Definitions
- the present invention relates to improvements made to the chambers rapid cooling of strip heat treatment lines metallic.
- it intends to reduce the formation of folds that form on metal strips subjected to cooling in continuous heat treatment lines, in which said strips are brought through cooling zones provided with means for blowing a cooling gas.
- Figure 1 represents schematic, in perspective and partial cutaway of the cooling zone of a metal strip in a heat treatment line.
- strip 1 crosses the cooling zone fast 2 passing on an input roller 3 and an output roller 10.
- strip 1 is exposed to gas jets of cooling blown by a number of pairs of boxes such as 4 and 5 and 6 and 7, each provided with blowing means, each box being positioned on either side of the strip.
- Cooling boxes such that 4 and 5 and 6 and 7 have a limited length so as to allow the installation of one or more rollers or pairs of stabilizing rollers such as rollers 8 and 9, between two consecutive boxes such as 4 and 6 and 5 and 7, respectively, these well-known rollers being intended to guide and stabilize the band 1.
- the cooling gas is blown on the belt by all conventional means such as those described in particular in US -A-3,068,586.
- FIG. 1A On the graph illustrated by FIG. 1A, associated with FIG. 1, there is shown the intensity ⁇ of the cooling undergone by the strip 1 during its crossing of the zone 2.
- the intensity When entering between the first cooling boxes 4 and 5, the strip is suddenly exposed to a significant cooling flow, the intensity remains constant over the entire length of the cooling box, then this intensity decreases suddenly at the exit of said boxes.
- This variation of the cooling intensity undergone by the strip is renewed during of its passage between each subsequent pair of cooling boxes arranged over the entire length of zone 2 as can be clearly seen on the Figure 1A.
- the degree of cooling of the strip over the length of a box depends of the temperature of the blown cooling gas, characteristics geometry of the blowing holes of the boxes and the distance of these orifices relative to the strip.
- FIG. 2 of the accompanying drawings there is illustrated such a type of cycle cooling for which, for example, the strip is cooled according to slopes A-B, C-D and E-F, at least one of these slopes being greater than cooling slopes characteristic of the prior art.
- the sections B-C and D-E correspond to the discontinuities of the cooling due to interruptions in the supply air boxes for the in place stabilizing rollers such as rollers 8 and 9 shown on Figure 1.
- the current invention set itself the objective of solving this problem by providing a solution which limits the formation of folds in the strip during rapid cooling while maintaining the nominal belt speed in its crossing of the rapid cooling zone, that is to say, without loss of production.
- the cooling of the strip under the effect of the gas jets blown by the cooling chambers causes the web material to contract in directions parallel and perpendicular to the direction of travel Of the band.
- the contraction in the direction of travel of the strip is compensated by the belt traction control device with which the cooling zone or the line in which this cooling zone is integrated.
- the intensity of the strip cooling is constant and there is no difference significant between the compressive forces existing in a section of the strip and the one preceding it in the running direction of this strip.
- the forces of compression in a section of the band may be greater than those which exist in the section which precedes it and which undergoes a cooling of less intensity. This difference is all the more important as the variation cooling slope between these two sections is large, as is the case for example at the entry or exit of a pair of cooling.
- Figure 3 of the accompanying drawings shows the results of the modeling by calculating the thermomechanical stresses that appear in the material of the strip during the various stages of cooling of this strip operated according to the cycle illustrated in FIG. 2.
- This figure 3 illustrates the phenomenon described above and shows the evolution temperatures along the length L of the cooling zone as well as the resulting stresses in the material.
- Curve C1 shows the theoretical evolution of the strip during its crossing of the cooling zone
- curve C2 shows the actual evolution of this temperature with the singularities due to the discontinuity of the related cooling construction constraints of the cooling zone
- the curve C3 shows the evolution of the stress in the strip material over the length from the cooling zone.
- this stress peak depends on the temperature of the strip and of the variation in the cooling slope, i.e. the variation of cooling rate at point of curve C2 or the corresponding point as the strip enters or leaves the cooling zone corresponding to a pair of cooling boxes such as 4 and 5 on the figure 1.
- folds can take various forms, they can be continuous over the length of the strip or discontinuous, they can be parallel to the axis of the strip or meander across its width. They can be unique or develop according to the form of several continuous parallel folds, discontinuous, linear or according to a regular curve or not.
- the present invention provides a process which is essentially characterized in that it consists in gradually modifying the intensity of cooling each time variation of the slope of the cooling cycle, so as to limit the peak of corresponding stress in the material and reduce or eliminate the forces compression perpendicular to the tape running direction, which appear here between two consecutive sections of the strip in causing folds in the latter.
- FIG. 4A The method according to the invention is illustrated in FIG. 4A, associated with FIG. 4 which partially represents a rapid cooling zone 2 of the strip 1, according to a view similar to FIG. 1.
- FIG. 4A shows the modifications of the cooling efficiency of the strip obtained by the implementation of the process, at the inlet and outlet of the cooling chambers 4 and 5. It is obvious to a person skilled in the art that the process which is the subject of the present invention can be used anywhere in the cooling zone where produces a cooling slope variation in the strip cooling.
- the process which is the subject of the invention improves the quality of the finished product given that the heat treatment carried out on the material of the strip did not make it undergo a contraction likely to induce within it a constraint incompatible with its mechanical characteristics at temperature considered.
- the method according to the invention can be implemented by any means suitable for limiting sudden variations in slope of cooling or ensuring a gradual change of cooling between the input roller 3 and the first boxes 4 and 5, between two boxes consecutive, between the outlet boxes and the roller 10, or at any point the installation where a variation in the cooling slope occurs.
- FIGS. 5 to 10 various examples of non-limiting embodiment of means implementing the method according to the invention.
- FIGS. 5 to 10 schematically represent the start of an area cooling 2 with its first boxes 4 and 5 between which the strip 1 to be cooled is subjected to the action of blown cooling gas jets by the blowing means provided on the boxes.
- the boxes 4 and 5 are provided with conventional blowing means consisting of tubes or nozzles such that 11 arranged over the entire surface of the boxes facing the strip 1.
- the boxes 4 and 5 are provided with blowing means 11, the first of which, in the direction of travel of the strip, have a distance from the blowing orifice which is more important than those located on the current length boxes to reduce their efficiency.
- the distance between the blowing orifice and the strip can be gradually reduced to the current value over the entire length of the box so as to obtain progressive cooling of the conforming strip to the desired effect.
- the boxes of cooling 4 and 5 are provided with blowing means 11, the first of which in the direction of advancement of the strip are arranged with a step or a larger mesh than those located on the current length of the boxes so to obtain a progressive cooling of the strip.
- the progressiveness of the cooling efficiency of the strip can be obtained also by varying the supply pressure of the blowing orifices 11 of the boxes 4 and 5, located near a point of variation of the slope of cooling.
- this variation the supply pressure of the blowing orifices 11 is produced using a splitting of the blowing boxes 4 and 5 so that their part respective input is supplied independently by distributors 14 and 15 at a lower pressure than the supply pressure of the others respective parts of these boxes which are supplied by distributors 16 and 17.
- the modification of the supply pressure of the different blowing zones of the same box can be done, in a variable way, at by means outside the area, these means being controlled by the equipment control device and this at any point where the variation of the cooling intensity.
- FIG. 9 another embodiment of the invention is shown.
- deflectors such as 12 are provided, which are located on either side of the strip as well as on the lateral faces of the boxes 4 and 5, in the vicinity of the point where the slope of the cooling.
- These deflectors 12 force the cooling gas from the blowing holes 11 to run parallel to the strip (arrow 13), in a direction opposite to its movement.
- This channels the gas from cooling between the deflectors and the strip. Thanks to this arrangement the temperature of the cooling gas rises thus producing progressiveness cooling sought over the length of the deflectors 12.
- FIG. 10 another variant of the device has been represented according to the invention intended to limit the discontinuity of cooling between two pairs of consecutive boxes 4,5 and 6,7 between which are positioned stabilizing rollers 8 and 9.
- the blowing orifices 11 are installed on boxes 5 and 6 over the greatest possible distance so limit the length of strip not subject to cooling. Thanks to that arrangement, the desired cooling progressiveness is obtained.
- the means which, according to the invention, make it possible to modify gradually the intensity of the cooling of the strip with each variation of the cooling slope can be installed on each zone of the caissons where this variation in slope takes place so as to obtain the progressive cooling, at the inlet or outlet of the box or in all intermediate point of this box.
- the invention is not limited to the examples of realization described and / or represented but that it includes all the variants. This is how the present invention encompasses any device allowing to obtain a progressive cooling of the strip in all point of variation of its cooling slope.
