Production process:

Raw material preparation: The production of C79200 copper rods usually uses scrap copper (such as scrap brass and scrap copper) as the main raw material, and impurities are removed through pre-treatment steps such as sorting and cleaning.

Smelting process: The sorted raw materials are added to the furnace with electrolytic copper, zinc ingots, etc. for smelting, and the temperature is usually controlled between 1050℃ and 1100℃. Slag removers are added during the smelting process to remove impurities, and insulation treatment is used to ensure uniform molten liquid.

Continuous casting and extrusion: The smelted copper liquid enters the continuous casting link and forms a continuous casting rod after cooling. It is then further processed by a reverse extruder to achieve the required size and performance requirements. This process includes hot extrusion, skinning and annealing to improve the density and surface finish of the product.

Scrap recovery: The scraps generated during the production process will be collected and reused to reduce waste and reduce production costs.

Environmental protection measures: The entire production process is equipped with a bag dust removal system to effectively reduce smoke and dust emissions. At the same time, wastewater is reused after wet screening and sedimentation treatment to ensure that environmental protection standards are met.

Product advantages:

Excellent chemical composition: C79200 copper rods are mainly composed of copper, zinc and lead, of which the copper content is about 70%-76%, the zinc content is about 17%-20%, and the lead content is about 0.5%-1.5%. This composition ratio gives it good electrical conductivity, thermal conductivity and wear resistance.

Excellent mechanical properties: C79200 copper rods have high tensile strength (350 MPa), yield strength (160 MPa) and Brinell hardness (80 HB), while the density is about 8.4-8.6 g/cm³ and the melting point is between 900-930℃. These characteristics make it perform well in casting and processing.

Wide range of applications: Due to its excellent physical and chemical properties, C79200 copper rods are widely used in aerospace, electricity, petrochemicals, ships, machinery, electronics, environmental protection and other industries.

Environmental protection and energy saving: The use of advanced large-tonnage horizontal continuous casting technology and reverse extrusion technology not only improves production efficiency, but also reduces metal loss and environmental pollution. For example, some production lines can simultaneously continuously cast 64 products of different specifications, and the production efficiency is more than 10 times higher than that of traditional processes.

Stable quality: Through modern production lines and single-machine control technology, combined with strict process control, the quality of C79200 copper rods is guaranteed, with high yield and stable performance.
