| titleOfInvention |
Immersion nozzle for continuous casting of steel and continuous casting method of steel using it |
| abstract |
Nozzle for clean steel continuous casting that can eliminate the adhesion of Al 2 O 3 inclusions to the wall surface of the nozzle inner cavity in continuous casting of molten steel, and can fully exhibit the effect of the rotor blades as a countermeasure against the flow of molten steel flowing down the nozzle. to be. Preventing the attachment of Al 2 O 3 inclusions to the inner wall and the inner wing by installing turning blades in the inner hole formed by the refractory with Ca0 / Mg0 weight ratio and apparent porosity controlled and having an inner layer formed as annular refractory with a thickness of 3 to 20 mm. And long-distance drift of molten steel can be effectively carried out. In addition, by injecting an inert gas from the upper nozzle to the upper position of the swivel vane, the flotation of Al 2 O 3 -based inclusions is promoted to suppress mixing into molten steel. A stable and good high cleanness steel quality can be obtained. |
