. Casting and Cooling

Casting equipment: including graphite crucibles and core rods, used to cast copper liquid into copper rods. The core rod needs to undergo stretching, peeling and other treatments before entering the crucible to ensure the quality of the casting rod

Cooling chamber: located at the top of the crucible, equipped with nozzles for cooling the casting rod. Fill the cooling room with protective nitrogen to prevent oxidation of the copper rod. Adjusting the water volume in the cooling chamber can control the temperature of the rod before cooling and rolling

3. Rolling and Forming

Rolling mill: A straight, 45 ° cross enclosed rolling mill is used to roll cooled copper rods into copper rods of the desired diameter. Nitrogen is introduced into the rolling mill to prevent oxidation of the rollers and copper rods, and emulsion is introduced to cool the rollers and copper rods

Straightening machine, rolling shear machine, deburring machine, etc.: These devices are usually located after the rolling mill and are used to straighten, shear, and deburr the rolled copper rod to improve its surface quality and dimensional accuracy

4. Packaging and Closing

Rod winding machine: The rolled and processed copper rod is wound into a circle for easy storage and transportation. The weight of the circle can be determined according to the handling equipment

Retraction device: used to collect coiled copper rod rings and perform subsequent processing such as packaging or loading

5. Automated Control and Monitoring

Electrical control system: using programmable logic controller (PLC) and human-machine interface touch screen to perform full line linkage control of the main and auxiliary machines, as well as detect and display the operating parameters and faults of the equipment

Temperature measurement system: used for real-time monitoring of the temperature of copper liquid and copper rod, ensuring the stability of the production process and product quality

6. Environmental Protection and Energy Conservation

Protective gas generation device: In order to reduce the oxygen content in copper, the protective gas must contain hydrogen gas. The protective gas components include nitrogen, hydrogen, and carbon monoxide, which are used to prevent oxidation of copper liquid and copper rods during the production process

Emulsion system: provides cooling for the rolling mill and oxygen free copper rod, while forming a protective film on the surface of the copper rod to prevent oxidation and improve the service life of the rolling mill. The emulsion system can continuously circulate, filter, and heat exchange the emulsion through a heat exchanger, achieving energy conservation and consumption reduction

The functions of copper rod continuous casting equipment cover multiple aspects, including melting, insulation, casting, cooling, rolling, forming, packaging, rod closing, and automation control and monitoring. It is an indispensable and important equipment in the production process of copper rods
