Tundish and method for production of a metal strip of high purity |
摘要 |
To achieve the highest possible separation rate for foreign particles in a tundish combined, at the same time, with a minimized level of inclusions, the refractory-lined interior space of the tundish, as a function of an operating bath level (h), satisfies the condition that a dimensionless ratio (kappa) of the refractory-lined surface area (A<SUB>ref</SUB>) to the filling volume (V) which is delimited by this refractory-lined surface area and the bath-level-dependent exposed surface area (A<SUB>Top</SUB>) and results from the relationship <maths id="MATH-US-00001" num="00001"> <MATH OVERFLOW="SCROLL"> <MROW> <MI>kappa</MI> <MO>=</MO> <MFRAC> <MSUB> <MI>A</MI> <MI>ref</MI> </MSUB> <MSUP> <MROW> <MO>(</MO> <MI>V</MI> <MO>)</MO> </MROW> <MFRAC> <MN>2</MN> <MN>3</MN> </MFRAC> </MSUP> </MFRAC> </MROW> </MATH> </MATHS> be between 3.83 and 4.39.
