Description
Technical field
The present invention relates to a kind of devices for reducing emulsion system chloride ion content, belong to cold mill complex relevant device technology
Field.
Background technique
For plum mountain steel cold rolling mill since 09 year goes into operation, the corrosivity that emulsion itself has causes emulsion pipeline to present
Seriously corroded, trommel have weekly the phenomenon that leakage, and the sign that the surge of variation has booster to rupture passes through
Annual overhaul replaces injured pipeline and offline magnetic filter shutter, to replaced sample by means of amplification
Mirror and microscopically observation, there are a large amount of thin in region near pipe leakage point and magnetic filter shutter rotten place
Micro-crack, macroscopic observation also found, remove outside the weld seam oxidation corrosion nearby of pipeline weld, inner surface of pipeline and rotten magnetic
Property filter shutter be all also attached with white or transparent deposit, in the fracture surface of cut and pipeline crack by one layer
Oxide etch product is covered, rear to carry out energy spectrum analysis by inspection again, is determined and is contained higher chlorine in oxide.Passing through
After the above detection and analysis, researcher fixes in direction on fearful chlorine element.Due to the particular arrangement of cold mill complex,
Emulsion system arrives process in the rear of HCL acid cleaning process, since during the rolling process, bringing into for chloride ion is inevitable,
Emulsion maintenance personnel originally assert in pipeline have chloride ion can not be fearful, as long as being strictly controlled at less than technique most
Big chlorinity 60mg/L cannot become problem, then using the circulation measure of falling case, by containing high chloride ion in the part with case
Solution is imported into reserve tank, and is temporarilly reduced with this with the chloride ion content in case lotion, however allows tackling key problem team load
The problem of pipe leakage of the heart, occurs, and pipeline constantly leaks, and tubular service becomes General Maintenance, not pipeline memory situation
How, all its venting safeguards pipeline, to cause the waste of lotion and increase the improvement of environment.In improvement
Before, it can only be safeguarded in Dao Xiang, but the chloride ion that case is taken away is limited after all, and due to the production process in rolled sheet metal
In can bring new chloride ion into from preceding working procedure again, be dissolved in after emulsion and can be continuously increased corrosive pipeline degree, system pipes
The resistance to corrosion in road is actually limited after installing, can also be when chloride ion content is higher (>=60mg/L)
There are sheets and block-like black mottling to remain in belt steel surface for belt steel surface after annealing, thus, the effect of such way
It is undesirable.
For a long time, the above problem can not solve at all always.How effectively to solve chlorine in emulsion system pipeline from
Sub- content becomes key.Here is the related patents retrieved by Chinese patent, and " a kind of inhibition circulation is cold by CN03147995.2
But in water chloride ion corrosion method " disclose it is a kind of inhibit chloride ion corrosion in recirculated cooling water method, be containing chlorine from
0.5-1.8 times of sulfate of chlorine ion concentration is added in the recirculated water of son, is passivated stainless steel surface completely, and resistance is added
Dirty dispersing agent controls fouling, and the method provided converts pitting problem of the reluctant chloride ion to stainless steel to tractable
Sulfate radical is to the etching problem of carbon steel, however extra SO4 2-Secondary pollution can be generated to emulsion.In addition,
CN201010131002.6 " method for reducing chloride ion content on surface of pickled steel strip " discloses a kind of reduction pickled steel strip surface
The method of chloride ion content is increased rinsing strip process between pickled steel strip process and drying strip process, is floated using water spray
It washes and strip is rinsed first, then will be rinsed in five sections of rinse cycle casees of strip input different temperatures, reduce chlorine in rinse water
The content of ion, chloride ion content can be reduced to 15mg/l hereinafter, making belt steel surface without sour matter, after improving cold rolling of strip steel
Surface quality；It does not say first and 5 sections of different temperatures rinse cycles of strip is unfavorable for controlling, temperature control is at high cost, and is directed to band
Steel supplied materials thickness >=3mm, strip pickling speed control, can be because of strip speeds in the producing line of 150~200m/min thin plate rolling
It is too fast to cause the residual acid of plate face to enter in emulsion system to make chloride ion content excessively high and cause to corrode, hence it is imperative that one
New method is planted to solve.
Summary of the invention
