Window and roll chock arrangement for a rolling mill

In a rolling mill stand comprising upright housing means,

• a vertical window in said housing means,
• a pair of upper and lower work rolls received in said window having their axes of rotation in a substantial common vertical plane and arranged to form a roll pass, each said roll having bearing chock means for rotatably supporting the opposite ends of said rolls in said window, in which similar ends of said rolls form cooperative pairs, each pair comprising an upper and lower chock means, said chock means having opposite vertical sides,
• said chock means for said lower roll having a side remote from said pass line,
• said housing means having stationary block members for said opposite vertical sides of each chock means extending into said window at a location to lend support to said opposite sides of said chock means,
• intermediate means for each chock means arranged between and in contact with each said block member and an associated said vertical side of said chock means, in a manner to permit said chock means to move axially of the axis of an associated roll relative to said intermediate means and to permit said intermediate means to move vertically with respect to said window relative to an associated block member,
• means arranged in said window contact with and extendable between each said cooperative pair of chock means for vertically separating said rolls with respect to said window and supporting said rolls in a separated condition,
• each of said opposite side of said lower chock means having carrying means,
• each said block member comprising a pair of rail means arranged adjacent said opposite sides of said lower chock means, for selectively engaging said carrying means thereby allowing in said separated condition said rolls as a unit with their chock means to be removed and replaced to and from said window,
• means carried by each said block member connected to said rail means for moving said rail means into and out of operative and inoperative positions, and
• said pair of rail means arranged in a generally coplaner relationship with said side of said chock means of said lower roll remote from said roll pass when in said operative and inoperative positions.
