L&L Commissions High-Temperature Box Furnace for Ceramic Composite Parts

L&L Special Furnace Company, Inc. has shipped and commissioned a large high-temperature box furnace to a Midwestern U.S. plant starting production on ceramic matrix parts that will be used in military and aerospace applications.

The L&L GHH3350 has an effective work zone of 32” wide by 30” high by 50” deep. The furnace is capable of reaching temperatures up to 1,700°C / 3,100°F under partial atmospheric pressure. There is also a vacuum pump to help remove oxygen prior to beginning the thermal cycle.

The front-loading box furnace is insulated with multi-layer, high-temperature insulation. The floor is reinforced and includes a composite hearth capable of supporting load weights up to 500 pounds.

The GHH3350 is heated with molybdenum disilicide elements located on the side walls and back. It is controlled by a Eurotherm program control with overtemperature protection and includes a multi-pen chart recorder with 36 inputs to record various temperatures, flow rates and pressures.

The case is sealed for use with inert atmosphere. It includes an automated flow panel, type B thermocouples, and a stack light audible visual annunciator system. The furnace has an afterburner or scrubber to remove any contaminates prior to evacuation from the furnace.

All L&L furnaces can be configured with various options and be specifically tailored to meet your thermal needs. L&L also offers furnaces equipped with pyrometry packages to meet ASM2750.

Options include a variety of control and recorder configurations. A three-day, all-inclusive startup service is included with each system within the continental U.S. and Canada. International startup and training service is available by factory quote.

If precise temperature control and uniformity is key to your process, then L&L's GHH or GHE series is a great choice. Please be sure to visit our website at www.llfurnace.com.
