  • Workpiece-carrier
    Patent number: 8708295
    Abstract: Improved workpiece-carrier in the form of a high-temperature-grating 10 assembled from mutually engaging elements consisting of carbon-fiber-reinforced carbon-composite-board-strips comprising comb-shaped elements, having a frame surrounding a horizontal grating as well as at least one workpiece-support (40) which is inert in relation to the supported workpiece and provides a workpiece-support-area (50) at a distance above the grating (3O)7 said work-piece-support (40) being arranged within at least one enclosing cut-out-section of at least one element wherein furthermore said elements comprise at least one element having interlocking cut-out-sections in alternating arrangement, at least one auxiliary element, said workpiece-support (40) is a single-piece part of high temperature ceramic of rod-shaped elongation being arranged parallel to the plane of said grating (30) and being an integral part of the grating by being enclosed beneath the workpiece-support-area (50) by cut-out-sections of a multitude of cros
