Ground Granulated Blast Furnace Slag

1. Ground Granulated Blast Furnace Slag Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. Blast furnace slag is defined as “the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a blast furnace.” [1] In the production of iron, blast furnaces are loaded with iron o...

Using Non-linear Garch Model to Predict Silicon Content in Blast Furnace Hot Metal

Forecasting of silicon content in blast furnace (BF) hot metal has always been an important tool in the control of iron-making process. To get an accurate prediction of silicon content is an urgent task for BF operators. The approach based on generalized autoregressive conditional heteroskedastic (GARCH) has been introduced to predict step-ahead silicon content in BF hot metal. The algorithm ha...

Using Genetic Algorithms as a Controller for Hot Metal Temperature in Blast Furnace Processes

The hot metal temperature (HMT) of a blast furnace is an important indicator of the furnace’s internal state. Because the blast furnace system is non-linear, neural networks have been employed to approximate these systems. Artificial neural nets have been developed to approximate these dynamics and predict future HMT hours into the future, with limited accuracy. This paper focuses on inversion,...

Java-based Integrating Simulator for Blast Furnace

The method of integrating many partial simulators for a complicated system in the consideration of interaction is proposed. Java Native Interface is used to integrate the simulators programmed in different languages. Remote Method Invocation is used to integrate the simulators in different computer environment. By applying the method to the partial simulators on the blast furnace, java-based in...
