Attendees of the conference can meet with Linde engineers who will be available to discuss the function and application of the SINTERFLEX carbon control system. The new technology uses continuous atmosphere sampling, a proprietary oxygen probe, and a carbon monoxide analyzer to continuously calculate atmosphere carbon potential and provide a trim gas mixture to maintain carbon potential within a desired, pre-set range.

“The objective of this technology is to maintain a furnace atmosphere carbon potential that contributes to the processing of sintered parts that meet required, or desired, carbon composition and consequent properties,” said Tony Palermo, metallurgy program manager for Linde in North America. 

According to


, there are a number of processing practices which, if not controlled properly, may contribute to the generation of defects or insufficient sintered part properties or appearance, which reduce quality, increase costs, and lead to dissatisfied customers and, ultimately, diminished market share. One of the root causes of these problems resides in the surface decarburization or carburization of the sintered parts which are the result of carbon potential fluctuation in the sintering furnace. “Our Sinterflex system can eliminate those problems by precisely controlling the carbon potential of the atmosphere in real time and produce consistently high quality parts,” Palermo claimed.
