摘要： PURPOSE:To improve resistance to thermal impact and resistance to wear, by a method wherein a nozzle is made of a specified material, and heating treatment is applied thereon. CONSTITUTION:A flow uniformizing plate 13, removably attached to a multistage body 1, is formed by chrome-nickel series steel, and the part on the upper stream side of said flow uniformizing plate is age-hardened by high-temperature heating. The chrome-nickel series steel is age-hardened by high-temperature heating and therefore, 25Cr-20Ni, 45Cr-30Ni, 50Cr-50Ni are used. The flow uniformizing plate 13 is formed such that hardening process is not applied on a front 13a, needing resistanc to thermal impact, the hardness thereof is set to HB300 or less, and only a rear 13b, needing resistance to wear, is age-hardened at 600-900 deg.C to set the hardness to HB500 or more. Thus, the front 13a of the uniformizing plate 13 is low in hardness and is formed by a material having excellent ductility, and thereby, even if crack extends to a corner part, the crack is prevented from extending to the front 13a of the flow uniformizing plate 13.

摘要： PURPOSE:To cast a thin metallic sheet stably and continuously by constituting a continuous casting device of a horizontal mold of a hollow shape in cross section provided with a cooling means on the bottom surface. CONSTITUTION:Beforehand a dummy bar is loaded into a mold 14, and molten carbon steel 12 is poured through a charging port 11. The molten metal 12' poured int the mold begins to solidify from the bottom surface as said metal is deprived of heat by cooling water 18 through heat resistant and abrasion resistant materials 13 and the mold 14. The molten metal solidifies in the form of enclosing the dummy bar thereon. If the dummy bar is pulled by operating pinch rolls 17 in the stage when the poured metal 12' is filled in the mold 14, a solidified ingot 16 is drawn, and a carbon steel plate is obtained stably and continuously. In order to prevent oxidation of the metal 12', gaseous argon is run in a space 20, and in order to reduce the temp. of the ingot 16, compressed air is blown through cooling pipes 15.

摘要： PURPOSE:To offer a metallic material which can prevent and suppress fouling with marine organisms, by adding specified amounts of Mn and other metals into Cu. CONSTITUTION:A Cu alloy containing 5-30% of Mn and at least one component of less than 5% Sn, less than 8.5% Al, less than 7.0% Zn, less than 2.5% Fe and less than 2.5% Ni is prepared by melting. An ingot made of the Cu alloy is hot forged, and then annealed at 600 deg.C. When the alloy is cast, the alloy has a single alpha-phase (face-centered-cubic lattice) as cast. If the alloy is not composed of the single alpha-phase, the alloy is converted into the single alpha-phase by heating at 550- 850 deg.C and then rapidly cooling. Owing to the formation of the single alpha-phase structure, fouling with marine organisms can be prevented or suppressed.

摘要： PURPOSE:To reduce a construction period, by welding a manhole cylindrical body to a bulkhead, mounting removable covers to both end openings and introducing compressed air to the inside of the cylindrical body of a construction manhole or the like provided between an engine compartment and a pump chamber of a ship. CONSTITUTION:A manhole cylindrical body 4 closing both end openings by manhole covers 5, 5 is air-tightly provided by welding to a bulkhead 1 between an engine compartment in the safety section and a pump chamber in the hazardous section, and a compressed air pipe 8 through a solenoid valve 9 while a fire-extinguishing substance pipe 14 through a solenoid valve 15 are connected and a pressure switch 11 and a gas detector 13 are arranged to said cylindrical body 4. When a manhole is used for a work hole, the covers 5 are removed by bolts 6, on the contrary when the manhole is not used, to prevent an inflow of hazardous gas to the engine compartment from the pump chamber, compressed air is fed into the cylindrical body to a pressure higher than the pressure of the pump chamber, and a fire-extinguishing substance is fed by a signal of the detector 13 even if hazardous gas is mixed in the cylinder. In this way, construction of an explosion-proof manhole as a work hole is obtained, and a period of construction can be decreased.

摘要： PURPOSE:To make continuous casting of a thin metallic sheet easy and sure by acting a uniform pressure of the melt of an inorg. material upon the top surface of the molten metal supplied on the surface of a water cooled mold of a flat plate shape. CONSTITUTION:The molten metal 12 in a tundish 11 for molten metal flows out through a molten metal outflow hole 13 onto the mold surface 14a of a water cooled mold 14. A uniform pressure is acted upon an ingot 16 which is cooled and solidified on the mold surface 14a of a flat plate shape, by the differential pressure generated by a difference between the head of the molten metal 12 in the tundish 11 and the head of the melt 18 of an inorg. material in a tundish 20 for the melt of the inorg. material. While the ingot 16 is formed to a uniform thickness, the ingot is drawn to the outside through an ingot drawing port 14c, and is rolled with rolling roll devices 25. In this case, the thickness of the ingot 16 is determined by the pressure of the melt 18.

摘要： PURPOSE:To obtain abrasion resistant double rolls of improved melt-sticking of inside and outside layers for mills, etc. by limiting the inside surface temps. of Ni- hard type cast iron or high chromium type cast iron of the outside layer and the wall thickness of the cast steel of the inside layer in double centrifugal casting. CONSTITUTION:An outer layer is first cast by centrifugal cast method by using Ni-hard type cast iron or high chromium type cast iron. When the inside ring surface temp. of the outside layer attains 700-900 deg.C after solidification, an inside layer is cast by using ordinary cast iron at wall thickness of 1/4-3/4 the wall thickness of the outside layer material. According to this method, the double centrifugal cast rolls free from the high temp. cracking of the surface of the outside layer material and lack of fusion of both inside and outside layers are obtained. Since such rolls are superior in abrasion resistance, the frequency of replacing rolls is reduced if they are used for grinding mills for ore, coal, cement, etc.
