【Abstract】 In this paper the calculation process of heat transfer in metal mold system under o-petating condition of centrifugal casting of iron pipe was simplified and the thermal analysis model of metal mold was developed w.ith considering the temperature dependence specific heat and thermal conductivity of mold material. The solution of equation is carried out numerically .The temperature variation in centrifugal mold has been measured in experimental condition to verify the adequacy of this model.It was found thatthe results of solution were in good agreement with experimental data.更多还原
