【Abstract】 he main idea of this paper is:Using an elliptic cylindrical ingot to express an ingot which has a rectangular cross section, then using conduction shape factor to estimate the thermal state of the ingot. This method is useful for estimating the thermal state of rectangular parallelepiped ingots.更多还原
