摘要： PURPOSE:To improve ultrasonic oscillation efficiency and to cast a slab having a high grade by forming the meniscus part of a wall surface opposite to the surface which is in contact with a casting metal into a main exciting part walled thinner than the wall surface over the entire width of the wall surface in the specified range of said meniscus part and forming a much thinner-walled part for coupling an oscillator horn. CONSTITUTION:The wall thickness in a specified range of the molten steel meniscus part of a base material 3 of copper plate is decreased and an oscillation input part 4 and a main exciting part 5 are formed in said part. The thickness t3 of the material 3, the thickness t2 of the part 5 and the thickness t1 of the part 4 are formed to the relation t1

摘要： PURPOSE:To decrease and to disperse the power of poured molten steel flow into wide surface range of the molten steel, by making a portion of the flow collide with a screen installed between an upward immersed nozzle and a solidifying wall, and by making the other portion of the poured molten steel flow rise upward to the surface of the molten steel. CONSTITUTION:A screen 8 is installed between an upward nozzle 7' immersed in molten steel 4 contained in a casting mold 3 and a solidifying wall 7, and the ratio l2/l1, where l2 is the breadth of the screen 8, l1 is the breadth of the flow of poured molten steel M, is set in the range about 0.1-0.6. The flow M of the poured molten steel collides with the screen 8 and divides into a flow which proceeds to the surface of the molten steel 5 and flows (m), (m) which go around the both side of the screen 8 and collide with the surface 5 of the molten steel near the point where the center of the flow M intersects the molten steel surface 5. The fluxes of divided flows (m), (m) are smaller than that of the original flow, so that their energy decreases remarkably, hence no waves are formed on the molten steel surface 5.

摘要： PURPOSE:To manufacture a low-oxygen and low-sulfur steel by a procedure in which a CaO-containing flux is blown into a deoxidized molten steel in a ladle for further deoxidization and desulfurization and then a Ca-alloy is blown into the molten steel to control the shape of sulfide present in the molten steel. CONSTITUTION:A molten steel from a steel-making furnace is deoxidized by means of Al, Fe-Si alloy, Fe-Mn alloy, etc., and then a CaO-containing flux is blown into the molten steel by means of an inert gas, e.g., Ar gas, etc., for further deoxidization and desulfurization. Then, a Ca alloy is blown into the molten steel to suppress the formation of MnS and also to form a spherical inclusion of calcium aluminate sulfide. thus, a low oxygen and low sulfur steel which is excellent in toughness and resistance to hydrogen fracture can be positively obtained.

摘要： PURPOSE:To improve the quality of molten metal at boundary part by arranging a nozzle having opening holes at side face and closing bottom face at one side and supplying the molten metal above static magnetic field zone into a mold. CONSTITUTION:The submerged nozzles 2, 3 are arranged into the molten metal pool 4 in the mold 1 and also in the nozzle 2 at upper part, the opening part 4a at the side face and the closing part 2b at the bottom face are arranged. Then, magnet forming the static magnetic field in the mold 1 is arranged at lower part of the nozzle 2. The molten metal 4a at the upper part pouring from the nozzle 2 is made to horizontal flow the opening part 2a of the nozzle, to supply into the molten metal pool 4. Then, as mixing of the molten metals 4a, 4b at the upper part and lower part is surely restrained by the magnet 7, the boundary face of the molten metals is made to clear. By this method, unstable intermediate structure at the boundary part is improved and the quality of the molten metal at the boundary part is improved.
