Lucifer Furnaces delivered a bench-style box furnace for batch heat treating small loads of low-carbon steel to a parts manufacturer on the East Coast. The furnace, with 7 kW power, heats to 2200°F with easy-to-replace wire-wound heating elements in removable holders. A horizontal swing door seals the 12-inch-high x 14-inch-wide x 24-inch-long chamber, and a ceramic hearth plate supports the workload and protects the floor brick. The furnace is insulated with a combined 4.5 inches of lightweight hot-face firebrick insulation and cold-face mineral wool.
