For a continuously reliable process

Hot rolling and heavy plate production are always associated with great forces. Shock, vibration and applied forces are typical here: for example, when rolling and cooling or cutting to finished dimensions along with the accompanying inspection steps. The equipment also needs to withstand moisture on the rolling mill caused by water cooling.

As a heavy plate producer you need high-performance equipment and suitable regulating devices at every process stage. With Balluff you get first-class technology to master all the stages from the slab to the coil: fieldbus modules, temperature sensors, position measuring systems, industrial RFID systems and vision sensors.

Application examples

  • Fieldbus modules up to 70 °C for all bus systems

    Fieldbus modules up to 70 °C for all bus systems

    The solution

    Modules for use in steelworks with functional security up to 70 °C simplify your network topology. Regardless of which bus system you are using, our BNI fieldbus modules let you construct modular networks. And additionally available IO-Link versions make it possible to effectively and inexpensively wire all sensors.

    The features

    • Construct networks regardless of the controller manufacturer
    • Protection class IP67
    • Functionally safe up to 70 °C

  • Slab guidance in the rolling stand

    Slab guidance in the rolling stand

    The solution

    Compensate for the great forces created during forming safely and reliably. Our BTL magnetostrictive linear position sensors in the hydraulic cylinder are ideal for positioning and guiding the slabs. They check for the correct configuration of the lateral guides and accompany the slabs on their path through the rolling stand.

    The features

    • Protected against harsh conditions, because it is integrated in the cylinder

  • Reliable slab position detection

    Reliable slab position detection

    The solution

    Infrared temperature sensors earn their keep not only at the transition from the continuous casting line to the rolling stand. Designed for high temperatures, they also monitor – without contact – the slab transport at the reversing mill, so that the slabs can be quickly and very precisely rolled out. These sensors in the rugged M30 stainless steel housing have a multi-function display as well as an automatic display orientation and in the IO-Link version offer all the advantages of this innovative communication standard.

    The features

    • Secure detection of moving, glowing hot objects
    • Simple, self-explanatory commissioning operation
    • Available with IO-Link or analog interface
    Reliable slab position detection

  • Setting the roll gap precisely

    Setting the roll gap precisely

    The solution

    Our BTL magnetostrictive linear position sensor with IP69K protection is ideally suited for setting the roll gap with high accuracy. It withstands the extreme ambient conditions of the steel plant with absolute sealing integrity and, therefore, requires no additional protection from the continuous water cooling of the rolling stands.

    The features

    • Protection type IP69K
    • Wear-free, long service life thanks to non-contact operating principle

  • Quality assurance at the rolling stand

    Quality assurance at the rolling stand

    The solution

    Prevent errors during the process using increased automation. With the Balluff BIS M Industrial RFID system, you can automatically record and identify all tools used. This lets you quickly check whether the correct rolls are being used or whether the roll pairs match. At the same time, reworking of the rolls is documented. This consistently prevents errors and allows you to perform maintenance at just the right time.

    The features

    • RFID handhelds for mobile communication right at the plant

  • Correct assignment of slabs and coils

    Correct assignment of slabs and coils

    The solution

    Reliable reading is also possible under challenging conditions. Simply use color codes and barcodes to clearly identify coils and other products. The Balluff BVS vision sensor uses these markings to check whether slabs and coils are correctly assigned. Quickly, reliably and regardless of their position.

    The features

    • External monitor for better process tracking
    • Extensive range of accessories that meet industrial standards
