Special Issue Information

Dear Colleagues,

Continuous casting and refining play a crucial role in steel production. Continuous casting enables the efficient solidification of molten steel into semi-finished products, enhancing productivity. Refining processes, such as LF and RH, precisely control chemical compositions and remove inclusions. Their combined application ensures the production of high-quality steel with enhanced mechanical properties and reduced defects, meeting the stringent demands of modern industries. Consequently, with the increasing demand for high-quality products, the improvement of equipment, and the advancement of automation and digitalization, metallurgical researchers have developed novel technologies, processes, and mechanisms for continuous casting and refining.

This Special issue aims to present new technologies, processes, and trends regarding the application of continuous casting and refining. Original research articles and reviews from academia and industry are welcome. The scope of this Special Issue includes, but is not limited to, the following topics: innovative casting techniques, the optimization of the refining process, clean steel technologies, improvements in the quality of cast products, digital and intelligent applications, and the impact of novel refractory materials. I look forward to receiving your contributions.

As the third generation of thin slab continuous casting and rolling technology, endless strip production (ESP) has been widely used in the steelmaking industry. The key equipment in this process, the funnel-type mold, is prone to accidents such as slag entrainment, surface cracks and steel leakage under high casting speed conditions. To reduce the incidence of the above accidents, the numerical model of flow, heat transfer and solidification in the funnel-type mold is established by using the k-ε model, enthalpy–porosity method and magnetohydrodynamics (MHD), and the influence mechanism of the mold cavity and submerged entry nozzle (SEN) on the molten steel is studied, providing a new solution for optimizing the ESP process. The results show that compared with the type-I mold, the influence of the geometric disturbance of the top cavity on the flow state of the middle and lower body is localized, while the type-II funnel mold increases the thickness of the solidified shell at the outlet of mold; the marked enhancement in solidified shell thickness and uniformity at the mold exit achieved through the type-II SEN due to the distribution of temperature and velocity are more reasonable, reducing the risk of surface cracks and steel leakage.
