Abstract:
Continuous casting is one of the ingot production methods in which the product has uniform chemical structure, low defects and high production rates. These days, carbon steel and nonferrous alloys are mainly produced by this special method. The design of continuous casting process includes a lot of difficulties due to its technological complexity. One of the most important aspects of this process is the heat transfer during solidification. In the present study, a new mathematical model and its corresponding numerical solution method have been introduced to establish the condition of directional solidification along the major ingot’s axis. The controlling parameters used in the model are pooling rate, the environment temperature, i.e., temperature of the internal mold walls and flow rate of the secondary cooling system, and the interfacial heat transfer coefficients corresponding the mold walls and secondary cooling system. The feasibility of the presented method has been demonstrated through several numerical experiments
