1.3.7 Electric control part of horizontal continuous casting line

Electric control part divide into power frequency electric furnace AC control part and auomatic control part:

• Power frequency electric furnace AC control part

(1) Melting furnace adopt three-phases. Output working pressure is 90~380V, eight gears to regulating voltage, noload stepness automatic coupling voltage regulator(three phases balance).

(2) Holding furnace use electromagnetic induction voltage regulator, can make load and stepless voltage regulating, it’s easy to control furnace temperature.

(3) the bottons and indictors are from shanghai, all the relay, switches are from famous factory.

b. Automatic control part

(1) Summation of the system

This part include main control PLC, human-machine interface, transducer, actuator, drive element and appurtenances

The horizontal continuous casting line use a SIEMENS PLC as the main controller, all of the transducer datas are access this PLC and all the actuators are controlled by the PLC. The datas after treatment by the PLC will be transferred to actuator and the actuator control the set’s running.

Through exchange datas between human-machine interface and PLC, all of the running state and running parameters can be adjusted.

This system has the following characteristic: use mature SIEMENS products and advanced control system, software developed by ourselves to make the equipment operated easily, the system stable and reliable, compatibility good; PLC main controller and human-machine interface separation layout, it can reduce artificial operation and disturbance for control center from the third part; cost moderate, mainantenance parts and extended parts complete and in plenty supply.

All the transducers and actuators are use high quality elements, the principle is stable, reliable, high precision, installation and mainantenance convenient and price moderate, drive element adopt AC servo system.

All of the electric control equipments are installed in a series of vertical type cabinets, possessing protection equipment and measure.

(2) Main controller

Main controller PLC adopt SIEMENS ,it can coordination with many machine and support external connect veries function extending devices.

(3) Holding furnace

Holding furnace include temperature test and temperature control, the test use a high temperature thermocouple accessed to temperature test module of main controller. Heating voltage and current are both through electric quantity transducer transferred to main controller PLC.

(4) Traction part

Use a set of AC servo electric machine from japan an’chuan, brushless servo amplifier and servo power supply to control running of the hollow bar, including the speed and time of pulling, stop and backward pushing.

Main controller PLC use serial data interface to control the system’s running.
