The paper considers stresses emerging in the skin of a continuously cast steel billet, as well as their values under the influence of temperature expansions in a novel patented design of a nickel mold with a two-circuit cooling system. According to the known values of heat flux densities at various distances from the top of the mold, the temperature of the slag-forming mixture and the average temperature of the steel billet skin are determined. Based on the established thickness of the billet skin, the temperature gradient therein is determined. At a steel casting speed of 4 m/min, the values of temperature stresses in the billet skin at various distances from the top of the mold were established not to exceed the values of the metal flow stresses at corresponding temperatures.

本文考虑了连铸钢坯表皮中出现的应力，以及在具有两回路冷却系统的镍模具的新颖专利设计中温度膨胀影响下的应力值。根据距结晶器顶部不同距离处的已知热流密度值，确定造渣混合物的温度和钢坯表皮的平均温度。基于所确定的坯料表皮的厚度，确定其中的温度梯度。在 4 m/min 的钢铸造速度下，距铸型顶部不同距离处的坯料表皮中的温度应力值被确定为不超过相应温度下的金属流动应力值。
