Title:
METHOD FOR CONTINUOUS CASTING OF STEEL
Document Type and Number:
WIPO Patent Application WO/2003/045608
Kind Code:
A1
Abstract:
A method for continuous casting of steel, characterized in that use is made of a combination of a mold powder having a fluorine content of less than 3 wt % and exhibiting a viscosity at 1300 °C of 4 to 10,000 poise and an immersion nozzle comprising a refractory material containing alumina as a primary component (specifically, an alumina refractory and&sol or alumina−carbon refractory). The method allows the stable production of a clean cast steel product with little melting loss and with no deposit of alumina, also in the case when an immersion nozzle comprising a refractory material containing alumina as a primary component is used.
