Can-Eng Furnaces International Ltd. has been contracted to engineer and commission a continuous quench-and-temper furnace system for a North American manufacturer of mining, construction and material-handling products. This equipment will be part of an automated manufacturing cell and will be fed automatically from upstream handling equipment. Special considerations have been made to precisely control the quench temperature to reduce hardness variations and improve overall part quality. The multi-zone belt-style temper furnace employs high-efficiency, natural-gas-fired heating and recirculation systems, which have been proven to provide superior temperature uniformity in demanding applications. Can-Eng’s engineered control system, which controls and monitors the equipment, utilizes an Allen Bradly PLC and HMI.
Can-Eng Furnaces International Ltd. received the final acceptance certificate from Indian steelmaker SAIL for a roller-hearth plate quench-and-temper system. It is designed to heat treat a wide range of plates from 0.25-4.0 inches (6-100 mm) thick x 118 inches (3,000 mm) wide up to 42.5 feet (13 meters) long in a variety of grades for commercial and non-commercial applications. With an overall line length of 400 feet (122 meters) and a restrained roller spray quench at the heart of the system, the heat-treatment process results in true flat plates with metallurgical properties that exceed contractual requirements. The auto-recuperative radiant-tube-fired atmosphere roller-hearth hardening furnace and direct-fired temper furnace run off coke-oven gas (COG), a byproduct of the steelmaking process.
Nucor Steel has chosen Danieli to supply a new quenching and self-tempering system to be installed at its mill in Marion, Ohio. The quenching and self-tempering process improves the mechanical properties of deformed bars, particularly yield strength, using billets with lower alloy content. The result is a product with final technological characteristics equal to or better than those obtained by low-alloyed/micro-alloyed steels.
Premier Thermal Solutions is increasing oil quench-and-temper capacity at its Atmosphere Annealing Mt. Hope facility in Lansing, Mich. Through the enhancement of an existing roller-hearth tray furnace, the facility will double its oil-quench capacity. The additional capacity is in response to increasing demand seen from many of the industries that Atmosphere Annealing serves, including automotive, energy, heavy equipment, heavy truck and rail. The furnace will be online in the first quarter of 2019.
The new advanced quench-and-temper facility (AQTF) heat-treatment line supplied by SMS group to TimkenSteel at its Gambrinus Steel Plant in Canton, Ohio, commenced full commercial production. Extensive testing was successfully completed in November 2017. The line is able to treat 10 tons per hour of bars and heavy-walled tubes up to 13 inches in diameter.
TimkenSteel brought its newest heat-treatment asset, an advanced quench-and-temper facility, online and has started processing customer orders. The addition of the $40 million facility, located at the company's Gambrinus Steel Plant in Canton, Ohio, increases TimkenSteel's existing quench-and-temper capacity by 50,000 tons, or 45%, and brings the company's total annual heat-treatment capacity to 500,000 process tons. According to TimkenSteel, it is the largest of its four heat-treatment facilities.
