Abstract

A process and apparatus uses a wire rolling installation 1, with the rolled wire being subjected to a heat treatment. In order to produce a high-grade steel wire, for use in reinforcing concrete, in coil form with an annealed marginal martensite layer and a core comprising ferrite and perlite, the rolled wire is passed through a water cooling section 2 prior to a first wire drive means 3,with temperature equilibrium between the core and marginal layers being produced in a guide means 4 between the first wire drive means 3 and a second wire drive means 5. Provided downstream of the wire drive means 5 is a turn laying means 6 which is mounted in an inclined position of about 10 DEG and with which the steel wire which has been subjected to heat treatment up to that time and in respect of which the formation of its structure has been concluded is laid down in regular turns. The coiled steel wire passes over a roller bed 7, a conveyor 8 where it is cooled by air cooling means 19, over a roller bed 9, and is finally collected on a mandrel 10. <IMAGE>
