Lindberg/MPH announced the shipment of two gas-fired hardening and tempering furnaces to the manufacturing industry. These large-capacity box furnaces will be used for the normalizing, austenitizing, and tempering of forged components. The outer shell sidewalls and floor are constructed from 3/16” steel plate. The lining is ceramic fiber modules that store low amounts of heat and have superior insulating qualities, giving maximum fuel efficiency to the customer.

The doors are sealed by a ceramic gasket and lift vertically up to provide access to the work chamber. While closed, they are designed to provide a positive seal. The furnaces can accept a maximum load measuring 6’ wide by 6’ deep by 6’ high and the actual chamber is larger to provide clearance for parts.

“These furnaces have a robust combustion system which utilizes high velocity burners firing in an alternating high/low pattern. This air is provided by a 5 HP centrifugal pressure blower that includes a filter silencer. The customer’s specifications were met with these two furnaces and we were happy to customize them for the customer.”

- Bill St. Thomas, Business Development Manager
