Production process of C92200 copper rod:

Raw material preparation: waste brass, waste copper and zinc ingots are used as raw materials, and they are sorted and pre-treated to ensure that the impurity content meets the standard.

Smelting and insulation: The smelting is carried out in an industrial frequency furnace or an electric furnace, and the temperature is controlled at 500~900℃. After melting, the temperature of the copper water is kept stable by the insulation furnace.

Continuous casting: The molten copper water is cooled and formed by continuous casting technology (such as horizontal continuous casting). Some processes use submerged liquid transfer technology to improve efficiency. A single device can produce multiple rods at the same time.

Hot extrusion and polishing: The copper rods after continuous casting are hot extruded (such as 38MN reverse extruder) to improve density and surface finish, and then polishing is carried out to remove surface defects.

Annealing and straightening: Annealing treatment (260℃ stress relief annealing) optimizes material properties, and finally the finished product is obtained by straightening and cutting.

Environmental protection measures: The smoke and waste slag generated during the production process are treated by bag dust removal, wet precipitation and other technologies to achieve resource recycling.

Advanced process technology:

Large-tonnage electric furnace smelting + multi-head continuous casting: significantly improve production efficiency (more than 10 times faster than traditional processes).

Reverse extruder technology: improve product density and strength, and adapt to the production of various grades of copper rods.

Short process: replace the traditional ingot casting-hot extrusion steps by continuous extrusion to reduce costs and energy consumption.

Product advantages of C92200 copper rods

Excellent mechanical properties:

Tensile strength of 275N/mm², yield strength of 140N/mm², elongation of 30%, good toughness and compressive strength (such as compressive strength of 260N/mm² at 0.1% deformation).

Outstanding high temperature performance: creep strength of 110N/mm² at 177℃, suitable for high-temperature steam equipment.

Corrosion and wear resistance:

Good corrosion resistance in air, fresh water and sea water, suitable for corrosion-resistant parts such as valves and bearings.

High hardness (65HB) and wear resistance, suitable for manufacturing mechanical parts such as gears and pumps.

Excellent processing performance:

The machinability is 4.2% of free-cutting brass, supporting lathe processing, stamping and brazing (pay attention to welding temperature control).

Supports hot pressure processing and heat treatment strengthening, easy to customize complex shapes.

Environmental protection and efficient production:

The waste copper recycling process is adopted to reduce resource consumption; the production process is equipped with dust removal and waste slag recycling systems to meet environmental protection requirements.

Automated production lines (such as step-by-step translation) reduce surface damage and improve the yield rate.

Wide application areas:

Used in electrical engineering (high conductivity), instrument manufacturing (precision parts), ship equipment (seawater corrosion resistance) and energy industry (high temperature resistant parts).
