Abstract

The procedure uses wire in coils or bundles. In a first stage, the continuous welding together of ends of wires in successive wire bundles, forms a long continuous wire. An arrangement, containing a clamping roller, a conical guide, a guide table, or a rotary drum prevents uncoiling in a second stage. In a third stage, the bundles are deposited with loose windings, which do not get entangled on a conveyor table. In a fourth stage, the windings are moved into a heater, where they are warmed. The warmed steel is hot-rolled to the initial profile in a fifth stage and in a sixth stage, the rolled product is cut into lengths having the required cross section.
