SECO/WARWICK S.A. has supplied two vacuum furnaces that
greatly extend the range of technological possibilities at Z.P.H. Jan Tarapata
in Kolbuszowa, Poland. The scope of delivery includes a VPT-type vacuum furnace
with a high-pressure cooling system and high-vacuum system, isothermal
quenching, vacuum carburizing FineCarb® and pre-nitriding PreNitLPC®. The
furnace enables hardening, tempering, annealing, age hardening, brazing and
vacuum carburizing. The furnace’s technology means heat-treated parts won’t
oxidize and part deformations will be minimized using gas quenching.
The second furnace is a VTR type with vacuum purge and gas
nitriding ZeroFlow® technology. The furnace makes it possible to temper and
nitride while maintaining very high purity loads. Both furnaces are equipped
with modern control systems, enabling them to obtain a very repeatable process
while maintaining high parameters of heat treatment.
