Abstract
The invention provides a detecting and deviation rectifying method for a plate of a circular furnace. The detecting and deviation rectifying method includes steps of detecting the plate by details of drawing at least two straight lines passing through the original designed center point of the plate of the circular furnace and enabling the straight lines to intersect with an inner circular rail of the plate at detection points; measuring segment length from each detection point to the original designed center point; rectifying deviation of the plate if the measured segment lengths are different, and then calculating displacement of a centering device. A furnace bottom structure can be directly regulated quickly by regulating the centering device, the center of the furnace bottom structure can reset to the original theoretical designed center point by pushing the plate moves inwards or outwards according to the calculated value, and accordingly, normal running of the plate can be guaranteed.
