Abstract
The method of producing thin cast strip by continuous casting having a side dam assembly. The side dam assembly includes a side dam having opposite outer surfaces, one surface contacting molten metal and the opposite outer surface having fastening portions capable of attaching the side dam to a side dam holder, to hold the side dam in place during casting without exposed portions of the side dam holder extending substantially beyond the opposite outer surface toward the outer surface for contacting molten metal.
Claims7
A method of producing thin cast strip by continuous casting comprising the steps of:
- a) assembling a pair of casting rolls having a nip therebetween;
- b) assembling a metal delivery system comprising side dams adjacent the ends of the nip to confine a casting pool of molten metal supported on casting surfaces of the casting rolls, where each side dam has opposite outer surfaces, one surface contacting the molten metal and the opposite surface having fastening portions capable of attaching the side dam to a side dam holder to hold said side dams in place during casting, without a substantial exposed portion of said side dam holder extending beyond said opposite outer surface of said side dam;
- c) introducing molten steel between the pair of casting rolls to form a casting pool supported on casting surfaces of the casting rolls confined by said side dams;
- and
- d) counter-rotating the casting rolls to form solidified metal shells on the surfaces of the casting rolls and cast thin steel strip through the nip between the casting rolls from said solidified shells
