MULTIFUNCTIONAL STAND OF MILL FOR ROLLING H-BEAM AND METHOD FOR ROLLING H-BEAM IN SUCH STAND Russian patent published in 2002 - IPC

FIELD: processes and equipment for rolling H-beams. SUBSTANCE: multifunctional stand includes pair of right and left vertical rolls for reducing flanges by thickness; horizontal rolls for reducing necking portion by thickness and pair of upper and lower horizontal rolls arranged at both sides of rolls for reducing necking portion by thickness and including rolls for reducing flanges by thickness mounted with possibility of free motion in vertical direction by means of withdrawal mechanisms. In case of rolling for reducing flanges by width and reducing necking portion by thickness, rolls of horizontal roll pair designed for reducing flanges by width are shifted upwards and downwards that is why rolls designed for reducing flanges by width do not interfere with vertical rolls. EFFECT: enhanced accuracy of rolling wide-flange beams, lowered cost of rolling equipment, decreased length of rolling line. 4 cl, 35 dwg
