IQ Furnaces

Achieving super fast quenching with superior design.

Heavy Duty

CEC has designed and manufactured a variety of IQ (Integral Quench) furnaces. These machines can be fitted for many heat treatment processes including:

  • Carburizing
  • Ferritic Nitrocarburizing
  • Neutral Hardening
  • Carbonitriding
  • Annealing (Bright)
  • Stress Relieving
  • Carbon Restoration

Our furnaces are heavy-duty and atmosphere tight. The non-drive prechamber is loaded by pusher from the load side and by a back push-pull drive from the heat chamber. These furnaces can have many features, including:

  • Round or rectangular heating chambers that are gas or electric heated
  • Heat Chamber contains alloy circulating fans for atmosphere uniformity
  • Heavy-duty alloy rollers, rails, and muffles ensure low down time
  • Fail safe Nitrogen purge for atmosphere loss of seal
  • Sophisticated to assure safe operation and desired automation
  • Full load, unload and quench automation with transfer cars or gantry cranes
  • Large capacity heated and cooled Quench tanks with programmable agitation speed
  • Integrated separate tempering furnaces
  • Generators and gas control for Endo, Exo, N-Methanol, N, Ammonia atmospheres
  • Conventional or vacuum washers with alkylene and water tanks
  • Companion freezers for martensite conversion

Variety of Sizes

IQ furnaces come in a variety of standard sizes. CEC IQ furnaces are called “Flexcase” (FC) and are followed in our sizing standards with the width x length x height in inches. Therefore, the FC 243624 has a 24” x 36” x 24” workload chamber. Companion Quench, Temper, Washer and Transfer Cars machines are also applied in standard formats. We can send you a quote and literature on our broad line of standard IQ products and discuss any custom solutions that your product requires.
