The dimensions of a product passing through the finishing block of a roll rolling mill are measured. Where the dimensions of the product exiting the last finishing stand are out-of-tolerance, a calculation is made to determine the extent to which the roll parting of the work rolls of one of the two last finishing stands must be adjusted to bring the product into tolerance. Based on the calculated adjustment, progressively smaller adjustments are made to the roll partings of the work rolls of the upstream finishing stands to distribute the work which must be performed on the product to bring the product into tolerance.

Automatic gauge control system for multi-stand tied block rod rolling

A horizontal or vertical roll stand for a rod or bar rolling mill comprising a pair of work rolls having a plurality of grooves spaced axially along the surfaces thereof, each work roll being journalled between bearings contained in bearing chocks, with the bearings being adapted to accommodate axial adjustment of the work rolls in relation to the bearing chocks. The bearing chocks are supported in a housing with the work rolls in parallel relationship and with the grooves defining a plurality of roll passes. An axial roll adjustment means is associated with each work roll. Both of the axial adjustment means are driven by a common axial adjustment drive. A clutch is connected between one axial adjustment means and the axial adjustment drive. When engaged, the clutch permits the axial adjustment drive to operate through both axial adjustment means, thus axially adjusting both work rolls simultaneously. When the clutch is disengaged, the axial adjustment drive operates through only one axial adjustment means, with the result that one work roll is adjusted axially in relation to the other work roll. The work rolls are additionally acted upon by roll parting adjustment means driven by a common parting adjustment drive. On vertical roll stands, the axial adjustment drive and the parting adjustment drive are supported on a platform overlying the roll housing. Both drives are connected to their respective adjustment means via couplings which are separated and assembled in response to vertical movement of the platform between a lowered operative position supported on the roll housing and an inoperative position spaced vertically thereabove.

Roll stand for a rod or bar rolling mill

An apparatus for observing the relative alignment of two pairs of guide rollers on a rolling mill roller guide. The roller guide is positioned with its guide roller pairs spaced along an axis extending between two light sources. A dichroic mirror is arranged between each pair of guide rollers and its adjacent light source. One dichroic mirror reflects blue light while transmitting red light, and the other dichroic mirror reflects red light while transmitting blue light. The light reflected from both dichroic mirrors is recombined by a third dichroic mirror and is then projected onto a screen as red and blue images which may be compared visually with a reference outline on the screen, the said outline being representative of proper guide roller alignment. When the roller pairs are properly aligned, the red and blue images coincide on the screen to produce a white image aligned with the reference outline.
