Pit Furnaces Heat Treat Auto Parts
Lindberg/MPH shipped two electrically heated pit furnaces to the automotive industry. The nitrogen atmosphere furnaces, which will be used to heat treat automotive parts, utilize high velocity forced convection heating systems inside an atmosphere-tight retort chamber. They have a maximum operating temperature of 1250°F (677°C) and a maximum load gross weight of 10,000 lb.
The atmosphere-tight furnace retorts are interior chambers that contain the nitrogen atmosphere and workload within a cylindrical shell that has a solid bottom and sealing trough at the top. The systems also include forced cooling systems to accelerate the furnace cooling cycle while the load is under nitrogen atmosphere and a Eurotherm programmable temperature controller.
