§ Equipment application
1.The copper rod continuous casting and rolling line can be equipped with different kinds of melting furnaces according to various raw materials (copper cathode or copper scrap of above 94% Cu content).
2.The copper rod continuous casting and rolling machine can produce ETP and FRHC with dia. 8mm.
3.The copper rod continuous casting and rolling machine is designed to produce φ8mm low oxygen and bright copper rods by means of continuous casting and rolling.
§ Equipment feature
1. Crystallizing wheel is in type of “H”, and cooling on every side. External and side cooling is divided into 4 sections, and internal cooling is divided into six sections. Each section’s supplying for water is separately adjusted, and its pressure can be shown in the pressure gauge so that make ingots even cooled, grain refined and high technological adaptability.
2. The tension of steel belt is pneumatic control. Tension can be easily adjusted by adjusting the air pressure. The tension of steel belt is constant after it is set which makes for the stable die chamber.
3. It is with the unique rolling method combining 2-high mould with 3-high mould, which can increase the deformation of ingot in the high-temperature stage.
4. The production line is provided with the function of continuous reverting for rod surface and fast cooling to assure the light and temperature of finished rod can be controlled.
5. By using of optimum design for casting machine, lower the approach span height, which makes the finished ingot as high as rolling center. What’s more, it lowers the install base level of ingot pulling machine, rolling shear, straightener & edge shaver and rolling mill to zero point. It will reduce foundation cost, as well as favor the workers’ operational safety.
6. It is with perfect outlook & lower noise and vibration.
7. The transmission system is in type of DC motor fully-digital speed adjusting.
8. Easy to disassemble and assemble.
9. High efficiency & quality of production but low dissipation energy.
