Improvements in sinter quality and productivity are achieved The OGS Operation Guidance System was developed by the Kawasaki Steel Corporation with the finality of achieving a stable permeability of the sinter bed with an optimal sinter quality water addition and sinter strand speed to control the BTP Improved Ignition Oven
Sinter Plants that produce iron ore sinter are important units in an integrated steel plant They face several operational challenges due to frequent changes in input raw materials the inability to instrument key equipment in the plant and the absence of real time sinter quality measurement To address these challenges Virtual Sinter® a digital twin of the
In this work sinter quality for improvement in gas permeability of blast furnace was investigated with reduction degradation and under load reduction tests As the results the reduction degradation of sinter is deteriorated by increasing H 2 concentration in the reduction gas
The comprehensive classification model of sinter quality and the regression model of sinter s total iron content were established by using various machine learning algorithms The results show
