One Minute Mentor: Indirectly heated fluidized-bed furnace

Most fluidized-bed furnaces are used at temperatures below 1095 °C (2000 °F), although some manufacturers have furnaces capable of treating components to temperatures through 1205 °C (2200 °F). Initially, the gas flows upward through the permeable base to agitate the particles as the pressure is gradually increased. (b) Eventually, the gas flow is sufficient to lift the small particles of refractory materials and to transform the particle movement into a violent turbulent motion.

In the early 1980s, this furnace technology seemed to be on the right track as an alternative to salt bath technology, showing similar advantages and applications but without the environmental hazard of salt compounds, waste disposal, recycling of salts, and so on. Nowadays it can be concluded that salt bath technology was partially substituted by vacuum technology, but especially for bainitic hardening (austempering processes), salt baths are still commonly used and show a slightly growing tendency, whereas fluidized beds are hardly used any more.

This temperature limitation is related to the wear and tear on the retort materials at high temperatures, which was one of the reasons for the reduced interest in this furnace type after the initial hype.

Nitrex installs nitriding system at Akademi Metalurji

Nitrex Vacuum, Quebec, has installed a turnkey nitriding system at Akademi Metalurji, a full-service commercial heat-treating solutions provider located in Turkey. The project includes a mid-sized pit-type furnace, advanced controls, three process technologies along with accelerated cooling. 

The decision to invest in a new nitriding system was driven by the company’s objective to overcome efficiency and quality challenges faced with their previous furnace at the Gebze facility. The prior system consumed excessive amounts of process gases and yielded inconsistent nitriding results. With the addition of a Nitrex NX-1015 pit furnace, Akademi Metalurji can now save on process gases and production time, while also expanding their heat treatment capabilities to accommodate wider-dimensioned parts. The nitriding furnace offers an effective work zone of 39” diameter by 59” high (1000 x 1500 mm) and can handle a load of up to 4400 lbs. (2000 kg). The supplied library of Nitreg-based recipes is tailored to meet different application requirements, resulting in a hardened surface that is highly wear-resistant. For applications like machinery components, tooling, dies, and molds, where Akademi Metalurji specializes, Nitreg delivers improved tooling performance, ensuring longer service life and higher throughput. Ultimately, this leads to tool cost savings for their customers.

The system was successfully installed at the Gebze facility, located southeast of Istanbul, and commenced operations in April 2023. Since then, it has been running smoothly, delivering excellent results.

Wisconsin Oven ships electrically heated horizontal quench system

Wisconsin Oven, East Troy, announced the shipment of an Electrically Heated Horizontal Quench System to a manufacturer of products for the automotive industry. This system will be used for the solution treatment of aluminum.

The maximum temperature for this horizontal quench furnace is 1200°F and interior chamber dimensions of 2′ wide x 2′ high x 2′ long. The system has the capacity to heat 450 pounds of aluminum parts and the steel basket within 60 minutes. Temperature uniformity of +/- 10°F at set points 850°F and 1050° F was verified with a nine point profile test prior to shipment.

This horizontal quench system provides a 15 second quench delay from when the door begins to open until the load is fully submerged in the tank. The quench is manual, where the operator pulls the load out of the oven and onto the quench elevator using a hook. The quench delay time is recorded and enforced using sensors to detect the start and end of the quench operation, and to stop the process if the quench delay time expires.
