Steel coil feeding method and device for hot rolling temper mill

The invention discloses a steel coil feeding method for a hot rolling temper mill. The method comprises the steps that a hot rolling production and manufacturing execution system obtains a temper production plan of a temper mill; the hot rolling production and manufacturing execution system sends a hoisting instruction to a crown block control system; the crown block control system hoists an ith steel coil to an ith saddle according to the hoisting instruction; the crown block control system acquires the information of the ith saddle corresponding to the ith steel coil; the crown block controlsystem sends a feeding message instruction of the ith steel coil to the hot rolling production and manufacturing execution system, wherein the feeding message instruction comprises feeding message information of the ith steel coil; the hot rolling production and manufacturing system sends the feeding message information of the ith steel coil to a leveling secondary system according to the feedingmessage instruction; and
