Definitions

  • the present invention relates to a process for the manufacturing of spheroidal castings by using metal or permanent molds.
  • the resulting mechanical properties of the new parts are considered of great interest due to, among other things, the large number of graphite spheroids obtained in the parts.
  • spheroidal casting constitutes one of the materials that have been most widely used since its discovery in the 1950s. Compared to laminar or grey casting, the formation and subsequent growth of graphites in spheroidal form leads to significant increases in the break loads, the elastic limits, and, especially, in the elongations of the material. An adequate combination of these three mechanical properties entails the obtaining of materials with a wide range of technological applications.
  • This refractory material is characterized by a comparatively low thermal conductivity, which greatly limits the cooling rate of the cast alloy inside this type of molds.
  • the present invention relates to a new process for the manufacturing of spheroidal cast iron parts, which solves all the disadvantages mentioned above, when molds made up of mixtures containing silica sand (SiO 2 ) as the primary constituent are used. This is done by using metal or "permanent" molds.
  • This new type of mold has the following advantages:
  • This new technique can be used for the manufacturing of castings for the automotive industry, hydraulic components, metal molds for the glass industry, centrifuged tubes, etc.
  • the use of metal molds greatly accelerates the solidification rate and subsequent cooling of the material, causing major changes in the structures obtained in the as-cast state.
  • a first aspect of the present invention is a process for manufacturing spheroidal castings, which comprises the following steps:
  • the metal loads are selected from the group formed by high carbon ingots, foundry chip briquettes, pig iron, scrap metal, steel from the automotive sector, returns or any combination thereof.
  • the metal loads are selected from high-carbon ingots, returns, foundry chip briquettes, steel from the automotive industry or any combination thereof.
  • composition of the metal loads is:
  • the composition of the metal loads is:
  • composition of the loads is:
  • the process of fusion of the metal loads is performed in rotary kilns.
  • the melting and stay times of said metal load is 60 to 80 minutes (hours), preferably 70 minutes.
  • the step of adjusting the carbon and silicon contents are added depending on the content in the molten metal (metal loads) obtained in step a) in order to optimize the next step c) of spheroidization, such that the molten metal loads are transferred to at least 1 induction furnace (1000 Hz), preferably 3 induction furnaces.
  • the temperature of the base metal is maintained within a range between 1400 and 1500°C, preferably between 1400 and 1450°C.
  • the spheroidization treatment comprises the following steps:
  • the FeSiMg alloy comprises the following composition:
  • the FeSiMg alloy comprises the following composition:
  • the inoculant comprises the following composition:
  • the inoculant comprises the following composition:
  • stamped steel clippings are added until they cover the FeSiMg.
  • a casting step is performed in metal or "permanent" molds. Said step comprises the following sub-steps:
  • spheroidization is understood to mean a method for relieving the residual stresses in a high-carbon steel, consisting of heating for a long time at the lowest transformation temperature thereof, followed by slow cooling until it reaches room temperature.
  • the fusion process of the materials was carried out in rotary kilns with a capacity of 5500 kg.
  • the discharge of metal from the electric furnace is performed such that the metal falls on the
  • the slag was conveniently removed from the metal and the latter was quickly transferred to a ladle with a capacity of about 80 kg and equipped with an outlet siphon.
  • the purpose of this device is to prevent the introduction of the slag formed inside the molds during the casting.
  • the metal contained in the casting ladle was occasionally slagged off with this same aim.
  • the casting of the molds was performed manually through the siphon, ensuring that the casting cup was kept full throughout the entire process of filling the molds.
  • Table 2 Chemical compositions of the metal treated with Mg Element (%) C Si Mn P S Cu Cr 3.95-4.05 2.40-2.50 0.60-0.70 0.035-0.07 0.010-0.017 0.01-0.02 0.01-0.03
  • the silica sand molds were manufactured using a high-pressure vertical molding line (12 kp/cm 2 ) and mixtures composed of: 80.8% of re-used silica sand, 9.3% of activated sodium bentonite, 4.5% of carbonaceous material, 3.6% of water and 1.8% of new silica sand.
  • the mixtures were sent to the molding machine with a compactibility of 38-41 %.
  • the permanent molds were manufactured by machining a crude foundry product, cast into a mold previously prepared for this purpose.
  • the material used to prepare this crude product is flake graphite cast iron of the EN-GJL-200 grade.
  • the molds were coated internally with a layer of refractory paint and mounted on a carousel with a capacity for 12 molds, all equipped with an internal water refrigeration system.
  • a system of acetylene-fed burners was used to provide a layer of coal dust on the refractory paint that covers the internal face of the metal molds.
  • the addition of this carbonaceous layer may be regulated in each case.
  • the temperature of the molds was controlled manually.
  • the parts used to conduct this study are: a component of the brakes used in wind furnaces and a clamping jaw for railway tracks.
  • the weight of the brake caliper is 7.2 kg, showing sections between 5 and 43 mm. In the case of the jaw, the weight is 0.35 kg and sections vary between 5 and 12 mm. Thus, it is possible to evaluate the effect of different cooling rates in the same component.
  • Figure 1 shows the configuration of the half-molds designed to manufacture jaws for use in the railway sector.
  • the parts manufactured in both the permanent molds and in those manufactured with the silica sand mixtures correspond to the brake caliper.
  • the jaw was manufactured using only metal molds. After the manufacturing thereof, the parts were unmolded and, subsequently, shot blasted.
  • the materials of these parts were subjected to metallographic study in order to determine the spheroidization index (SI), the nodular density (N) and the composition of the metal matrix in different sections.
  • SI spheroidization index
  • N nodular density
  • the values of these parameters were obtained by analyzing 5 different observation fields in each sample and comparing them to standard patterns [15, 16].
  • the mechanical properties were determined on test-tubes machined directly on the parts. The dimensions of these test-tubes were dependent on the area of the part wherefrom they were obtained.
  • iron carbides Another structural phase detected, which reveals the behavior described above, is iron carbides. This type of compounds are formed only in the clamping jaws, i.e. in the narrower sections with more critical cooling kinetics. It is logical to verify that the highest concentration of carbides was observed in the peripheral areas pertaining to the narrower sections in this part. The more rapid cooling that occurred in these areas in contact with the metal mold favors the appearance of carbide phases. In these cases, effective control of the temperature of the molds and ensuring effective inoculation in the metal casting becomes even more relevant.
  • the surface defects that may be observed in certain parts and most often are: slag and wrinkles or folds.
  • surface wrinkles in spheroidal cast iron pieces it was observed that they are favored when using longer casting times and/or, primarily, the temperatures of the metal molds are higher.
  • Table 4 shows the values of the maximum load at breakage (B), the elastic limit (EL) and the elongation (E) obtained from the traction assays performed to determine the mechanical properties of the selected parts.
  • the mechanical assays were conducted only on the three parts subjected to the ferritization heat treatment described in Figure 2 .
  • the traction test-tubes were machined from two areas in each part. In the brake calipers, these areas correspond to the space designed for the hydraulic system (pot) and the central body (center).
  • the test-tubes were obtained from the support wedge and the support area of the part. Table 4.
