  • Patent number: 6383104
    Abstract: A device used to transfer and support articles during a high temperature heat treatment. The device is used to move articles into a heat treat furnace, hold the articles at an elevated temperature in a controlled atmosphere during the high temperature treatment and remove the articles from the furnace at the conclusion of the high temperature treatment, with no need to transfer the articles from the device. The device is comprised of a plurality of high temperature rollers, each roller including a roller bearing. A nonmetallic support surface capable of supporting the load of components undergoing the heat treatment is attached to the rollers. The device is designed to be nonreactive with either the furnace atmosphere or with the parts loaded onto it. The device also includes means to accommodate a temperature monitoring device such as a thermocouple to accurately monitor the temperature of the device during the thermal cycle.
