Abstract
A vacuum roll mill stand comprises a housing closed at opposite sides with covers and having its interior brought in communication with a vacuum pumping means to thereby form a chamber adapted to accommodate chocks carrying workrolls geared through the intermediary of spindles to a drive. The chocks together with the workrolls are secured on one of the housing covers thereby forming a frame, the housing being annular in shape and arranged so as to have its geometrical axis coincident with the axis of rolling; the housing also being fitted with through openings adapted to receive the spindles together with vacuum seals.
