Definitions

the present invention relates to a method of manufacturing, from a hollow ingot, a metal piece of generally tubular shape and large dimensions.
such a tubular piece has an outer diameter of about 3 to 5 meters, a thickness of about 100 to 300 millimeters, and a length of about 3 to 5 meters .
the hollow ingot is mounted in a forging press to undergo forging steps, in particular axial drawing, and working of the ingot thus stretched.
the work of the drawn ingot usually comprises between three and six coronation stages, making it possible to obtain a thick blank whose dimensions are substantially similar to those of the finished metal part. This blank is then machined to obtain the finished metal part.
the hollow ingot being mounted in the press during the entire manufacture of the blank, it is only after completion of the blank that the press can accommodate a new hollow ingot.
the production yield of the blanks is not optimal.
the invention aims in particular to overcome these disadvantages by providing a method of manufacturing a metal part whose dimensions are not limited by those of a forging press.
the subject of the invention is a manufacturing method of the aforementioned type, in which the work of the stretched ingot comprises the following steps:
the dimensioning of the blank is made by rolling on a circular rolling mill rather than in successive stages of coronation.
Such a circular rolling mill involves few dimensional constraints, which makes it possible to manufacture large metal parts, regardless of the dimensions of the forging press.
a rolling step is relatively quick to implement, such a step generally lasting ten minutes.
a rolling step is therefore faster to implement than several successive stages of coronation. This increases the production yield of metal parts, especially as a new hollow ingot can be mounted in the forging press while the previous ingot undergoes the rolling step.
a manufacturing method according to the invention may further comprise one or more of the following characteristics, taken alone or in combination.
the metal part is a shell of height between 2 and 6 meters, average diameter of at least 3 meters, and whose mass is less than or equal to 350 tons.
a known method of the prior art does not make it easy to make pieces of such dimensions.
the hollow ingot is supported in the forging press by a support mandrel inserted into the hollow ingot.
the method comprises a single step of boring the stretched ingot, this boring step being intended to increase by stretching the inner diameter of the intermediate preform sufficiently to allow the release of this intermediate preform of the mandrel.
This coronation stage is relatively fast, since it is only intended to allow the release of the intermediate preform.
the rolling step is carried out using a circular rolling mill, comprising at least one radial rolling mill comprising a driving cylinder, intended to cooperate with an outer surface of the intermediate preform, and a rotating mandrel, radially movable with respect to the intermediate preform intended to cooperate with an inner surface of the intermediate preform.
the rolling step is carried out using a circular rolling mill, comprising at least one axial mill comprising at least two motorized conical rollers, intended to cooperate respectively with the ends of the intermediate preform, at least one of the rollers. being axially movable.
the hollow ingot is made of a material selected from carbon steel, structural steel, stainless steel, and iron-nickel alloy.
the manufacturing process comprises, prior to the thirdornornage, a cutting step of the ends of the drawn ingot, and a step of cleaning the surfaces of this stretched ingot.
the manufacturing process comprises at least one step of heat treatment of the metal part, for example a quenching step, tempering and / or annealing of the metal part.
the metal part 10 is a shell of height between 2 and 6 meters, average diameter of at least 3 meters, and whose mass can reach up to 350 tons.
This example of course has no limiting character.
This ferrule 10 is made from a hollow metal ingot 10A of generally tubular shape extending longitudinally along an axis.
the hollow ingot 10A is for example made of carbon steel, structural steel or stainless steel.
the hollow ingot is made of carbon steel comprising up to 0.35% of carbon, of structural steel having less than 0.35% of carbon, up to 2.5% of an alloying element such as manganese, and up 12% of a sum of alloying elements such as nickel, chromium and molybdenum, in austenitic or ferritic stainless steel, or in an iron / nickel alloy comprising more than 40% nickel.
the hollow ingot 10A is mounted in a forging press 12, in which it is supported by a support mandrel 14 inserted into this hollow ingot 10A.
the hollow ingot 10A is subjected to a first step 100 of axial drawing by forging, to increase its length in the axial direction.
a stretched ingot 10B is obtained, which is then preferably subjected to a step 1 10 of cutting the ends of this stretched ingot 10B and cleaning its surfaces.
the drawn ingot 10B thus obtained is then subjected to a metal work intended to produce a blank 10D of generally tubular shape, having a shape and dimensions, in particular an inside diameter, a outside diameter, a thickness and a height, predetermined.
This work of the stretched ingot 10B comprises a step 1 of twinning of this stretched ingot 10B, made on the forging press 12, so as to form an intermediate preform 10C, generally tubular in shape, whose inner diameter is substantially smaller than the diameter predetermined interior of the blank 10D. It is the mandrel 14 itself which ensures the thirdornornage, since this operation takes place on the press forging 12.
a coronation stage is a forging step for increasing the diameters of a tubular piece by reducing its thickness.
This coronation step 120 is preferably unique and of short duration. Indeed, this coronation stage 120 is only intended to increase by stretching the inside diameter of the intermediate preform 10C, sufficiently to allow its clearance from the mandrel 14.
the intermediate preform 10C is then removed from the press 12, which can thus accommodate a new hollow ingot.
the manufacturing method then comprises a step 130 of rolling the intermediate preform 10C on a circular rolling mill 16, to form the blank 10D.
the circular rolling mill 16 comprises at least one radial mill 18 comprising at least one driving cylinder 20 intended to cooperate with an outer surface of the intermediate preform 10C, and a rotating mandrel 22, radially movable relative to the intermediate preform 10C , intended to cooperate with an inner surface of the intermediate preform.
the intermediate preform is laminated between the motor cylinder 20 and the rotary mandrel 22, which makes it possible to increase its diameter and to reduce its thickness until the inside diameter, the outside diameter and the predetermined thickness are obtained.
the circular rolling mill also comprises at least one axial rolling mill 24 comprising at least two motorized conical rollers 26, each designed to cooperate with one end of the intermediate preform 10C, in order to reduce the height of this intermediate preform to the predetermined height.
at least one of the rollers 26 is axially movable relative to the intermediate preform.
the tapered rollers are preferably movable radially relative to the intermediate preform, in order to follow the increase in its diameter.
the rolling mill 16 preferably comprises two lateral centering rollers 28 intended to ensure the proper positioning of the intermediate preform 10C during its rolling.
the method may comprise at least one final step of heat treatment of the metal part 10, for example a quenching, tempering and / or annealing step of this metal part 10.
the invention makes it possible to obtain metal parts 10 whose dimensions are not limited by those of the press 12.
a 25 to 45% increase in diameter can be observed between the forged intermediate preform 10C. and the rolled 10D blank.
the rolling step 130 makes it possible to obtain dimensions of the blank 10D, in particular a thickness, very close to the dimensions of the finished part 10, limiting the extent of the machining step 140.
the invention gives excellent results in terms of setting to the thousand (ratio between the mass of material necessary for the manufacture of the product and the mass of the product. final). Indeed, the invention allows a setting much lower than 3, or even less than 2.5.
the mass of material required to produce the part according to the invention is substantially equal to 86% of the mass of material required to produce the piece according to the conventional method, a reduction of 14% of material.
a hollow ingot conventionally used having a mass substantially equal to 200 tons the invention allows a reduction of 28 tons of the mass used.
the method according to the invention therefore allows a significant gain on the amount of material used.
the coronation step of the process of the invention is shorter than that of a conventional method. Indeed, in a conventional method, it is sought to obtain a wrought (that is to say a ratio between the starting section of the ingot to the section of the blank obtained) of 3, while in the process of l the invention seeks only to obtain an inner diameter of the blank which is slightly greater than the diameter of the rolling mandrel.
the conventional method generally requires several coronation stages, so that these stages last on average between 3 and 4 hours.
the rolling step 130 is carried out whose duration is less than one hour.
This duration of less than one hour is considered for an intermediate preform 10C with an initial inside diameter of 1800 mm, an initial outside diameter of 2172 mm, and for a rotation speed of the driving cylinder of 950 mm. mm / s, a diameter increase rate of 3mm / s, and a maximum rolling effort of 3300 tonnes.
the method of the invention allows improved productivity, the long press forging operations being reduced by the choice of the hollow ingot and the process steps which are optimized with the use of the rolling mill 16. therefore the production time of a piece.
use of the press is allowed to develop a new ingot while the previous ingot is rolled.
