Lindberg/MPH shipped two electrically heated pit furnaces to the automotive industry. The nitrogen atmosphere furnaces, which will be used to heat treat automotive parts, utilize high-velocity forced convection heating systems inside an atmosphere-tight retort chamber and have a maximum operating temperature of 1250°F. The work chamber is approximately 50 inches in diameter and 60 inches deep. The units’ overall dimensions are 101 inches wide x 90 inches long x 148 inches high with a working height of 110 inches and a maximum load gross weight of 10,000 pounds.
Wisconsin Oven shipped a continuous-duty conveyor oven to a U.S. manufacturer that will use it for stress relieving steel snap rings used in automotive parts. The natural-gas-fired oven has a maximum operating temperature of 650°F and a work zone measuring 2 feet, 2 inches wide x 10 feet long x 1 foot high. When preheated, the oven has sufficient capability to heat 350 pounds of steel parts per hour from 70°F to 550°F. Heated air will be delivered in a horizontal airflow configuration through a fully adjustable boxed duct located along the length and across the height of the work chamber.
Stack Metallurgical Group, after installing a hot isostatic press (HIP) earlier this year, is redoubling its commitment to the technology with the addition of a second HIP from Quintus Technologies. The unit has a work zone of 26 inches (660 mm) in diameter and 68.9 inches (1,750 mm) in height. It follows the installation in January of a high-capacity Mega-HIP, which has a work zone of 63 inches (1,600 mm) in diameter and 102 inches (2,591 mm) in height. The new press, which operates at a maximum temperature of 2552°F (1400°C) and a maximum pressure of 30,000 psi (2,070 bar), will be installed at Stack’s recently completed facility in Albany, Ore. Both systems are equipped with the Quintus proprietary uniform rapid cooling (URC) feature, which combines HIP and heat treatment in a single process.
Nitrex Metal entered into an exclusive agreement with Voestalpine AG to bring new innovations in stainless steel hardening technologies to the Czech Republic. As a result of the agreement, Voestalpine added a nitriding system configured to process workloads 31.5 inches in diameter x 78.75 inches high (800 mm x 2,000 mm) that weigh up to 3,850 pounds (1,750 kg). The system complements a previously installed Nitrex system that combined Nitreg-C gas nitrocarburizing technology with ONC post-oxidizing technology for processing firearms.
Gasbarre Products Inc. (Gasbarre) announced that all manufacturing for its Thermal Processing Systems business unit will take place in its 50,000-square-foot facility in St. Marys, Pa., at the end of 2019. In 2011, Gasbarre acquired the J.L. Becker brand of industrial furnace equipment. Over the last eight years, Gasbarre has run parallel manufacturing facilities in Michigan and Pennsylvania for its furnace equipment. Consolidating the manufacturing of its common product lines allows for the most efficient use of its floor space, equipment and manufacturing processes. The company plans to invest in an additional 12,000 square feet of manufacturing space with additional office and conference-room capacity in St. Marys.
The heart of the vacuum furnace system is just as critical as the heart of the human body. Just as it is important to keep your heart healthy and pumping, it is crucial to keep your vacuum furnace system healthy and pumping.
Wisconsin Oven Corp. shipped an indirect-gas-fired walk-in oven to a manufacturer in the technology industry. The heavy-duty oven, which will be used for heat treating materials used in the production of vehicle batteries, has work-chamber dimensions of 12 feet wide x 6 feet long x 10 feet, 6 inches high. Guaranteed temperature uniformity of ±10°F at 190°F was documented with a nine-point temperature uniformity survey in an empty oven chamber under static operating conditions.
Accurate Brazing, based on market feedback, added a second hot isostatic press (HIP) from Quintus Technologies. Both presses are equipped with Quintus’ proprietary uniform rapid cooling (URC) technology, which combines HIP and heat treatment in a single process, and will be installed at Accurate Brazing’s newest facility in Greenville, S.C. The process, called high-pressure heat treatment (HPHT), streamlines the steps involved in material densification and heat treatment. It also enables all processed components to cool uniformly, resulting in minimal thermal distortion and non-uniform grain growth.
Gasbarre Thermal Processing Systems built and commissioned a high-temperature car-bottom furnace for a manufacturer of excavating equipment based in the southern U.S. The furnace has a work zone of 84 inches wide x 144 inches long x 48 inches high with a 16,000-pound load capacity and an operating temperature range of 1000-2282°F (538-1250°C). It will be used for stress relieving, normalizing and other high-temperature processes. The furnace, which replaced an existing furnace, gives the manufacturer improved operating efficiency and higher-temperature processing capabilities.
