Abstract

There are defects in traditional liquid level control system of twin roll casting head-box, this study proposes one kind of liquid level precise control system for the head-box based on a combination of laser precise ranging and precise servo control system. Precise laser rangefinder implemented stable high-precision non-contact measurement of the molten aluminum level. A fast responsive and precise servo motion control system was constructed by linear slide module, AC servo driver and servo motion controller. The software of the servo control system for the liquid level was developed with a friendly human-machine interface, simplicity, efficiency, reliability by Delphi integrated development environment. The laboratory experiments and operations of the control system ensured rapid installation and commissioning on the production line. The system application shows that the control process is stable and reliable, and liquid level control error is not greater than ± 1.0mm.
