Title:
SLAB SURFACE MAINTENANCE METHOD
Document Type and Number:
WIPO Patent Application WO/2020/213206
Kind Code:
A1
Abstract:
Provided is a slab surface maintenance method whereby it is possible to reliably cut and remove slab surface defects while minimizing the amount of cutting and the number of cutting tool strokes. When using a cutting tool that is equipped with a cutting edge on the outer circumference of a cylindrical body and that rotates about the cylinder axis to cut the side surface of a slab placed on a bed by moving the cutting tool along the longitudinal direction of the slab, at each position x set at predetermined intervals in the longitudinal direction of the slab side surface, a minimum cutting amount, which is the minimum amount of cutting required for surface maintenance, is set in advance as the cutting amount for each of a plurality of locations in the height direction of the slab side surface, and the cutting tool cutting position is determined and the cutting tool travel path is controlled so that at each position x, the cutting amount at each of the plurality of locations in the height direction is at least the minimum cutting amount and so that the cross-sectional area removed by cutting with the cutting tool is the minimum amount or is close to the minimum amount.
