Definitions
- the present invention relates to a process and apparatus for the manufacturing of long products in a continuous casting plant.
- long products relates herein to blooms, billets or generally to all products in their physical form in which they exit from the mould of a continuous casting machine fed by a steelworks furnace, such as an arc furnace (EAF) or the like.
- EAF arc furnace
- a first drawback of this solution relates to the fact that in order to effect the passage from an auxiliary line to the main line, appropriate transversal transfer systems must be set up.
- control of the transfer rates of the rough products in the feeding (different for the main line and the auxiliary line) must be particularly precise in order to allow the regular continuous feeding of the mill.
- the product P leaves the ingot mould vertically and is then deformed along a section of circumference until it acquires a horizontal position and straight trajectory, in order to limit the vertical encumbrances of the plant.
- the trajectory followed by the product P comprises a first portion, immediately downstream of the mould section, which develops according to a circular section with an opening of about 90° (from vertical to horizontal) and a second portion which develops horizontally: the joining section of the two trajectories (curved and straight line) is indicated with the term "transition area”.
- the W.S.U. (Withdrawal Straightening Unit) is typically positioned in correspondence with this area, which straightens the product P from a curved form to a straight form and allows the withdrawal speed to be controlled.
- the W.S.U. obviously acts with its rolls in the sections of trajectory situated immediately upstream and downstream of the transition area.
- figure 1 shows the terminal part of the mould L of a continuous casting from which a product P exits.
- the plant must be modified and dimensioned so that the "metallurgical length" of the product P is totally included within the curved section (from the ingot mould to the W.S.U. rolls), i.e. upstream of the transition area, shown in fig.1 with the reference ZT.
- Metallurgical length indicates the portion of product P in which there is a central nucleus, not yet completely solidified (solid grains in suspension coexist in the nucleus, in a liquid matrix).
- the W.S.U. is not a traditional unit, but is specifically produced so that it acts only on the straight portion, downstream of the transition area ZT: this special W.S.U. in fact comprises a series of rolls, all positioned downstream of the transition area ZT and having rotational axes parallel to each other and substantially positioned at the same distance from the product P.
- the product P immediately downstream of the mould, passes through the rolling stands R, which are structured so as to generate a deformation of the product which creates a sectional variation obtained by maintaining the perimeter of the product P constant.
- This deformation is often defined in the technical field as "soft core reduction” and has the primary objective of improving the quality of the finished product.
- sectional variation of the product P could obviously be useful for increasing the advance speed of the product.
- the plant set-up is extremely expensive, as the rolling stands R must be produced with "nipper" shells suitable for being opened and closed to allow the passage of the so-called "head of the dummy bar" in the initial start-up phase of the plant, which has a fixed section, equal to that of the outlet mouth of the mould.
- the rolling stands R In order to allow the passage of the head of the dummy bar, the rolling stands R must not have a conical passage section, otherwise the head (with a fixed dimension) would not be able to pass.
- JPH03198964A discloses a casting exits' path over a metallurgical line (wherein the hot product comprises a liquid core) comprising as reducing means two pairs of rolls with vertical axis and only one pair of rolls with an horizontal axis and located between said rolls. At the last pair or rolls, the hot product with liquid core will only be compressed by reducing in a one-directional direction and may be also "freely" enlarged in the other perpendicular direction (e.g. from a square to a rectangular section wherein the product's height is reduced but the transversal length is free to increase). Such a deformation does not allow a robust reduction in both perimeter and section and consequently cannot provide a significant acceleration of product if any.
- an objective of the present invention is to solve the above-mentioned drawbacks by providing a process and apparatus for the manufacturing of products in a continuous casting plant in which it is possible to obtain an acceleration of the product downstream of the ingot mould so that the advance rate of the product can be increased from the initial casting rate to the feeding rate of the mills, without having to apply costly modifications to the known plants and maintaining relatively limited encumbrances.
- a process for the manufacturing of a long metallic product in a continuous casting plant wherein said product follows a trajectory comprising a curvilinear section and a straight section.
- the process comprises at least a first and a second deformation phase, each of said phases comprising a contemporaneous deformation of the perimeter and of the transversal section of said product, the first deformation phase being effected in said curvilinear section and the second deformation phase being effected in said straight section, the first and the second deformation phase being effected in an area where liquid metal is still present in the product and at a location where each deformation provokes an increase in the speed of the product.
- the process according to the invention may also comprise the following steps:
- the process according to the invention may also comprise the following steps:
- the process according to the invention may also comprise the following steps:
- the reduction of said section in said first or said second direction which is obtained as a whole between the section upstream of the first deformation and that downstream of a last deformation ranges from 14% to 16.8%, and is preferably equal to 15.4% of the initial dimension.
- advance speed of said product downstream of said ingot mould is equal to about 5 m/min.
- said deformations are created in a withdrawal/straightening unit of said product.
- the invention also relates to an apparatus for manufacturing a metallic long product which effects the above mentioned process.
- the apparatus may comprise:
- the distances between two consecutive rolls of two consecutive pairs decrease to create a deformation of a long metallic product poured from a mould, in particular a reduction of the section in one direction, preferably a vertical direction.
- the withdrawal/straightening unit may comprises alternating pairs of rolls having perpendicular rotation axes between rolls of adjacent pairs, in particular alternating horizontal and vertical axes, wherein the distances between two rolls of each pair decrease to create a deformation of a long metallic product poured from a mould, in particular a reduction of the section on two directions, preferably a vertical direction and a horizontal direction.
- the Applicant has observed that the above mentioned objective can be achieved by reducing the section and perimeter of the product, by acting in both the area prior to and subsequent to the transition area from the curved form to the linear form of the product, said reductions in the section and perimeter being effected under conditions of the product having a nucleus not completely solidified and at a location where the product can be significantly accelerated.
- section and perimeter are modified in the development of the metallurgical length, which extends beyond the transition area of the product from curvilinear to rectilinear.
- this shows a scheme relating to the process and apparatus according to a first embodiment from the prior art.
- the process for manufacturing an elongated metal product 1 in a continuous casting plant envisages that the product 1 follow a trajectory comprising a curvilinear section and a straight section and that it comprises at least a first and a second deformation phase, each of said phases including a contemporaneous deformation of the perimeter and transversal section of said product 1.
- the first and second phase are respectively effected, one in the curvilinear section and the other in the straight section.
- the first and second deformation phases respectively define two extremities of a deformation line indicated by LD and located on a barycentric axis of the product 1.
- This deformation line LD is included within a metallurgical line (also called metallurgical length) LM measured on the same barycentric axis of said product 1 and delimitated by a first extreme point in which overheated liquid metal is present in the product 1, and a second extreme point in which said product 1 is completely solidified; this aspect will be dealt with further on.
- a metallurgical line also called metallurgical length
- the process envisages the deformation of the section and perimeter of the product, by acting in a single direction, preferably a vertical direction.
- a more developed variant of the process and relative apparatus envisages that the deformation be effected by acting in two perpendicular directions, horizontal and vertical.
- reference 1 indicates the elongated product which vertically leaves the ingot mould 2
- reference 10 indicates the apparatus as a whole.
- the product 1 is preferably steel in the form of a billet or bloom or similar sections.
- the product 1 Downstream of the ingot mould 2, the product 1 is guided by guiding rolls 3 (dotted line) as far as the straightening/withdrawal unit (W.S.U.) indicated as a whole by reference 4.
- the W.S.U. includes at least three pairs of rolls 4A, 4B, 4C, situated, with reference to the transition area ZT (point or region in which the product 1 passes from a curved to a flat configuration) upstream (rolls 4A) of the area ZT, in correspondence with the area ZT (rolls 4B) and downstream of the area ZT (rolls 4C).
- the rolls 4A, 4B and 4C all have a horizontal axis and at least one roll, preferably one for each pair, is motorized.
- the distance between the first pair of rolls 4A and the second pair of rolls 4B is greater than the distance between the second pair of rolls 4B and the third pair of rolls 4C, thus creating a deformation of the product 1, in particular a reduction in the section in one direction, in particular vertical.
- the decrease in the vertical dimension which is obtained as a whole between the section upstream of the first pair of rolls 4A and downstream of the third pair of rolls 4C ranges from 14% to 16.8%, preferably equal to 15.4%.
- the speed downstream of the third pair of rolls 4C is increased by a value equal to about 18.7%.
- the speed downstream of the third pair of rolls 4C is equal to about 6 m/min, and therefore optimum for sending the product 1 directly to a mill L.
- the product 1 can be preheated in an induction furnace or similar.
- the semi-solid core 11 of the product 1 extends in the deformation area between the first 4A and third 4C pair of rolls.
- the product 1 In the very first area downstream of the mould 2, the product 1 has a relatively reduced “skin thickness” (i.e. a thickness of the solid perimetric wall 12).
- the central nucleus, or core 11, of the product extends significantly in this area and approximately occupies a surface higher than 80% of the transversal section of the product 1.
- the temperature of the nucleus 11 is obviously higher than that of the perimetric wall 12, so that both the liquid phase and metal grains already solidified coexist in said nucleus 11.
- the skin thickness 12 tends to increase and the section of the nucleus 11 to progressively decrease.
- the "metallurgical line” LM (referring to the length of the portion of product 1 measured on the barycentric axis of the product 1 and in which there is a central nucleus not yet completely solidified, in which solid grains and not overheated liquid metal co-exist, LM being measured from the exit of the mould 2), to extend beyond the last pair of rolls 4C of the W.S.U. machine 4.
- the deformation line LD must therefore be included within the metallurgical length LM.
- the product 1 must reach the transition area ZT still provided with a semi-liquid core which continues to be present at least as far as the last roll 4C of the W.S.U. 4, as schematically illustrated in figure 4 enclosed.
- the rolls, and in particular the first pair of rolls 4A are located at a position where the solidified skin thickness 12 is important enough so that the deformation realized by the rolls also provokes an increase of the speed of the product in the advancing direction of the product. In other words the rolls should not be located too close to the mould 2 where the product is still too liquid and where the deformation would not provoke sufficient acceleration of the product.
- FIG. 3 A further variant is shown in figure 3 , in which the same parts are indicated with the same reference numbers and consequently no further reference will be made thereto.
- the apparatus differs from the apparatus previously described in that the W.S.U. 45 comprises both the pairs of rolls 4A,4B,4C described above and also a plurality (for example three) of pairs of rolls 5A,5B,5C having a rotation axis perpendicular to that of the pairs of rolls 4A,4B,4C.
- the pairs 4A, 4B, 4C for example, have a horizontal axis, whereas the pairs 5A, 5B, 5C have a vertical axis.
- the W.S.U. machine 45 in this case comprises both series of rolls, the pairs with a horizontal axis 4A, 4B, 4C, and also those with a vertical axis 5A, 5B, 5C alternating, so that a pair of rolls with a horizontal axis is followed by a pair with a vertical axis and vice versa.
- the first pair of rolls 4A of the W.S.U. machine 45 which the product 1 encounters when leaving the mould 2 is preferably a pair of rolls with a horizontal axis.
- the pairs of rolls 4A,4B,4C,5A,5B,5C are arranged and dimensioned so as to generate a deformation of the product 1 in two directions perpendicular to each other, preferably horizontal and vertical.
- the arrangement of the pairs of rolls 4A,4B,4C,5A,5B,5C is such that a deformation in a vertical direction is followed by a deformation in a horizontal direction and vice versa.
- the "metallurgical line" LM can extend beyond the last pair of rolls 5C of the W.S.U. machine 45 and the deformation length LD is included within the metallurgical line LM.
- the process comprises the following steps:
- a further advantage obtained with the present invention is that the W.S.U. machine 4 can be a machine, in which there is the expedient of positioning the pairs of rolls 4A,4B,4C at suitable distances in order to effect the method described above.
- a W.S.U. machine can be modified by adding two, three or more pairs of rolls 5A,5B,5C with a horizontal axis to cause a reduction in the section of the product 1 in more than one direction.
