Abstract
In a twin roll continuous caster, the contour of the strip cast is controlled during casting by regulating the temperature of temperature-regulating medium circulated through temperature-regulating passages in the casting rolls spaced inward of cooling passages in the circumferential portion adjacent the casting surfaces. The temperature-regulating passages may be positioned in the circumferential portion or in the inner portion of the casting rolls, or both.
Claims15
A twin roll continuous caster comprising:
- a pair of casting rolls having a first end portion and a second end portion laterally positioned to form a nip adapted to support a molten casting pool formed therebetween and to cast a thin strip cast downwardly from between the casting rolls;
- the casting rolls comprising circumferential portions having a plurality of circumferential cooling passages, each having a first end portion and a second end portion, adjacent a circumferential casting surface, and a temperature-regulating passage or passages spaced inward of the cooling passages with each having a first end portion adjacent the casting roll first end portion and a second end portion adjacent the casting roll second end portion and extending between said first end portion and said second end portion of the temperature-regulating passage or passages through the casting rolls;
- a cooler adapted to cool cooling liquid supplied to the cooling passages through inlets at the first end portions;
- a temperature-regulating medium supply unit;
- and
- a temperature-regulated temperature-regulating medium adapted to enter inlets at the first end portions of said temperature-regulating passages from the temperature-regulating medium supply unit and adapted to discharge the temperature-regulating medium through outlets at the second end portions of the temperature-regulating passages.

A twin roll continuous caster comprising:
- a pair of laterally positioned casting rolls each having a first end and a second end forming a nip therebetween, adapted to support a casting pool of molten metal above the nip, the casting rolls adapted to counter-rotate to form thin strip cast downwardly from the nip;
- the casting rolls having an inner portion and an outer circumferential portion;
- the outer circumferential portion having at least one set of passages circumferentially positioned in the casting roll adjacent the casting surfaces adapted to transport liquid cooling liquid ;
- and,
- the inner portion of the casting rolls comprising a passage or passages adapted to carry a temperature-regulating medium extending between adjacent the first end of the casting rolls and adjacent the second end of the casting rolls wherein the passage or passages is/are located within the casting rolls.
