A Toronto Canada-based manufacturer has ordered a new vacuum tempering/gas nitriding furnace from Seco/Vacuum, a Seco/Warwick Group company.

The partner, a manufacturer of flight-critical helicopter masts, turbine shafts, engine thrust links, and safety critical nuclear components, will use the new furnace for nitriding and nitrocarburizing and can process loads up to 63 inches diameter x 175 inches deep with a load capacity of 13,200 pounds.

The customer is adding new heat-treating capabilities to handle larger loads and configurations as well as increased production capacity.

Seco/Vacuum’s retort nitriding furnaces achieve optimum results by using uniform high convection heating, precision nitriding potential and ammonia control, along with vacuum purging to reduce operating costs to process a variety of metals. The proprietary ZeroFlow® control technology uses only ammonia as a process gas thereby reducing gas usage and gas emissions.

Seco/Vacuum’s manager director, Peter Zawistowski, said, “We are very pleased to collaborate with this precision manufacturer to enable new state-of-the-art nitriding and nitrocarburizing capabilities in their Canadian facility. The ZeroFlow pit retort furnace with vacuum purge incorporates a unique process developed by Seco/Warwick to enable precision nitriding at lower cost and with lower emissions than legacy technologies.”

The new pit nitriding furnace is significantly larger than Seco/Vacuum’s standard maximum size. At 175 inches deep, it’s nearly 80 percent deeper than the standard 98-inch furnace. With a working temperature range of 300° – 1,300°F (150° – 700°C) and temperature uniformity of +/-5°, the furnace boasts the lowest ammonia consumption in the industry and includes a burn-off stack to neutralize gas emissions from the system, making it the most environmentally responsible nitriding furnace in the industry.

Component manufacturers and in-house heat-treating departments in aerospace and land-based turbine markets frequently process long, oversized, dense power transmission components, and Seco/Vacuum’s Pit Nitriding furnace with vacuum purge is the modern option for achieving precision nitriding with the lowest emissions possible.
