TAPER SHAPE DETERMINATION METHOD AND PATH SCHEDULE SETTING METHOD
This method for determining a taper shape of an intermediate roll (10) in a six-stage rolling mill (1) equipped with an intermediate roll shift mechanism (2) comprises: an input step for inputting conditions, other than those for the taper shape, which are necessary for determining a shape control region indicating a range in which shape control can be performed on a rolled material (8); and a determination step for determining the taper shape so that the shape control region includes the origin of a two-dimensional plane of coordinates both under a first condition where a load exerted per unit width of the rolled material (8) is minimized, and under a second condition where the load exerted per unit width is maximized.
The present invention provides a calculation device and a calculation method that are able to set an influence coefficient in order to obtain a fine rolling shape through cold rolling. This calculation device is provided with a variation calculation unit (23) which determines the level of change in elongation percentage difference caused by correction, between multiple locations of a rolled material (8), and which, at the same time, calculates a correction value using a mathematical expression that includes the correction value as a variable, wherein the mathematical expression includes an influence coefficient indicating a degree of influence exerted on the elongation percentage difference by a shape control mechanism, and the influence coefficient is represented by a function that includes, as variables, a load applied per unit width of the rolled material (8) and the width of the rolled material (8).
This metal roofing material is provided with the following: a front base material 2 that includes a body part 20 made from a metal plate and formed in a box shape; a rear base material disposed on the rear side of the front base material 2 so as to close the opening of the body part 20; and a core material filled between the body part 20 and the rear base material. The metal roofing material is aligned and disposed on a roof substrate along with other metal roofing materials. At least one projecting edge display part 22 is provided to the edge part of a top panel 20a of the body part 20.
Provided are a ferritic stainless steel sheet with good surface quality and for which discoloration due to heating can be prevented, and a manufacturing method therefor. The present invention is a ferritic stainless steel sheet that is temper-rolled after bright annealing and has a passivation film. The area ratio of micro-defects with areas of at least 10 µm2 in the steel sheet surface is 0.2%-1.5%. The thickness of the passivation film is 1 nm-10 nm. The average Si concentration in the passivation film is 10 at%-20 at%. The ratio of average Si, Al, Cr and Fe concentrations in the components of the passivation film is (Si+Al+Cr)/Fe>1.0. When producing said ferritic stainless steel sheet, a hot-rolled acid-washed material is used as starting material. The steel sheet surface is polished at least one time in a previous step by finish cold-rolling after which annealing is performed. After said annealing, finish cold-rolling, bright annealing and temper-rolling are performed in order.
