Definitions

  • the present disclosure relates to a mould flux and to a method of manufacturing a nickel-base alloy.
  • KR2019009901 relates to a flux to be employed by casting of steels, said flux comprising SiO 2 37.6-39.6 wt%, CaO 27.2-29.2 wt %, MgO 2.6-3.6 wt%, Al 2 O 3 1-3 wt %, Na 2 O 15.1-16.1 wt%, K 2 O 0.16-0.18 wt%, Fe 2 O 3 0.56-0.83 wt%, Li 2 O 2.57-2.85 wt%.
  • the present disclosure therefore provides a mould flux having a composition of, in weight% SiO 2 15-25; CaO 15-35; Al 2 O 3 1-7; Na 2 O 18-30; K 2 O 15-25; Fe 2 O 3 0-5; C 0-4; TiO 2 0-2; MnO 0-2; MgO 0-2; Li 2 O 0-10; and wherein the melting point of the mould flux is less than or equal to 1300°C.
  • Mould fluxes are synthetic slags constituted by a complex mix of oxides, minerals and carbonaceous materials.
  • the main oxides are silica (SiO 2 ), calcium oxide (CaO), sodium oxide (Na 2 O), alumina (Al 2 O 3 ) and magnesium oxide (MgO).
  • the liquid slag formed by the flux constitutes a barrier to avoid steel re-oxidation by contact with air and the entrapment of other gases, such as nitrogen.
  • the fluxes can be added through the top of the mould on the liquid steel, manually or automatically.
  • the mould flux is provided as a powder having the above-mentioned or below-mentioned composition. The flux will then melt in contact with the molten alloy.
  • the present composition limits the CaO content in the mould powder compared to conventional mould fluxes.
  • Perovskite phase formation is assumed to be as follows: SiO 2 +Ti ⁇ TiO 2 +Si.
  • TiO 2 may together with CaO form Perovskite as a solution of Ca 2 Ti 2 O 5 and Ca 2 Ti 2 O 6 .
  • CaO in the flux contributes to the formation of Perovskite.
  • the mould flux according to the present disclosure suppresses the formation of a Perovskite phase compared to mould fluxes of prior art.
  • At least a part of Na 2 O, SiO 2 and Al 2 O 3 present in the mould flux are in the form of Sodium Feldspar (Na 0.33 Al 0.35 Si 1.13 O 2.95 ).
  • at least 25%, or at least 40% of Na 2 O, SiO 2 and Al 2 O 3 present in the mould flux are in the form of Sodium Feldspar (Na 0.33 Al 0.35 Si 1.13 O 2.95 ).
  • at least 50%, or at least 90% of the Na 2 O present in the mould flux is in the form of Sodium Feldspar, (Na 0.33 Al 0.35 Si 1.13 O 2.95 ).
  • At least a part of K 2 O, SiO 2 and Al 2 O 3 present in the mould flux is present in the form of Potassium Feldspar (K 0.33 Al 0.35 Si 1.13 O 2.95 ).
  • at least 25%, or at least 40% of K 2 O, SiO 2 and Al 2 O 3 present in the mould flux is present in the form of Potassium Feldspar (K 0.33 Al 0.35 Si 1.13 O 2.95 ).
  • at least 50%, or at least 90%, of the K 2 O present in the mould flux is present in the form of Potassium Feldspar (K 0.33 Al 0.35 Si 1.13 O 2.95 ).
  • the content of Na 2 O in the mould flux is 18-25 weight%.
  • the content of K 2 O in the mould flux is 15-22 weight%.
  • the content of TiO 2 in the mould flux is >0.05 weight%.
  • the content of Li 2 O in the mould flux is >1.0 weight%.
  • the ratio of CaO and SiO 2 (CaO/SiO 2 )- is in the range of 3:4 to 4:3, such as 1:1. These oxides are important to control the viscosity and the melting point of the mould flux.
  • a CaO content greater than 35 weight% will promote the formation of Perovskite and CaO less than 15 % might induce high viscosity in the molten mould powder.
  • the content of SiO 2 should be controlled on the basis of CaO.
  • Na 2 O, K 2 O and Li 2 O will stabilize Ti in the melt and thereby as mentioned above will contribute to the prevention of Perovskite formation. This is best results are achieved when each of Na 2 O and K 2 O is present in an amount of 18-22 weight%, preferably around 20 weight%, in the mould mixture.
  • these alkali oxides promote the formation of Nepheline phase which is beneficial during casting. A very high content of these oxides will make the flux mould too fluid and a too low content would result in formation of Perovskite phase.
  • the objective of the present disclosure is also achieved by means of a method of moulding a piece of a Ni-base alloy wherein a mould flux as defined hereinabove or hereinafter is applied on a surface of the molten alloy during moulding thereof.
  • the Ni-base alloy comprises, in weight%: C ⁇ 0.05; Cr 17-23; Ni 35-63; Mo 2.5-9.5; Ti 0.3-3.0; Al 0-0.7; Si 0-0.5; Nb 0-4.5; Cu 0-3; Mn 0-0.1; S 0-0.003; P: 0-0.02; balance Fe.
