数值模拟轧辊复合层连续铸造，采用分段直线拟合曲线和控制容积法。提出连续铸造轧辊复合层界面良好熔合的判据。采用直接优选法，反推重要工艺。获得轧辊复合层连续铸造法生产装置的总体设计方案。模拟得到生产良好复合轧辊、漏钢等不同的生产工艺条件。 Numerical simulation roll composite layer continuous casting, using piecewise straight line fitting curve and control volume method. The criterion of good fusion of continuous casting roll composite interface was proposed. Using direct optimization method, reverse the important process. The overall design scheme of the production equipment for continuous casting of roller composite layer was obtained. Simulated to produce a good production of composite roll, steel and other different production conditions.
