Lindberg/MPH shipped an electrically heated, steam atmosphere pit furnace to a tooling manufacturer for steam treating parts. Manufacturers use the steam-treating process to create a uniform blue-black finish on the surface of parts that improves wear and corrosion resistance. The furnace has a maximum temperature rating of 1250°F (677°C), work-chamber dimensions of 22 inches in diameter x 36 inches deep and a maximum gross workload of 1,200 pounds. It is designed for a pit-type installation if required. The custom lid assembly utilizes a pneumatically operated boom lift with electric swing.
Delta H manufactured and supplied twin convection furnace systems to Winston Heat Treating of Dayton, Ohio. The SCAHT-HD series furnaces replaced older tempering systems that were extremely difficult to qualify to Class 5 (+/-25°F). The furnaces had to be heavy duty for rugged daily use in a commercial heat-treating facility. Another challenging design aspect was the ability to heat rapidly but cool just as fast without damage to interior metal. A load heat treated at 1000°F (538°C) could be quickly followed by the next at 300°F (149°C). The result is that the Delta H furnaces can heat and cool in a fraction of the time of the previous systems.
SECO/WARWICK received an order from an international organization in the field of industrial automation for a heat-treatment system. The company aims to establish a captive hardening plant within its machine park. The comprehensive technological line for hardening applications will consist of two vacuum furnaces, one atmosphere furnace and a washer. The furnaces will be used for hardening and vacuum carburizing the elements used in motor reducer production. These parts are used in the production process for automation applications in industries such as automotive, aviation and printing. The vacuum furnaces on order have compact dimensions that meet the customer’s requirements for hardening and carburizing parts, specifically gears, pinions and shafts.
Bodycote, the world’s largest provider of thermal-processing services, announced that its near-term science-based emissions target has been approved by the Science Based Targets initiative (SBTi). SBTi is an independent global body enabling businesses to set and validate emissions reduction targets in line with the latest climate science and strict criteria. The initiative is a collaboration between CDP, the United Nations Global Compact, World Resources Institute (WRI) and the World Wide Fund for Nature (WWF) and one of the We Mean Business Coalition commitments.
Voestalpine High Performance Metals del Perú installed a Nitrex system for nitriding and nitrocarburizing a wide range of components made from high-performance steels. This new addition strengthens the company’s position as a provider of high-tech thermal processes on par with highly industrialized countries and expands its capabilities to meet the needs of industries such as mining, metal, energy and others. The pit-type furnace is designed to process workloads measuring 23.5 inches (600 mm) in diameter x 47.25 inches (1,200 mm) high weighing up to 1,700 pounds (800 kg). Process technologies include Nitreg controlled nitriding, Nitreg-C controlled nitrocarburizing and ONC post-oxidation.
Solar Manufacturing built, shipped and installed a vacuum furnace for a commercial heat-treating and brazing facility in eastern Pennsylvania. The Mentor has stainless steel chamber, a work zone measuring 12 inches x 12 inches x 18 inches and a maximum operating temperature of 2400°F (1315°C) with a workload capacity of 250 pounds. The furnace includes a VHS 6-inch diffusion pump for vacuum performance in the 10-6 torr range, a high-performance 7.5-HP fan motor for internal gas quenching up to 2 bar and the SolarVac fully automated and programmable controls package with a Eurotherm digital recorder.
L&L Special Furnace built and delivered a highly uniform box furnace to a distributor of equipment to maintenance repair and overhaul (MRO) facilities throughout the world. The furnace has working dimensions of 11 inches wide x 10 inches high x 22 inches deep. It is capable of heat treating a wide variety of tool steels – from D-2 to high-speed M-2 tool steel – along with low-temperature tempering. It is equipped with a sealed case for inert-atmosphere capability, as well as a fully functional atmosphere control panel with pressure regulator, flow meter and manual shutoff valve.
