Atmosphere thermal processing improves the properties of fabricated metals. Operations include annealing, brazing, sintering (for powdered metals, metal injection molding and additive manufacturing) and glass or ceramic-to-metal sealing.
SECO/WARWICK received an order from a U.S. manufacturer of flat-rolled aluminum sheet for a sow and T-bar preheat furnace system to achieve maximum product quality, energy savings and melt safety. The furnace offers optimum airflow management and a heating system that promotes efficient heat transfer throughout the work. It includes a patented movable baffle system and fixed base airflow spacers for maximum heat transfer to varying height loads. The system is PLC-controlled with remote I/O and dual operator-interface control stations.
Ebner received an order for a bell annealer facility from Japan’s Nisshin Steel Co. Ltd. The facility will include four heating bells, six 6 HICON/H2 workbases and two cooling bells.

Thinking back to our high-school days often brings a smile to our faces. As a freshman, the daunting task of picking a foreign language to study fell to The Doctor’s mother, who immediately chose Latin for him.
Wisconsin Oven Corp. shipped an electrically heated annealing furnace to a firearm manufacturer. The conveyor furnace, which has a maximum temperature rating of 1400°F (760°C) and a normal operating temperature of 572-1202°F (300-650°C), will be used for annealing an assortment of brass and bronze firearm caps. Work-chamber dimensions measure 3 feet wide x 9 feet long x 6 feet high.
Magnetic Specialties shipped a 360-KVA, three-phase, 60-HZ transformer for use in wire annealing. The transformer features an extended primary winding with multiple taps to adjust the output voltage of the high-current secondary. The tap can easily be changed via the three-phase tap switch mounted to the front of the enclosure.
L&L Special Furnace Co. Inc. supplied an electric box furnace to a Midwestern engine manufacturer that produces parts for large industrial engines, motors and steam generators. The furnace, which has an effective work zone of 22 inches wide x 18 inches high x 22 inches deep, is used for hardening and annealing of a range of components employed in equipment manufacturing. The unit includes a complete digital control system, over-temperature protection and a counterbalanced vertical door for ease of loading.
Lewco sold a custom car-bottom oven rated for a maximum temperature of 1300°F to an industrial manufacturer. The electrically heated oven, which will be used for annealing steel parts, has a workspace of 72 inches wide x 140 inches deep x 90 inches high. Manufactured and designed to NFPA 86 Class B standards, it is supplied with a rear-mounted heater box with 324 kW heat input and a 38,000-CFM high-efficiency circulation fan delivering dual airflow evenly throughout the workspace.
Kobe Steel Ltd. is investing in a new continuous annealing line, with cutting-edge heat-treatment functions, for steel sheet at its Kakogawa Works in response to growing demand for automotive ultrahigh-strength steel (UHSS). The facility, which is scheduled to start up in February 2021, will combine a continuous annealing line with hot-dipped galvanizing and galvannealing equipment. The production line and associated equipment will produce both cold-rolled steel and hot-dipped galvanized/galvannealed steel.
Andritz received an order from Shandong Nanshan Aluminum Co. Ltd for an annealing line and a chemical processing line. Commissioning of the two lines, which will produce intermediate products for the automotive and aerospace industries, is scheduled for the second quarter of 2019. Andritz will supply the mechanical equipment, degreasing section and tension leveler for the continuous annealing line.
