Description
Technical field
The present invention relates to a kind of wet-leveling liquid composite and uses thereof.
Background technology
The production process of cold-rolled steel sheet is generally through overpickling, rolling, annealing, smooth and finishing five operations.Smooth is the cold finishing stands carried out under certain draft after band steel recrystallization annealing, and this operation determines the configuration of surface of finished strip, plate shape, mechanical property and processing performance to a great extent.Flattening process is divided into dry smooth and wet jetting piles two kinds, adopts temper rolling technology at present more, namely adopts wet-leveling liquid to affect surface quality to prevent surface of steel plate from scratching.Wet-leveling liquid can be divided into inorganic type (nitrite) leveling precision and organic type (organic amine salt) leveling precision two kinds, because nitrite compounds has certain damaging effect to human body, so current wet-leveling liquid is most based on organic type (organic amine salt) leveling precision, this type of leveling precision has good lubricity, cleaning performance and rustless property.
Also describe respectively in patent CN102286749A disclosed in wet-leveling liquid and CN102002714A and utilize organic acid and organic amine is composite reaches antirust effect, utilize the interaction of polyethers and water-soluble extreme pressure lubricant to reach processing requirement more than 3.0% draft in formation process.But up to now, in reported all China and foreign countries wet-leveling liquid patent, all do not introduced with regard to its resistance to frost, usually common wet-leveling liquid pour point is at-9 DEG C, but because northern wintry weather is cold, cause this type of wet-leveling liquid to freeze can not normally use, therefore require that wet-leveling liquid has good resistance to frost on the basis of original formulation.
