<p>The invention concerns an improvement in the casting ring which is provided on the periphery of the wheel in continuous casting machines. This ring is characterized in that its entire internal surface is in contact with the cast metal in the region of solidification, it is mounted completely freely on its support means, and it has a thickness in the vicinity of 1 mm. These characteristics enable it to be deformed when hot into a shape which is similar to its cold profile. This gives rise to the possibility of controlling the solidification of ingots and the aptitude for withdrawing the ingots without surface defects at a temperature higher than that obtained by the customary machines.</p> |
