Quench & Temper Systems

Effective quenching and tempering requires the ability to deliver uniformly heated material to achieve optimum product straightness, with minimal cracking through the quench.

Thermatool’s Quench and Temper Systems are designed to meet the exacting physical material properties demanded in many markets including producers of hardened and tempered bar, OCTG & API Products and Food Grade tube & pipe.

Thermatool Quench & Temper Systems

PRECISION QUENCHING

Thermatool’s unique precision quench delivers unparalleled results in the industry. Product straightness is the result of uniform heating followed by precision quenching and can eliminate the need to post heat treat re-straightening. Enhanced metallurgical properties result from programmable control over the quenching process. This is all deliver within a compact equipment footprint. The slot quench rings offer superior control of the hardening process by providing a high velocity, symmetrical shaped flow of quenchant. The modular design provides quick change over between product sizes, and precision quenching of large diameter ranges.

Variable speed turbine pumps are provided to allow precise control over the quench rate, and bounce-back temperatures are programmable for large bar diameters. The quench ring profile prevents scale “clogging” experienced in nozzle type quench barrels. Maintenance is simplified and minimized. Sealed containment boxes are provided to minimize over spray and water loss.

ACCURATE PROCESS CONTROL

Thermatool’s state of the art HAZControl Technology™ offers the next generation in induction heating technology for pipe, tube and bar processing. The system provides a validated analytical model to input material characteristics and size, and outputs optimal power levels downloaded to the VIP® Power Supplies to control surface to core heating rates. The system combines the analytical model to predict inside temperatures while using external temperature measurement and control to achieve optimal hardening and tempering results.

The HAZControl Technology™ system provides greater control over the induction heating process with the added benefit of scrap reduction and a better quality heat treatment. The control system stores modelled temperature profiles for each product. This unique feature enables the individually controlled induction coils to be set at power outputs which will produce a heating affected zone (HAZ) pattern specific to that product, which is essential to the successful processing of specific product chemistries.
