Lindberg/MPH announced the shipment of a gas fired nitriding pit furnace with built-in retort to the welding industry. This pit furnace is designed for single and two stage nitriding processes and post-oxidation applications. The design accepts either one-piece work baskets or retort baffle or nest trays. The gross load capacity is 5,000 lbs. at 1200°F and the furnace chamber has a diameter of 38” and is 90” tall. The furnace is designed to produce laminar air flow to obtain the required +/- 15°F temperature uniformity.

The nitriding gas flow control system is a fully integrated nitrogen/ammonia mixing system designed specifically for two stage nitriding operation.  This system includes fully automatic recipe control with a unique profile-based recipe screens that make it simple to understand and program.  The touchscreen display interface includes a paperless chart recorder that data logs the critical furnace parameters for quality control.

“This pit furnace is similar to a past order but altered to the customer’s exact specifications. The control system is a complete automated nitriding system that regulates temperature, time and atmosphere for the entire cycle.”
