DIAGNOSIS OF THE ELECTRIC DRIVE OF THE DISCHARGE ROLLER CONVEYOR OF A WIDE-STRIP HOT MILL

Abstract. The purpose of the study is to develop an automated system for technical diagnostics state and regu-lation electric drive rollers collector roller table at a wide hot rolling mill based on change in load currents motors. allows quality finished rolled products produc-tivity be enhanced due timely detection faulty equipment its rapid replacement results diagnostics. following methods diverting possible malfunctions which can negatively affect were analyzed: experimental identification relation forms motors with specific types malfunctions; determination diagnostic signs values rollers; creation mathematical model calculating forces strip transportation; develop-ment algorithms charac-teristics development generalized algorithm operation system; evaluation effectiveness proposed operating mill. Analytical solving algebraic differential equations systems used study. As result research, developed diagnose eccentricity barrel table, malfunctioning brush-collector device motor, destruction couplings line, malfunc-tioning bearing units line or sides, correct alignment relative technological plane was experimentally confirmed. de-veloped create drives mills during their reconstruction, as well newly built mills. thus installed industrial plant's 2000
