TAV Vacuum Furnaces supplied a vacuum furnace with rapid cooling in inert gas at high pressure to a company in the aviation industry. The furnace, which has useful dimensions of 400 mm (15.7 inches) wide x 400 mm (15.7 inches) high x 600 mm (23.6 inches) long and a maximum operating temperature of 2282°F (1250°C), is suited for hardening and annealing. An inert-gas circulation system combines high flow, high pressure and multidirectional flow distribution to ensure rapid and uniform cooling of the charge. The AMS 2750E-compliant furnace includes a SCADA supervisory system.
L&L Special Furnace Co. Inc. shipped a dual-chamber heat-treating furnace to a southeastern U.S. manufacturer of various items used in the production of heavy equipment and transportation devices. The box furnace will be used to heat treat the tooling used to manufacture these items. Its top chamber, which has an effective work zone of 16 inches wide x 16 inches high x 32 inches deep, is used to harden tool steels. Its bottom chamber, which has an effective work zone of 14 inches wide x 14 inches high x 32 inches deep, is used for tempering, stress relief and preheating.
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.
Gasbarre Furnace Group/J.L. Becker shipped a large-capacity gas-fired temper furnace to a specialty alloy manufacturer located in the northeast U.S. The furnace is designed to temper workloads after hardening. It is capable of processing workloads 32 feet wide x 6 feet long x 4 feet high that weigh up to 40,000 pounds. Temperature uniformity is achieved through five zones of heating, recirculation fans and a custom-designed baffling system. As a result, the furnace is capable of achieving ±10°F from 800°F to 1400°F.
Lucifer Furnaces delivered a large dual-chamber unit – a hardening furnace over a tempering oven – to a metal stamping manufacturer in the Midwest. The upper hardening chamber heats to 2300°F with 6.5 inches of multilayer insulation throughout the chamber. Heat is supplied through heavy-gauge, coil-wound wire elements in holders on the sides, back and door of the furnace. The lower-chamber tempering oven heats to a uniform 1200°F with a rear-mounted fan circulating air past the side-mounted heating elements.
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.
Can-Eng Furnaces International Ltd. has been contracted to design and commission a large-capacity fastener hardening system for a Tier 1 automotive supplier based in Detroit, Mich. The system closely integrates a computerized part-tracking and metering system, pre-washer, mesh-belt hardening furnace, oil-quench system, post-washer, temper furnace, soluble oil system, endothermic-gas generator and level 2 automation system. It is engineered to produce at a rated capacity of 6,000 pounds (2,700 kg) per hour.
Super Systems Inc. of Cincinnati, Ohio, completed a controls and software upgrade for JTEKT Corporation’s Koyo Bearings brand. The project will deliver more efficiencies through technology enhancements in the heat-treating operation at JTEKT’s Dahlonega, Ga., manufacturing facility. The scope of the investment includes all engineering, installation, controls and software for the company’s gas-fired hardening furnace line.
