Bar Mill Solutions

High-speed and special bar quality bar mills require equipment designed for high durability and maximum uptime to meet stringent productivity, tolerance, surface finish, and metallurgical qualities. As pioneers in long rolling equipment for over a century, this extensive industry-renown experience enables Primetals Technologies to configure new bar mills with the ultimate flexibility to produce traditional hot-rolled, quenched, tempered, and low temperature bar at the fastest rolling speeds.

Special Bar Quality (SBQ)

Rolling at lower temperatures (thermomechanical rolling) results in higher quality finished products with tighter tolerances and improved surface qualities. The Bar Reducing and Sizing Mill improves mill utilization while enhancing finished product tolerance thanks to the patented oval-round-round-round pass sequence, ensuring bar mills can roll special bar quality grades.

Bar Production Trends

The industry trend for increased production with added mechanical properties has caused modern bar mills to roll small size bar and rebar at high rolling rates, bridging the high-yield quench & tempered and fine grain processing routes together. Multi-slit and high-speed technologies ensure bar mills are capable of achieving high productivity, safety, and efficiency requirements, while state-of-the-art cooling technologies control the temperature distortion of the bar after rolling. The advanced Spooler system's entry nozzles have the longest life in the industry, saving bar mills maintenance-related costs. The Rotary Entry System's single-strand rolling after slitting increases product tolerance and quality, while the high-speed cooling bed rapidly and efficiently cools bars.

High-Speed, Industry-Renowned Equipment

State-of-the-art equipment for bar mills reduces operational and conversion costs, while maximizing production and operating efficiency through single-family rolling. The Morgan Vee No-Twist Mill, combined with high-speed cooling bed entry equipment, enables high productivity with vastly improved utilization compared to the traditional slit rolling process. Incorporated into the Morgan No-Twist Mill, eDrive technology enables the highest capacity roll housing in the industry, while increasing roll life and reducing wear.
