Lindberg/MPH Ships Atmosphere Box Furnace to the Steel and Mining Industry

Press release date: Jul 26, 2017

July 26, 2017 - Lindberg/MPH announced the shipment of an electrically heated, rod over-bend atmosphere box furnace to the steel and mining industry. This is the second heat treating furnace of this kind that the customer has ordered from Lindberg/MPH. It is designed to meet the customer’s specific process based on the previous existing model they had ordered.

The atmosphere box furnace has work chamber dimensions of 15”W x 30”D x 12” H and a maximum temperature rating of 2000°F. The furnace is constructed with a gas tight steel shell made from continuous welded steel plate reinforced with structural steel members.

The furnace door lifts up to provide access to the work chamber and is sealed by metal to metal contact to eliminate gasket wear and maintenance. The door is raised and lowered by an air cylinder with roller chain. A natural gas flame curtain is provided for the door area and is activated when the front door is opened to ignite exiting combustible atmosphere and minimize air infiltration back into the purge chamber. The furnace chamber is heated with a radiant heating system.

The atmosphere system includes a nitrogen flow meter, hydrogen flow meter, argon flow meter, CO flow meter, and CO2 flow meter. An atmosphere saturator allows variation of the moisture dew point of the nitrogen that is flowing to the furnace chamber. The saturator tank is fabricated of 304 Stainless Steel. The dew point is controlled from a dew point transmitter located in the nitrogen atmosphere line before entering the furnace chamber. Dew point is also monitored through a sample port located in the side of the furnace chamber.

“At Lindberg/MPH we pride ourselves on having the experience to design our equipment to meet the most stringent requirements. This customer’s process required the furnace to provide six different gas atmospheres. This is the second system we have shipped to them with this advanced atmosphere system.”- Kelley Shreve, Sales Representative
