MODERNIZATION OF LABORATORY ROLLING MILL 150 FOR THE FORMATION OF STUDENTS 'STUDIES OF AUTOMATION OBJECT RESEARCH.

Abstract

It was fulfilled laboratory rolling mill 150 reconstruction for student’s investigation of rolling mill as automation object. For remote control screw down movement was mounted screw down auxiliary reductor with AC motor, screw down encoder, load cells, inverter with built-in PLC MS-300 and touch panel HMI DOP-103BQ. It was developed PLC and touch panel HMI software for control screw down movement. Software touch panel HMI provide with set point adjustment screw down movement and actual distance monitoring. Software inverter with built-in PLC MS-300 exercise control screw down movement and stopping in position set point without rundown. It was developed software for investigation of rolling force and electrical data’s of mill motor. Software provides measurement and memory of data’s and on-line graphic display. Measurement of rolling force and rolled metal thickness provides ability to build stand stiffness and rolled metal stiffness.
