摘要: The invention relates to a method for re-melting coated aluminum alloy scrap comprising a step of supplying shredded coated aluminum alloy scrap, consisting of individual entities; a decoating step, a step of preparing a heel, a step of loading and melting the decoated scrap on the heel. The invention is characterized in that the scrap has a specific geometry wherein at least 50% of the individual entities of the shredded coated scrap has a fold ratio (R) of less than or equal to 0.6, wherein the fold ratio (R) of an individual entity is defined by: fold ratio=R=(unfolded area−folded area)/(unfolded area), wherein the folded area is the maximum area of the orthogonal projection of the individual entity onto a plane and the unfolded area is the total area of the same individual entity after it has been unfolded.

摘要: Provided is steel for a wind power gear with improved purity and reliability. The chemical components thereof comprise, in percentages by mass: 0.15-0.19% of C, ≤0.4% of Si, 0.5-0.7% of Mn, ≤0.012% of P, ≤0.006% of S, 1.5-1.8% of Cr, 0.28-0.35% of Mo, 1.4-1.7% of Ni, and 0.02-0.04% of Al, with the balance being Fe and inevitable impurities. A smelting method therefor comprises adding raw materials to a converter for primary melting, transferring same to a refining furnace for refining, carrying out continuous casting after vacuum degassing, and transferring same to a gas protection furnace for electroslag remelting. According to the present invention, a pure electroslag master batch is obtained by continuous casting, and the purity of the material is further improved by means of an electroslag remelting procedure; and the prepared steel material is used in a wind power gear, such that the flaw detection pass rate is significantly increased, large-particle inclusions in the steel material are significantly reduced, and the inclusions are fine and dispersed.

摘要: Various non-limiting embodiments disclosed herein relate to nozzle assemblies for conveying molten material, the nozzle assemblies comprising a body, which may be formed from a material having a melting temperature greater than the melting temperature of the molten material to be conveyed, and having a molten material passageway extending therethrough. The molten material passageway comprises an interior surface and a protective layer is adjacent at least a portion of the interior surface of the passageway. The protective layer may comprise a material that is essentially non-reactive with the molten material to be conveyed. Further, the nozzle assemblies according to various non-limiting embodiments disclosed herein may be heated, and may be self-inspecting. Methods and apparatus for conveying molten materials and/or atomizing molten materials using the nozzle assemblies disclosed herein are also provided.
