CONTROL METHOD OF HIGH-SPEED MODE OF BROADBAND ROLLING MILL DEFLECTING ROLL TABLE Russian patent published in 2021 - IPC B21B37/46 

FIELD: technological processes.

SUBSTANCE: invention relates to rolling and can be used for rolling and transporting thin and extra-thin strips of hot-strip broad-strip rolling mills at discharge roller bed. Method of controlling the speed mode of the roller broad gullies roll table includes creation of the roller rollers peripheral speed exceeding speed of the front end of the strip and reduction of circumferential speed of the rollers at the approach of the front end to the coiler. Before the pull rollers of the reeler, the speed of a group of rollers is reduced in the section with length of 15-25% of the roll table length, spaced from the front end of the strip at distance of 10-20 m at the moment, when the distance from the front end of the strip to equipment potentially capable of contacting with the end of the strip and / or disturbing stability of movement of the front end is 5-15 m, 2-7% lower than the speed of the strip. After the strip is fixed to the coiler drum, the speed of the rollers is equalized with the speed of the strip.

EFFECT: result is reduction of jams and increase of strip rolling speed.
