Lindberg/MPH ships aluminum melting and holding furnace

Lindberg/MPH, Mich., has announced the shipment of a gas-fired reverberatory aluminum melting and holding furnace equipped with a preheat hearth. The furnace, designed for manufacturing aluminum parts, boasts a melt rate of 10,000 pounds per hour and a maximum temperature rating of 1450°F. It has a holding capacity of 85,000 pounds, based on 155 pounds per cubic foot of molten aluminum.

The furnace features a vertically rising air-operated door for loading the preheat hearth and a full-width cleanout door at the rear for unloading. Designed with an elevated base, it includes a bottom-mounted magnetic stirring mechanism and an air pressure pump well for dispensing molten aluminum. This configuration allows the furnace to remain idle for extended periods without significant temperature variation.

Temperature control is managed by three controllers, while flame supervision equipment ensures safety, including forced-air purging and automatic shutdown in case of system failures.

One Minute Mentor: Improving the Homogeneity of the Distortion Behavior

Controlling out-of-roundness is important for certain precision applications, such as class C and D cutting hobs made of high-speed steels. Class C and D hobs must be held close to size limits because they are not ground to size after heat treatment, but rather are used in the unground condition.

Normal size distortion in hardening and tempering can be accommodated by making the tool slightly oversize or slightly undersize, as required, before heat treating. High-speed steel bars, however, have been observed to go out-of-round as much as 0.05 mm (0.002 in.) during heat treatment. The pattern of size distortion shown in Fig. 8 can occur. It appears to be related to the initial shape of the cast ingot and to the specific primary-mill processing used to reduce the ingot into bars.

Wisconsin Oven ships small batch oven to Canadian manufacturer

Wisconsin Oven, East Troy, WI, announced the international shipment of an electrically heated small batch oven to a Canadian manufacturer of automotive components. The oven, designed for curing parts, has a maximum temperature rating of 650°F and chamber dimensions of 4’ W x 4’ L x 4’ H. Prior to shipment, the oven’s temperature uniformity of ± 10°F was verified through a nine-point profile test conducted in an empty chamber under static conditions.

The unit features patented high-efficiency panel seams for improved insulation, a 4” thick insulated floor, and two carbon steel shelves for part loading, each rated for 5 pounds per square foot. It utilizes combination airflow for optimal heating rates and uniformity, with temperature controlled by a Watlow F4T digital controller, featuring a touch screen, PID control, and Ethernet communication.

The oven also includes a process timer with an audible alarm, ensuring consistent curing and part quality.

Constellium announces significant weight savings in EV Battery enclosures through ALIVE project

Constellium, based in Paris, announced that its collaborative research project, Aluminium Intensive Vehicle Enclosures (ALIVE), has achieved weight savings of 12 to 35 percent for electric vehicle (EV) battery enclosures. The project, led by Constellium’s University Technology Center at Brunel University London, focused on optimizing the design and manufacturing processes for structural aluminum enclosures in EVs.

Launched in 2020, the £15 million initiative was partially funded by the UK government through the Advanced Propulsion Centre (APC). The project involved six industrial partners, including BMW, Volvo, and Innoval Technology, along with university technology partners from Brunel University London and the University of Warwick.

The ALIVE team developed new aluminum designs using Constellium’s high-strength alloys, HSA6® and HCA6®, while implementing advanced joining and forming technologies. Full-scale prototypes were produced and successfully passed rigorous testing for performance, safety, and fire resistance. The project also generated cost models to support future industrialization of the designs.

OMM: Material aspects of Distortion

Size distortion in ledeburitic cold-work tool steels is always higher in longitudinal direction (the direction of main deformation, which is the direction of the elongated carbide stringers). The figure shows the effect in three different cases. 

If plates for cutting tools made from ledeburitic cold-work tool steels are taken from small bar materials in the longitudinal direction, the main direction of distortion will also be in the longitudinal direction of the plate (case I). If the same plate is taken in the transverse direction from a wide bar material, the main direction of distortion will be in the transverse direction of the plate (case II). Finally, if the plate is taken as a slice from a large-cross-section thick bar, the carbide orientation and the main direction of distortion will be in the direction of the plate thickness (case III).
