Intermediate frequency induction heating copper wire annealing equipment

1 , Tinjauan:

Intermediate frequency induction heating copper wire (copper tube ) annealing equipment is suitable for on-line annealing of copper wire (brass alloy outer sheath). The penetration depth and hardness are according to the specific requirements of customers to achieve stress removal and softening of the brass alloy. The purpose of the outer sheath.

Equipment introduction The complete set of equipment is designed and manufactured according to the mechatronics structure. Among them, the intermediate frequency power supply is a set of 6- pulse thyristor KGPS200KW/8KHZ intermediate frequency power supply, the load is a set of GTR series induction heating furnace, and the equipment is equipped with a set of reactive power compensation capacitor bank. The device is designed with manual and automatic power adjustment knobs, among which automatic is the temperature closed-loop control mode. The external control console is controlled by PLC (Siemens) and touch screen. The touch screen can easily input heating parameters, such as copper wire specifications, heating speed, annealing temperature, etc. After the parameters are input, the closed loop control system of the intermediate frequency power supply temperature will automatically adjust the output power, thereby Meet production needs. When a certain link in the production fails, the intermediate frequency power supply can be insulated according to the set temperature to avoid overburning the copper wire. The equipment is placed according to user requirements, facing the equipment from left to right, the operating table is placed toward the main equipment, which is conducive to the operator to observe the production situation and facilitate the adjustment of parameters.

Safety protection The equipment has complete safety protection measures, such as water shortage protection, phase lack protection, over current protection, over voltage protection, under voltage protection, high water temperature protection, etc., and there is an audible and visual alarm device for faults. The equipment is configured according to 200KW , leaving enough power margin to ensure continuous and stable production of the equipment for 24 hours. All exposed conductors are installed in the electric control box with a lock, and there are eye-catching safety reminders, so no electrical safety accidents will occur. Each interlocking device can avoid damage to equipment or copper wires due to manual misoperation.

Parameter dipeunteun tina sirkuit utama catu daya frékuénsi panengah dipidangkeun dina tabel ieu:

The inductor is composed of a furnace shell, an induction coil, a stainless steel water collector and a furnace lining. The induction coil is combined with the parameters of the annealed copper alloy tube to optimize the design with special computer software and make it in combination with actual experience. It can ensure the best electromagnetic coupling efficiency under the same capacity. Induction coils with 99.99% of T2 rectangular copper wire made, the induction coil outer insulating electrostatic spray process the epoxy resin insulating layer of high strength, pressure-resistant insulating layer is greater than 5000V .

The inner layer of the induction coil is made of white corundum lining, and the outside of the lining and between the coils are fixed with refractory cement (American Union Mine), which can play a role in insulation and heat preservation. At the same time, the strength of the white corundum lining is further increased, effectively avoiding copper wire damage to the lining.
