Other AbstractThe invention discloses a method and a device for controlling the planeness of a steel material. The method comprises: a rotary coder connected with a linear displacement servo motor is used for measuring actual linear displacement amount of a press wheel the rotary coder connected with a corner servo motor is used for measuring the actual corner of the press wheel a transducer inside the rotary coder converts a measured signal into a TTL square wave pulse and sends the TTL square wave pulse to a counting card the linear displacement and the corner are worked out through a computation program the control quantity of the displacement and the corner is converted to voltage value through an analog quantity output card and the voltage value is sent to a servo motor so that the center of the press wheel and the center of a steel material ventral shield are superposed to realize follow-up control of the press wheel. The device comprises the linear displacement servo motor, the corner servo motor, a screw rod, a supporting roller, the press wheel and a nut the screw rod is linked with the linear displacement servo motor and a press wheel bracket is provided with a guide shaft, a press oil cylinder, a base connecting rack, the press wheel, the corner servo motor, and the supporting roller which are linked with the press wheel bracket. The method and the device have the characteristics of high measuring precision, and the like.
