4. It covers a small area and is easy to operate. It can be learned in a few minutes.
5. Especially safe, the output voltage is lower than 36V to avoid high voltage electric shock hazard.
6. The heating efficiency is as high as 90%, and the energy consumption is only 20% - 30% of the high frequency of the old electronic tube. In the standby state, it hardly needs electricity and can work continuously for 24 hours.
7. The inductor can be disassembled and replaced freely and quickly. The ultra fast heating greatly reduces the oxidation deformation of the work-piece.
8. The latest environmental protection products, which replace the heating of oxygen, acetylene, coal and other dangerous goods, are safer and safer without open fire.
9. The equipment has perfect automatic protection functions of over-current, over-voltage, over temperature, water shortage and lack of phase, and is equipped with fault self diagnosis alarm system.
10. The equipment has the control function of constant current and constant power, which greatly optimizes the metal heating process, realizes efficient and rapid heating, and gives full play to the superior performance of the product.

Heating Inductor: Total 3 Sizes, 1 Set each size.
Water-Water Cooling System:1Set

1.Automatic Feeding System: The workers put the steel bars on the storage rack and sort well,then the automatic feeding system will transmit the bars to the parallel roller.
2.Induction hardening:With stable running speed of the driving system,the transmission system will deliver the steel bars into the induction heater.The infrared thermometer will monitor and control the steel bar temperature automatically in the processing of preheating--temperature measurement--warming up--temperature measurement.After bar temperature reaches to the target quenching temperature, they will be cooled in the cooling device.Then the transmission system will deliver bars to the feeding system to wait for next heat treating.At the same time,the hardening rejection will be isolated.
3.Tempering System:The steel bars after hardening processing will be transmitted to the induction heaters for reheating to the target temperature under the infrared thermometer control.Then the steel bars will enter the cabinet to preserve heat.After delaying the heat preservation time,the straightened bars will be delivered to the parallel rollers.
4.Automatic Discharging System:The bars will be transmitted to the discharging system for natural cooling.
5.Inspection and Storage.

a) When installing the impedance, the front end shall not be too far beyond the center line of the extrusion roll, which is generally controlled within 3-4 mm.
b) When adjusting the impedance, do not touch the edge of the tube, otherwise the magnetic rod is easily carried away by the tube, and the distance should not be too large.
c) In the process of winding the impedance, care should be taken not to wrap it too thick, not to wrap it too thin. It should be properly determined according to the diameter, wall thickness and inner diameter of the produced steel pipe. It should ensure the water cooling gap in the middle, and there should be measures to prevent breakage.
d) During the production process, the position of the magnetic rod and whether it is taken away or broken shall be checked frequently, and the wire drawing or sundries hanging on the magnetic rod shall be removed frequently.
e) In the normal production process, short magnetic rods can be attached on both sides of the inductor, which can improve the welding efficiency (two functions: one is to strengthen the proximity effect of the tube blank edge under the inductor, reduce its eddy current loss, increase the welding current, and thus improve the welding efficiency; the other is to concentrate the inductive current on the upper half of the tube blank, which can reduce the loss of the tube back).
f) In the case of short magnetic rods, some short magnetic rods can be placed in the tube behind the magnetic rods during adjustment to make up for the insufficient length of the short magnetic rods.
g) During normal production adjustment, pay attention to the cooling of the magnetic rod, so as to reduce the service temperature of the magnetic rod and extend its service life.
