Definitions

  • the present invention relates to a product securing system of the strip head type in a coating pot according to the preamble of claim 1.
  • an installation for coating a strip-type product moving in a so-called longitudinal direction (or plane) comprises a coating pot, comprising a coating agent such as a liquid metal (zinc or various alloys), in which plunges the strip in order to emerge generally vertical from said pot coated with said agent.
  • a coating agent such as a liquid metal (zinc or various alloys)
  • a handling bridge or lifting bridge of an area of submerged equipment (bottom roller, strip guide rollers, etc.) in the pot of coating makes it possible to ensure lifting of the said equipment as well as various elements of the aerial equipment type in the vicinity of the pot (wringing unit, strip stabilizer, etc.), including when the strip is engaged (uncut strip ) through this equipment or elements.
  • This type of lifting bridge generally has an offset lift that allows it to move to handle the equipment or elements along an axis of the pot without interfering with the belt present.
  • this handling can be carried out essentially when the strip at its entry or at its exit from the pot is cut so that an operator can access above the coating pot.
  • an operator uses a gripping pole to secure a strip head coming either from a cut strip at the pot outlet (for example to replace equipment or elements), or from a introduction of new strip head at pot entry.
  • the new strip head is secured to a chain or/and a stainless rope which dips into the pot and which the operator will pick up from the bottom of the pot using his gripping pole, then he will make use of a winch or other means of traction to pull said chain in order to extract the band head from the pot while passing it through the equipment or elements.
  • This very complex maneuver involves a significant risk of soiling of the equipment and elements in or in the vicinity of the pot and suffers from difficult and insecure access for the operator.
  • a set of sub-claims also present advantageous aspects of the invention.
  • Figure 1 presents a side view of an installation for coating a metal product of the strip head type (1, 1') comprising a securing system (4, 4', 6) according to the invention.
  • aerial type equipment at the exit of the strip from the pot such as a wringing unit, a strip stabilizer, etc. and arranged on either side of the outgoing strip faces in the vicinity of the pot as the first and second submerged equipment have not been represented on the figure 1 for reasons of clarity. They are however understood and at least interpretable as integral parts of said first and second equipment of any type (including submerged) in the following description, if it is not specified that they are aerial in the vicinity of the pot.
  • Said coating installation then comprises a stowage system (4, 4', 6) of product (1, 1') of the strip head type in a coating pot (2) filled with liquid metal of the installation of covering and comprising at least a first and a second equipment of the submerged type (e1, e2) in the pot and of the aerial type at the strip outlet of the pot, each of the said first and second equipment of the two types being respectively disposed on either side the other side of each of the faces of the strip running vertically in the pot and when it leaves the pot, said system comprising a means (3) for lifting one of said pieces of equipment (e1, e1') out of the pot, and being characterized by a holding means (4, 4') of the strip head at least above the pot.
  • a stowage system (4, 4', 6) of product (1, 1') of the strip head type in a coating pot (2) filled with liquid metal of the installation of covering and comprising at least a first and a second equipment of the submerged type (e1, e2) in the
  • figure 1 presents an example for which the first piece of equipment (e1) is extracted from the pot by the lifting means (3, 3a) to be moved to a position (e1') outside the field of the holding means (4, 4').
  • Said lifting means can be a lifting bridge (roller) usually used for handling equipment.
  • the first piece of equipment is then temporarily stored above the holding means or on the ground on a parking lot side of the coating installation.
  • the operator (op1) located near the zinc pot in the area (5) dedicated to operators can come and search the bottom of the pot using his gripping pole for the chain or rope of the new head strip (1') and bring it back onto said area (5).
  • the operator therefore avoids extracting the strip head from the pot while passing it through the first and second equipment, because access to the strip head is freed from any obstacle and therefore no longer takes place under an access difficult between submerged and aerial equipment and therefore unsafe for the operator.
  • This very complex maneuver is therefore avoided and also no longer carries a significant risk of soiling the equipment and other elements in or in the upper vicinity of the pot.
  • the operator can still guide said strip head over a brief path with his gripping pole towards a position (4' ) securing the holding means arranged above the zone (5) dedicated to the operators, at an easily accessible height for a man equipped with a gripping pole.
  • the securing system provides that the means for holding the head of the band comprises a device (6) for moving the head of the band (1') in at least one horizontal plane (axes X, Y) located above top of the pot (2).
  • the mooring line of the band head (1') can then be advantageously brought back without obstacle and without the labor of an operator towards a position (4) for securing the holding means located above the pot so as to approach the second equipment (e2). The operator is therefore here freed from any task that is difficult to access and at risk above the pot.
  • the lifting means is at least dedicated to lifting the closest equipment (e1, e1') to an operational zone (5) (accessible to an operator) and lateral to an upper periphery of the pot.
  • the device for moving the strip head imposes a bidirectional type movement in the plane (X, Y) located above the pot.
  • said plane is located at a height of 1m to 5m above the pot, so that it is easily accessible for a man equipped with a gripping pole.
  • the securing system allows an operator the two operations described in the form of the following operational methods.
  • the means for holding the head of the band comprises a simple arm which is movable towards a stop position located above the pot and aligned with the vertical plane of the band, so as to guarantee an arm position outside a vertical lifting plane of at least one of the two pieces of equipment by means of the lifting means .
  • figure 2 shows a top view of a first simple embodiment of the securing system according to the invention, in particular by providing an arm (9, 9') of the holding means (6, 4, 4') of the figure 1 in the form of a mobile stem, in particular here rotary.
  • Said arm is movable towards a stop position (9) located above the pot (2) and aligned with the vertical plane of the strip (1) in the running mode position, so as to guarantee an arm position off a vertical lifting plane of at least one of the two pieces of equipment (e1, e2 not shown, see figure 1 ) by means of the lifting means.
  • the arm here is of the rotary type in said plane (X, Y) located above the pot, the arm ideally having an elongated profile with an I or ⁇ section.
  • the pivot point (8) can simply be secured to a wall (7) or an existing or constructed column.
  • said arm can advantageously be provided with a translator carriage (10, 10') of the strip head thus movable on a part of said arm, the carriage ideally having a roller bearing around the elongated I-section profile or respectively in the elongated Q-section profile.
  • picture 3 shows a top view of a second simple embodiment of the securing system according to the invention, in particular by providing an arm (9, 9') of the holding means (6, 4, 4') of the figure 1 in the form of a mobile stem, here mono-directionally.
  • This mobile jib crane solution has the advantage of no longer, if necessary, having to provide a translation carriage as in the figure 2 .
  • the arm is parallel to a belt face and has a movable end (11) coupled to a longilineal guide (12) for movement of the arm between two planes defined by a scrolling mode position (1) and a strip removal position above the operational zone (5) (dedicated to the operators), the arm ideally having an elongated I-section profile or ⁇ .
  • the slender guide can simply be secured to a wall (7) or existing or constructed columns.
  • a drive of the mobile brackets, in particular in a retractable manner from the running zone of the band pot (2) at least towards the operational zone (5), according to figure 2 Or 3 , as well as the translation of the carriage according to figure 2 , can be simply manual or provided with a motorized aid depending on the efforts tolerated by an operator.
