CONTROL OF TRANSPORT AND FINISHING LINES oxygen-converter shop

摘要

The invention relates to the field of control of electric transport and finishing lines steelworks and can be used in different sections of the control circuits roller conveyors. Technical Problem - reducing emergency downtime and increase metal production by work stable transport and finishing lines. Control unit freight finishing lines BOF shop includes serially connected drive control system, complete thyristor actuator, protection and alarm systems and motors constant of the actuator current, and also series-connected three-phase transformer, three-phase diode rectifiers and a relay portion, and the latter output is connected with excitation windings actuator DC motors and one of the system output drive control is coupled to one input of a relay portion, 1 Fig.
