Mathematical model of neutral angle for cold rolling of thin and ultralight gagestrips

Using a solution based on a physically substantiated model of friction stresses, the length of the forward slip zone has been studied and the position of the neutral section has been determined during cold rolling of thin and ultralight gage strips An updated mathematical model of the neutral angle for cold rolling of thin and ultralight gage strips has been proposed. It follows from (1) that the extreme conditions of cold rolling do not occur at α=2β, as is customary in the traditional theory of lengthwise rolling, but at α=nβ, i.e. much earlier since n<<2.
