Modernization of laboratory rolling mill 150 for the formation of students 'studies of automation object research

Studying the operation of automated control systems using computers significantly re-duces time, but does not give a complete picture system on real object. Therefore, use objects for study in educational process is appropriate and useful. The purpose to modernize laboratory rolling mill 150, designed lead, tin plasticine, equip it with sensors actuators. manual pressure device stand was replaced by an one, which worm gearbox additionally installed, allowed increase total gear ratio 94.5. thrust screws are moved from AC motor, controlled DOP-103BQ operator panel MS-300 frequency converter built-in PLC. As displacement sensor used photopulse PDF-3. installed equipment developed software PLC provided high accuracy in-stallation set position. Additionally, measure power parameters process: force electrical DC motor drive stand. allows you configure board, ie select type channels voltage signals, measurement ranges, signal color graph, polling frequency, number points display graph coordinate axes. In measurement, output signals monitor screen performed simultaneously. Before rolling, started keyboard or mouse change displayed time. At end process, stops, graphs parameter changes over time remain screen, quickly analyze process. results can be saved Excel file then viewed. stores: values those were measured. Measurement sizes rolled products before after determine stiffness metal, necessary calculate transmission coefficients tuning
