4.1 tension control in normal operation up ray machine reverse imposed on the constant torque, drag tension round forward, line up at the plane and tension between rounds (plus heat furnace) on the wire by a certain tension, help ra**e steel wire mechanical properties. 4.2 line of stat**tics in some projects, the length of a roll of steel h**e more stringent requirements according to production set for the long lines, following formula ~ 50 ~ wk a round r tension tension round will speed encoder feedback signals to the converter application of dcs 400. application of dcs 400 from the output signal to a plc analog input module, tension was after round of the tension wheel speed. at circle time interrupted by ob35 h**e. the method has the advantages of no additional hardware to measure the long lines, high accuracy. 4.3 speed control speed control essentially need to consider the following points : on or after shearing, low-speed increased from the normal operation of the high speed; normal or shear between stands by the low speed to high speed. adm**sion ray machine speed control. in order to ensure the appearance of product formation, standardized requirements wire from the inside out would circle out, circle drive to remain in the frame. when the tension wheel rotational speed, or operation of the system will speed line, for the resumption of wire diameter, the ever changing needs of the resumption ray machine speed. 4.4 temperature control stability of processed, the outlet temperature wire directly determines the products, technical indicators, therefore the heating temperature control of the entire system design focus. (1) feedforward control as a result of system operation speed of the line often changes when the furnace output unchanged. wire up the furnace temperature change. to maintain the wire outlet temperature constant, the introduction of static feedforward control. algorithm are as follows : static energy balance equation (t0) at=ckv (t0) at[t. (t0) ti (t0)] - p (t0) --t0 moment if furnace output diao -- efficiency c - - steel heat capacity and k unit length of the wire quality (t0) -- £ 0 times the speed steel ti (t 0) -- 0 £ moment vi wire furnace temperature t. (t0) -- £ 0 moment wire outlet temperature static feedforward control equation p (t) = ck (t) copper ( t) ti (t)] (2) feedback control due to the following reasons just use (to no. 53) plc-based automatic harmonic analys** of leak detection devices' electrical technology in the magazine "2003, a voltage integrated circuits and devices of the power supply voltage, the power supply module designed for symmetric output 15v dc power supply. ± in addition, the devices are under some circumstances to take a corresponding anti-interference and protection measures. 3.3 device software installation software language used ladder, by the programming device or computer via cable transm**sion plc debugging and run. when the need to amend the procedure, only by the programmer to amend some modifications, can be installed by the new requirements, procedures modifying and debugging simple and flexible, ** very conducive to the technical staff in the grassroots. 4 conclusion practice has proved that the device ** common, 6~63kv apply to the neutral mode of operation of the system; alignment ** accurate, reliable and strong anti-interference; program design and modify simple; use all modules, the structure design, easy installation, very suitable for primary use of technology, popular corporate users welcome. 20210311
