ABSTRACT:
A burn table suitable for supporting a workpiece during cutting is disclosed. The burn table comprises a fluid tank for providing a preselected fluid level and a bed of granular material, an upper surface of which supports a workpiece at a preselected distance from the level of the fluid. The granular material is diamagnetic and generally noncombustible. A chamber is in fluid communication with the fluid residing in the tank along with means for introducing into and exhausting from the chamber a gas. Raising or lowering the fluid level in the tank occurs by, respectively, introducing into or exhausting gas from the chamber. A guide rail attached to the tank and a smoothing bar are provided to screed or level the surface of the bed of granular material which supports the workpiece. In addition, the smoothing bar includes an electromagnet permitting slag formed during the cutting process to be removed during leveling of the granular material bed surface.
