Multi-furnace heat treat project for major steel forger

Nutec Bickley, Mexico, has been awarded a contract to manufacture and install five new lift-up furnaces, along with a fully modernized combustion system, for a leading U.S. manufacturer of high-quality alloy steel and carbon steel closed-die forgings. The project will take place between May and December 2023, with onsite work completed one furnace at a time to ensure the customer’s production schedules are not impacted. Two of the new furnaces will be used for tempering, while the remaining three will be used for austenitizing. Each furnace will be fitted with the latest control systems, complete fiber flues, and new exhaust and pressure control systems, along with insulation.

Nutec Bickley’s state-of-the-art combustion packages will be fully compliant with NFPA 86 standards, incorporating a fuel-only control system to allow maximum temperature uniformity potential for all cycles. The retrofitted furnaces will benefit from high-velocity nozzle mixing burners fitted with high-temperature burner blocks. The combustion systems will also feature automatic air control valves to adjust the maximum air volume used and to ensure proper burner ignition conditions.

The project will involve careful teamwork between the customer and Nutec Bickley to ensure successful delivery and highest quality outcomes. Rodrigo González, VP Metals at Nutec Bickley, emphasized the importance of constant communication and status updates with customers for a dynamic and mutually beneficial project result.

Wisconsin oven ships pin conveyor oven to automotive manufacturer

Wisconsin Oven Corp., East Troy, has shipped one electrically heated conveyor oven to an automotive manufacturer, which will be used for tempering automotive parts. The conveyor oven features a chain style conveyor system with vertical pins, ensuring the uniform transfer of parts through the heating and cooldown zones of the oven. The maximum temperature rating of the conveyor oven is 260° C, with interior chamber dimensions of 3’6” W x 20’10” L x 9” H.

The conveyor oven also features a top-down bottom-up airflow configuration designed with a 55,000 CFM @ 50 HP blower, ensuring optimal temperature uniformity of ±2.5° C at 163°C, documented with a temperature uniformity test. The oven is equipped with a continuous chain conveyor with vertical pins, programmable temperature controller, and recorder with Ethernet capabilities.

The unique features of this tempering oven include the ability to automatically scan the parts while being loaded onto the conveyor and validate that the correct part is being loaded, providing a pass/fail regarding heating time and temperature. The conveyor oven also includes an ambient cooldown zone and supervised installation with start-up and training.

Mike Grande, vice president of sales,said that, “Our continuous designs provide customers with innovative solutions to meet their load and process requirements. This conveyor oven was designed with high-velocity impingement air nozzles for rapid, uniform heating and optimal part results.” The equipment was fully factory tested and adjusted prior to shipment from the facility, ensuring it met all Wisconsin Oven quality standards. The equipment comes with a 2-year warranty, providing peace of mind for the automotive manufacturer.
