ROD PRODUCTION METHOD Russian patent published in 2001 - IPC

FIELD: manufacture of rods of steels and alloys. SUBSTANCE: method comprises steps of rough shaping of initial blank in reversing stand pass system: shallow oval - vertical oval with tilting by 90 degres after each pass. Dimensions of blank cross section at rolling blank in roll grooved passes except first one are formed according to relation bn+hn =hn-1 + bn+1, at first pass - according to relation b1+h1=b2+bo, where b,h - width and height of deformed blank, n - number of pass along rolling process, bo -width of initial blank. EFFECT: enhanced quality of rolled rods due to high accuracy of adjustment of near-roll fitting and spacing first pass by some distance from bearing assembly in order to prevent water falling on surfaces of roll grooved pass. 1 dwg, 2 tbl
