Copper wire copper tube bright annealing equipment

I. Overview:  

Copper wire annealing equipment is used for copper wire (brass alloy outer sheath) series annealing medium frequency induction heating equipment for on- line annealing , with energy monitoring device, penetration depth and hardness according to customer's specific requirements to achieve stress removal and softening of brass The purpose of the outer sheath of the alloy.  

Equipment introduction   The complete set of equipment is designed and manufactured according to the mechatronic structure. The series inverter medium frequency power supply is a 6-pulse or 12-pulse thyristor KGPS200KW/8KHZ series inverter intermediate frequency power supply (power factor 0.96 or more) , and the load is HTR series induction heating furnace. The set is designed with manual and automatic power adjustment knobs, which are automatically closed-loop temperature control. The external control console selects the computer xp system touch screen control , and can conveniently input heating parameters on the touch screen, such as copper wire specification, heating speed, annealing temperature, etc. After the parameter input, the intermediate frequency power supply temperature closed-loop control system will automatically adjust the output power to meet the production. demand. When a certain fault occurs in the production, the intermediate frequency power supply can be insulated according to the temperature set by the computer to avoid over-burning the copper wire. The equipment is placed according to the user's requirements. Facing the equipment from left to right, the console is placed on the main equipment, which is convenient for the operator to observe the production situation and adjust the parameters conveniently.  

The equipment has perfect safety protection measures, main circuit short circuit protection main circuit, road phase loss protection, main circuit over current protection, low voltage high protection, low grid voltage protection, high cooling water temperature protection, low cooling water pressure protection, thyristor Over-voltage protection, thyristor over-current protection, and sound and light alarm device for faults. The equipment is configured in 200KW, leaving sufficient power margin to ensure continuous and stable production for 24 hours. All exposed conductors are installed in the locked electric control box with eye-catching safety warning signs, and no electrical safety accidents will occur. Each interlocking device can avoid damage to equipment or copper wires caused by manual misoperation.  

Equipment structure The complete equipment covers an area of about 2000*1600mm*1000mm and a center height of 1500mm. The power supply is integrated with the heating furnace body and is fixed by expansion bolts. The equipment is designed with an external operation console, which can be arranged according to the site conditions and is convenient for operation. The installation of the equipment is simple and quick. The user only needs to connect the inlet and outlet pipes to the inlet and outlet of the equipment (one nozzle for each inlet and outlet water), and connect the three-phase four-wire to the upper end of the equipment breaker.
