Abstract

The invention relates to the technical field of horizontal continuous caster control and particularly discloses an AC (alternating current) servo drive cast iron bar horizontal continuous caster control system. The system is characterized by comprising a PLC (programmable logic controller) and an AC servo system connected with the PLC, wherein the AC servo system is connected with an AC servo motor; the AC servo motor is connected with a speed reducer and a billet drawing roller; the AC servo motor and the PLC are connected through a photoelectric encoder; the photoelectric encoder is connected with the AC servo system; and the PLC is also connected with a touch screen. The system disclosed by the invention has the following advantages: the 131072P / r pulse of the servo motor is driven, the positioning accuracy of the system is high, control on uniform billet drawing step (the length of each billet drawing is consistent) is realized, and the billet drawing quality and the bar forming rate are improved. The control precision error of the drawing distance and reversing quantity does not exceed 0.1mm, and the pause time is controlled within 0.1s.

Description

technical field

[0001] The invention relates to the technical field of horizontal continuous casting machine control, in particular to an AC servo-driven horizontal continuous casting machine control system for cast iron profiles. Background technique

[0002] The driving system of cast iron horizontal continuous casting and the control accuracy of casting parameters are the key factors to ensure the further efficiency of cast iron horizontal continuous casting operation and the quality of casting. The quality of casting depends on the parameters related to casting speed (pull, push , stop time and drawing frequency, etc.), these controls require that the equipment can accurately execute the drawing action of the process design, and it is easy to adjust the process parameters suitable for each stage of the drawing process during the drawing process, especially the reproducibility and Synchronization of multi-roller servo drives.

[0003] At present, hydraulic servo or DC se...
