Abstract: Planar flow casting is a rapid solidification forming technology, which has been widely concerned by academia and industry because of its ability to continuously produce metal strips or wires in near net shape. The technical parameters of planar flow casting process are very important to the formability and stability of strip / wire products. This paper summarized the influence of various process parameters on the formability of the strip, including the rotation speed of the copper roller, the pressure difference of the molten liquid, the gap between the nozzle and the copper roller, the width of the nozzle groove, the supercooling degree, the solidification speed, the cooling rate, the heat transfer coefficient and so on. At the same time, the future development of planar flow casting technology was prospected. The neural network algorithm in deep learning will be used to further quantify the influence of various technical parameters, and the application of planar flow casting technology to the industrial production of crystal strips is an important development direction.
