    摘要： In a bearing assembly for a roll neck (12) in a rolling mill, an inner seal ring (26) is mounted with an interference fit as by shrink fitting, on an end portion of an inner bearing component (18'), e.g., the sleeve of an oil film bearing or the inner race of a roller bearing. The end portion (42) of the inner bearing component is suitably dimensioned and configured to deflect radially inwardly under the influence of hoop stresses developed as a result of the aforesaid interference fit, thereby causing the inner seal ring (26) to be inclined towards the roll end face (16). The end portion (42) of the inner bearing component has an outer diameter which is larger than the outer diameter of the remainder of the inner bearing component.

    摘要： A roiling mill roll stand has a housing removably mounted on a bridge support A pair of work rolls and their respective bearings and bearing chocks are contained within the housing. Separating devices act on the bearing chocks to maintain a gap between the work rolls. Hydraulic roll positioning cylinders are carried in the bridge support and are arranged to act on the bearing chocks of one of the work rolls. The housing together with the work rolls, bearing chocks and separating devices is removable as a unit from the bridge support, while allowing the hydraulic positioning cylinders to remain undisturbed.

    摘要： A method for rolling and heat treating small diameter stainless steel rod, comprising the following sequence of steps; cooling the rod prior to and during finish rolling to increase its stiffness; passing the rod through a sizing mill to achieve close tolerances; subjecting the rod to additional water cooling to chill its surface and thereby improve its resistance to surface scratching; forming the rod into rings which are received in an offset pattern on an open moving conveyor; subjecting the offset rings moving along the conveyor to a solid solutioning treatment by reheating and water quenching the same; and then air cooling and drying the rings before collecting them into coils.

    摘要： A method and apparatus for quenching steel rod in a high speed rolling mill is provided wherein a liquid coolant is preliminarily applied to the rod prior to its exiting from the mill finishing train in order to increase the column strength of the exiting rod by lowering the surface temperature thereof to less than about 950°C. Thereafter, as the rod progresses through additional liquid cooling devices on the way to the mill laying head, tractive forces are applied to the rod. The aforesaid increase in rod column strength acts in concert with the application of tractive force to ensure that the rod has sufficient rigidity and forward momentum to pass from the finishing train through the liquid cooling devices and to and through the laying head.
