Abstract (en)
[origin: EP2263815A1] The mold (6) for the continuous casting of double T-shaped preliminary sections, comprises a mold passage (8), where all the interior walls (7a, 7b, 7c, 7d, 7e, 7f, 7g, 7h, 7i, 7j, 7k, 7l) of the mold in the mold passage have a tapered course running linearly from top to bottom. The tapered course is dimensioned depending on the degree of shrinkage of the cast strand. The interior walls are linear, curve-shaped, curved and/or parabolic and are adapted for the stiffness of cast strand. The interior walls are produced through chip removing machining. The mold (6) for the continuous casting of double T-shaped preliminary sections, comprises a mold passage (8), where all the interior walls (7a, 7b, 7c, 7d, 7e, 7f, 7g, 7h, 7i, 7j, 7k, 7l) of the mold in the mold passage have a tapered course running linearly from top to bottom. The tapered course is dimensioned depending on the degree of shrinkage of the cast strand. The interior walls are linear, curve-shaped, curved and/or parabolic and are adapted for the stiffness of cast strand. The interior walls are produced through chip removing machining. The middle of the mold passage is formed through its middle axis and/or through the plain transverse to longitudinal formation of the mold.
