Embodiment Construction

[0089] now refer to figure 1 , 2 and 2A, which illustrates a twin roll caster comprising a main machine frame 10 standing from the factory floor and supporting a pair of counter-rotatable casting rolls 12 mounted in modules in a roll cassette 11 . Casting rolls 12 are mounted in roll cassettes 11 for ease of handling and movement, as described below. The roll cassette 11 facilitates the rapid movement of the casting rolls 12 ready for casting from the set up position to the operative casting position as a unit in the casting machine and prepares the casting rolls 12 for removal from the casting position when the casting rolls 12 are to be replaced . There is no particular configuration of roll cassette 11 desired so long as it performs the function of facilitating movement and positioning of casting rolls 12, as described herein.

Abstract

A method and apparatus of continuously casting a thin strip by controlling roll crown are provided. The apparatus for continuously casting a thin strip by controlling roll crown includes at least twoexpansion rings positioned within and adjacent a cylindrical tube and spaced within 450 mm of edge portions of the cast strip formed on opposite end portions of casting rolls during a casting campaign. Alternatively or in addition, the apparatus includes at least one expansion ring within the cylindrical tube at a position corresponding to center portions of the cast strip formed on the casting rolls during a casting campaign. Each expansion ring has at least one heating element and an insulating coating thereon and is adapted to increase in radial dimension causing the cylindrical tube to expand changing roll crown of the casting surfaces of the casting rolls and thickness profile of the cast strip during casting.

Description

[0001] This application is an international application of US Application No. 14 / 946,872 filed November 20, 2015. technical field [0002] The invention relates to the casting of metal strip by continuous casting in a twin roll caster. Background technique [0003] In a twin roll caster, molten metal is introduced between a pair of counter-rotating horizontal casting rolls that are cooled so that the metal shells solidify on the surfaces of the moving casting rolls and are brought together at the nip preceding the horizontal rolls , to produce a solidified strip product that is delivered downward from the nip between the casting rolls. The term "nip" is used herein to refer to the general area where casting rolls are closest together. Molten metal may be passed from a ladle into a smaller vessel or series of smaller vessels from which it flows through metal delivery nozzles and nozzles located above the nip forming a casting pool of molten metal The casting pool is support...
