Maximum flexibility for various formats
As efficiency increases, so do the demands on continuous casting lines. Large forces, vibrations and shock have to be controlled in the continuous casting line: at the ingot mold movement for the homogeneity of the fluid metal or at the walking-beam for transport of slabs or billets. Comprehensive monitoring measures are, therefore, indispensable.
But the investment pays off, because only in this way can you prevent costly pouring interruptions before they happen, improve the quality of the product, and increase your offering variety.
The steel quality is determined at the continuous casting segments. The desired properties are achieved depending on the gradient, temperature and time of the reshaping. Therefore, maximum flexibility and peak reliability are required for the technology. Balluff sensors and systems provide you with security and guarantee a continuous process for a wide variety of product formats. Thanks to automatic format changing, every new customer requirement can be responded to in no time
The casting ladle movement requires peak reliability. And for safety reasons, all of this argues for multiple redundancy of the systems used there. Multiple redundant BTL magnetostrictive linear position sensors provide up to three independent measuring systems in one housing to meet all the requirements for safe operation of your continuous casting line.
Regulate your processes reliably from the very beginning. Our BMF magnetic field sensors help you, among other things, in regulating the process start and give you the security that the position for the sprue on the casting line has been detected precisely and reliably.
The Balluff Rapid Replacement Module allows you to quickly and easily replace BTL magnetostrictive linear position sensors in hydraulic cylinders. Since the complete sensor unit is replaced together with the integral waveguide, the hydraulic circuit remains closed. This minimizes the risk of leaks and prevents dirt from entering the hydraulic system.
Protective enclosures for photoelectric sensors directly on the casting line are a sensible addition. The advantage: the sensors used do not have to withstand elevated temperature demands and are also able to handle temperature spikes should the system go down. This is because you can equip the protective housing with water cooling. Also, optional is a blower for preventing the buildup of dirt and contaminants.
Our photoelectric distance sensors are the optimum solution for measuring at the cooling section. There they check for the correct length of the cut slabs or billets with high precision. The exact length is monitored using the difference between two sensor results.
Precise location monitoring and continuous guiding of rotary movements are critical when transporting slabs. BSI inclination sensors are an outstanding solution to this challenge. On the walking beam they measure the deviation from the horizontal line on an axis by up to 360° – non-contact and with the highest precision.
