A method for determining the rational distribution of cooling intensity of a round billet in a SCZ within which the amount of heat removed from the surface of the calculated section of the billet at each instant of time is equal to the sum of the amount of heat released at the solidification front and the amount of heat corresponding to already solidified metal mass cooling at a specified rate, is proposed. The adequacy of the method is verified by prescribing the distribution of the cooling intensity obtained as boundary conditions in a mathematical model of the temperature field of a continuously cast billet. During treatment of the simulated results values of the solidification coefficient are established that within the limits of the permissible error are consistent with the values used as starting data within the framework of the method proposed.

一种确定SCZ中圆坯冷却强度的合理分布的方法，其中在每个时刻从计算的坯段表面去除的热量等于释放的热量之和提出了在凝固前沿的温度，并提出了与已经凝固的金属块以指定速率冷却相对应的热量。通过在连续铸造坯料的温度场的数学模型中规定作为边界条件而获得的冷却强度的分布，验证了该方法的适当性。
