| 摘 要： | 连铸坯凝固末端位置的确定方法有实验测定法和数学模型法。针对鞍钢厚板坯连铸机，采用有效比热容法建立板坯连铸二冷凝固传热数学模型来预报凝固末端的位置，用实验测定值验证了模型的可靠性。应用数学模型分析拉速对厚板坯凝固末端位置的影响，将计算结果回归得到了X65管线钢和船板钢在不同拉速范围内凝固末段位置和拉速的数学关系式，可为现场控制连铸凝固终点提供参考。 |

| Abstract: | Final solidifying end of continuous casting slab can be obtained by testing or simulating.Aiming at the thick slab caster,mathematical models of solidification and heat transfer for thick slab based on effective specific heat method have been established,which can be used to predict final solidifying end.The model which has been established is reliable through comparing with measurement results.The effect of casting speed on the final solidifying end has been analyzed.Simulation results have been regressed ... |
| Keywords: | continuous casting mathematical model final solidifying end |
