Purpose. Automation of process control at installations for electron-beam remelting of titanium.
Application area. Metallurgy. Engineering.
Advantages. Compared with optical systems with a similar task, this video system has a high level of noise immunity from light reflections of electron beams, the effects of skull, strobe effect.
Description. Input of the image of the far edge of the mold into the computing device in video streaming mode. Video stream discretization into a sequence of photos (frames) for further processing. Sequential processing of photographs according to a given algorithm to select a parameter. Possibility of forming: emergency and warning signaling; diagnostic information; graph of changes in the level of molten metal over time on the monitor; databases on the history of bath level changes over time with a discretization period of not more than 1 s; control actions on the ingot lifting/pulling mechanism. Implementation of the human-machine interface of the video monitoring system for convenient operation of the operator.
