Tata Steel Shotton Makes Substantial Savings With Strip Stabilisation System EMG eMASS

In November 2018 the projects and hot-dip galvanizing team at Tata Steel’s Shotton site and EMG successfully completed the installation of an electromagnetic strip stabilization system EMG eMASS at the HDG #6 line. The EMG eMASS system, in this installation equipped with 6 pairs of individual moveable magnets was installed above an air knife already in production use for a longer time. The installation situation above an existing air knife is always somewhat difficult, above all because of the crane paths to be kept free for removing the pot roll. The solution here consists of a combination of movable system supports and height-adjustable magnet housings, which ensure accessibility of the nozzle system for maintenance purposes without removal of the EMG eMASS structure itself. Due to the excellent teamwork between the engineering and projects department at Tata Steel and EMG as well as with external contractors the commissioning went like clockwork. From approval to successful commissioning, the project had a duration of one year.

The combination of EMG eMASS and the additional EMG eBACS system for contact free lateral strip edge detection and baffle blade control ensures highest coating quality at full throughput. This investment reflects Tata Steel’s commitment to developing high end products for customers and sustainable production.

Mr Simon McCormick, Site Development Projects Manager, said that “The primary purpose of the strip stabilizer is to hold the strip flat as it passes through the air knives. Once fully optimized, the new device will not only control the amount of zinc deposited onto the strip and improve the coating consistency, it will also reduce how much is used and lead to substantial savings depending on the price of zinc and the product being produced.”

Shotton Works is located in Deeside, North Wales, in the UK and manufactures approximately 500,000 tonnes of metallic and pre-finished steel per year for building envelope, domestic and consumer applications.
