Gasbarre Thermal Processing Systems manufactured and commissioned a humpback annealing furnace for a worldwide manufacturer and distributor of stainless steel sinks. The gas-fired, continuous furnace, which was custom-designed to meet the company’s strict process requirements, measured 106 feet long with a belt width of 32 inches. It is equipped with six heating zones that can heat up to 2200°F. The sink manufacturer wanted to increase production by up to 50%. A belt speed of 51 inches per minute was chosen to achieve that goal.
Andritz received an order from China’s Qinghai Zhuofeng New Material Co. Ltd. to supply two continuous annealing and processing lines, each with an annual capacity of 110,000 tons. Start-up is scheduled for the second quarter of 2021 (line 1) and the second quarter of 2022 (line 2). The lines will produce high-quality, flat aluminum product for the automotive industry. Andritz’s scope of supply also includes automation technology and commissioning.
Lindberg/MPH shipped a 2012°F (1100°C) crucible furnace to a research-and-development laboratory in the nuclear industry. The furnace will be used for laboratory melting applications including annealing, ashing, carbon firing, ceramic firing, hardening, nitriding, normalizing, sintering, solution treating and stress relieving. It is designed for use with a variety of crucibles, including alumina, mullite, quartz and metallic.
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. All required supplementary equipment, such as the hydraulic system, pressure-control system, water recooling system, emergency nitrogen supply connections and the complete electrical system, will be supplied by Ebner.
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.
