Abstract
An edging method including changing an incident angle of a slab with respect to a pair of edging members that are disposed on a conveyance line of the slab and that edge the slab based on information relating to the slab acquired at at least one of prior to edging or after edging.
Claims3
An edging method comprising changing an incident angle of a slab having a width direction across its width with respect to a pair of edging units that are disposed on a conveyance line of the slab and that edge the slab based on information relating to the slab acquired at at least one of prior to edging or after edging, wherein:
- the information includes
- (i) a temperature distribution across the width direction of the slab prior to edging, or
- (ii) a slab thickness variation across the width direction of the slab at at least one of prior to edging or after edging, or
- (iii) a variation between coefficients of friction of both lateral faces of the slab, which are separated by the width direction of the slab, with respect to the edging units prior to edging;
- and
- the incident angle of the slab is changed according to the temperature distribution, the slab thickness variation, or the variation between the coefficients of friction.
