The products in the high-temperature kiln are placed on a plurality of horizontal refractory rollers with close intervals, and the products are conveyed from the kiln head to the kiln tail by the rotation of the rollers to finish the processes of preheating, heating, heat preservation and cooling. The furnace roller is kept stable only by the characteristics of the material at high temperature, which has higher requirements on the material performance. The furnace roller is generally longer, the radial rigidity is weaker, a workpiece with a heavier load can be bent and deformed after being operated for a long time in a high-temperature environment, the deformation of the middle part of the workpiece is particularly obvious, and the deformation of other parts of the workpiece can be caused by the problems of the position, the contact and the like of the workpiece. The furnace roller can not keep the same rotating frequency after being bent and deformed, so that the elevation of each roller way surface can not be on the same reference line, the load of each roller way is uneven, and great potential safety hazard exists.
