摘要： PROBLEM TO BE SOLVED: To produce a hot-rolled steel sheet of a high phosphors steel difficult to develop crack when a cold-rolling is applied. SOLUTION: The apparatus is provided with a drum caster 4 for casting molten high phosphorus steel 11 into a cast strip 12 at >=50 K/sec cooling speed and a hot-rolling mill 6 for hot-rolling the cast strip 14 into a hot-rolled strip 15. The hot-rolling mill 6 is provided with two work rolls 31, 32 hot-rolled in contact with the cast strip 14 and cross angles θ, θ' formed with rotating shafts 41, 42 in the work rolls 31, 32 to the width direction D are 2 degrees or larger. This casting is prevented from segregating the phosphorus in crystal grain boundary, and this hot-rolling, in which a shearing strain quantity εD in the width direction of the hot-rolled strip 15 is made 0.2 or larger is applied to prevent the crack when the hot-rolled strip 15 is cold-rolled.

摘要： An object is to provide an impeller welding method capable of avoiding a decrease in temperature when a worker joins components by welding to make an impeller and also reducing work load. The present invention relates to a method of joining a hub 11 and a shroud 12, either one of which has blades 13 integrally formed thereon, by welding. During the welding, in an upright state in which the hub 11 is placed to face a mount surface, the hub 11 and the shroud 12 are placed on top of each other to form an assembled body 10. Welding is performed on the assembled body 10 being covered with a heat insulating jacket 30 (a to g). The heat insulating jacket 30 covers the assembled body 10 except an open region (OP) and an inflow port 14 IN that are required for welding. When welding of one open region OP is completed, a new open region OP is formed by moving the heat insulating jacket 30 with respect to the assembled body, and then the next welding is performed.

摘要： A continuous casting device includes a pair of cooling rolls (1, 2) that rotate in the opposite directions to each other; a pair of side weirs (11) whose inner surface (11a) covers the end surfaces (1a, 2a) of the cooling rolls (1, 2), and whose circular surface (12b) covers the peripheral surfaces (1b, 2b) of the cooling rolls (1, 2) in which at least one of the side weirs (11) is movable in an axial direction of the cooling rolls (1, 2). The continuous casting device also includes electromagnets for forming a magnetic flux in a direction parallel with a contact surface of the side weirs (11) with the molten metal (4) along the peripheral surfaces (1b, 2b) of the cooling rolls (1, 2) at the portions opposite to the peripheral surfaces (1b, 2b) of the cooling rolls (1, 2) of the side weirs (11).

摘要： There is provided a belt coating material for a belt type continuous casting, which is capable of adsorbing the intermediate between a cast slab and the coating material to prevent the intermediate from remaining on the slab, and reducing the averaged heat flux during the casting to avoid an occurrence of cracking in a medium carbon steel. The belt coating material comprises: (1) a powder having a composition comprising 10 to 40 weight% of SiO2, 1 to 10 weight% of Al2O3, 10 to 40 weight% of CaO, 10 to 30 weight% of Na2O, 1 to 10 weight% of MgO, 10 to 20 weight% of F, and 1 to 5 weight% of LiO2, the powder being prepared by once melting the blended components, solidifying the melt, and crushing it into the powder to adjust the average grain diameter of the powder to be equal to or smaller than 10.mu.m; (2) 0.1 to 10 weight% of graphite mixed into the powder to provide a mixture, the graphite having the same grain diameter with the powder; and (3) 0.5 to 10 weight% of water glass, a viscosity increasing material, and water, each being added into the mixture so as to adjust the viscosity of the material to a predetermined value.
