Definitions
- the present invention relates to an additive in the form of cored wire for the treatment of liquid steel baths to obtain steels with a high content of lead.
- Lead is well known for improving the machinability of steels because, insoluble in steel, it forms exogenous inclusions of lead (nodules) which act as a lubricant and promote the division of chips during the machining of rolled steels.
- lead nodules
- it has significant disadvantages of use, given its toxicity, its high density (higher than that of liquid steel) and its low melting point. It is introduced into liquid steel baths by injection of balls or shots through a submerged lance or in the form of cored wire, the latter technique being known to be generally more flexible and more reliable.
- EP 0 316 921 discloses a lead-containing additive for steel baths, in the form of a cored wire composed of a metallic sheath and a finely divided filling material, the latter containing metallic lead and / or lead alloys and a material containing lime and releasing carbon dioxide (CO 2 ) at the temperature of the liquid steel bath.
- the present invention aims to overcome these disadvantages by proposing a new additive comprising a lead and / or lead alloy powder whose size and particle size distribution are very specific, said powder being associated with a compound capable of ensure a homogeneous distribution of lead in the liquid steel bath.
- the invention relates, according to a first aspect, to an additive comprising metallic lead and / or lead alloy (s) intended to treat liquid steel baths, said additive being in the form of compound flux-cored wire.
- a metallic sheath and a finely divided filling material consisting of a metallic lead powder and / or lead alloy and a powder of a compound capable of releasing a gas, inert with respect to the liquid steel, at the temperature of the liquid steel bath, said additive being characterized in that said metallic lead powder and / or lead alloy powder consists of a particle size fraction G R of between 200 ⁇ m and 500 ⁇ m and in that said particle size fraction G R has the following characteristics:
- the invention relates to a process for treating liquid steel baths with an additive comprising metallic lead and / or lead alloy (s), comprising a step of adding to said baths of an additive in the form of a cored wire composed of a metallic sheath and a finely divided filling material, the latter consisting of a metallic lead powder and / or lead alloy and a powder of a gas-releasable compound, inert with respect to the liquid steel, at the temperature of the liquid steel bath, said metallic lead powder and / or lead alloy powder consisting of a G R size fraction which is between 200 ⁇ m and 500 ⁇ m and which has the following characteristics: a sieve of 200 ⁇ m: G R ⁇ 5%;
- the subject of the invention is the use of the additive comprising metallic lead and / or one or more lead alloys, described above, for treating liquid steel baths.
- the invention also relates, according to a fourth aspect, to a rolled product made of steel with a high lead content obtained by the aforementioned process, characterized in that the lead nodules are less than 100 ⁇ m in size and, for the most part, up to at least 80%, distributed in the rolled steel according to a type of random distribution as shown in Figure 3a. This distribution gives the rolled steel optimum machinability characteristics.
- FIG. 1 represents the characteristics of sizes and particle size distributions of the granulometric fraction G R ;
- FIG. 2 shows the variation of the lead yield as a function of the amount of additive added to the steel bath expressed as the length of flux-cored wire added per tonne of liquid steel;
- Figure 3 shows schematically the different types of distribution of lead nodules in the final product of solid steel;
- the present invention relates to a novel additive comprising metallic lead and / or lead alloy (s) intended for the treatment of liquid steel baths with a view to obtaining steels with a high lead content.
- this additive is in the form of cored wire composed of a metal sheath and a finely divided filling material, the latter consisting of a metallic lead powder and / or lead alloy and a powder of a compound capable of releasing a gas, inert with respect to the liquid steel, at the temperature of the liquid steel bath.
- said metallic lead powder and / or lead alloy powder consists of a particle size fraction G R of between 200 ⁇ m and 500 ⁇ m.
- This granulometric fraction is preferably in the form of small granules or very fine beads.
- said granulometric fraction G R has the following characteristics:
- This particle size distribution (contained in the area shown in Figure 1) gives the cored wire optimal filling properties leading to a high performance metallurgical treatment of liquid steel baths.
- the choice of such a particle size distribution ensures a level of residual porosity much lower than those observed in cored wires made from a conventional lead powder.
- the porosity is thus between 5% and 20% maximum while for a conventional yarn, the value is generally between 15 and 40%.
- the metallic sheath surrounding the additive is formed of a material capable of dissolving in the steel bath with a speed sufficiently high to allow the release of said additive and without introducing unwanted components therein.
- the metal sheath is unalloyed mild steel. Its thickness is between 0.1 and 1 mm, preferably between 0.2 and 0.6 mm.
- the diameter of the cored wire according to the invention is between 5 and 20 mm, preferably between 9 and 15 mm.
- the additive according to the invention is in the form of cored wire containing from 100 to 1000 g of lead per meter of wire.
- the compound powder able to spontaneously release a gas, inert with respect to the liquid steel, at the temperature of the liquid steel bath (between about 1550 and 1650 ° C.), this is also present in finely divided form, with a particle size of less than 1 mm, preferably less than 0.5 mm.
- the release of the gas bubbles in the liquid steel bath creates an updraft which leads to a very random distribution of the lead inclusions formed from the particle size fraction according to the invention, thereby standardizing their distribution in the dye bath. liquid steel.
- the compound capable of spontaneously liberating a gas, inert with respect to the liquid steel is a mineral compound such as limestone (calcium carbonate) or uncured dolomite, and said inert gas by compared to liquid steel is carbon dioxide.
- the inorganic compound is used in an amount of 3 to 30% by weight relative to the weight of the lead metal and / or lead alloy or alloys used (s).
- the invention relates to a process for treating liquid steel baths with an additive comprising metallic lead and / or lead alloy (s), comprising a step of adding to said baths an additive in the form of the cored wire described above.
- a cored wire containing such a powder makes it possible to obtain a lead yield in the liquid steel higher than that obtained with a conventional wire or with that described in the document EP 0 316 921.
- Figure 2 shows industrial results for lead yield versus quantities added (the variation in lead yield versus the amount of additive added to the steel bath expressed as fluxed wire length per tonne of steel) .
- the lead yield is defined by the following equation:
- - C F is the final lead content obtained in the liquid steel ladle
- - C A is the target lead content in the liquid steel ladle
- Yp b is the yield of the addition of lead.
- the cored wire containing the lead powder and / or a lead alloy whose particle size respects the specificities described in this invention makes it possible to obtain a higher lead yield than with a conventional powder. It also makes it possible to obtain very regular and constant yields regardless of the length of yarn injected into the liquid steel bath. Thus, the smaller dispersion makes it possible to very substantially increase the chances of success in obtaining the lead shot in the final steel.
- the addition of the additive according to the invention in the liquid steel ladle takes place before the casting.
- an amount of from 0.1 to 10 kg of additive in the form of cored wire per ton of liquid steel to be treated is introduced.
- the cored wire is discharged into the steel bath at a speed of 50 to 200 m / min, preferably 100 to 150 m / min.
- Example 1 illustrates the high values of lead yield obtained through the use of the new additive according to the invention.
- Thread length injected 334 m
- Thread injection speed 150 m / min
- Liquid steel weight in pocket 115 t
- the yield of the addition of lead in cored wire obtained is: 72.0%.
- the particle size of the lead particles contained in the flux-cored wire has been chosen within a very small range of 200 to 500 ⁇ m, the lead inclusions, insoluble in the liquid steel, are distributed evenly throughout the pocket.
- the reduced size of the lead inclusions makes it possible to greatly reduce their sedimentation in the bottom of the pocket.
- the solidified product is therefore more homogeneous in lead content irrespective of the quantity of liquid steel remaining to flow. This is illustrated in the following example.
- loom refers to a solidified steel unit (round, rectangular, or polygonal steel ingot).
- the use of the cored wire containing a finely divided lead powder according to the invention makes it possible to reduce the washing operations of the bags used for the preparation of liquid steels with a high lead content.
- Pocket refractories are less polluted by heavy lead infiltration.
- the steelmaker notes fewer lead residues in the opening / closing systems of the taphole as well as in the joints between the refractory bricks.
- the scrap rate of rolled products (bars) of high lead steels is greatly reduced by the use of the additive containing a lead powder and / or lead alloy whose particle size is described herein. invention.
- the bars are discarded if the size and distribution of the lead nodules do not meet the specifications imposed by the client of the steelmaker.
- 100% of the bars are compliant whereas the use of a cored wire containing a conventional lead powder can cause up to 30% rebus.
- the lead nodules are more suitably distributed in the rolled product thus promoting the machinability properties.
- the Applicant has specifically developed a criterion for qualifying the distribution of the population of lead nodules in rolled products. It has therefore defined distribution indices and the associated criteria and finally the conditions for experimental measurements.
- IR distribution index D: diagonal of the analysis zone d,: minimum distance between lead nodules (nearest neighbors - Fig. 4)
- NI number of lead nodules with a minimal distance associated.
- the lead nodules are distributed randomly (thus favoring machinability) when I R is greater than 1.4%.
- This index I R is relevant only if a large number of lead nodules are taken into account. This number has been fixed at 500. A specific method of analysis has thus been developed.
- the characterization of the lead nodules is carried out on the surface of a sample taken at mid-radius from a rolled steel bar with a larger diameter at 40 mm, and observed in the rolling direction.
- the surface of the sample taken is polished to 1 ⁇ m sheet.
- Lead nodules are identified and characterized by observation of the sample surface with a scanning electron microscope equipped with a backscattered electron detector (SEM-FEG) coupled to an image analyzer. With this mode of observation and thanks to the chemical contrast, lead nodules appear with a significantly higher average gray level than the steel matrix and inclusions of other types (such as sulphides, oxides, nitrides). .) which makes it possible to distinguish them and isolate them easily.
- the measurement method consists in observing an area of at least 25 mm 2 , in a square-shaped area centered at mid-radius of the bar. All lead nodules with a small ferret diameter greater than 2 microns are taken into account and measured. More than 500 lead nodules must be taken into account. For each of these nodules, the position parameters (X and Y coordinates in the reference of the zone examined) and the main morphological parameters (surface of the nodule, diameter of Feret ...) are saved in a file of results.
- the distribution parameters are then calculated to highlight the distribution of lead nodules to optimize the machinability properties of the product.
- Several types of distributions represented in the appended FIG. 3, are taken into account: random (FIG 3a), in clusters (FIG 3b), in bands (FIG 3c) or in network (FIG 3d).
- random in clusters
- FIG. 3c in bands
- FIG. 3d in network
- the proportion of nodules distributed according to the random type should be maximum. and preferably at least 80%.
- the use of the novel additive comprising metallic lead and / or a lead alloy, according to the invention, for treating the liquid steel bags with a view to obtaining steels with a high lead content has many advantages and leads in particular to to: improving the efficiency of the addition of lead in the liquid steel bath; the improvement of the conditions of elaboration and treatment of steels with a high lead content: indeed, the increase in the addition yield makes it possible to reduce the emission of harmful fumes and thus an improvement of the health and safety conditions for steelworks personnel; a strong improvement in the distribution and fineness of the lead inclusions in the liquid steel which makes it possible to keep the lead content of the steel constant from the beginning of the casting until the complete emptying of the pocket; a strong decrease in the sedimentation of lead in the bottom of the pocket and thus a virtual disappearance of the lead residues in the opening / closing systems of the tapholes as well as in the joints of the refractory bricks; the improvement of the final machinability properties of rolled steel products thanks to a better distribution of lead nodules in
