Compositions for the water side treatment of high heat flux copper molds

Abstract

A composition for inhibiting oxidation and corrosion of a copper surface and/or removing oxidation and corrosion byproducts on a copper surface contains at least one copper corrosion inhibiting compound, at least one polymer dispersant, and at least one chelating agent, wherein the at least one chelating agent is included in the composition in an amount of from 0.1% to 10% by weight of the composition. The composition is applied to the copper surface, either as is or in a solution with purified water, and thereby inhibits and/or cleans corrosion such as copper oxide from the copper surface. The composition may be included in cooling water provided to a copper mold in a continuous casting process, or in an offline cleaning or storage campaign.
