摘要： The conventional techniques cannot minimize increase in yield loss and slab thickness caused by unsteady deformation in top and rear end portions during reduction of the width of a slab, and cannot shape a slab with desired target dimensions at high productivity. With respect to a width pressing machine 2 that reduces the width of a slab, a horizontal rolling mill 1 is arranged at the upstream side of the slab conveying direction, or an entry-side horizontal rolling mill 1 and an exit-side horizontal rolling mill 3 are respectively arranged at the upstream side and downstream side. A slab shape control equipment thus configured is used to simultaneously perform rolling by the horizontal rolling mill 1 or by horizontal rolling mill 1 and horizontal rolling mill 3, and reduce the width of a slab by the width pressing machine 2 on one hot slab 10.

摘要： A high-strength cold-rolled steel sheet having a tensile strength of 340 MPa or more, which can certainly prevent occurrence of galling, can be manufactured even if a large number of the steel sheets are continuously press-formed. This is because a surface texture thereof is controlled so that the surface texture includes flat areas in which a roughness profile has a deviation of ± 2 µm or less from a filtered waviness curve and a dented portion having a maximum depth between 10 µm and 50 µm from the filtered waviness curve, wherein an average area of the dented portion is more than 0.01 mm 2 and 0.2 mm 2 or less, and an area fraction of the dented portion relative to the entire surface thereof is 5% or more and less than 20%.

摘要： There is provided a method for manufacturing a hot-rolled steel sheet having a large thickness and a large width, in which a steel sheet having a larger sheet thickness, a larger sheet width and a lower temperature can stably be cut at a cutting load equal to that of a conventional steel sheet having a usual sheet thickness, a usual sheet width and a usual temperature. In a rough rolling step, a shape of a crop portion formed at a front end of the steel sheet in a conveying direction is adjusted into a fishtail shape by width rolling of a width rolling machine and horizontal rolling of a horizontal rough rolling machine, the steel sheet is formed so that the shortest length L (mm) from a concave portion bottom to a convex portion top of the fishtail shape satisfies Equation (1) mentioned below, and an intermediate portion between the concave portion bottom and the convex portion top, defined as a desired cutting location, is cut: 2 X + 30 ≤ L ≤ 300 in which X is a maximum deviation (mm) of the cutting location of a crop cutting machine and 0 ≤ X ≤ 90.
