In the cupola operation, the height of cokebed is one of the decisive factors in maintaining proper melting conditions. Using a small size experimental cupola, a series of test operation was performed and the operating variables including tapping temperature were measured. After the given period of operating time, melting was forced to cease and the contents of the cupola stack were examined. A simplified differential equation has been applied to construct a model by which the variation of cokebed height can be simulated, and the estimated results were compared with the actual bed height, yielding fairly good accordance between them.
