  • Publication number: 20130129924
    Abstract: Exemplary embodiments of the present invention can provide a hot dip galvannealed steel sheet which has excellent corrosion resistance, workability, coatability and appearance. The exemplary galvannealed sheet can include an ultra-low carbon steel sheet having a plating layer which includes about 8 to 13% Fe, about 0.05 to 1.0% Ni, about 0.15 to 1.5% Al, and a balance of Zn and unavoidable impurities. An exemplary method for producing a hot dip galvannealed steel sheet is also provided which can include cleaning an annealed ultra-low carbon steel sheet, preplating it with Ni, rapidly heating the sheet in a nonoxidizing or reducing atmosphere, plating the sheet in a galvanization bath containing Al, wiping it, then rapidly reheating it and either cooling the sheet without any soaking time or soaking and holding it for less than 15 seconds and then cooling it.

  • Publication number: 20130039722
    Abstract: A metal band having metallic appearance and being excellent in forming stability is provided. The metal band includes a coating film containing not less than 20 mass % in the coated and dried state, of filler of aluminum or aluminum alloys on the side thereof corresponding to the outside of a can. The metal band also has a resin-rich portion containing not more than approximately 5 mass % of the filler, approximately 0.1 to 20 ?m in thickness in the coated surface far from the metal strip surface, seamlessly-formed can bodies made of such strips. Methods for manufacturing such strips and can bodies are also provided.

  • Publication number: 20130037233
    Abstract: An apparatus and a method for producing an amorphous alloy foil strip, which are capable of producing an amorphous alloy foil strip having a large sheet thickness in an industrial scale, are provided. A production apparatus 101 for an amorphous alloy foil strip S includes: a pair of cooling rolls 113a and 113b; a driving unit 111 configured to rotate the cooling rolls; and a crucible 114 configured to supply a molten alloy sequentially to an outer circumferential surface of the cooling roll 113a and an outer circumferential surface of the cooling roll 113b. The crucible 114 is movable along a moving unit 116. A molten alloy is supplied alternately to the cooling roll 113a and the cooling roll 113b while rotating and water-cooling the cooling rolls 113a and 113b.

  • Publication number: 20130020836
    Abstract: Provided is a coupling structure between a front pillar and a side sill of an automobile, which improves the steering stability of the automobile and realizes a high productivity. A reinforcing member 8 is provided inside a front pillar 1 having a closed cross-section so as to extend in the front-rear direction of the automobile. The reinforcing member 8 is coupled to a front pillar outer 2. An end portion of the reinforcing member 8 at the rear side of the automobile is extended toward a side sill 4 to form a reinforcing member extension 8a. The reinforcing member extension 8a is coupled to a side sill outer 5.
