Annealing for
fasteners
Rad-Con’s 100% hydrogen super-high
convection™ (H2SHC™) bell-type
annealing furnaces (BAF) are said to
offer the highest convection flow in
the industry to reduce temperature
variations in a minimum amount of
cycle time, resulting in uniform material
properties with low utility costs.
A typical application for the H2SHC™
system is cold heading quality (CHQ)
wire for fasteners.
Achieve consistent mechanical •
properties on annealed wire and
wire rod
Spheroidise anneal to produce •
CHQ wire for automotive-grade
products
Produce a clean surface free of •
decarburisation of the steel wire
Reduce overall per ton utility costs •
Rad-Con’s FlexLoad™ plenum allows
a variety of multi-stack configurations.
The system includes Rad-Con’s
patented AC/APEx™ atmosphere con-
trol system for regulation of heating
rates and atmosphere flows, according
to wire quality requirements.
AC/APEx™ provides continuous,
closed-loop feedback and adjustment
of atmosphere conditions and tem-
perature profile to match metallurgical
requirements and is designed to
produce annealing results free from
additional decarburisation.
Rad-Con systems reliably provide the
full spheroidisation and protection
against decarburisation that ferrous
CHQ demands.
End-product fastener quality,
downstream machine speed and
drawing die life, which are all
dependent on the uniform properties
achieved during annealing, are
enhanced.
