چکیده
A practical method of JIT modelling for a blast furnace process data whose characteristics are very complicated physical phenomena and stiff nonlinear process are studied. The proposed method is composed of severely selecting process data variables by stepwise method and searching the past similar data in quantized topological space constructed by the selected variables. The effectiveness of this method is confirmed. It is also confirmed that it is sufficiently possible to apply this method to online use because the calculation time is quite short for searching the past similar data and estimating the future.

Development of an Online Blast Furnace Burden Profile Measuring System
Gas permeability in a blast furnace is directly influenced by the burden profile, which is the result of the charging angle collocation. An obviously increment in both iron-making productivity and furnace campaign life will be observed in a high heat utilization furnace with uniform gas permeability. An online burden profile measuring device without gas leakage risks and heavy maintaining load ...
