200kw Shaft High Frequency Induction Heating Machine for Quenching
1. Induction quenching machine introduction:
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 water cooled 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 if made
from steel, caused the outer surface of the part to heat to a
temperature above the transformation range. Parts are held at that
temperature until the appropriate depth of hardening has been
achieved, and then quenched in oil, or another media, depending
upon the steel type and hardness desired.
2. Application Ranges of induction quenching machine:
Heat Treatment like annealing, normalizing, hardening/quenching,
tempering.
1). Hardware and tools, such as plier, wrench, hammer, ax, screwing
tools and shear (orchard shear).
2). Automobile and motorcycle fittings, such as crankshaft,
connecting rod, piston pin, chain wheel, aluminum wheel, valve,
rock arm shaft, semi drive shaft, small shaft and fork.
3). Electric tools, such as gear and axes.
4). Machine tools, such as lathe deck and guide rail.
5). Various hardware metal parts and machined parts, such as big
shaft, gear (chain wheel), camshaft, chuck and clamp etc.
6). Hardware molds, such as small-size mold, mold accessory and
inner hole of mold.
7). Other metal products.
