CARBURIZE, QUENCH & TEMPER, HEAT TREATING
Without reservation, the key to providing a top quality roll product is in-plant heat treating. Our vertical and horizontal furnaces are the core of Bonell’s unique advantage. We perform our own carburizing and heat treating in-house with our eighteen foot vertical and horizontal furnaces with computer temperature control. These furnaces are used primarily for deep-case carburizing and quench-tempering. In addition, Bonell can expand very large sleeves to close tolerances. These heat shrink-fit procedures allow us to make exceptional re-sleeves, bringing undersized rolls back to print size or making new.
The heat treating process is followed by an oil, brine, or air quench and temper, depending upon the material type and desired properties of the finished roll.
Bonell’s vertical carburizing furnaces are 5’ in diameter and 18’ deep. Quench tanks are 11,000 gallons.Contact Bonell with your specific roll/roller requirements.
