The titaniferous blast furnace slag was selected as a kind of main raw material in the glass preparation. The glass system was separated phase into boron-rich phase and silicon-rich phase in Na2O-CaO-Al2O3-B2O3-SiO2-TiO2 system, and the changes of the two-phase composition after heat treated at different temperatures were studied. Results indicated that the network adjustment oxide existing in boron-rich phase was only CaO when phase separation temperature was below 750°C, and Na2O concentrated in silicon-rich phase. With the phase separation temperature rising, the distribution of Al2O3 and CaO was almost unchanged, whereas Na2O transferred from the silicon-rich phase to boron-rich phase gradually. In the phase separation process, TiO2 concentrated and crystallized on the phase separation interface.

The project aimed to develop and implement algorithms to diagnose the phase separation process based on digital images. The image processing techniques and various numerical methods for interpolation and integration were used to identify the process state. The swirl’s volume and diameters at its three different levels can be determined on-line. A consistent diagnostic signal is produced and can be used by the control unit. The program was written in Python using the OpenCV library that allows the analysis of digital images. The article presents the developed procedure that provides reliable results despite the poor quality of the input source video stream. The complete procedure was described with the results’ presentation and discussion at each step.
