TO 33 Wire

Jernkontoret's technical area 33, Wire, is where collaboration takes place between companies, research institutes and higher education institutions interested in wire production. 

Production of hot rolled wire rod involves feeding out the wire in coils that are left to cool. 

The process of wire drawing into finished wire products normally begins with descaling of the oxide layer on wire rods delivered from the wire rod mill. The process continues with cold drawing of wires to the final, predetermined dimension. This takes place via repeated area reductions and continuously by way of passes with wire drawing dies, which are arranged in a drawing block or capstan. In the drawing of thinner wire, the wire rods are annealed and pickled before renewed cold drawing takes place.


Wire products include wire racing bearings, spring wire, welding wire, staple wire, high resistance electrical wire, wire for drills, surgical suture wire, etc.

Committee meetings are arranged 2-3 times per year, often on the premises of member companies.
