Technical field
The utility model relates to a kind of electrolytic clean unit, refers more particularly to the electrolytic clean unit in the degreasing process in a kind of cold rolled strip aftertreatment flow process.
Background technology
Cold-strip Steel Surface has a large amount of dirts, and its main component is grease, dust and iron powder, and the single face total amount is generally up to 300-600mg/m
2For guaranteeing the strip quality of the flow processs such as cold rolled strip subsequent anneal, zinc-plated and color coating, usually need through degreasing process.Generally adopt first the mode that alkali soaks and alkali is scrubbed to remove the belt steel surface surface contaminants in the degreasing process, but alkali immersion and alkali are scrubbed and can't be cleaned belt steel surface fully, reason is through rolling rear surface certain roughness to be arranged with steel, many greasy dirt particles and foul particle stick in the pit of belt steel surface, be difficult for thoroughly removing, the normal method of electrolytic degreasing that adopts is removed this part dirt in the actual production.
Electrolytic degreasing is to adopt electrochemical method to carry out degreasing, generally is that the band steel is immersed in the electrolyzer, load onto electrode in the band steel both sides of soaking simultaneously, and pass to direct current, when the electrode band polarity chron, with steel can because of induction with the upper polarity opposite with electrode.When electrode was negative polarity, the band steel was straight polarity.Otherwise when electrode was straight polarity, the band steel was negative polarity.No matter but the band steel is straight polarity or negative polarity, all can separate out a large amount of gases.Mechanism is as follows:
The chemical process of electrolysis is actual to be the process of brine electrolysis, water decomposition occurs, namely in solution
4H
2O = 4H
++4OH
-
At negative electrode following reaction occuring, separates out hydrogen:
At anode following reaction occurs, precipitated oxygen:
Along with a large amount of generations and the effusion of belt steel surface gas, gas can force with the dirt in the steel pit and leave the band steel, has so just played the effect of degreasing.
Electrolytic cleaning mode commonly used is that (current density is less than 50A/dm for employing low current density mode in the production
2), the following problem of normal appearance in the production:
Electrolytic solution is full of cell body, and dip-roll roll neck place needs intact tightness system, and the easily wearing and tearing of this device can affect because of expanding with heat and contract with cold sealing effectiveness in addition;
Electrolytic solution is full of cell body, contact fully with cell body, so the electrolytic cell body inwall needs line with rubber, but along with time lengthening line with rubber layer is easily aging damaged, affects electrolytic efficiency;
Battery lead plate is consumable accessory, but the restriction that arranged by existing structure need to be cut off the band steel during replacing, therefore changes difficulty;
Because cell body is full of, can increase the weight of electrolytic solution input tube " water attack " phenomenon during shutdown, damage easily pipeline and correlate meter;
When the band steel left cell body, the dirt that the cell body electrolyte inside suspends easily caused the secondary pollution of band steel.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency for above-mentioned existence, provides a kind of simple in structure, need not strict seal, install and remove easy, can be to do not cause the liquid cavate electrolytic clean unit of secondary pollution with steel.
