Lindberg/MPH, Riverside, Mich., has shipped a Pacemaker integral quench furnace with an endothermic gas generator to a company in the die forging industry. The Pacemaker furnace has a maximum temperature rating of 1850°F and work chamber dimensions of 30x48x30 inches. The integral quench furnace system provides a total solution for the customer’s heat treating process.
The furnace utilizes a drive mechanism to push the workload into the furnace where it undergoes hardening under an endothermic gas atmosphere. A discharge drive system pushes the workload out of the furnace and onto a quench elevator. The load is then either lowered into an oil quench tank for fast cooling, or is elevated for a slower atmosphere cool. The endothermic gas generator system supplies the furnace atmosphere ,and features a gas mixing oxygen probe, touch screen displays, and gas to air cooler.
The furnace system is integrated into the customer’s present loading system. The furnace features fully automatic movement of the load, which is controlled through an advanced process controller with an HMI display. Equipment status screens are visible on the HMI screen. The controller also performs all data collection functions for process variables.
Atmosphere carbon potential is controlled with automatically adjusting flowmeters and an oxygen probe. Multiple burners fire through single-end radiant tubes to radiate heat onto the workload. Lindberg/MPH provided equipment installation supervision and equipment start-up, which was crried out by factory trained Lindberg/MPH technicians.
