Definitions

  • the present invention concerns a method to manufacture a crystallizer with plates for the continuous casting of slabs, used in the steel industry to cast thin, medium and thick slabs with a rectangular section with the long side much bigger than the short side.
  • the plates of the crystallizer are provided with a plurality of channels through which a cooling liquid is made to pass.
  • the present invention also concerns the crystallizer obtained with said method.
  • Crystallizers with plates made of copper alloy for continuous casting are known, in particular for casting slabs, substantially comprising two wide walls facing each other to define, together with two narrow lateral walls, a pipe with a substantially rectangular section, through which the molten metal is continuously cast.
  • Each of the two wide walls comprises at least a plate, normally shaped on the internal face so as to define, in the central part and for a length which can occupy part or all the plate, a concave profile or recess.
  • This recess in the upper part delimits a zone in which, during use, an unloader is able to be positioned with the function of taking the molten metal inside the crystallizer.
  • the concave profile is normally made by chip-removal operations which, however, entail a series of disadvantages.
  • chip-removal operations are costly in terms of time and the equipment used, entailing obvious economic disadvantages. Moreover, it may sometimes be required to use different tools depending on the working step.
  • the final surface of the concave profile, obtained by chip- removal operations may have surface imperfections, in particular in the connection curves, which could influence the correct formation of the skin of the cast product, and cause possible breakages thereof, if the contact between the molten metal and the plate is not optimal during casting.
  • high working costs can be caused by the initial piece to be worked, which obviously is defined by bigger sizes of the machining allowance with respect to the final product to be obtained. In other words, the discard of noble material removed during working is also a considerable cost.
  • One purpose of the present invention is to perfect a method to manufacture a crystallizer with plates for the continuous casting of slabs that allows to obtain, simply and quickly, plates for the crystallizer that meet the dimensional and tolerance constraints required by the specifications, also to increase the working life of the crystallizer itself.
  • Another purpose of the present invention is to perfect a method to manufacture a crystallizer for the continuous casting of slabs that provides a reduced number of steps and that allows to reduce the times and costs of manufacturing the crystallizer.
  • Another purpose of the present invention is to manufacture a crystallizer for continuous casting that is economical and that has standardized and repeatable characteristics, even in the presence of particular shapes.
  • Another purpose of the present invention is to reduce the costs of manufacturing the crystallizer, reducing as much as possible the volume of copper or alloys thereof used to make it.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • a method according to the present invention which overcomes the limits of the state of the art and eliminates the defects present therein, is used to manufacture a crystallizer for the continuous casting of slabs comprising at least two wide walls, facing each other, each provided with at least one plate and defining the wide sides of the cast slab.
  • the crystallizer also comprises two narrow walls, interposed at the ends of the wide walls, which define the overall width of the cast slab.
  • the method comprises at least a first step of making at least one of the wide walls having, in its surface development, at least one shaped portion.
  • the method comprises at least the making of a molding apparatus provided with a mold and a counter- mold in which respective shaped surfaces are made.
  • the shaped surfaces together define, when the mold and the counter-mold are in the operating molding position, a molding cavity, which defines in negative the entire surface development, in shape and size, of the at least one plate of the wide walls.
  • the method also comprises the molding of the plate using the mold and the counter-mold, to obtain the at least one plate directly in the finished form, without relative movements between mold and counter-mold.
  • the shaped portion and the whole surface development of the at least one plate are obtained by deforming the latter plastically and rapidly obtaining the desired shaping.
  • the shaped surfaces of the mold and counter-mold faithfully reproduce the final shape of the plate to be obtained, it is possible to respect the design specifications and, in particular, the dimensional and geometrical tolerances, even very strict, at least of the shaped portion.
  • the shaped portion which during use will define the volume for the insertion of an unloader, is a critical zone of the whole crystallizer with regard to the phenomena of wear that can occur, and dimensional deviations of this part can considerably increase wear, reducing its working life.
  • the step of making the shaped portion is simplified, with the possibility of producing different profiles of shaped portions which, on the contrary, would be very complicated, long to make and costly, if chip-removal operations were used.
  • molding does not produce abrasions, scoring or other defects, and therefore the surface of the crystallizer that comes into contact with the molten metal does not need any further workings in order to be used.
  • two adjacent and overlapping plates are molded simultaneously in the molding apparatus, in order to form one of the wide walls, to define an internal surface and an external surface of the wide wall.
  • respective shaped surfaces are defined in the mold and the counter-mold, mating with the whole surface development of the internal surface and the external surface.
  • the method also comprises the coupling of the two plates to define together at least one of the wide walls.
  • the present invention also concerns a molding apparatus to make a crystallizer with plates for continuous casting, which comprises at least a mold and a counter-mold, each provided with respective shaped surfaces defining together, when the mold and the counter-mold are in the operating molding position, a molding cavity.
  • the molding cavity defines in negative the whole surface development, in shape and size, of at least one plate of the wide walls.

  • the first plate 14 and the second plate 15 are shaped in their central part, as is known, so as to define a concave portion 20, or shaped portion, able to allow the positioning of the unloader.
  • the concave portion 20 extends longitudinally for the whole height of the crystallizer 10 and has a longitudinal inclination that diminishes until it is canceled or, in some cases, until it is almost canceled, in correspondence with the exit section.
  • the part of the unloader positioned between the two wide walls 1 1 is substantially oval in shape, and is positioned at the center of the central cavity 13 and coaxially to the longitudinal axis Z.

More specifically, into the blind clamping holes 26 threaded bushings 37 are screwed, into which in turn the first screws 24 are screwed.
