Abstract
A furnace is provided for continuous high-temperature heat processing in which a work product is conveyed through a furnace muffle by rectilinear beam motion. An inner and an outer beam are equipped with interleaved rods which are used to alternately lift the work product and advance it through the muffle. A continuous cycle of sequentially raising and advancing the rods attached to one beam, while lowering and retracting the rods of the other beam causes stepwise movement of the work product through the furnace. At no point in the cycle does the work product, rods, or beams make contact with the muffle, nor do the interleaved rods touch each other. The result is frictionless conveyance of the work product through the muffle which virtually eliminates particle generation.
