Abstract
The invention relates to a method for reconditioning rollers for the production of rolling mill products. According to the inventive method, the rollers are reconditioned following or during use, by treatment of the surface thereof. One such method is significantly improved in terms of related down time and costs by the fact that the surface of the roller is treated by means of a liquid jet and the hydrostatic pressure during the production of the jet is set to between approximately 50 and 250 Mpa, preferably between 70 and 150 MPa.
Description
The present invention relates to a kind of method that is used to rebuild the roll of the hot-aluminium mill frame that is used for making rolled products, wherein, rebuilding by handling the roller surface breaker roll after the use or between the operating period.
Known by prior art, be used for making the roller surface that roll has and application purpose at that time is complementary of rolled products.For example being used for the working roll of hot rolling or cold rolled metal strip has the roller surface of a band certain roughness, guaranteeing catching milling material reliably by roll, and produces the milling material surface of regulation.The roll of other types, for example backing roll, band carry-over pinch rolls or the like also have the roller surface that this roll of assurance of regulation is worked well.
Because at rolling rolled products, high pressure for example appears when band, sheet material or the like, the deposition of formation rule on roller surface, this causes the operation of rolling not move well after roll uses the regular hour again, and rolling in other words result no longer can be satisfactory.
Particularly when the hot rolling aluminium strip, form obstinate especially deposition.Working roll used when the hot rolling aluminium strip has the grinding texture in its surface, and it guarantees to make desirable milling material surface characteristic on the one hand, helps on the other hand catching milling material reliably by roll, avoids thus skidding in roll gap.When using roll in this grinding texture depression deposition of aluminium oxide or alumina particles, perhaps according to difference, deposition of magnesium or the magnesium granules of rolling alloy.These particles because high draught pressure is compressed in this wise, make their densifications and the depression that is full of the grinding texture very resistively in depression.This causes again: roll after certain service time when rolling grinding texture on the roller surface no longer work.This deposition that forms on roller surface also is referred to as roller shell (Walzhemd).
The filling of roller surface grinding texture causes different effects.Can not guarantee to catch milling material reliably by roll on the one hand, roll begins to skid again.On some position of the roller surface of working roll, gather above-mentioned particle more and more, cause the undesirable pressurized of rolling strip surface.In the part, gather the particle detachment with compacting, and stay on the strip surface as so-called adhesion bits (Pickup) than big unit.
By the different rolled products of different aluminum alloy hot rollings the time, described effect shows impression in various degree.
Because roll is the very high product of manufacturing cost, as by known in the art, they are not integral replacings after forming roller shell or the like, but remove and rebuild by processing/processing roller surface, roll has desirable performance in its surface again after trimming, and can continue to use.Known by prior art, roll is by such method trimming, promptly, roller surface machine cut method, as grinding, in this way the time, remove the dirt of certain deposition and the material of roll itself, so that produce a new roller surface from roller surface.Sometimes after machine cut was handled, roller surface also applied again or hardens.
Because owing to add in machine cut and to remove roll material man-hour and constantly reduce, roll is ultimate failure after the trimming of certain number of times, that is can not re-use after trimming in trimming repeatedly for roller diameter.This is that variation by geometrical property causes on the one hand, but also is that they are because intensity or the like is suitable for continuing trimming inadequately and no longer owing to arrived certain material layer of roll material on the other hand.
These have different problems by the known roll repair method of prior art.Roll must be pulled down and with roll replacement new or that rebuild on the one hand in order to rebuild.What cause milling train thus is very expensive downtime of pass.The trimming of the scene of roll is impossible usually in addition, and therefore roll to be rebuild must be carried long distance.Use machine cut method processing roll at last, cause the very fast loss of expensive roll.Here should be noted that the working roll in the hot rolling support for example especially owing to must repeatedly rebuild described one week of effect.
Known in addition, be provided with cleaning brush the service life for the roll that prolongs the hot-rolling mill that is used for aluminium, with cleaning brush in installment state, scrubbing brush roller surface especially continuously.At least be the formation that reduces roller surface top roll shell thus.Described brush is wire brush or plastic bruss, and its long-term use causes the variation one of roller surface to be similar to polishing, has reduced the ability of catching milling material with roll reliably thus.
From above-mentioned prior art and relevant therewith problem, the objective of the invention is, a kind of method that is used to repair the roll that is used for making rolled products is provided, this method guarantee roll easily and fast with trimming with low cost.
According to the present invention, draw the front and the purpose that proposes realizes by such method,, handles roller surface by means of a liquid jet that is, and fluid pressure adjusts to about 50 to 250MPa when producing liquid jet, and especially 70 to 150MPa.
Show that unexpectedly the particle and the deposit that accumulate in the high compaction on the roller surface can almost have no to be removed by means of liquid jet residually.Handle roller surface by means of liquid jet and have the following advantages especially, change original roller surface hardly, reducing of roller diameter therefore when trimming, for example do not occur by processing/processing.Owing to when handling, change original roller surface hardly, even roll still keeps its size constancy after trimming by means of liquid jet.Compare also very little to the requirement of handling by means of liquid jet with guaranteeing the machine cut method of dimensional stability.At last, handling roller surface by means of liquid jet can be than using the machine cut method, and as grinding, the processing roll surface is faster.But by method of the present invention also can with combine by the known machine cut method of prior art.
Adjust to about 50 to 250MPa (106Pa) according to the present invention's fluid pressure when producing liquid jet, especially 70 to 150MPa, guarantees to remove reliably residue and dirt on the roll thus.In order to produce such pressure, in most of the cases adopt mechanically operated plunger displacement pump, sometimes the assistance application hydraulic intensifier.
Method of the present invention obtains first kind of good scheme by such mode,, handles roller surface in order only to rebuild by means of liquid jet that is.Actual proof, by means of liquid jet handle roller surface with reconditioning rollers make in principle particularly become by brush subsequent treatment roller surface unnecessary.Particularly, the coat of roller surface remains unchanged when handling by means of liquid jet usually, for example the coating that applies for the intensity that improves roller surface.
Above-mentioned performance by method of the present invention can promptly be handled roller surface in the installment state of roll by means of liquid jet by such method doing improvement best aspect downtime and the workflow.By rebuilding with this roll of having mentioned, shortened the downtime of the milling train that is caused by trimming greatly by means of liquid jet high speed processing roller surface in installment state.
Owing in the operation of rolling, have discontinuously continuously and process/handle the downtime of having avoided fully in order to reconditioning rollers.
Another kind as such scheme is selected, and can advantageously improve by such method according to design of the present invention, that is, handle and carry out at rolling tempus intercalare.Usually have in the operation of rolling intermittently, this is relevant with system for example transports to the milling train place and causes that can be used for without a doubt by reconditioning rollers of the present invention these rolling intermittences owing to new ingot.
These two kinds of measures can so that the trimming job delete as by the prior art steel wire or the plastic bruss of brush roll during rolling as can be known.Roller surface further improves the service life of roll thus, because can not be subjected to wire brush " polishing ".
Because what adopt as aforesaid liquid is water, therefore further optimize aspect the feature of environmental protection, job security and the expense relevant with the method by method of the present invention.Guarantee to keep without a doubt explosion-proof by adopting water.The water that occurs during this external trimming can be handled in the framework of normal drainage measure without difficulty, perhaps can be retained in the water-flow circuit, for example in the emulsion water-flow circuit of hot-rolling mill.But according to the difference of application scenario, can adopt various alternative liquid in principle, the liquid jet that is used to handle with generation.The quality of the water that is adopted should be complementary with the application corresponding occasion.Also can consider to add the particle of corresponding dosage for certain application scenario,, perhaps change processing roll surface, shape ground to improve cleaning force.
Exist multiple different being used for rebuild the roll that is used to make rolled products by the scheme of method of the present invention and improve the possibility of structure.For this reason on the one hand can be with reference to each claim of claim 1 back, on the other hand with reference to the explanation of accompanying drawing to an embodiment.Represent in the accompanying drawing:
Fig. 1 schematically illustrates the section that amplifies greatly of a work roll surface,
The perspective view of the roll of Fig. 2 when rebuilding by means of method of the present invention.
The profile of the working roll of analysing and observe the hot rolling support that expression one is used for aluminium alloy that amplifies greatly that schematically illustrates among Fig. 1.
In analysing and observe shown in Fig. 1, roll material 1 usefulness hatching is originally represented.It under described situation a steel roll.Also can adopt for example grain roll in other application scenarios.Can be clear that, shown in the situation bottom roll surface of proportional sizes form concavo-convex profile, and have many protruding 2 and pit 3.These projection 2 and pits 3 in roll material 1 are commonly referred to as roughness, guarantee to catch milling material reliably by roll as mentioned above when working roll shown in using, and guarantee that milling material has the molding surface of hope.This incompatible assurance of friction lock by between projection 2 and pit 3 and rolling aluminium strip, forming.
Secondly Fig. 1 also represents, forms a chromium coating 4 on roller surface.The chromium coating 4 of this gross area is used for improving the hardness of roller surface, thereby improves the wearability of projection.
Roller surface shown in Fig. 1 belongs to used to a great extent roll, in this use when the hot rolling aluminium strip in pit 3 inner accumulated aluminium oxide and alumina particles, they since high draught pressure be compressed into deposit 5.Can know and see, covered part projection 2 at the deposit shown in Fig. 15, thereby reduced the clamping force between roller surface and the milling material, more and more cause thus as roll skid, the effect of deposit 5 coming off, the deposit that comes off is stayed on the milling material surface, cause the serious accumulation of deposit 5 point-like, they stay impression on the milling material surface.
In order to make complete impeccable milling material, the roller surface shown in Fig. 1 must be rebuild.By method of the present invention, trimming is undertaken by such mode, promptly, handle roller surface by means of liquid jet, as shown in Figure 2, for the working roll of the hot-rolling mill that is used for aluminium, preferably adopt water as liquid, because itself adopts a kind of water/emulsifier when hot rolling, that is to say that water is not impurity in processing procedure.
Roll 6 shown in Fig. 2 has the roller shell 7 that uses the back to be made up of the deposit shown in Fig. 15 certain, and it must be removed when trimming.
By method of the present invention, trimming is undertaken by such method, promptly handles roller surface 8 by means of the liquid jet of an ejection from a spray gun 10.Be removed by means of liquid jet 9 surface treated 11 top roll shells.
Both can also can under disassembly status, carry out shown in Fig. 2 in the installment state of roll 6 by trimming of the present invention.Spray gun 10 can be with hand or is automatically guided in addition.A device be worth to be installed in the milling train seat, it make spray gun 10 when reconditioning rollers 6 automatically the position on roller surface 8, advance definitely so that one if necessary-remove the roller shell.This also can carry out in the operation of rolling.
When the working roll of the hot-rolling mill of rebuilding-be used for aluminium alloy by the present invention, should note following problem.Described undesirable effect occurring, as before skidding or the like, one by means of in use being reduced to about 55% by the roughness of the known method of prior art by the roll of grinding trimming.By the present invention, handle roller surface by means of the water bundle and impel roughness to bring up to about 95% of original value.Thereby can make the roll of rebuilding continue to use with finding no fault with.
Adopt water bundle in described when trimming, do not add particle and handle with about 200MPa pressure.
In described embodiment, that is for being used for the working roll of rolling aluminum, actual showing, roll should be with traditional method, promptly by machine cut processing, as grinding after repeatedly rebuilding with method of the present invention, then chromium plating is rebuild, so that reconditioning rollers surface up hill and dale.After repeatedly rebuilding, need to carry out this common trimming in the above-described embodiments by the present invention.
