摘　　要：以低碳钢为例对双辊连铸过程进行了微观模拟。研究了浇注温度、拉坯速度、冷却强度等工艺参数对带材结晶凝固晶粒度的影响,得出了不同工艺条件对铸轧带材晶粒度的影响规律以及最佳的模拟参数。通过实验结果与数值模拟结果的对比,验证了模拟结果的正确性,说明模拟结果对实际有一定的指导意义。Taking low carbon steel as an example,the paper introduces the simulation about twin-roll casting process in micro presentation.The impact on the strip crystallization crystallite size by pouring temperature,casting speed,cooling intensity are studied in the paper,the influence rule with different process conditions on the casting material grain size and the best simulation parameters are obtained.Verifies that the simulation results are correct by comparing the experimental results with numerical simulations and shows that simulation results have some practical significance.
