Abstract

The invention relates to the technical field of horizontal continuous casting machine control, and particularly discloses an AC servo driven cast iron profile horizontal continuous casting machine control system. The AC servo driven cast iron profile horizontal continuous casting machine control system is characterized by comprising a PLC controller and an AC servo system connected with the PLC controller, wherein the AC servo system is connected with an AC servo motor, and the AC servo motor is connected with a speed reducer and a billet drawing roller; the AC servo motor is connected with the PLC controller by means of a photoelectric encoder; and the photoelectric encoder is connected with the AC servo system, and a touch screen is connected to the PLC controller. The AC servo driven cast iron profile horizontal continuous casting machine control system has the advantages that: the 131072 P / r pulse of the servo motor is driven, the positioning precision of the system is high, control over uniform billet drawing step (the length of each billet drawing is consistent) is realized, and the billet drawing quality and the profile forming rate are improved. The control precision errorof the drawing distance and reversing quantity does not exceed 0.1 mm, and the pause time is controlled within 0.1 s.
