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. The system is said to offer the
following advantages:
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 control 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 temperature 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.
