Can-Eng Furnaces International Ltd. received an order from Oregon Products to design and commission a continuous mesh-belt austemper heat-treatment system. The high-capacity system integrates a computerized loading system, pre-wash system, atmosphere-controlled mesh-belt austenitizing furnace, molten salt quench conveyor system, post-quench residual salt removal and recycling system, mesh-belt parts drying oven and unloading system. It also includes Can-Eng’s PET system, which provides individual lot/product traceability, detailed process data collection for continuous process improvements and comprehensive Industry 4.0 equipment diagnostics capability.
Extractive metallurgy is an area of our science that deals with the process and methods of gathering and isolating metals from their ores (i.e., natural mineral deposits) and in some instances refining them.
Fives received two contracts to design and supply reheating furnaces to Chinese steelmakers, both with strict requirements on energy consumption and NOx emissions. The first project covers an ultra-low-NOx furnace to reheat long products, such as stainless steel bars, coils or wires, for Yantai Walsin Stainless Steel. Fives will supply a walking-beam furnace with a capacity of 85 tons per hour. The second contract was signed with Shijiazhuang Iron & Steel Company within China’s HBIS Group for two reheating furnaces, each with a production capacity of 130 tons per hour.
Gasbarre Thermal Processing Systems commissioned a 48-inch-wide belt annealing furnace for a global manufacturer. The furnace is equipped with three heating zones that can heat up to 1200°F (650°C). The company required a target belt speed of 10 inches per minute and 2,000 pounds per hour, which were achieved. To aid with unattended loading and offloading, Gasbarre designed a special automated parts feeder and a pneumatic unload mechanism. The furnace also includes an Allen-Bradley PanelView HMI for complete furnace control and data tracking and trending.
Premier Furnace Specialists and BeaverMatic completed a $2.5 million building expansion at one of its Farmington Hills, Mich., facilities. The expansion provides 45-foot-high ceilings with two (25-ton and 10-ton) overhead cranes to complement the existing two 10-ton overhead cranes. The total square feet under one roof is now 40,000. The expansion was needed for the continued growth of both companies and to accommodate the magnitude of the furnaces being built. The companies intend to hire additional employees in the future.
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.
Magnetic Specialties Inc. (MSI) built a new 4,800-square-foot addition to its facility in Telford, Pa. The insulated and heated steel building with a reinforced concrete floor will increase production floor space by 25-30%. MSI manufactures heavy-duty power supplies for the electric furnace industry; specialty transformers and reactors for a range of industries; and smaller specialty transformers for the electronics industry.
Allison Transmission Holdings Inc., a global manufacturer of medium- and heavy-duty fully automatic transmissions, acquired the assets and certain liabilities of Walker Die Casting and C&R Tool and Engineering for approximately $103 million. Lewisburg, Tenn.-based Walker produces aluminum castings and supplies essential components for Allison’s core on-highway transmission products. Muscle Shoals, Ala.-based C&R Tool and Engineering supplies metalworking tools for use at Walker and other companies.
Nitrex Metal Inc. supplied a nitriding system to Hydro Extruded Solutions in Trzcianka, Poland, to address the company’s need for improved process performance and more accurate control of nitriding results. The nitriding system replaces a decommissioned nitrider that was phased out several years ago due to extrusion die failures and inconsistent metallurgical results. It includes Nitreg technology that helps optimize parameters for maximum efficiency and quality and increase die strength and extrusion throughput while reducing the possibility of potential die failures.
