The usual practice in the manufacture of coke is to apply external heat to the oven containing the coke and maintaining the necessary temperature for a long time, so that the gases are driven from the coal, leaving the carbon in the form of coke. This process is usually a long one, requiring twentyfour hours or more for its accomplishment.

Modeling and optimization of coal blending and coking costs using coal ...

Coke is an important raw material in the steel industry, and its quality directly influences the smelting of iron and steel. To improve coal quality and reduce coal blending costs, we need to predict the coke quality and optimize the coal blending scheme. In this paper, we propose a modeling and optimization method based on the characteristics of the coal blending and coking process.
