| Abstract: | The average interfacial heat exchange coefficient between twin roll thin strip and roll is an important calculation parameter to numerical simulation research of twin roll thin strip continuous casting process, so measuring the coefficient has very important theoretical meaning and practical value. In this paper the average interfacial heat exchange coefficient was measured by the method which experiments and numerical calculation were associated. The result of the practical measurement process shows that the measurement of the average interfacial heat exchange coefficient can be finished simply by experimental equipments and calculation method which were adopted in this paper, and these methods can be applied to different size's twin roll casters. |
