Embodiment Construction

[0085] now refer to figure 1 , 2 and 2A, which show a twin roll caster comprising a main frame 10 that rises above the factory floor and supports a pair of modules mounted in roll cassettes 11 that can Counter-rotating casting rolls 12. 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 as a unit in the casting machine from the setup position to the working casting position and facilitates the rapid removal of the casting rolls 12 from the casting position when the casting rolls 12 need to be replaced . The roll cassette 11 need not be of any particular construction, so long as it functions to facilitate movement and positioning of the casting rolls 12 as described herein.

[0086] The casting apparatus for continuously casting thin steel strip comprises a pair of counter-rotatable casting rolls 12 having casting surfaces 12A a...

Abstract

This disclosure concerns methods and apparatus for continuously casting thin strip where one or more expansion rings are positioned within at least one of a pair of casting rolls, and automatically measuring a thickness of the cast strip close to the first side edge of the strip using at least one sensor, and if the thickness measured is too thin, automatically decreasing the radial dimension of the expansion ring arranged in close proximity to the first side edge to cause the cylindrical tube to contract and increase the thickness of the cast strip during casting, and if the thickness measured indicates that the thickness of the cast strip is too thick, automatically increasing the radial dimension of the expansion ring arranged in close proximity to the first side edge to cause the cylindrical tube to expand and reduce the thickness of the cast strip during casting.

Description

[0001] Related Application Citations [0002] This application claims priority to and benefit of U.S. Provisional Patent Application 62 / 520,243 filed with the U.S. Patent Office on June 15, 2017, which is hereby incorporated by reference. Background technique [0003] The present invention relates to the casting of metal strip by continuous casting in a twin roll caster. [0004] In a twin-roll caster, molten metal is introduced between a pair of counter-rotating horizontal casting rolls, and the rolls are cooled so that the metal shell solidifies on the moving roll surfaces and The nips are brought together to produce a solidified cast strip product that is conveyed down 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 poured from a ladle into one or a series of smaller vessels from which the molten metal flows through metal delivery nozzles and nozzles located above t...
