Definitions

  • the present invention lies in the field of the manufacture of metal products, in general of flat and thin shape, such as steel strips or other metals, by shaping the product during passage between two cylinders of axes substantially which exert a compressive force on the product according to the preambles of claims 1 (method) and 7 (device) which are based on for example JP-A-61078537.
  • One of the major problems for obtaining a quality product is to know practically in permanently the air gap of the cylinders, to be able to act on thickness and convex regulations allowing to obtain a product of good geometric qualities, ie having a section of shape and dimension desired and constant over the length of the product.
  • air gap of cylinders we will designate thereafter not only the distance average separating the cylinders at the neck between these (narrowest passage, located in the plane common to the axes of the two cylinders), but also the form of passage to the collar, which is generally not exactly rectangular, either voluntarily, in the goal of obtaining a product with a slight bulge transverse, either due to the deformations of installation and cylinders.
  • the invention aims to solve these problems, and particularly aims to allow a determination fast air gap, continuously during the operation product shaping, so that it can act almost instantly on the regulating members of the position of the cylinders, or on the control devices other parameters of the formatting operation, for maintain a constant air gap of shape and dimensions required, for example on the means of control of the "domed" of the cylinder.
  • the profile is determined thermal of a generator distant from the neck, and finding in a situation where we measure variations position of at least three points of this generator, from a parameterized function defining the thermal deformation at a point of said generator depending on the axial position of this point and from of the said measurement of the variations of the position of the said at least three points, and we determine the profile thermal from the generator to the neck from said profile thermal generator away from the neck and said determination of variations in the length of the radius of the cylinder in the said planes, between the neck and the situation of the said generator distant from the neck.
  • the invention also relates to a device for shaping of thin metal products, such as bands, comprising two cylinders with substantially axis parallel defining between them a pass located in the common plane of their axes, support means provided bearings in which the ends turn axial of the shafts of said cylinders, and a chassis on which means for supporting at least one of the cylinders are guided and movable in translation in one direction bringing the cylinders closer or further apart.
  • this device is characterized in what it includes, for each cylinder, means of measuring the position of the generator diametrically opposite the neck, at three points respectively in a median plane perpendicular to the axes and in two secondary planes parallel to the median plane and located at proximity of the edges of the cylinders and the means of measurement, in said median plane, of the position of a generator located at 90 ° to the neck.
  • the device also includes means for measuring the position of the said generator located at 90 ° from the neck, in the said secondary plans.
  • said means are position sensors attached to the said means for supporting the cylinders and the device additionally includes means for measuring variations spacing of said bearings.
  • the so-called means for measuring the position of the generator diametrically opposite the neck are sensors attached to the chassis.
  • the continuous casting device shown in figure 1 comprises, in known manner, two cylinders 10, 11, of parallel axes and located in a horizontal plane P, internally cooled and rotated by drive not shown.
  • a cylinder is shown in simplified form in the drawing of the Figure 2 and includes a shaft 12, a body 31 linked to the shaft, and an outer ferrule 32, which constitutes the casting surface, held on the body by means known per se.
  • the surface outer 34 of ferrule 32 should be slightly "in This is why the longitudinal profile (in the direction of the cylinder axis) of this surface, obtained by machining, is concave. This concavity is by elsewhere determined cold so that subsists, warm and at the neck, the desired "hollow” counts held that the initial concavity tends to be reduced by the effect of thermal bulging during the heating of the ferrule.
  • the bearings 13F, 14F of the cylinder 10 are linked by support means, for example a fixed cross member 15F relative to the chassis 16 of the device.
  • 13M bearings, 14M of the other cylinder 11 are similarly connected by a cross member 15M guided on chassis 16, and movable on this, the position of the bearings 13M and 14M can be regulated by thrust cylinders 17, which provide also the reaction force opposing the effort spacing of the cylinders generated by the cast product.
  • the device also comprises means for measuring the position of the surface 34 of each cylinder.
  • These measuring means comprise, for each cylinder, a set 20 of sensors 22 intended to measure the position of the surface 34 on a generatrix of this surface located in the horizontal plane P, diametrically opposite the neck, and at several points along this generator.
  • three sensors 22 have thus been represented, one being located in a vertical median plane P 3 , and measuring the position of a point located substantially in the middle of said generator, the other two being located respectively in secondary vertical planes P 1 and P 5 , in the vicinity of the edges of the casting surface 34.
  • additional sensors can be used, placed in intermediate positions.
  • the set 20 of sensors 22 is fixed relative to to chassis 16.
  • These sensors are type sensors known in triangulation measurement applications, for example laser beam sensors, which can appreciate small variations in distance while being distant from the point whose position we want to determine.
  • These sensors 22 are arranged so as to target the surface of cylinder 11 through a window 18 fitted for this purpose in the cross member 15M of said support cylinder. In this way, the measurement made by these sensors is a direct measurement of the position of the points targeted from the surface of cylinder 11 relative to the chassis 16, and therefore independent of the position of the bearings 13M, 14M.
  • Means for measuring the position of the surface 34 also include a set 21 of sensors 23, located below cylinder 11 in a vertical plane passing substantially through the axis of the cylinder, this assembly being fixed relative to the bearings 13M, 14M, and is therefore moving with these.
  • the sensors 23 are by example of capacitive or inductive sensors, of measurement close together.
  • the assembly 21 includes three sensors 23, located respectively in the same vertical planes as the sensors 22 of the assembly 20, which therefore make it possible to measure at three points the position of the generator the surface 34 located at 90 ° from the neck, downstream from the latter with respect to the direction of rotation of the cylinder.
  • two sets 24, 25 of sensors are arranged near the second cylinder 10. It should be noted, however, that, given that the bearings 13F and 14F of this cylinder are fixed relative to the chassis 16, the sensors of the assembly 24 can then also be capacitive type sensors or inductive.
  • such sensors susceptible only take measurements at short distance, can also be used in place of sensors 22, to measure the position of the points of the generator opposite the neck on cylinder 11.
  • these sensors are fixed relative to the support means 15M of this cylinder, and additional sensors are provided for measuring the position of these support means relative to the chassis, for example sensors 26 arranged to measure gauge variations between the bearings of the two cylinders.
  • the ceding of the chassis 16 can also be considered negligible. However, using a arrangement of sensors such as that shown in Figures 3 and 4, we are completely free of this possible ceding since we measure the variations between the bearings of the cylinders, the ceding of the chassis then no longer having any influence on the measures.
  • C2 3 M is the value, measured by the sensor 23, of the variation in position of the point on the surface 34 of the shell of the movable cylinder 11, a point located 90 ° from the neck and in the median plane.
  • ⁇ 23 1 is the variation in length of the radius, in the secondary plane P 1 located in the vicinity of the edge of the ferrule, between the situation at 90 ° and the situation at 180 ° relative to the neck.
  • ⁇ 12 3 and ⁇ 12 1 and ⁇ 12 5 can be determined using a model, either according to the casting parameters, or by the difference in the value of the convex between 180 and 90 °, or by experimental curves or values.
  • the device and the process according to the invention make it possible to determine with precision and continuously the real air gap between cylinders during casting, defining it by its value in the center, its possible asymmetry by relation to the median plane, and the shape of the generator of each cylinder at the neck.
  • the sensor (s) located at 90 ° to the neck are particularly used to determine the influence of variations in radius and profile of cylinders due to thermal bulge effects, since in this situation 90 °, the deformations due to the mechanical effects of efforts to separate the cylinders are negligible. he would therefore also be possible to carry out the measurements above the cylinders at 90 ° upstream of the collar. However, for reasons of space, it is easier to place the sensors below the cylinders.
  • the shape of the profile of a generator of the cylinder was a curve defined by a mathematical function, the measurements carried out by the sensors located in the three planes P 1 , P 3 , P 5 making it possible to define the parameters of this curve and its position in the installation. It will be readily understood that, if there is a large number of sensors in planes parallel to P 3 , in addition to the planes P 1 and P 5 , that is to say distributed along the width of the table of the cylinder of surface 34, it will then be possible to know directly by measurement the position of several points of the profile and, therefore, to know precisely the profile of the cylinders, and therefore the air gap, without it being necessary to know the shape of the initial profile.
