Abstract
A hot walled, industrial, batch-type vacuum furnace constructed with a cylindrical furnace casing having a closed spherical end and an open end adapted to be closed by a sealable door. Furnace insulation is applied to the outside of the door and furnace casing so that the inside of the furnace is impervious to the furnace gases. Special mounting arrangements are used to seal furnace components extending into the casing as well as the door by elastomer seals which are air cooled.
