Abstract：Simulation in thermal process for blast stove group is advanced in this paper for effectively providing hot blast with required temperature and volume to blast furnace. The model to simulate the thermal process of a single blast stove is established with two dimension non-steady heat transfer theory based on different operation rules in gas period and blast period. Then algorithm of gas and blast periods for operation rules is proposed by blast stove group model considering mixing blast calculation for single blast stove in blast period. It can ensure that blast stove keeps optimum combustion in gas period and high temperature blast in blast period. A simulation model is developed to be verified in a steelmaking plant. The result shows it’s accurate to perform the process of blast stove group and also provide guidance for opearators.
