Fasteners and fittings

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. quality, downstream machine speed and drawing die life, which are all dependent on the uniform properties achieved during annealing, are enhanced.
