Annealing for fasteners Rad-Con’s 100% hydrogen super-high convection bell-type annealing furnace ▲ ▲
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.

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:
