Lucifer Furnaces, Warrington, Pa., recently shipped a high-temperature laboratory box furnace to a leading producer of products for the battery, ceramics, and glass industries around the globe. Model 3027-K12 heats to 2500°F with silicon carbide rod-type heating elements mounted above and below the hearth providing uniform heat in the work chamber.
The 12 x 12 x 12-in. chamber is lined with 7 in. of insulation consisting of 5 in. insulating brick and 2 in. mineral wool block. The double pivot horizontal swing door with insulating plug meets with the throat section at the front of the furnace chamber minimizing heat loss. Hammond Lead Products, Pottstown, Pa. , selected a Honeywell UDC 3500 temperature controller with enhanced set point programming, fast scanning and onboard diagnostics, as well as an Overtemperature Safety System for automatic furnace shutdown in the event of a high temperature excursion, an add-on recommended for unattended furnace operation.
Controls are mounted in the furnace base cabinet and include a voltage-regulating power transformer with selector switches. A type R platinum thermocouple mounted through the roof provides a fast, accurate response and excellent lifespan at elevated temperatures. Hammond will be using the furnace for the development of PZT powders. Jon Hegland of Hammond says they chose a Lucifer because it was “the right product at the right price, and everyone involved in the sale were friendly and helpful.”
