    摘要： A method for removing burr in a continuous rolling process of the first aspect of the present invention comprises the steps of: joining the rear end of a preceding billet (10) with the front end of a succeeding billet (10) using the flash butt welding method while running both thereof; and grinding a burr on the welded part of the joined portion using a plurality of grinders (31) while the billets running and while rotating the grinders and moving thereof synchronously with the travelling speed of the billets. and
    A grinding machine for continuously rolling a round billet (20) comprises: a travelling body (11) shuttling along the direction of the round billet movement; a turret ring (55) supported by the travelling body in a rotatable state thereof; a plurality of grinding devices (51) arranged in a movable manner within a radius of the turret ring; and grinders (31) of the grinding device, which are set at a tilted angle against the center axis of the turret ring.

    摘要： Provided is a titanium cast product for hot rolling made of commercially pure titanium, the titanium cast product including a melted and resolidified layer in a range of more than or equal to 1 mm in depth on a surface serving as a rolling surface, the melted and resolidified layer being obtained by adding one or more elements out of any one of or both of at least one α stabilizer element and at least one neutral element to the surface, and melting and resolidifying the surface. An average value of a total concentration of the at least one α stabilizer element and the at least one neutral element in the range of more than or equal to 1 mm in depth is higher than a total concentration of the at least one α stabilizer element and the at least one neutral element in a base metal by, in mass%, more than or equal to 0.1% and less than 2.0%.

    摘要： The production method of a round bar for a seamless tube in which a continuously cast slab with a rectangular cross section, and made of high alloy containing Cr of 20 to 30 mass%, Ni of 30 to 50 mass%, and at least one of Mo and W as Mo + 0.5W of 1.5 mass% or more is subjected to a blooming and billet-making process to yield a round bar having a diameter of 150 to 400 mm as a starting material of the seamless tube; characterized in that the blooming and billet-making process is carried out under a condition satisfying a relation of 1.3≤H/D≤1.8 where a short side length of the cross section of the cast slab is defined as H (mm), and the diameter of the round bar is defined as D (mm). The round bar produced in this manner is subjected to piercing-rolling to make a hollow blank, and this hollow blank tube is subjected to elongation-rolling, further followed by diameter-adjusting-rolling to make a seamless tube made of high Cr-high Ni alloy, thereby preventing occurrence of the tube end cracking during piercing-rolling, and producing the seamless tubes in preferable yields.
