Auslauf Wärmebehandlung nach Verzinken

Nach dem Eintauchen in ein Zinkbad bewirkt das Wiedererhitzen des beschichteten Stahls, dass das Zink in das Stahlsubstrat einlegiert. Das ungewisse und sich schnell ändernde Emissionsvermögen an dieser Stelle macht herkömmliche Thermometer sehr ungenau.

Der SPOT GS liefert nicht nur genaue Temperaturergebnisse, sondern gibt auch den Zielemissionsgrad aus, der das Ausmaß der Galvannealreaktion angibt.

    • SPOT GS - Temperature Measurement of Galvannealed and Galvanized Strip
      AMETEK Land SPOT GS - Temperature Measurement of Galvannealed and Galvanized Strip https://youtu.be/leNO8JclWsg

      SPOT GS enables automated furnace management to provide close control of the reaction and position of the reaction zone, delivering tighter control of product quality. By maintaining control of the reaction zone, SPOT GS accommodates rapid changes of line speed and furnace power with changes of substrate or coating weight. This allows furnace optimisation; reducing heating costs, maximising throughput and avoiding excessive over-reaction and powdering or flaking of the coating during subsequent forming operations.

      Advances in Non-Contact Temperature Measurement for Continuous Annealing and Galvanizing Lines https://youtu.be/CJFGqgTUXZ0

      We introduce how advances in accurate non-contact temperature measurements for continuous annealing (CAL) and galvanizing (CGL) lines ensure required metal characteristics and surface conditions are achieved in steel production. We will then focus on the SPOT GS, an advanced non-contact infrared spot pyrometer specifically designed for continuous, highly accurate measurements of coated steel strip temperature during the galvanneal reaction.
