250KW Touch Screen Induction Heat Treatment Machine For Induction Hardening


250KW Touch Screen Induction Hardening Machine 80KHZ Frequency 0


Induction hardening is a process used for the surface hardening of steel and other alloy components. The parts to be heat treated are placed inside a copper coil and then heated above their transformation temperature by applying an alternating current to the coil. The alternating current in the coil induces an alternating magnetic field within the work piece which causes the outer surface of the part to heat to a temperature above the transformation range.

The components are heated by means of an alternating magnetic field to a temperature within or above the transformation range followed by immediate quenching. It is an electromagnetic process using a copper inductor coil, which is fed a current at a specific frequency and power level.

The induction hardening process has several heating methods and all have suitable heating workpieces.


One-time induction heating hardening method:

  • One-time induction heating or simultaneous induction heating is the most common induction hardening method. When this method uses two rectangular tubes surrounding the workpiece surface for rotary heating, it is conventionally called a Single Shot.
  • The advantage of this induction heating method is to complete all the workpiece surface area induction heating jobs at a time. Therefore, its operation is simple, productivity is high, and it is suitable for heating the workpiece area is not too large. For heating the particularly large area workpiece, adopt the one-time heating method, it requires considerable power and high investment cost.
  • The most common examples of one-time induction heating hardening are small and medium modulus gears, CVJ bell-shaped shell bars, inner raceways, carrier wheels, support wheels, leaf spring pins, pullers, valve ends, and valve rocker arm arcs, etc.

Scanning induction hardening method:

  • When the workpiece heating area is large, and the induction heating power supply is small, this method is often used. At this point, the calculated heating area S refers to the region contained by the induction ring. Therefore, with the same power density, the induction heating machine required power is small, the competitive induction hardening equipment investment cost is low, suitable for small batch induction hardening production, typical examples are large-diameter piston rod, corrugated roll, roll, oil pipeline, sucker rod, rail, machine tool guide rail and so on.

Subsection one-time induction heating quenching method:

  • Typical examples are the multiple camshafts induction hardening, each time heat one or more cams, after finish this time induction quenching, heating another cam part, the gears are hardened tooth by tooth can also be included in this category.

Subsection induction scanning hardening method:

  • Typical examples are valve rocker shafts or variable speed shafts induction hardening, where multiple parts of a shaft are scanned for induction quenching, the quenching widths may be different, and tooth by tooth scanning quenching may also be included in this category.

Induction heating and hardening in liquid:

  • Induction hardening in the liquid, means the induction coil and the workpiece heating surface are immersed in the induction hardening liquid, heated, due to the heating surface power density being greater than the surrounding quench fluid cooling rate. Therefore, the surface heats up quickly. When the inductor is powered off, the surface of the workpiece is hardened due to the heat absorption of the workpiece core and the cooling of the hardening fluid.
  • This method is generally suitable for steel workpiece which requires a less critical cooling rate. When the workpiece is placed in the air and the induction coil is powered off, the heat of the surface is absorbed by the center of the workpiece. When the cooling rate of the heated surface is greater than the critical cooling rate, the workpiece is hardened, which is similar to the quenching in the liquid.

Short heating times

  • Production rates can be maximized.

Optimized consistency

  • Induction heating eliminates the inconsistencies and quality issues associated with open flame, torch heating, and other methods.

Extended fixture life

  • Induction heating delivers heat to very small areas of your part without heating any surrounding parts. This extends the life of the fixturing and mechanical setup.

Environmentally sound without burning fossil fuels

  • Induction is a clean, non-polluting process. Improves working conditions for employees by eliminating smoke, waste heat, noxious emissions, and loud noise.

Effective energy consumption

  • This uniquely energy-efficient process converts up to 90% of the energy expended energy into useful heat; batch furnaces are generally only 45% energy-efficient. Requires no warm-up or cool-down cycle.

Flexible adaptation to the hardening tasks


Closed loop computerized process control and compatibility with overall process automation
