Excellent start for the hot-strip plant at the new NMDC steel plant in India
NMDC Steel Ltd. relied on thin-slab technology to enter the steel production business. The new hot strip mill is part of the new NMDC steel complex, located at Nagarnar, in Chhattisgarh, India, and it is designed to produce 2.9 million tons per year of hot-rolled coils, in strip thicknesses ranging from 16 mm down to 1.0 mm, widths from 900 to 1650 mm, in coils weighing up to 35 tons. This is the first steel plant in India featuring vertical-curved casters and a hot-strip mill with separation between roughing and finishing.
Advanced continuous casting with an innovative solution for mould level control
The recent development of a mould level control technology is considered as a ground-breaking model for establishing the ideal caster roll geometry already at the design stage. It utilizes advanced mathematical methods for next-level caster-design optimization and reduces unsteady bulging by 50 percent. As a result, it allows for higher casting speeds and greater productivity while producing slabs of reliable and high quality.

Long-term experience of active chatter damping at cold rolling mills
Chatter management can be understood as a basic concept to operate a rolling mill at low vibration levels in order to achieve maximum speeds and production. Among the tools and measures necessary to reach this aim are a chatter monitoring system and an active chatter damping system. An overview from the general idea of the system up to operational and long-term results of the pilot installation is given. Especially by the demonstrated operational results, the great potential of active vibration damping for cold rolling mills is shown.
thyssenkrupp Steel decarbonizes batch annealing plant
Bell-type annealing plants have so far been mainly operated with natural gas. Recently, 70 t of steel strip were fossil-free heat-treated in a bell-type annealing plant at German steel strip manufacturer thyssenkrupp for the first time in the world. In production trials, the fuel gas supply for the annealing plant was gradually shifted from natural gas to up to 100% hydrogen to assess the influence of increased hydrogen admixtures on the overall system. Up to 2600 kg of CO2 can be saved per annealing cycle by using regenerative produced hydrogen, while maintaining productivity and product properties.

Sustainable Steel Application and products
Low carbon-emissions rails
Rail transport is already considered climate-friendly. However, rails produced from low-CO2 steel enable rail network operators to drastically reduce their carbon emissions even further. The French subsidiaries of the Saarstahl Group, Saarstahl Rail and Saarstahl Ascoval, are currently the only providers throughout Europe to have scrutinized conventional processes and production methods, and then develop decarbonized rails. In close alliance with the state-owned railroad operator in France (SNCF - Société Nationale des Chemins de Fer Français), Saarstahl Rail has been successfully implementing the low-CO2 rail concept in practice. In the meantime, further railroad network operators and infrastructure firms have awarded Saarstahl Rail contracts for “green” rails worth millions of Euros.

Steel technology
On the way to zero waste and zero emissions - an approach to environmentally sustainable long products
Feralpi Siderurgica in Lonato del Garda (Brescia, Italy) is modernising its long products rolling mill. The company is implementing a "hot charge", i.e. a direct link between the continuous caster and the rolling mills. The project envisages a continuous and direct uninterrupted flow of billets from the continuous casting machine directly to the rolling mill, with minimum energy losses and elimination of the gas reheating furnace. This solution completely eliminates direct CO2 emissions. The hot charging technology is complemented by the welding of the billets before they enter the rolling mill, thus allowing the continuous rolling of a single billet instead of several billets. The additional benefits of this approach are reduced waste, increased productivity and higher plant utilisation.

Transformation project in Saarland goes into implementation
The Stahl-Holding-Saar Group with its subsidiaries Dillinger, Saarstahl and ROGESA has specified the transformation project and awarded the contracts for the new metallurgical equipment – the direct reduction plant and the two electric arc furnaces. Following the funding commitments from the federal and state governments for the largest European decarbonization project, the orders for the new production facilities are important milestones on the way to the “green” future of the Saarland steel industry.High-definition flatness correction for rolling mills
Through 45 years of evolution, the Integral Solenoid Valve (ISV) spray system from Primetals Technologies has become the industry standard for cooling, enabling rolling mills to achieve optimal flatness. Applying zone cooling and lubrication across the width of the work rolls addresses residual flatness errors and controls the bulk temperature of the mill during the rolling process. The new ISV Electric Compact valve pushes the technology further by increasing the flow rate control from ten discrete cooling levels up to a possible 120 levels, all within a narrower 25-millimeters zone width – delivering true high-definition control.Higher process security at the strip oiling machine
Limax has developed a new modular electrostatic oiling machine for metal strip. The machine combines the proven atomization system based on secondary electrodes with a flexible width adjustment system, a new, integrated smoothing roller, and an inline oil film measuring system from Amepa. This unique combination of components guarantees a perfectly uniform oil film, while markedly reducing oil consumption and providing operators the security that they are instantly alerted by the system in the event of overoiling or dry stripes.Optimizing performance and improving efficiency in roll grinding
Grinding of work rolls is a critical process, helping to maintain the accuracy of roll dimensions, surface quality, and the integrity of the roll — which are all essential to achieving high-quality, consistent results in production. Achieving success in roll grinding requires careful attention to several factors. Proper alignment, reducing vibration and selecting the right grinding wheel for the specific roll material are key to producing an even surface without introducing new imperfections. It is important to choose the right solutions that can help provide faster material removal rates, longer wheel life and fewer wheel changeovers.HÜTTENTAG 2024
