Abstract:

Nowadays, the electric furnace equipment in general and the medium frequency induction furnace in particular are being widely applied for steel production. Power semiconductor induction steel furnaces have many outstanding advantages such as flexible control, fast response, economic efficiency, small size and volume, reliable working and high accuracy, especially applied the advances of other science and technology disciplines such as cybernetics, information technology in order to improve production efficiency, reduce the loss of energy, the cost of products and free labor. Therefore, the study of medium frequency induction furnace is essential. In which the issue of frequency control of the furnace while maintaining the head power is mentioned in this article. The paper suggests a solution to use PLC S7-200 controller of Siemens.
