FIELD: process engineering.
SUBSTANCE: invention relates to application of reversing mill stand as a roughing or a finishing stand. Mill stand 20 has top and bottom support rolls 2, 4 engaged with appropriate top and bottom working roll 1, 3. Said rolls are replaced quickly and easily due to arrangement of top guide 8 at mill stand inlet and outlet to engage with working roll 1 and to be coupled via first actuator 6 with mill stand top zone. Top scraper 11 is engaged with top working roll 1 and displaced by second actuator 12 relative to said top working roll 1. Top guide 8 is retained in top and bottom vertical guides 9, 10 to be displaced therefrom by first actuator 6 from bottom vertical guide 9 and turned by third actuator 7 outward toward appropriate top working roll 1. Bottom scraper 13 is arranged at mill stand inlet and outlet to be rearranged by turn relative bottom working roll 3 effected by fourth actuator 14.
EFFECT: faster replacement of rolls.
