Abstract: A continuous casting process of a steel semi-product is provided. The process includes a step of casting using a hollow jet nozzle located between a tundish and a continuous casting mould. The nozzle includes, in its upper part, a dome for deflecting the liquid metal arriving at the inlet of the nozzle towards the internal wall of the nozzle, defining an internal volume with no liquid metal. A simultaneous step of injecting powder through a hole of the dome occurs. The powder has a particle size of 200 μm or less. The dome includes a first device to inject the powder without any contact with the dome and a second device to avoid sticking or sintering of the powder onto the first device.

Abstract: Continuous casting equipment for a flow of liquid metal from a tundish into a mold is provided. The equipment includes a vertical duct disposed upstream of the mold with respect to the direction of travel of the liquid metal. The duct includes from upstream to downstream a refractory ring, a copper tube with an internal diameter D and a submerged entry nozzle. A dome is disposed inside the refractory ring and includes a sloped upper part, the upper part is defined so as to deflect the liquid metal coming from the tundish towards the inner walls of the vertical duct. The diameter D of the copper tube ranges between a minimum diameter equal to Q/3.75 and a maximum diameter equal to Q/1.25, where Q is the nominal liquid metal flow rate of the equipment and is between 200 and 800 kg/min and D is the diameter expressed in mm.
