Up in Connecticut, USA we see that Southwick & Meister Inc., a manufacturer of collets, bushings and cutting tools have ordered another small box furnace. The furnace comes from Lucifer Furnaces and will be used to heat treat under a nitrogen atmosphere. The 9-inch-high x 12-inch-wide x 18-inch-long chamber is lined with 5 inches of a combination of lightweight firebrick hot face backed with cold-face mineral wool for energy-efficient operation and low outside shell temperature. The furnace is fabricated from 10-gauge sheet steel reinforced with structural-steel members continuously welded to form a solid shell for operation with a positive flow of inert atmosphere.
