From the WinLink direct rolling to the ERT-EBROS billet welding, the processes and technologies for endless rolling of long products can play an important role in minimizing the consumption of energy, improving product consistency, and maximizing yield.
Primetals Technologies has installed or upgraded more than 1,000 rolling mills on six continents. These mills have set worldwide benchmarks for technological leadership, reliability and performance.
ERT-EBROS - Billet Welder
Billet welding can provide several advantages, as improvement of the metallic yield, increase of mill utilization factor and flexibility of selection of the coil or bundle weight. But the full exploitation of these benefits can only be obtained with an equipment design which offers a clean operation and small maintenance requirements, to so minimize the stops. The ERT–EBROS by Primetals Technologies is the most advanced billet welding technology in the market, conceived for consistent quality operation with low-maintenance requirements. Its innovative design and optimized automation offer a clean operation, and allow welding to run with no interruption over multiple production shifts.
