Lindberg/MPH shipped an integral-quench furnace with an endothermic gas generator to a company in the die forging industry. The furnace has a maximum temperature rating of 1850°F and work-chamber dimensions measuring 30 inches wide x 48 inches long x 30 inches high. The furnace utilizes a drive mechanism to push the workload into the furnace, where it undergoes a hardening process 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, circulated cooling or elevated for a slower atmosphere cool.
The endothermic gas generator system supplies the furnace atmosphere and features a gas-mixing oxygen probe, touchscreen displays and gas-to-air cooler. The integral-quench furnace, which is integrated into the company’s existing loading system, features fully automatic movement of the load within the furnace 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.
