Java-based integrated non-stationary blast furnace simulator.

The simulator was developed from a stationary model consisting of a burden distribution model and a furnace process model, the latter including sub-models for burden distribution, gas flow, solid flow, chemical reactions and heat transfer. Remote method invocation (RMI) was used to integrate the partial simulators which are executed in different computer environments and Java native interface (JNI) was employed to integrate simulators developed in different programming languages. The non-stationary model was able to satisfactorily calculate the dynamic temperature in a blast furnace.
