Today's demands for flexible and economic production of hot rolled strip and plate can only be met by customized solutions that are based on an in-depth knowledge of technological process modeling, high-performance control systems, reliable drive systems and a comprehensive understanding of hot rolling technology. Primetals Technologies' solutions for hot rolling are impressive for their overall efficiency. Powerful drives and reliable automation systems, in combination with precise and flexible process models, optimize the rolling process from the reheating furnace to the downstream area. Our solutions are suitable for new mills as well as for mill modernization, enabling you to create a state of the art mill and keep it there, with continuous modernization and optimization.
HOT STRIP MILL – HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS
The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way.
The production of hot strip is a key element of steel production. Since close to half of all steel produced is hot-rolled to strip, mills require maximum throughput and availability combined with geometrical precision and the ability to create optimum material properties.
PLATE MILL – POWER MEETS PRECISION…
Plate Mills are quite literally the most powerful metal-working tools on earth, but they are precision tools too – not just in terms of dimensional control but also in imparting mechanical properties to the rolled product.
Accurate microstructural control starts with expert process knowledge. Whether building a new mill or upgrading an existing one, the essence of project success is a quick ascent of the operational learning curve, and so at Primetals Technologies we combine our process expertise with a partnership approach to project delivery.
STECKEL MILL – SPECIALIZED SOLUTIONS THROUGH ENGINEERING EXPERIENCE
The Steckel Mill occupies a special niche in hot flat rolling, operating at a lower economic volume than tandem hot strip mills but capable of greater widths and especially suitable for particular alloys, including stainless steels.
Its metallurgical and process control complexity is comparable to the Plate Mill, and its design, operation and yield characteristics are highly specialized. Experience is therefore the key to Steckel Mill engineering. Whether building a new mill or upgrading an existing one, the essence of project success is a quick ascent of the operational learning curve, and so at Primetals Technologies we combine our process expertise with a partnership approach to project delivery.
PLATE STECKEL MILL – BEST OF BOTH WORLDS
The Plate-Steckel Mill is a highly specialized hybrid, capable of rolling wide structural steel products in both flat plate and coil form, and at very long lengths through the use of coiler furnaces.
There are few examples and even fewer truly successful project references, with Unisons prominent as a proven supplier. Whether building a new mill or upgrading an existing one, the essence of project success is a quick ascent of the operational learning curve, and so at Primetals Technologies we combine our process expertise with a partnership approach to project delivery.
ENDLESS ROLLING MILL - ADVANCED SOLUTIONS FROM THE MARKET PIONEERS
The concept of endless hot rolling was introduced to meet the increasing demands for hot-rolled steel sheet using a cost-effective process compared to the conventional batch-type process.
Endless rolling involves the joining of the tail end of a preceding transfer bar with the head end of the following transfer bar after the roughing stands but prior to the finishing stands. Primetals Technologies was the first company in the world to develop the related equipment for induction-heating joining (IHJ) and super deformation joining (SDJ) to enable endless rolling. Furthermore, the dynamic Pair Cross mill can also be installed to deal with flying strip-thickness changes and increasing thermal crown resulting from continuous rolling.
