Pouring control with prediction of filling weight in tilting ladle type automatic pouring system

This paper presents an advanced control system in a tilting ladle type automatic pouring system. To improve the productivity and save energy, in the pouring process, it is important that the mould be filled precisely and quickly with molten metal. A sequence control employing prediction of filling weight is proposed in this paper. In the proposed control system, the sequence parameter varies depending on the predicted filling weight during the back tilting. The proposed control system has an advantage in that it can be performed by common control equipment such as a programmable logical controller. The effectiveness of the proposed filling weight control system is demonstrated through the experiments using water.
