Wet Levelling liquid

Abstract

A wet smoothing liquid for the surface of steel plate contains composite antirust agent composed of organic acid and organic amine, the corrosion inhibitor and washing assistant composed of surfactant and water. Its advantages are excellent cleaning and antirusting power, and no pollution.

Description

Technical field: [0001] The invention relates to a wet leveling liquid used in the leveling process of the cold-rolled steel plate manufacturing process. Background technique: [0002] As we all know, the manufacture of cold-rolled steel sheets can be roughly divided into five processes: pickling, rolling, annealing, leveling and refining and oiling. Among them, rolling, annealing and leveling are the three main processes that determine the quality of cold-rolled sheets. The so-called flattening process refers to the low-deformation rolling process after the steel coil is annealed, and its main purpose is to eliminate some surface defects caused by the rolling process and further improve the mechanical properties of the steel plate. The leveling process is divided into two types: dry leveling and wet leveling. At present, wet leveling is mostly used. The current wet leveling liquid is generally dominated by sodium nitrite type inorganic wet leveling liquid, which has poor cl...
