Accurate process control through automation is the key to achieving efficient and stable operation of a blast furnace. In this study, we developed an automatic system hot metal temperature (HMT). To cope with slow complex dynamics furnace, constructed algorithm that predicts eight-hour-ahead HMT using two-dimensional (2D) transient model calculates optimal target pulverized coal ratio (PCR) flo...

Blast-furnace slag is one of the main by-products produced in process blast-furnace ironmaking. Its metallurgical properties have an important impact on smooth operation and long life blast furnaces. In this paper, activity MgO a CaO-SiO2-MgO-Al2O3 quaternary system was measured using reference-slag method at 1773–1873 K. The effects temperature coefficient Mg Sn were discussed. results showed ...
