Abstract

The invention belongs to the technical field of double-roller cast rolling. On the basis of practice of a tracing method prompted by a patent application file CN2021101226378, an applicant discovers unique characteristics of'solidified shell 'growth in a molten pool. According to the unique characteristics of'solidified shell 'growth, the applicant provides a crystallization roller yielding movement method for enhancing the stability of the double-roller casting and rolling process in the patent application document 2022101047141. The invention provides a double-roller casting and rolling device for implementing yielding movement of a crystallization roller. The double-roller casting and rolling device is used for implementing a yielding movement method of the crystallization roller, which is described in the patent application file 2022101047141 and is used for enhancing the stability of a double-roller casting and rolling process.

Description

technical field [0001] The invention belongs to the technical field of twin-roll casting and rolling, and in particular relates to a twin-roll casting and rolling device for carrying out concessional movement of crystallization rolls. Based on the practice of the tracking method suggested by the patent application document CN2021101226378, the applicant discovered a key feature of the growth of the "solidified billet shell" in the molten pool, which is completely different from the conventional continuous casting process: two straight lines converge into a Kiss point. According to the growth characteristics of the "solidified slab shell", the applicant proposed a method of concessional motion of the crystallization rolls for enhancing the stability of the twin-roll casting process in the patent application document 2022101047141. Using the concessional movement method of the crystallization roller, an additional periodical or non-periodic movement space is provided for the "so...
