摘要： A method for manufacturing a hot-dip galvanized steel sheet having a high Si content and good plating adhesion. The method for manufacturing a hot-dip galvanized steel sheet includes the following: hot-rolling a steel raw material having a Si content of 1.0 mass % or more and coiling a steel sheet at 500° C. to 700° C.; subjecting a surface of the steel sheet after the coiling to an oxidation treatment at a heating temperature of a steel sheet temperature of 750° C. or lower, and subsequently subjecting the surface to a reduction treatment; and subjecting the steel sheet after the reduction treatment to a hot-dip galvanizing treatment to form a Zn-plated layer on a surface of the steel sheet.

摘要： A method for producing pig iron may use a blast furnace with a tuyere. Such a method may include: charging a first layer containing an iron ore material and a second layer containing coke alternately in the blast furnace; and reducing and melting the iron ore material in the charged first layer while injecting an auxiliary reductant into the blast furnace by hot air blown from the tuyere. An aggregate containing a reduced iron molded product obtained through compression molding of reduced iron may be blended into the first layer. The iron ore material may contain iron ore pellets as a principal material. An average basicity of the reduced iron molded product may be less than or equal to 0.5, and an average basicity of the iron ore pellets may be greater than or equal to 0.9.

摘要： A target shape is set from a three-dimensional shape data of an additively-manufactured object, and the set target shape is sliced into a plurality of bead models having shapes corresponding to weld beads. A dripping amount of a filler metal to a lower layer during bead formation in a bead deposition portion where the sliced bead models overlap vertically is predicted according to welding conditions of the weld beads. A bead height of each bead model in the bead deposition portion is modified according to the predicted dripping amount. A deposition plan to manufacture the additively-manufactured object is created by using the plurality of bead models including the bead model with modified bead height.
