Quintus Technologies supplied a hot isostatic press (HIP) to Israel’s T.A.G. Medical Products Corp. The HIP, which was installed in May 2022, will ensure the production of implants and surgical tools with the optimal material properties required by the exacting environments in which they are used. Proprietary features such as high-pressure heat treatment (HPHT) and uniform rapid quenching (URQ) enable the press to produce finished MIM parts with maximum theoretical density, ductility and fatigue resistance. According to T.A.G., the Quintus press will serve for implants and minimal cutting tools production, where high material uniformity and good mechanical properties are required.
Safety in the workplace regarding heat treatment connects each and every person who works in either a captive or a commercial shop. We all have an obligation to one another to minimize the risk of accidents and injuries (no matter how minimal or extensive that injury might be).
Lindberg/MPH shipped a gas-fired cyclone pit furnace to a manufacturer. The furnace has a maximum operating temperature of 1400°F (760°C) and a gross load capacity of 2,750 pounds. The medium-velocity burner and combustion train is estimated at 355,000 BTU/hour. The furnace’s load space is 25 inches in diameter and 36 inches high. The outer shell is constructed of industrial steel and has an alloy liner backed up with insulating brick and block insulation.
SECO/WARWICK delivered a roller-hearth furnace to global bearing manufacturer NSK. The furnace, which will spheroidize anneal rings for the bearing industry, will be installed at the company’s plant in Kielce, Poland. The entire automated process line consists of a loading table with a drive, loading elevators with side handling, heating chambers, controlled cooling chambers, cooling tunnels, unloading elevators and tables. It also includes a control cabinet with a complete automated visualization system that provides comprehensive control over the production process. The process line, which is built around the roller-hearth furnace, is intended to be used for the heat treatment of workpieces following downstream processes that are then assembled into bearings used in the automotive sector.
L&L Special Furnace Co. received orders for a floor-standing box furnace for heat treating saw blades and for a large floor-standing, fiber-lined furnace that will be used to stress relieve and temper large steel castings. The box furnace has an effective work zone of 34 inches wide x 34 inches high x 44 inches deep and includes an electric vertical door, an alloy hearth and a complete control system. The furnace's primary function is to heat treat a range of tool steels that are used for saw blades. The floor-standing furnace has an effective work zone of 36 inches wide x 36 inches high x 72 inches deep. It includes a pneumatic vertical door, 24-inch-high convection alloy fan, a complete control system, castable piers and a cast-alloy load platform for forklift loading.
Tenova was awarded two contracts by Tenaris, a manufacturer and supplier of steel pipes, for its mill in Dalmine, Italy. Both contracts are related to the steelmaker’s investment in special steel production. The Dalmine project is divided into three phases, two of which will be supplied by Tenova. The first phase consists of a meltshop ladle furnace that will be used for secondary metallurgical treatment of the liquid steel. Tenova will design and supply a heat-treatment furnace for special steel bars for the second phase of the project. This movable-hood-type furnace is specifically designed to charge very large bars 12 meters (39 feet) long. It is equipped with 34 hydrogen-ready self-recuperative burners capable of using up to 100% hydrogen as a fuel source.
Andritz received an order from CAF MiiRA to supply a wheel heat-treatment line for the company’s manufacturing facility in Beasain, Spain. The plant has been designed for train wheels with diameters of approximately 19.5-59.1 inches (500-1,500 mm). Production is scheduled to begin in the first quarter of 2024. The heat-treatment line will enable automated and flexible operation. Andritz’s scope of supply includes high-temperature pusher-type kilns, a transport system for the pusher cars, chain conveyors, manipulators, tilting table, safety engineering, automation and visualization equipment. The pusher-type kilns feature high energy efficiency in conjunction with heat recovery to heat the combustion air.
L&L Special Furnace Co. Inc. built and delivered a high-uniformity electric box furnace to a valve manufacturer located in the southeastern United States. The front-loading, refractory-lined unit has an effective work zone measuring 22 inches wide x 22 inches high x 20 inches deep. There is a horizontal double-pivoted door with a safety power cutoff switch. A ceramic hearth and standoffs are provided as a workspace. The furnace is equipped with solid-state relays for fast cycle times. These are housed in a NEMA 1 control panel with single-point power connection.
