The steel plant continuous annealing line leveling liquid has good rust resistance and good lubricity.
Description
Technical Field
The invention belongs to the technical field of wastewater treatment, and particularly relates to a steel plant continuous annealing line leveling liquid, a preparation method and application thereof in steel leveling.
Background
The leveling of the steel plate after annealing is divided into a dry leveling mode and a wet leveling mode. After annealing, a large amount of fine iron powder, residual carbon and other contaminants remain on the surface of the steel sheet. In the leveling process, residues on the surface of the steel plate are effectively cleaned by the leveling liquid through flushing of the leveling liquid, so that the residues such as iron powder, residual carbon and the like on the surface of the steel plate are effectively removed, and the surface quality of the steel plate is effectively improved. Meanwhile, because a certain time is needed before the leveled steel plate enters the next working procedure, the rust resistance of the leveling liquid to the steel plate is also one of important factors required by the leveling liquid. Because the steel plate has a small reduction amount in the flattening process, the steel plate has the defects of slight surface scratches and the like in the flattening process if the flattening liquid does not have proper lubricity although the reduction amount is small. Therefore, the leveling liquid must have good cleaning property, rust prevention property and less lubricity, and also satisfy the field process condition, and the leveling liquid is a high-quality product.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention aims to provide the steel plant continuous annealing line flattening liquid which is good in rust resistance and lubricity.
The second purpose of the invention is to provide a preparation method of the leveling liquid for the continuous annealing line of the steel plant.
The invention also aims to provide the application of the continuous annealing line leveling liquid in the steel plant in steel leveling.
The leveling liquid for the continuous annealing line of the steel plant is prepared from the following components in percentage by weight:
preferably, the leveling liquid for the continuous annealing line of the steel plant is prepared from the following components in percentage by weight:
the principle of the formula of the invention is as follows: the triethanolamine phosphate and the dipalmitoyl-L-A-phosphatidylethanolamine have an antirust effect, the triisopropanolamine cyclic borate has a lubricating effect, the D-aminopropanol has the effects of a solubilizer and a cleaning agent, the sodium gluconate has the effects of a complexing agent, a corrosion inhibitor and a scale inhibitor, and the dipyridamole has an anti-aggregation effect, so that the leveling liquid is prevented from aggregating on a steel plate, and the antirust film layer is not uniform.
The preparation method of the leveling liquid for the continuous annealing line of the steel plant comprises the following steps:
weighing the components, blending, stirring and dissolving uniformly.
The application method of the leveling liquid for the continuous annealing line of the steel plant comprises the following steps:
preparing a working solution: when in use, the stock solution of the leveling liquid is diluted by adding tap water, and the water dilution ratio is generally 1: 20-30 ℃, heating the bath solution to 20-45 ℃, and enabling the strip steel to pass through the bath solution at a constant speed.
The invention has the following beneficial effects:
the steel plant continuous annealing line leveling liquid has good rust resistance and good lubricity.
