Summary:A method for predicting a temperature rise history of a furnace core of a graphitizing furnace is described. In this method, a furnace resistance model of the graphitizing furnace is built. A heat transfer model of the graphitizing furnace is built. The heat transfer model includes a resistor material heat balance equation, a crucible heat balance equation, a graphite material heat balance equation, a thermal insulation material heat balance equation, and a refractory brick heat balance equation. An iteration calculation operation is performed by using a predetermined power transmission curve, the furnace resistance model, and the heat transfer model to obtain various furnace core temperatures of the graphitizing furnace corresponding to difference power transmission times until an aggregate power transmission time is equal to a predetermined value.
