As an emerging process, the ultra-thin strip casting has significant advantages in the production of non-oriented electrical steel with a short process flow. However there are problems of castability and poor quality of casting product, which are significantly influenced by the interfacial heat transfer. During the production of ultra-thin strip casting, natural deposition films are deposited while the steel solidifies on the water-cooled copper rolls. The deposited films between the molten steel and the rolls significantly affect the interfacial heat transfer. In this study, the copper substrates used for the experiments were modified to make them more accurate. The effect of naturally deposited films on the interfacial heat transfer during sub-rapid solidification of non-oriented electrical steel was investigated by means of droplet solidification. The temperature data collected by two pairs of high-sensitivity thermocouples are calculated by the Inverse Heat Conduction Program (IHCP) to obtain the heat flux.
