SH2500/8-255/12

1. Brief Introduction
This production line can produce low oxygen bright copper rod of ф8mm. It is composed of reverberatory, furnace six-wheel continuous casting machine, forward hauling, shearer, straightening machine, chamfering machine, brushing machine, Ingot conveyor, continuous rolling mill, backward hauling, continuous rod coiler device etc.

In this electrical system of continuous casting and rolling production line, transmission motor for casting machine, transmission motor for forward hauling, transmission motor for shearer, transmission motor for coiler, adopt frequency speed controller, brand “Siemens”, MM series; transmission motor for rolling mill adopts DC converter, Siemens, 6RA28 series (Additional 1200A SCR power unit).

All speed control device should be operated by operating components of operating desk or HMI touch screen of main operating platform through PLC of OMRON-CQM1H series, transmission controlling by the way of RS485 main line communication.

There are two controlling ways: single machine, linkage machine. When the single machine runs, the speed of each transmission motor can be set separately; under the linkage controlling ways, the speed of casting, forward hauling, rolling mill, backward hauling, coiler transmission motor, should by the motor of casting machine for standard. The speed of forward hauling, rolling mill motor follow the casting machine according to the wire speed; the speed of backward hauling motor follows the rolling mill according to the wire speed; the speed of coiler motor follows backward hauling ( every motor have linkage adjustable speed device); shearer, right and left transfers fence operated by the single machine. Every transmission motors’ speed in the whole line controlled by the way of “speed chain”, it advanced the operation become more simple and easy to master.
