1 Steckel Mills Steckel Mills Creative solutions for the metal industryHOT ROLLING MILLSSMS metallurgySteckel MillsSMS DEMAG2 SMS Demag AGdraws on a long history as a part-ner of the iron, steel and nonferrous metal indus-tries. It began as early as 1856 when a forerunnercompany built the first rolling mill. Since then, wehave developed into a global-player group . That show decades of know-how and experience havemerged into a performance and innovation strengththat shapes the future, yet builds on corporate has coincided with steady progress in the steel industry and its production processes in recentyears.

2 Next in line were more efficient and eco-friendly technologies that have replaced traditionalmethods. We played our part in this transformationwith market-molding our group holds a leading position in interna-tional machinery and plant construction for the steeland aluminum industries. We have systematicallyexpanded our product range, so now it covers theentire process chain of metallurgical plant and rollingmill technology from steelmaking plants and contin-uous casters through hot and cold rolling Mills tostrip Technologieswas founded in 1923 as Tippins& Springle, Inc.

4 You gain a great deal fromthis joint venture. Why? Because it combines thetechnologies of SMS Demag and Tippins to providethe world s best Steckel mill technology. Even more,it boasts the longest reference list of Steckel millsaround the globe. Included in the product range areliterally all steel grades from carbon steels to stain-less steels to super alloys in sizes from medium strip to wide coil an added extra, you receive a valuable key to the success of your project. Typically, SMS DemagTippins applies its creativity to solve complex prob-lems yours too.

5 What you get is an array of solu-tions that meet your technical requirements as wellas your Demag Tippins offers you mechanical equip-ment complete with the latest process automationsystems, electrical controls and fluid systemsdesigned as units that complement each means you can expect plants that produce first-class products at competitive your goal whether improved productquality, enhanced productivity or the capacity tomanufacture higher added value products, the expe-rience and know-how of SMS Demag Tippins arevital to your is what you will gain.

Next,a four-high reversing stand rolls the transfer bar to thedesired finished strip thickness in 5 9 passes.

7 Tokeep the material hot during the rolling process, thestrip is coiled after each pass and transported into oneof the two Steckel furnaces arranged on the entry andexit sides. The heat in the furnaces maintains the striptemperature at a high plant configuration isideal for the cost-effective production of hot strip with an annual capacity of 100,000 1,000,000 noting is that the roughing stand is not neces-sary if medium-thickness slabs are actuators such as hydraulic cylinders for thickness control and CVC plus technology for controlling profile and flatness are used in today sSteckel Mills to achieve product tolerances comparableto those of modern conventional hot strip can see quite a lot of Steckel Mills featuring thiskind of configuration that we successfully built inrecent years for the cost-effective production of stain-less and acid-resistant stainless is
