  • Publication number: 20150135513
    Abstract: Provided is a method for producing a plug for use in a piercing-rolling mill for producing a seamless steel tube/pipe, and the method for producing the plug for piercing-rolling comprises shotblasting a surface of the plug, and arc-spraying a spray wire so as to form a film on a surface of a base metal of the plug that is shotblasted. In the arc-spraying step, the arc spraying is carried out by using, as the spray wire, a cored wire whose iron sheath tube is charged with at least iron oxide particles among iron particles and the iron oxide particles (one or more of FeO particles, Fe3O4 particles, and Fe2O3 particles), so as to form the film containing iron oxide and Fe. Accordingly, it is possible to enhance the production efficiency of the plug, and to produce the plug for piercing-rolling capable of securing the steady enhancement of the durability life of the plug during the piercing-rolling.

  • Publication number: 20140125677
    Abstract: The rendering device defines, based on the width of the line to be rendered on a screen comprising multiple pixels and defined by two points on the screen, an interpolation range for a line segment having its ends at the two points. The rendering device further determines whether a pixel is contained in the interpolation range. Then, the rendering device renders a line formed by the pixels on the line segment and the pixels determined to be contained in the interpolation range. Then, the rendering device can specify the pixels for rendering the line based only on information regarding the line width. Consequently, the amount of information to handle in rendering is reduced and the rendering can be expedited. Furthermore, the amount of information prepared in advance for rendering is reduced and thus the rendering device can be downsized.
