induction hardening machine heating principle

induction hardening machine induction heating, induction heating principle engineer explained that:heat treatment equipment the workpiece into the sensor, the sensor input is generally intermediate frequency or high frequency alternating current (1000-300000Hz or higher) hollow brass. Generating an alternating magnetic field with the frequency of the induced current in the workpiece, the workpiece induced current distribution is uneven, the surface of strong, weak in the interior,Induction soldering equipment the center portion close to 0 by using the skin effect enables rapid heating of the surface, the surface temperature within a few seconds up to 800-1000 o C, and the temperature rise is small core parts.

Note the use of induction hardening machine

induction hardening machine room should be well ventilated, kept clean, tidy and dry. The device must have two more to start operation, and specify the person in charge of the operation.heat treatment equipment The operator should be familiar with and abide by quenching equipment rules, and regulations Wear protective equipment. Workpiece should deburring, iron and grease, or prone to arcing, but also to prevent the workpiece when operating in contact with the sensor to produce arcing. Use induction hardening machine, should pay attention to electrical, mechanical and hydraulic transmission and other safety procedures. Equipment required to repair by hand, before repair discharge of capacitors discharge rods. No live repair.
To prevent burst wounding high induction heating large parts, CNC quenching machine must strictly abide by the rules and appropriate heat treatment process planning large heat during operation. Should be carried out on a large piece by piece ultrasonic testing, where after testing found white spots, loose piece of serious defects such as segregation and prohibit high-frequency heating equipment. Workpiece should deburring,Gold melting machine iron and oil to prevent arcing. Production operations, you must specify the person in charge, the operator must be familiar with and abide by the rules of CNC quenching machine.

induction hardening equipment classification

induction hardening equipment types are divided into: frequency, low frequency, medium frequency, super audio,induction heating equipment HF, UHF several, according to the hardening depth need to select the appropriate frequency. The greater the depth of hardened layer, the lower the required frequency, and vice versa, is higher.
Currently induction hardening to IF, super audio, HF, UHF-based.
IF generally SCR, IGBT induction power to do useful intermediate frequency than the SCR energy saving,induction heating equipment but the price is higher than the SCR. Relatively speaking, IGBT is the development trend, because of its high conversion efficiency, and stable performance, internal soft-switch, not prone to failure.

Induction hardening machines introduced

Induction hardening machines can be applied to IF quenching of steel, tool steel, molybdenum,Melting machines chromium cast iron and gray cast iron and other metal materials; surface heating, does not destroy the original mold of accuracy and finish, minimal deformation of the mold, without subsequent processing, technology has changed the traditional mold processing.
Induction hardening machines uniform heating, the hardened layer up 2-3mm. High efficiency, heat speeds up 100-500mm / min.Induction annealing machine Mold modulus using off-line programming, the software automatically generates quenching path and procedures to import the machine can be used directly quenching. Induction hardening machines craft good controllability, by adjusting the current, frequency, sensing distance, speed, coolant flow and concentration to achieve different process requirements. Equipment parts and key parts are world famous brands and high reliability.
