Abstract
A slot furnace has a radiation resistant door which can easily be opened and closed as necessary during operation. The door is mounted on a pivot so that an end thereof covered with heat resistant insulation can be pivoted to open and close the slot when desired, to allow ease of feeding and removing materials from the furnace while preventing substantial radiational heat loss during normal operations.
