What is your product? Deformed TMbaR®?

Rebar mills are designed to produce ‘martensite-free’ products by drastically reducing microalloyed elements and transformation costs, thus improving weldability, ductility, and material homogeneity.

Wire rod? Which grade?

High-speed rolling mills are designed to obtain superb-quality wire rod – more precise than ever. They process any kind of steel grade at a low rolling temperature (750 °C) and product tolerances from ±0.05–±0.09 mm into wire rod 4.5–27 mm in diameter up to 50 % ovality (1/8 DIN 59110) at 130 m/s with MEERdrive®PLUS sizing technology.

Plant types

  • High-speed delivery mill

    Where limited investment meets higher productivity

    High-Speed Delivery (HSD®) mills ideally combine limited investment with high productivity. A solution that guarantees a fast return on investment (ROI). Generally, these mills are sized for medium range production of up to 500,000 t/y. However, we can also reach big capacities of 1.6 million t/y (245 t/h endless with EBROS® welding technology) and 2.0 million t/y (330 t/h). HSD® mills are ready for the next challenge: to reach the speeds of 60 m/s and more on small products thanks to the next generation VHSD® (Very High-Speed Delivery System).

  • Multi-flexible rolling mill

    The quick answer to economical solutions for high rolling production capabilities

    Main data

    Multi-flexible mills production can include flats, squares, hexagons, and light sections to complete the rounds and rebar production, produced at rates of over 200 t/h with over 250 products rolled into a single rolling mill. The rolling mills are characterized by lower overall  investment costs compared to a solution with one (or two) high-speed finishing blocks and the associated additional electrics, piping, and civil works. This investment is partially offset by the need for two additional convertible stands without housings for multi-strand operations.

  • Light section mill

    Great flexibility with a wide range of products

    Main data

    A modern merchant bar mill has the capacity to produce a variety of products, such as angles, squares, flats, and small channels. Round bars can naturally be produced, too. Such a mill is characterized by great flexibility and has an annual capacity of 500,000 to 600,000 t/y producing a broad product mix including plain rounds and rebars, flats, tees, angles and channels, and I-beams.

  • Special Bar Quality mill

    Meeting market requirements with flexibility and precision

    Main data

    In our Special Bar Quality (SBQ) mills we make use of the 3-roll PSM® (Precision Sizing Mill) technology – a high-precision and flexible solution for the finish-rolling of bars. With the PSM® one family, rolling in the roughing and intermediate mill as well as the infinitely variable production of all finishing sizes by using the free size range is possible.

    The high roll force capacity allows thermomechanical rolling. The subsequent pieces of equipment, such as a cooling bed as well as a pouring reel line, are consequently designed for scratch prevention. The metallurgical aspects, like fast or retarded cooling, are considered in the equipment. 

    The right product at the right time: SBQ stands for stricter tolerances, repetitiveness, and defect-free products with fast deliveries.

  • Wire rod mill

    Merging top quality, high productivity and low costs

    Main data

    The wire rod mill is an all-rounder: creating high-quality components for the automotive and chemical industries through to the mechanical engineering and many other sectors. The solutions offered by SMS group for wire rod mills are correspondingly versatile. Dimensions from 4.5 to 27 mm diameter in all steel grades can be efficiently produced on such lines. Single- or double-strand high-speed wire rod mills from SMS group roll small dimensions with high production capacities of up to more than 1,000,000 t/y. Stable and constant speeds up to 120 m/s (130 m/s and more are the next challenge) are possible. Even at full speed, the rolling mills achieve a perfect laying pattern.

  • Combined rolling mill

    Flexibility combined with higher productivity

    Main data

    A highly flexible and productive solution is the bar mill, which combines single-stand or two-stand rolling via high-speed finishing blocks and a two-strand HSD® High-Speed Delivery system. The presence of the finishing blocks easily facilitates a further extension for the production of wire rod or for the production of torsion-free coils with the VCC® Vertical Compact Coiler system. In combination with the EBROS® Endless Rod Rolling System, customized coils weighing up to 8 tons can be produced.

Technology

  • EBROS®

    Endless Bar Rolling System

    The Endless Bar Rolling System (EBROS®) is used to weld together successive billets while hot in a bar or wire rod mill line, to produce an endless rolling process. Welding is performed by the flash welding method, the properties of the welded joint after rolling are the same as those of the base material, and the joint is a saleable product. The endless rolled product is cut to the coil weights required by the customer after the cooling conveyor in the case of wire rod mills, and with the flying shear before the cooling bed in the case of bar mills. More than 10,000,000 billets have been welded together using this system.

    Benefits

    • Hourly production capacity increase up to 8 %
    • Metallic yield improved up to 2 %
    • No trimming operation required when producing wire rod (uncooled front-end and out-of-tolerances)
    • Elimination of cobbles, head and tails cropping on the rolled stock
    • Suitable for any layout application in case of new or existing plants
  • VCC® Vertical Compact Coiler

    Torsion-free wounded bar production

    The compact coil is a decisive step towards improving the packaging quality of the final product. These coils have preselected dimensions that, thanks to VCC®, remain the same for all products processed on the same line. At the same time, the compact coil format is ideal for storage, transport, and handling. This is particularly advantageous when the coils are reworked near construction sites where rebar stirrups and other reinforcement structures accumulate, especially in metropolitan areas where space is at a premium.

    The compact design of the VCC® makes it equally suitable for rebuilds and new installations. The outstanding feature is that you can change rolls and roll guides simultaneously within 20 minutes.

    Benefits

    • Torsion-free coils for subsequent cutting and bending lines
    • Up to 70 % savings in storage and logistics (based on a 2-ton coil weight)
    • High coil density: 80 % steel, 20 % air
    • Very compact and good coil shape for a significantly reduced storage space. From 15–17 t/m2 vs traditional wire rod coil 2–2.5 t/m2
    • Smooth and easy de-coiling operation
  • TMbaR® thermomechanical rolling for rebars

    Produce cost-effective, high-strength ‘martensite-free’ deformed bars

    SMS group has been a pioneer and promoter of the thermomechanical rolling process for decades. Today, a new chapter is being written with the application of this concept to the production of rebars. Thermomechanical rolling of reinforcing bars – known as ‘TMbaR®’ – offers the advantage of producing fine-grained structural products while reducing the manganese content in the rolled material. The exceptional ductility properties of seismic grades (e.g. HRBF400E) can only be optimized at this level by thermomechanical rolling.
