Flat burning basin type supporting edge translation device

The invention discloses a flat burning basin type supporting edge translation device which comprises a movable supporting plate, a supporting plate horizontal plane, a movable platform, a rolling rod, a kiln pier, a kiln plate, a kiln plate horizontal plane, a basin body mud blank, a basin panel, a basin liner corner, a panel corner, a basin narrow edge and a basin liner. The bottom of the narrow edge of the basin is designed to be a movable supporting plate capable of translating, when a mud blank of the basin shrinks during high-temperature calcination, the distance generated when a blank body shrinks is achieved through horizontal displacement of the movable supporting plate, the movable supporting plate supports the narrow edge of the basin to move in a friction-free mode, and the whole edge of the narrow edge of the basin is supported by the movable supporting plate during shrinkage and achieves overall synchronous displacement. A moving surface is not generated between the basin narrow edge and the mova
