ABSTRACT:
A high temperature box annealing furnace for metallic coil annealing practices. The furnace comprises a fixed base and a removable bell capable of achieving a sealed relationship with the base. The interior of the bell side walls, end walls and roof are lined with ceramic fiber insulation and are provided with electrical resistance heating elements. The heating elements are divided into at least two separately controllable zones, a first zone including the heating elements mounted on the bell roof and the upper portions of the bell side and end walls and a second zone including the heating elements mounted on the lower portion of the bell side and end walls. The base comprises a steel framework supporting a cast refractory base member configured to support one or more coils. Each coil is provided with a cover and the cast refractory base member provides a sand seal for the lower edge of the covers. The cast refractory base has an atmosphere inlet for each coil positioned at the center or eye of the coil. Cooling capacity for the furnace is provided by inlets and outlets for an appropriate cooling gas.
