Definitions
- the invention relates to a product in the form of powder, for the protection of casting molds cast iron pipes manufactured by centrifugal casting; the casting molds used are commonly referred to as "shells".
- the coatings used for the protection of centrifugal casting shells of cast iron pipes were first made of inoculants and powdered refractory materials, as well as mixtures of silica and bentonite, put in place by projection of a suspension aqueous. Such coatings are described for example in the patent US 4,058,153 from Pont-à-Mousson.
- these products were replaced by powders sprayed dry on the shell before pouring cast iron, a technique referred to as the "dry spray". Whatever the technique used for their installation, these products are used to obtain on the one hand a thermal barrier effect limiting the rise in temperature of the shell and thus contributing to increasing its life, and secondly an inoculating effect on the cast iron so as to control the metallurgical structure of the pipe.
- inoculate more even if it means slowing the production rate to avoid the final heat treatment, or, on the contrary, to inoculate little, to increase productivity, and to heat-treat the cast iron part downstream.
- the supply inoculant of the "dry spray” can thus be positioned in rather wide limits, against the other effects asked to the product are the object of requirements more constant.
- the products used as "dry spray” are therefore generally composed of a mixture of several components, including an inoculant of greater or lesser effectiveness, which can constitute from 30 to 100% of the product, for example a ferro-silicon containing 0.1 to 3% of aluminum and calcium, and an inert mineral filler, for example silica or fluorspar, which can constitute from 0 to 70% of the product.
- an inoculant of greater or lesser effectiveness which can constitute from 30 to 100% of the product, for example a ferro-silicon containing 0.1 to 3% of aluminum and calcium
- an inert mineral filler for example silica or fluorspar
- the patent FR 2612097 (Foseco ) describes the use as a treatment agent of FeSiMg type alloys whose particles are electrically charged by friction.
- mixtures are in the form of powders of particle size always less than 400 microns, but free of fines.
- a particle size of between 50 and 200 ⁇ m is well suited.
- a method of manufacturing a cast iron brake element comprising a step of coating a mold with a nodularizing agent which comprises a ferrosilicon-based alloy which can be combined with a magnesium compound, the nodulating agent being intended to promote the production of ductile iron on the support surface.
- EP0930113A1 discloses an inoculant alloy based on ferro-silicon which may comprise, in addition to iron and silicon, the following metals: Mn, Zr, Ca, Ba, Sr and / or Al, in a casting process of casting in molds .
- the subject of the invention is a powder product for the protection of centrifugal casting molds of cast iron pipes, comprising a mixture of particles of an inoculating metal alloy, optionally inert mineral powders, and particles of a strongly reducing metal. and volatile to. the temperature of the liquid iron, said metal being selected from magnesium, calcium and magnesium and / or calcium alloys which contain less than 10% Fe.
- These products comprise an inoculant alloy, for example based on ferro-silicon, or a mixture of inoculant alloys, optionally a mineral filler, and a reducing agent, at a content of between 0.3 and 18%, consisting of volatile metal at the temperature of liquid iron, which is calcium, or magnesium, or an alloy containing at least one of these metals.
- Silicon alloys are particularly suitable, especially CaSi type alloys. It is thus possible advantageously to use alloys of composition (by weight): Si: 58-65%, Ca: 27-35%, Fe: 2-7%, Al: 0.4-2%.
- ferrous alloys typically containing more than 10% iron, of the FeSiCa type, often called CaSiFer and containing (by weight): Si: 51-58% Ca: 16-20% Fe: 23-27% Al: 0, 3-1, 5% as well as alloys of FeSiMg type containing (by weight): Si: 47-53% Fe: 35-48% Mg: 2-12% Al: 0.2-1.5%
- Ca: 0.1-1.5% rare earths: 0-2% give contrary disappointing results, clearly behind those obtained with the mixtures according to the invention.
- the reducing metals or alloys used are not used alone, but in the form of a premix with an inert substance, preferably calcium fluoride, magnesium fluoride or a mixture of these two fluorides.
- an inert substance preferably calcium fluoride, magnesium fluoride or a mixture of these two fluorides.
- the content of highly reducing metal or metal alloy in the premix is preferably between 15 and 60%.
- the particle size of the products is less than 400 ⁇ m, and preferably less than 250 ⁇ m. Fine particles smaller than 40 ⁇ m, and preferably less than 50 ⁇ m, are excluded to avoid dust emissions during use.
- a mixture according to the prior art was prepared from the following constituents: 85% of ferro-silicon at 75.2% Si, 1.3% Ca and 0.45% Al, at a particle size between 50 and 200 ⁇ m, and 15% of fluorspar of particle size between 10 and 150 microns.
- a mixture according to the invention was prepared from the following constituents: 55% of ferro-silicon with 75.2% of Si, 1.3% of Ca and 0.45% of Al with a particle size of between 50 and 200 ⁇ m, and 45% of a mixture consisting of 1/3 of fluorspar between 10 and 150 ⁇ m, and 2/3 calcium silicide at 60.1% Si, 31.7% Ca and 4.3% Fe.
- a mixture according to the invention consisting of 3% of the above mixture and 97% of ferro-silicon with 75.2% Si, 1.3% Ca and 0.45% Al of particle size between 50 and 200 ⁇ m.
- this product gave results judged to be better than those obtained in Examples No. 1 and No. 2; the pipes were demolded after 37 seconds of cooling and on the pipes thus manufactured, a thickness of ferritic cast iron of 30 ⁇ m was noted. The surface condition of the pieces was considered excellent.
- this product gave results in a net shrinkage compared to those obtained in Example 3; the pipes were demolded after 50 seconds of cooling and, on the pipes thus manufactured, there was a thickness of ferritic cast iron of 35 ⁇ m, and the appearance, on the surface of the pieces, of pits quite unacceptable, of a density of about 25 per m 2 .
