FIELD: process engineering. ^ SUBSTANCE: invention relates to metal forming, particularly to roll mill stand. Mill stand 1 comprises rolls 2, 3, guides 4, 5 arranged on stand inlet and outlet and fasteners 8 to secure guides 4, 5 to the stand. Said guides are arranged on stand structure, oriented along rolling direction W, before and after clearance 6 between rolls. Guides can be adjusted in direction perpendicular to axis 7 of rolls 2, 3 and direction perpendicular to rolling direction W, particularly in vertical direction V. Fasteners 8 have preset collapse point. Said fasteners comprise at least one expansion bolt. Fasteners 8 comprises at least two retainer plates 11, 12, 13 arranged perpendicular to axes 7 of rolls 2, 3 and rolling direction W to allow said one expansion bolt to pass there through to compress said plates. ^ EFFECT: minimised damages in failures. ^ 9 cl, 6 dwg |
