摘要
A method is provided for extending the life of a refractory lining of a blast furnace hearth. The refractory hearth has temperature probes embedded in the floor and walls thereof. The method includes periodically measuring temperatures indicated by the probes and determining the campaign maximum and current average temperature readings to locate two solidification isotherm representing the wear line of the refractory and the inner surface of the protective metal layer. The thickness of the protective layer is determined from the distance between the solidification isotherms representing the refractory wear line and the inner surface of the metal skull. From this determination sufficient thickness of the protective layer is maintained during actual operation of the furnace.
