CONTINUOUS CASTING EQUIPMENT |
摘要 |
Continuous casting equipment for a flow of liquid metal from a tundish into a mould is provided. The equipment includes a vertical duct disposed upstream of the mould 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. |
