FAR INFRARED HEATING FURNACE FOR STEEL PLATE FOR HOT PRESSING

摘要

The present invention provides a far infrared heating furnace for a steel plate for hot pressing wherein thermal deformation of the furnace body and various parts of the furnace body is suppressed. A far infrared heating furnace (10) is provided with: heating units (13-1 - 13-6) and a roof unit (19) having blocks formed from thermal insulation material and disposed encompassing a space for accommodating a steel plate for hot pressing in a horizontal plane, and far infrared radiation heaters disposed above and below the steel plate for hot pressing for heating the steel plate for hot pressing; and a steel furnace body frame (12) disposed surrounding the heating units and roof unit. The furnace body frame is provided with spacers (17-1 - 17-7) for separating and supporting the heating units and roof unit from the furnace body frame.
