A method of rolling steel bars and steel wires with grooved rollers and a rolling guide without grooves

摘要

In a steel wire and rod rolling process using plane rolls, the roll bite of each roll pair is controlled so that width; thickness ratio of the rectangular section blank, after passage through the bite, is less than 1.5 Alternatively, or in addn, relatively small dia. rolls are used in which the roll dia. roll gap ratio D/H is no greater than(100/H)+5. Also claimed are roll guides for use in the process. The process provides stable rolling method using plane rolls, in which the wire or rod is deformed almost exclusively in the rolling direction without increase in width.
