Fluid-leveled bearing plate

1. A linear bearing assembly and a mill stand comprising:

a mill stand for rolling steel products and having a mill window;

a linear bearing plate having a plurality of apertures, said linear bearing plate being held within the mill window;

a base plate adapted to support the linear bearing plate, said base plate being held against a mill stand surface within the mill window;

a metal thrust bushing inserted into one of the plurality of apertures in the linear bearing plate and directly engaging both the linear bearing plate and the base plate;

a threaded fastener passing through said thrust bushing and securing the thrust bushing and base plate and linear bearing plate to the mill stand;

a sealing structure defined between the bearing plate and the base plate, said sealing structure including at least a channel in the linear bearing plate and a channel in the base plate with a seal inserted into both channels and adapted to seal a volume defined between the linear bearing plate and the base plate; and

a hardening resin adapted to be injected into the volume via at least one injection port wherein an orientation between the linear bearing plate and the base plate is adjustable, and with no portion of the hardening resin being positioned between a head of the threaded fastener and the base plate.

2. The linear bearing assembly and mill stand of claim 1 wherein the base plate and the bearing plate are vertically oriented within the mill stand and the metal thrust bushing is generally cylindrical with side surfaces directly engaging an inner surface of said one of the plurality of apertures in the linear bearing plate and a flat end directly engaging the base plate.

3. The linear bearing assembly and mill stand of claim 1 further comprising: at least one pressure sensor adapted to provide a signal representative of a pressure within said volume before, during or after a resin injection.

4. A linear bearing assembly and mill stand comprising:

a mill stand for rolling steel products, said mill stand having a mill window;

a base plate positioned within the mill window and adapted to support a linear bearing plate within the mill stand;

a metal thrust bushing and threaded fastener for holding the linear bearing plate against the base plate, with said thrust bushing directly engaging both the linear bearing plate and the base plate, and said threaded fastener securing the linear bearing plate and base plate to the mill stand;

a sealing structure defined between the linear bearing plate and the base plate, said sealing structure including a channel in the base plate and a channel in the linear bearing plate with a seal inserted into both channels and adapted to at least partially seal a volume defined between the base plate and the bearing plate; and

a hardening resin material injected into the volume via at least one injection port with an orientation between the base plate and the linear bearing plate being fixed by said resin material.

5. The linear bearing assembly and mill stand of claim 4 further comprising: a plurality of metal-working rolls supported on chocks, with said chocks transferring loads to said linear bearing plate and said base plate.

6. The linear bearing assembly and mill stand of claim 5 further comprising a plurality of bearing plates, with each of said plurality of bearing plates being separately and independently adjustable via said fluid injection.

7. The linear bearing assembly and mill stand of claim 4 further comprising: at least one pressure sensor adapted to provide a signal representative of a pressure within said volume before, during or after said resin injection, and wherein no portion of the hardening resin is positioned between a head of the threaded fastener and the base plate.

8. The linear bearing assembly and mill stand of claim 7 further comprising a data processor for collecting pressure data and for providing a report designed to optimize a fluid injection procedure.

9. A method of adjusting a linear bearing assembly secured to a metal rolling stand, said method comprising:

providing a linear bearing plate and a base plate adapted to support the linear bearing plate within a metal rolling stand, with a channel in the bearing plate and a channel in the base plate;

securing the linear bearing plate to the base plate with a metal thrust bushing and threaded fastener, said thrust bushing passing through an aperture in the linear bearing plate and directly engaging the base plate at one end of the thrust bushing and directly engaging an inner surface of said aperture in the linear bearing plate;

placing a sealing structure between the bearing plate and the base plate, said sealing structure being inserted into both channels and being adapted to seal a volume defined between the linear bearing plate and the base plate; and

injecting a hardening resin material into the volume via at least one injection port, with said resin material being injected at a sufficient pressure so as to alter an orientation of the linear bearing plate or the base plate toward an initial geometric orientation, with an output of the metal rolling stand being altered based on said resin material injecting.

10. The method of claim 9 wherein the hardening resin maintains the orientation of the linear bearing plate and the base plate upon hardening, and wherein no portion of the hardening resin is positioned between a head of the fastener and the base plate.

11. The method of claim 9 further comprising:

determining a pressure within the volume with a pressure sensor and adjusting the pressure of the resin material injection based on said determining.
