The electromagnetic strip stabiliser strategically positions an electromagnet close to the steel sheet’s surface as it travels through the rollers. A sensor detects C-wrapping and vibration, and when it does, it turns on the magnet to maintain the sheet flat and free of movement.
The electromagnet, an eddy-current type displacement sensor, a control unit, and a power unit make up the electromagnetic strip stabiliser. The electromagnetic strip stabiliser operates consistently thanks to this straightforward design, which also makes maintenance a breeze.
Steel sheet is passed through a high-temperature (420°C or higher) solution of molten zinc alloy at a rapid speed of 2000 m/min in a molten zinc galvanising line.
The Global Electromagnetic strip stabilizer Market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The non-contact electromagnetic strip stabiliser from ABB features a special, proprietary control approach that lessens vibrations and issues with strip form, allowing for increased coating quality and decreased overcoating.
The steel strip is stabilised by the EM Stabilizer using electromagnetic force without coming into direct contact with the strip. It reduces vibrations and oscillations on galvanising lines, provides more effective air knife operation, and permits better coating control, less overcoating, and even faster line speeds.
Reduced vibration amplitude lowers the possibility of a collision between the strip and the surrounding structure when employed in the tower of a galvanising line or in other types of strip lines for magnetic steel. Three sets of water-cooled electromagnets regulated by frequency converters make up the EM Stabilizer system.
A turnkey system called EMG eMASS uses electromagnets to stabilise fast-moving ferromagnetic steel strips. The primary area of application is the streamlining and cost-saving of a hot-dip galvanising, GALVALUME, or aluminizing line’s air knife metal coating process.
As near as possible to the nozzle lip that blasts off the liquid metal layer, the system is mounted right above the nozzle. With more than 50 successful installations under its belt, EMG ensures a tailored, ideal integration of eMASS in the air knife area.
Producer of cold-rolled and galvanised coils Duferco Steel Processing (Pty) upgraded the galvanising plant at Saldanha, Western Cape province, South Africa, using Danieli Kohler zinc-pot wiping technology.
The chosen approach includes the Danieli Electromagnetic strip Stabilizer (DES) and Automatic Closed Loop Control, which will enhance the well-known Danieli Kohler X-Jet system.
High-speed low-thickness uniform coating application made possible by the X-integrated Jet’s DES technology results in the highest levels of competitiveness in terms of final quality and production costs. At 160 m/min line speed, it will be possible to achieve galvanised coatings with a total weight of 60 g/m2 on both sides.
