Lindberg/MPH shipped an electrically heated, large-chamber utility box furnace to an automotive-parts supplier. The furnace will be used for batch testing aluminum castings on a daily basis at a temperature of 932°F (500°C). Work-chamber dimensions are 24 inches wide x 24 inches deep x 24 inches high. The furnace utilizes vacuum-formed ceramic-fiber insulation with low heat loss for operating economy and minimum heat storage, which results in rapid heat-up and control response.
To ensure even less heat loss, a double steel shell construction is used to create a low-temperature outer surface. The insulation and heating elements maintain uniform heat distribution for an energy-efficient design. The furnace’s maximum temperature rating is 2012°F (1100°C).
