【Abstract】 The heat transfer coefficient is the key parameter to calculate the temperature field of continuous casting ingot. In this paper, the characters of heat transfer between the high temperature solid surface and the cooling water and the determination of heat transfer coefficient are discussed. Besides, the essence of influencing each other of the heat transfer coefficient and the temperature field is pointed out.更多还原
