Metal heat treatment
In the event that a protective atmosphere is needed in Metal heat treatment,
it is necessary to balance the gas composition to suit the process.
In order to attain such an atmosphere, KYK has developed a wide variety of unique
technologies to precisely control the furnace atmosphere.
KYK's heat treatment furnaces feature the design of long tunnel-shaped heating chamber
filled with controlled atmosphere through which workpieces are continuously conveyed.
KYK has developed substantially efficient energy saving technology to take full advantage
of the characteristics of gas and electricity sources.
