Danieli Olivotto Ferrè started up a tube roller-hearth annealing furnace at Tenaris Tamsa in Veracruz, Mexico. The furnace is designed to treat steel tubes coming from cold or hot processing with a maximum throughput of 5 tons/hour. It is able to perform different heat-treatment cycles, including normalizing, annealing, tempering and stress relieving. The pipe to be treated has an OD range from 15-120 mm, thickness from 1.5-20 mm and length up to 16 meters (52.5 feet).
Delta H supplied a dual-chamber aerospace heat-treating (DCAHT) system to Sintavia, a Hollywood, Fla-based provider of additive-manufacturing services. The furnace features dual chambers operable to 1200°F and 500°F with precision control and temperature uniformity and a roll-away stainless steel quench tank. The DCAHT system qualifies as Class 2 (+/-10°F) per AMS 2750E and includes all controls, data-acquisition technology and spare-parts package to be in full compliance with all aerospace pyrometry standards, including Nadcap.
Bodycote recently held an official opening ceremony at its new heat-treatment facility in Prague, Czech Republic. The plant, now fully operational and supporting customer requirements, provides a range of heat-treatment services and will support the automotive and general industrial markets in the region.
North Carolina Governor Roy Cooper announced that Bharat Forge America Inc. will build an aluminum forging plant to manufacture automobile components in Lee County, N.C. The $127.3 million investment will create 304 jobs. The new facility will be part of a larger manufacturing center that will create as many as 460 jobs. According to Bharat Forge, the investment will help it create a strong global manufacturing footprint as part of its aluminum strategy.
Over the past few decades, the low-pressure “vacuum” carburizing process has proven time and time again to produce superior part quality.
October 14, 2019
The use of vacuum technology for carburizing has always shown the most potential for improving the manufacturing process by reducing both processing time and the number of manufacturing steps required to produce a part.
Can-Eng Furnaces International Ltd. received an order from Oregon Products to design and commission a continuous mesh-belt austemper heat-treatment system. The high-capacity system integrates a computerized loading system, pre-wash system, atmosphere-controlled mesh-belt austenitizing furnace, molten salt quench conveyor system, post-quench residual salt removal and recycling system, mesh-belt parts drying oven and unloading system. It also includes Can-Eng’s PET system, which provides individual lot/product traceability, detailed process data collection for continuous process improvements and comprehensive Industry 4.0 equipment diagnostics capability.
Extractive metallurgy is an area of our science that deals with the process and methods of gathering and isolating metals from their ores (i.e., natural mineral deposits) and in some instances refining them.
Fives received two contracts to design and supply reheating furnaces to Chinese steelmakers, both with strict requirements on energy consumption and NOx emissions. The first project covers an ultra-low-NOx furnace to reheat long products, such as stainless steel bars, coils or wires, for Yantai Walsin Stainless Steel. Fives will supply a walking-beam furnace with a capacity of 85 tons per hour. The second contract was signed with Shijiazhuang Iron & Steel Company within China’s HBIS Group for two reheating furnaces, each with a production capacity of 130 tons per hour.
Gasbarre Thermal Processing Systems commissioned a 48-inch-wide belt annealing furnace for a global manufacturer. The furnace is equipped with three heating zones that can heat up to 1200°F (650°C). The company required a target belt speed of 10 inches per minute and 2,000 pounds per hour, which were achieved. To aid with unattended loading and offloading, Gasbarre designed a special automated parts feeder and a pneumatic unload mechanism. The furnace also includes an Allen-Bradley PanelView HMI for complete furnace control and data tracking and trending.
