Treatment process for limiting the oxidation of the edges of a hot rolled steel sheet coiled at the exit of the hot strip mill

摘要

Excessive oxidation of coiled hot rolled strip edges is prevented by spraying a powder onto the coil sides to form a solidified airtight film. A treatment process for restricting excessive oxidation of the edges of coiled hot rolled strip comprises spraying, onto the coil sides, a powder which solidifies and ensures air-tightness of the spaces between the coil windings. An Independent claim is also included for a glass powder for use in the above process.
