Silicon steel hot rolling plate edge optimizing method

The invention relates to the technical field of rolling and in particular relates to a silicon steel hot rolling plate edge optimizing method. The method comprises steps of setting on-off of a sensing heater, setting a maximum value in an adjustable range of an opening degree (Gap) value of the sensing heater corresponding to a head part, a middle part and a tail part of an intermediate billet; setting a start of the sensing heater, sensing an opening (Gap) value of the head part of the intermediate billet corresponding to the sensing heater as H1+10mm, L+30mm and H2+10mm, setting on-off of the sensing heater, setting an maximum value in an adjustable range of an opening degree (Gap) value of the sensing heater corresponding to the head part, the middle part and the tail part of the intermediate billet; setting the start of the sensing heater, and setting an opening (Gap) value of the head part, the middle part and the tail part of the intermediate billet corresponding to sensing heater as H1+10mm, L+30mm and H2+10mm. The silicon steel hot rolling plate edge optimizing method solves a technical problem of difficulty in control of the edge drop of the silicon steel hot rolling plate in the prior art, so the edge drop of the silicon steel hot rolling can be reduced.
