摘要： Disclosed is a continuous casting nozzle having a refractory portion formed to contain a dolomite clinker and arranged to define a surface region adapted to be in contact with molten steel, which is capable of protecting a working surface of the nozzle from alumina build-up due to alumina in molten steel, while improving corrosion resistance, even during long-term continuous casting of molten steel. The refractory portion is prepared by adding a binder to a mixed material and subjecting the obtained mixture to kneading, forming and heat treatment. The mixed material comprises a dolomite clinker which has an average particle size of 0.8 mm or less and a CaO content of 50 mass % or less. The mixed material has a ratio W1/W2 of 0.33 or more, wherein W1 is a content by mass of CaO, and W2 is a content by mass of MgO. The mixed material comprises a dolomite clinker and a magnesia clinker. Alternatively, the mixed material comprises a dolomite clinker and a magnesia clinker. The mixed material has a ratio WD/WM in the range of 0.5 to 15, wherein WD is a mass % of dolomite clinker particles having a particle size of 1 mm or less in a particle size distribution of the dolomite clinker, and WM is a mass % of magnesia clinker particles having a particle size of 1 mm or less in a particle size distribution of the magnesia clinker. Further, the mixed material has a ratio W1/W2 in the range of 0.33 to 3.0, wherein W1 is a content by mass % of a CaO component in the dolomite clinker, and W2 is a content by mass % of an MgO component in the magnesia clinker.

摘要： A blade of an exposure control such as an iris control device or a shutter control device is provided for use in cameras. A sheet of a resin or metallic material configured as desired into the final blade form is placed in an injection molding machine which has a pin-forming cavity on one side of the sheet. The sheet is broken and penetrated at its portions where pins are to be formed and fixed, such that portions of the material of the sheet are deformed to project into the cavity. A molten resin is injected through a sprue formed on the opposite side of the sheet to the cavity so that the injected resin fills the cavity to form a pin in such a manner that the deformed and projected portion of the material of the sheet is embedded in the pin-forming resin. Another pin is formed on the other side of the sheet simultaneously with the first-mentioned pin in the same manner in the same die apparatus.

摘要： An exhaust system for a steam turbine provided with an improved annular flow guide in a high or intermediate turbine. The improved flow guide reduces flow turbulence in an exhaust hood and reduces pressure loss to thereby improve turbine plant efficiency.The shape (vertically symmetric) of a flow guide 5A according to a conventional technology was modified into the shape (vertically asymmetric) of a flow guide 5 such that the length of a downstream flow guide portion 5d is greater than that of a upstream flow guide portion 5u. Numerical analyses were performed to find the optimum flow guide occupation ratio of the conventional technology and the corresponding total pressure loss coefficient. The obtained values were used as reference values. Further, the flow guide occupation ratio of the upstream flow guide portion 5u was set at 0.4 and the flow guide occupation ratio of the downstream flow guide portion 5d was set at 0.7; at values where the total pressure loss coefficient becomes lower than the reference value. The rectification effect of the flow guide can thus be enhanced.

摘要： Disclosed is anti-alumina-buildup refractories for casting nozzles, which comprises a refractory aggregate including 20 mass % or more of CaO component, and 10 mass % or more of clinker particles each containing CaO as a mineral phase, on the basis of 100 mass % of the entire composition. At least a part of the surfaces of the CaO exposed from the surfaces of the corresponding clinker particles is formed with a CaCO3 film. The CaCO3 film releases CO2 gas through thermal decomposition to smooth an operative surface of the nozzle so as to prevent the accretion of metal thereon, so that CaO is continuously supplied to alumina attached on the operative surface to prevent alumina buildup. In addition, the CaCO3 film effectively prevents the hydration of CaO due to a hydration reaction.
