Abstract

Verfahren zur Verringerung der Korrosivität von Kühl- oder Prozesswasser, bei dem es aufgrund eines Eintrags von Säuren zu einer Absenkung des pH-Werts kommt, dadurch gekennzeichnet, dass man zu dem Kühl- oder Prozesswasser mindestens ein wasserlösliches Salz mit puffernder Wirkung zudosiert. Vorzugsweise erfolgt dies entweder mengenproportional oder in Abhängigkeit vom Messwert einer charakteristischen Leitgrösse. Das Verfahren ist anwendbar auf Durchfluss- oder Kreislaufsysteme und kann speziell bei Strangussanlagen in der Stahlindustrie zur Anwendung kommen.
