Can-Eng Furnaces International Ltd. has been awarded a contract by a major U.S. automotive parts supplier for the complete overhaul and refurbishment of a cast link-belt normalizing furnace. Designed and manufactured by Can-Eng in 1996, the equipment was originally rated at 27,000 pounds/hour of hot-charged, closed-die forgings. It was known to be one of the largest cast link-belt furnaces in the world at the time of its manufacture. The refurbishment project will take place in Can-Eng’s Niagara Falls shops and will consist of a complete refractory reline, new combustion system, new control panel and a Level II automation system.

Gasbarre Thermal Processing Systems built and commissioned a high-temperature car-bottom furnace for a manufacturer of excavating equipment based in the southern U.S. The furnace has a work zone of 84 inches wide x 144 inches long x 48 inches high with a 16,000-pound load capacity and an operating temperature range of 1000-2282°F (538-1250°C). It will be used for stress relieving, normalizing and other high-temperature processes. The furnace, which replaced an existing furnace, gives the manufacturer improved operating efficiency and higher-temperature processing capabilities.

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.

Austria-based voestalpine Tubulars GmbH & Co. successfully commissioned a new heat-treatment line supplied by SMS group. Designed for seamless tubes with outside diameters between 60.3 and 273 mm (2.4 and 10.7 inches), it can process steel grades with alloying contents of up to approximately 20%. The line consists of a walking-beam-type austenitizing furnace, an SMS quenching head, a cooling table for normalizing, a tempering furnace, a cooling bed and two sawing stations for sample cutting. This equipment allows voestalpine Tubulars to perform heat treatments such as quenching, tempering and normalizing.

The rolling and thermal treatment of forged rings sometimes leaves residual stresses that cause dimensional distortion.

Since nearly all fasteners are heat treated, it is useful to understand the types of heat treatments used in the fastener industry.
