Ziel
The final industrial goal of the present project is to develop a technology for high productivity casting of small round section bars with ultra fine solidification structure, which means equiaxed structure with very low segregation. The final target is to reach a productivity per strand of 30 t/h for a small diameter of 85 mm which means a casting speed of 12 m/min about twice faster than the present achievable speeds for long products. This project should pave the way to the near net shape casting for long products with a strand productivity level corresponding to that of the most modern continuous casters. To achieve this objective, two main technologies will have to be combined: a technology that leads to precisely control the initial solidification of the shell without being affected by hydrodynamic turbulence in particular, level variations of the meniscus; a technology that refines the internal structure of the product by inoculating the liquid metal with steel powder injected through a nozzle such as the Hollow Jet Nozzle.
