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 Introduction and main characteristics

Series resonant medium frequency induction hardening equipment to be used, namely voltage resonant frequency tracking.induction heat treatment Therefore high efficiency, high power factor. So there is a significant saving effect, electric heating rods 341 degrees per ton of feed. Medium frequency induction hardening equipment level before uncontrollable full-bridge rectifier, does not cause distortion of the waveform in the rectifier section, not related clipping off the corner,induction heating equipment and with a large capacitor filter, so a small number of small interfering harmonics on the grid.
1 simple production operations, access to materials and flexible, high degree of automation, enabling on-line production;
2 workpiece heating speed, less oxidation and decarbonization, high efficiency, good quality forgings;
3 workpiece heating length, speed, temperature, etc. can be precisely controlled, the workpiece is heated evenly, small core table temperature, high control accuracy;. Sensors according to customer requirements elaborate; comprehensive energy-optimized design,heat treatment equipment low energy consumption, high efficiency, lower than the coal production cost, induction hardening equipment to meet environmental requirements, less pollution, while also reducing labor intensity.
