Apparatus is provided for heating powder material charges to high temperatures at a fast rate, and for moving the charges through process operations, and for maintaining the temperatures of preheated charges and protecting the charges against contamination as they are moved through process operations. Such apparatus includes: a charge enclosing heated enclosure body having two or more separate sections; an internal wall in the enclosure body sections that has an internal cavity having a configuration shaped to hold a desired charge configuration; heating means for the internal cavity wall to heat it to desired temperature. Apparatus is also provided for heating metal, ceramic and similar material charges to high temperatures at a fast rate, and for moving the charges through heating and process operations, and for controlling the temperatures of preheated charges and protecting the charges against contamination as they are moved through process operations. Such apparatus includes additional structure and improvements producing substantial advantages for heating and processing an increased range of material and product forms. The additional structure and improvements include: improved structure for entering charges into a heating system with minimum loss from the system of protective gas atmosphere, and with minimum atmosphere contamination; novel structure for discharging heated charges under controlled conditions from a heating system with minimum loss of protective gas atmosphere; mechanisms for handling multiple products to increase the production capacity of a system; and apparatus for conveniently changing heating and handling components in a system to allow efficient production operations with a variety of product forms.
