A carousel reel will finally coil the rolled cold strip. In coupled mode with the continuous pickling line the annual capacity will be 850,000 short tons (0.77 million tons).
The skin-pass mill for post-treatment of hot and cold strip with priority at cold strip skin-passing is designed for an annual capacity of 440,000 short tons (0.4 million tons).
For cold and hot strip galvanizing, the plant will be equipped with a continuous galvanizing line including a horizontal Drever furnace heated by a direct-fired and a radiant-tube zone. The line will be prepared for the later installation of an ultra-fast gas cooling section to allow for future production of high-strength steel. The scope of supply also includes a DUMA-BANDZINK air knife system that will homogeneously and precisely set the zinc layer thickness to ensure high surface quality. A change system with two zinc pots will permit the strips to be coated with a conventional zinc layer or an aluminum-zinc alloy. For post-treatment, the line will be equipped with a four-high skin-pass mill stand, a tension leveler and two horizontal shuttle-roll coaters, as well as with an oiling machine in the exit section. The galvanizing line will be able to process strips with a thickness of up to 0.16" (4 millimeters) and a width up to 76" (1,930 millimeters). Its annual capacity will be 550,000 short tons (0.5 million tons).
For the complete technological part of the new plant complex, the X-Pact® electrical and automation systems included in the supply scope are an important factor. They assure that productivity, production flexibility and quality of the final products will meet actual and future requirements. The applied concept and equipment provide a solid foundation for the digitalization of the plants and processes and for future-oriented extensions and applications. Diagnosis and visualization concepts will be used in the entire plant. They assure and sustain effective and preventive maintenance activities.
SDI intends to sell the products in the rapidly expanding markets of high-strength steel tubes, multi-phase steels for vehicle construction and structural steels for various applications. SDI will become the leader for this new type of minimill for the production of hot strip. In particular, it is the new, extremely high-performance continuous caster in combination with the proven thermo-mechanical rolling process that will allow the production of special steels in unprecedented dimensions.
Mark D. Millett, CEO of Steel Dynamics, Inc., says: “The leading position in technology and the longstanding partnership between SDI and SMS group were the decision-making factors for awarding the order to SMS group.ˮ
Burkhard Dahmen, CEO of SMS group, says: “Steel Dynamics and SMS group have successfully completed numerous highlight projects in the past. In constructing the new plant complex in Sinton, Texas, we continue our fruitful and trusting partnership. The new project will once again illustrate the position of SMS group as Leading Partner in the World of Metals.ˮ
Steel Dynamics, Inc. (SDI), headquartered in Fort Wayne, Indiana, is one of the largest steel producers and metal recyclers in the United States with production facilities located throughout the United States, and in Mexico.
