Beschreibung
Zusammenfassung:	The invention discloses a slab head warping and buckling control method considering rolling specification changes. The method comprises the following steps that S1, current pass technological parameters of a slab of the current rolling specification are obtained on a production site; s2, calculating a current-pass template sled coefficient of the plate blank of the current rolling specification; s3, on a production site, after the rolling specification of the plate blank is changed, current pass technological parameters of the plate blank after the specification is changed are obtained; s4, calculating a current pass template sled coefficient of the plate blank after the specification is changed; s5, calculating the sled coefficient of the current pass of the plate blank after the specification is changed; and S6, the sled coefficient of the current pass of the plate blank after specification change is issued to a rolling basic automatic control system, the roller speed value is calculated and used for the fi
