• Modeling of the hot metal silicon content in blast furnace

    2015-6-23 · As a highly complex multi-input and multi-output system blast furnace plays an important role in industrial development. Although much research has been done in the past few decades there still exist many problems to be solved such as the modeling problem. This paper adopts support vector regression (SVR) to construct the prediction model of blast furnace silicon content.
