ROLL HOUSING FOR STRIPS OR PLATES MANUFACTURING Russian patent published in 2012 - IPC B21B13/14 

FIELD: rolling-mill machinery.

SUBSTANCE: invention relates to the roll housing equipped with the working rollers for manufacturing the strips or plates which lean on back-up rolls or intermediate rolls and on back-up rolls; in the roll housing at least one of the above rollers has the delineated by the nonlinear mathematic function barrel outline passing along all the efficient length of the barrel, and the barrel outline of this at least one roller located in at least one of the border zone of the linear extent of the roller has edges and in these border zones forms the adjusted barrel outline which is created by the deduction of the nonlinear mathematical function delineating the outline of the edge from the nonlinear function delineating the barrel outline, at that the angle of ascent t of the outline of the barrel and the angle of ascent t of the adjusted outline of the barrel in the transition spot P from the barrel outline to the adjusted barrel outline are equal.

EFFECT: minimization of the nonuniformity of the load distribution along the contact line of two adjacent rollers and in particular in the strip border zone.
