Definitions

  • the present invention relates to a finishing line for a metallic product according to claim 1.
  • a usual metal product finishing line (such as bands or scrolling plates) can receive at its input a mixture of oxidized or pickled products, but do not transform the oxidation state of said products such as a line stripping would.
  • a skin pass mill or a leveler which are equipment generally integrated on a finishing line only partially absorbs a layer of oxide of a product and cannot replace a real process of complete stripping on a line. dedicating to it.
  • pickling of an oxidized product is carried out in a pickling line separate from the finishing line.
  • a pickling line for a company with a metal product finishing line (for example for leveling operations, skin pass mill, various shearing - edges / lengths / etc. -, slitting, inspection, winding / unwinding, reel division, etc.)
  • a stripping line installed as a complement to its finishing line involves considerable additional costs and considerable winding / unwinding, transport logistics and operating resources between the two lines.
  • Said pickling lines generally include tanks of acids or bases dedicated to the pickling process and which are brought into contact with the product moving through said tanks.
  • pickling lines and methods include means for pickling by mechanical, vibratory or optical abrasion.
  • mechanical abrasion systems are known and described under KR20120074154A , US7601226B2 , US8062095B2 .
  • An ultrasonic vibratory abrasion system is known and described by KR20030017013A .
  • a laser abrasion system is known and described by EP0927595A1 .
  • a finishing line for a metal product, such as bands or plates, including a pickling system is presented through FR2427855A1 , said system being disposed at a periphery of at least one inlet or outlet of the product of at least one of the finishing equipment making up the finishing line.
  • FR2427855A1 does not, however, specify if and how a finishing line entry that would receive mixed products of the oxidized or pickled type manages the pickling.
  • the aim of the present invention is to make it possible to simplify logistics and to minimize or even eliminate transit, storage and coupling installations between a finishing line and a stripping line, knowing that a finishing line has no on the one hand no main pickling function and on the other hand necessarily no obligation to pickle if the incoming product is pickled.
  • a metal product finishing line is thus proposed through the characteristics of claim 1.
  • a set of sub-claims also presents advantages of the invention.
  • a finishing line operator can thus, for products exhibiting obvious oxidation, allow his product to pass through the stripping system inserted and activated in the finishing line in order thus to avoid said operating problems, logistics, transit, coupling of the aforementioned lines.
  • a simple bypass circuit or even a stop of the active pickling function of the product in transit in the pickling system is initiated.
  • finishing line input receives mixed products of oxidized or pickled type
  • said type can be identified in order to switch the pickling system under an activation or inactivation mode.
  • feed a finishing line according to the invention with non-pickled products and to cause a finished processed product to exit downstream from the line by the means of said line, that is to say with a stripped or non-stripped surface according to the operator's request.
  • a finishing line comprising a pickling system which is free of acid, base or salts (acid or base salts) dedicated to pickling proves to be a preferred embodiment, if this category of system stripper comprises an interruptible stripping means, such as systems based on at least one mechanical, vibratory or optical stripper.
  • an interruptible stripping means such as systems based on at least one mechanical, vibratory or optical stripper.
  • the stripping system can be easily and frequently switched operationally according to flexibility needs linked to an order book to be produced, in active or inactive without a transient phase linked to the flow of products entering or even stopping products of various types in successive scrolling.
  • Productivity can thus be greatly increased and the type of product treated by a single finishing line will be considerably extended allowing a much greater and faster return on investment than on finishing lines previously offered without stripping.
  • the stripping system is activated or deactivated according to information by operator, file or recognition on the oxidation state of the product at the input of the finishing line, said information being delivered to a control module of the stripping system .
  • Preferential arrangements of the stripping system in a finishing line consist in placing it downstream or upstream of a leveling equipment of a finishing line such as a pre-leveling machine, a skin pass mill and / or a leveler.
  • the finishing line according to the invention provides that the pickling system is preferably free of acid, base or salts (acid or base salts) dedicated to pickling, ideally by a spraying system on the product of a stripping compound such as by means of an abrasive solid material and, if necessary, an assistant liquid.
  • the abrasive solid material may comprise particles and / or solid grains (such as metal shot, sand, etc.) and the liquid, if necessary, comprises at least water.
  • the liquid can also or alternatively comprise at least one oxidation inhibitor.
  • the system for spraying the product can then comprise at least one turbine for ejecting the pickling compound.
  • the spraying system on the product can comprise at least one nozzle or diffuser / spray injector supplied with the pressurized liquid and the abrasive solid material.
  • Said projection systems are arranged by local insertion into the finishing line at at least a single location or several successive locations, or even delocalized around the initial finishing line equipment, so that their arrangement is as compact as possible in order to to keep the size of the minimum / original finish line.
  • the pickling system is free of acid, base or salts (acid or base salts) dedicated to pickling, ideally by at least one electromagnetic emission system such as in the optical range of laser radiation scanning by continuous vaporization impact on the product surface and / or electromagnetic radiation can also be generated by the effect of high power laser radiation as described in EP0927595A1 .
  • Such a system is very compact and can be easily inserted, arranged in numerous locations at the entry and / and exit of the finishing equipment. High stripping power is achieved by increasing the number of these very compact stripping systems along the finishing line.
  • the finishing line according to the invention can provide that the pickling system is free of acid, base or salts (acid or base salts) dedicated to pickling, ideally by at least one generator vibratory system. ultrasonic waves acting in a suitable liquid tank such as water in which the product passes.
  • the stripping system ideally free of acid, base or of salts (acid or base salts) dedicated to pickling, inserted only requires a few meters in length and can also be easily inserted between the equipment of the finishing line (unlike the acid tank of several tens of meters in a scrolling stripping line of comparable scrolling speed).
  • the finishing line provides that an introduction of an oxidation inhibitor to the pickling system can be activated, modulated or inactivated as a function of information on the desired duration of the maintenance of the state. excluding oxidation of the product, such as a strip or a plate, leaving pickled from the finishing line, said information being delivered to a control module of the pickling system.
  • All the equipment making up the finishing lines are not shown in detail in the following figures in order to give clear and simple examples of various main types of finishing lines required on the market according to the invention. Only the main equipment therefore appears, because the person skilled in the art knows that it is necessary to combine ancillary equipment such as, for example, preparations of reel strip heads, strip drive pinch rollers, wringing, brushing, drying of belt, waste disposal systems, feed and exit trolley for coils and bundles of plates, etc.
