FIELD: plastic metal working, namely production of rolled stock, possibly manufacture of round or square cross section bars of hard-to-form metals or alloys, for example of titanium in bar rolling mills.
SUBSTANCE: method comprises steps of rolling billet simultaneously by means of two pairs of horizontal rolls mounted successively in roll grooved passes having vertical oval, then circle or square. Before strip is finally rolled to ready size it is not subjected to tilting around lengthwise axis in space between stands but strip with cross section in the form of flattened oval is guided into vertical oval. It provides elimination of twisting effect usually caused by tilting piece in space between stands.
EFFECT: enhanced quality of surface, improved stability of geometry size of product, reduced labor consumption and enhanced efficiency of process.
