Nitrex Metal received an order from Elvial S.A., an aluminum extrusion company in Greece for a retort furnace. The furnace, which was installed and started up in July 2021, will help Elvial increase production of building materials. The NX-815 E operates with NX Connect software and uses NITREG-C (nitrocarburizing) and NITREG (gas nitriding) technologies for die extrusion. The machine is equipped with air conditioning, an exhaust gas neutralizer and 1,653 pounds (750 kg) of racking made from Inconel 600. The order also included a lifting device. All processes for this furnace are compliant to AMS 2759/10.

SECO/WARWICK will deliver a retort furnace with vacuum purging for oxidation to a tool manufacturer. The furnace for the oxidation process operates under a nitrogen and hydrogen mix and then under steam. It will be adjusted to the individual needs of the tool manufacturer, providing the appropriate final hardness and color of the workpieces. The retort furnace, which will also enable tempering after vacuum purging, will be designed with a customized heating chamber so that it is compatible with the tooling used in the production process and so that the process itself is safe and repeatable. 

L&L Special Furnace Co. Inc. manufactured and shipped a retort furnace to a northeast U.S. manufacturer of motor laminations. The furnace has a work zone of 17 inches square, and the typical load weight is 250 pounds. The retort is removable to achieve the required aggressive cool-down curves. All thermal data is collected and stored from each run through a PLC-based control system. The furnace, which was built in accordance with ASTM standards, was set up to perform both hardening and oxidation during a single heating cycle. To accomplish this, L&L outfitted the furnace with a custom-developed Honeywell control system.
