Description
Invention field
The present invention relates to a kind of pickling and rolling equipment for pickling and the combination of metal band rolling.
Background technology
In cold rolling field, earliest complete continuous rolling mill (completely continuous rolling mill)
It is to be manufactured in the seventies and the eighties, is then manufactured that pickling and the rolling equipment of earliest combination.
There is significant benefit in the following areas come the benefit of continuously rolled bands by rolling welding point：Equipment is produced
Rate, wherein increased 20% to 100% in production rate per hour or the km number of rolling；Surface quality, is being supplied by reducing
The risk of defect is produced during the step of to head with the afterbody for exiting rolling；And in aspect of performance, by reducing due to super
The loss of the head and afterbody material that go out thickness and cause.
This solution is related to offer equipment, and in such devices, continuous acid-washing is directly connected to four or five
The tandem cold-rolling mill of individual rolling machine frame, cost of investment increases and with production capacity high, generally per year over 1000000
Ton.
This solution the disadvantage is that, the length based on product to be rolled every time, " bottle of the production by equipment
The limitation of neck ", according to the size and weight of coiled material, " bottleneck " of equipment be probably with by tandem milling train can show it is relative
In the maximal rate from speed obtained by each frame about and with the relevant equipment input of installation power, acid cleaning process,
Accumulation and milling train.
With reference to the requirement to increasingly lower thickness, the development of material, tolerance steel (highly resistant particularly high
Steel development) has driven the development of the new continuous rolling mill for being connected to pickling line.For example, having been carried out two
The curved arrangement of equipment so that up- coiler of the unwinding spool of pickling line near milling train.Thus, it is possible to complete to reduce, and can
With in the coiled material of the input of pickling line supply rolling, to realize the increase of the reduction quantity of milling train.This configuration have with
The shortcoming for significantly reducing correlation of production capacity, this is due to needing to provide several passages (pass) so as to complete with required thickness
Into coiled material.
The alternative solution that some manufacturers use is to roll the one kind in so-called " huge coiled material (jumbo coils) ",
In some cases, should " huge coiled material " again more than 60 tons and diameter is close to 3 meters.Used on discontinuous tandem milling train
The system progressively makes productivity ratio close to value obtained by continuous rolling mill, improves its performance, and partly improve
Surface quality.The advantage of this solution is reduction of the cost of investment for rolling equipment, but the solution is related to
For the notable cost of coiled material carrier structure (for example, road and corresponding overhead crane), coiled material carrier structure must scale
The very little upstream and downstream in equipment is continuously supporting these increased load.
The alternative solution of tandem cold-rolling mill is in reversable mill, and reversable mill is typically implemented less production energy
Power, and precisely：
- for single chassis reversable mill, be every year 100,000 ton to 400,000 ton；
- for double-stand reversible mill, be every year 200,000 ton to 1,000,000 ton.
Due to its property, rolling is related to the material for the tandem milling train with several frames on reversable mill
The poor performance of material, this is because the head and afterbody of positive rolling are not rolled or are partly rolled.Additionally, being rolled reversible
The possibility that the surface smoothness of band is exited in the control obtained such as in tandem milling train is eliminated in machine.Because not recommending
Rolling machine frame was changed before last passage is performed, it is therefore an objective to which roughness is delivered to belt surface, and using different
Emulsifying systems are come to reduce surface smut be extremely complex and expensive.
In order to improve the performance of reversable mill, various programs and innovation are had attempted to, for example：
- exploitation equipment automates to obtain the supply of head and exiting for afterbody when frame is closed with corresponding；
- offer spot welding picks, for the head of coiled material to be welded into guiding band, i.e. be welded to the band that will not be rolled
Extension, to allow on material to be produced to feed as quickly as possible and to close frame.
These technologies have been presented for partial results, this be due to its application be related to the obvious reinforcement of milling train operating condition with
And damage the possible risk of Rolling roller.
The pickling and rolling of the combination for metal tape with reversable mill are disclosed in US2012/0272703A1
The example of equipment.
Accordingly, it is desirable to provide a kind of pickling for allowing to overcome the combination of disadvantages mentioned above and rolling equipment and corresponding work
Skill.
