Description

A kind of electrolysis method scale removal equipment

Technical field

The utility model belongs to metal removal oxide skin apparatus field, sets more particularly, to a kind of electrolysis method scale removal It is standby.

Background technique

Hot-rolled steel because carrying out at high temperature, and the unavoidable steel that will cause is chemically reacted with the oxygen in air, on surface It will form certain thickness oxide skin, the general three-decker composition of the oxide skin after finish to gauge, steel matrix is respectively oxygen from inside to outside Change ferrous iron and account for about the 40%~95% of oxide skin overall thickness, is loose, porous fine crystallization tissue；Middle layer is ferroso-ferric oxide Account for about the 4%~14% of overall thickness, is fine and close, non-porous and crack glass break magnetic tissue；Outermost layer is three oxidations two Iron accounts for about the 1%~2% of overall thickness, is the iron oxide of crystal structure；Oxide skin overall thickness is generally 6.5um~15um.Due to The generation of oxide skin and developmental process are influenced by conditions such as temperature and times, so steel band is naturally cold in finish to gauge and after batching But ferrous oxide can gradually change to ferroso-ferric oxide during, the final accounting for changing oxide skin three-decker.From the above oxygen Change skin generating process to see, essence is exactly the oxidation process of iron；From the removal of oxide skin in terms of property angle, ferrous oxide is easy Removal, the high oxide ferroso-ferric oxide of mainly iron is to be difficult to remove, and people have taken a variety of methods and handled The oxide skin generated in the production process.

The processing most common method of oxide skin is oxygen caused by acid wash is removed such as the method for still pickling because of hot rolling at present Compound produces a large amount of spent acid discharge in the process, extremely serious pollution is caused to environment, right in operation Staff and its equipment damage.

In addition to traditional acid washing method, there are also traditional electrolyte method, water sand-blast, traditional brushing methods (Mechanical Method) etc..It is other It is some for example, laser, plasma etc. are even more the method for earth-free gas, although can remove or higher cost or be exactly to imitate Rate is extremely low, very impracticable；Traditional electrolyte method, water sand-blast, in traditional steel wire brushing method (Mechanical Method) each all or mostly or Few there are some problems, so that metallurgy industry, up to the present handles oxide skin, or extremely dirty using causing to environment Dye and the extremely severe acid washing method of working environment.

Traditional electrolyte method, such as CN1266650A, because export license, flow of electrolyte are big, more projection electrode spacing is excessive, So that power consumption is very big, electric utilization rate is very low, most is heated to electrolyte again, cannot solve at all in industry at present Certainly, cause this method unpractical feasibility at all.If shortening interelectrode distance, it will cause short circuits, can not carry out electricity Solution.

In particular, it should be pointed out that traditional brushing method, since traditional brushing method is in the presence of the oxidation that can not be removed in tiny pit The problems such as object and low production efficiency, is difficult to realize industrialized mass production, and bristle is that line contacts mill with steel part processed It cuts, the quality for the treatment of effect, mainly there is the number of brush roll quantity to determine, the increase of brush roll quantity is directly related to transfer motion power Size, and then influence processing cost and efficiency；The method can not preferably solve always bristle at work with the mill of steel part After damage, backlash compensation problem between bristle and steel part causes this method to fail to obtain popularization and application；In addition many traditional brushes Mill method is if it is intended to handle the oxide in tiny pit, the method for use is then hard grind of going into overdrive, so that causing convex Useful steel is also worn at rising, while the probability that brush roll is worn greatly improves, to cause to be lost excessive.
