摘要： Phosphorus is removed from metals or alloys esp. from iron melts contg. metal(s) which can be oxidised more readily than iron, by adjusting the carbon content to a value below the satn. limit, and treating the melt (I) in a non-oxidising atmos. with a P-removing compsn. (II) based on CaC2 (3-90%) and >=1 alkaline earth metal halide (>=10%). The compsn. (II) may contain 3-50% of Ca and/or its alloy (calcd. as Ca), pref. Ca-Si, Ca-Si-Mn and/or Ca-Si-Fe. The method is esp. suitable for P removal from Cr steels, in which P adversely effects the corrosion resistance, workability and weldability. CaC2 decomposes, and Ca reacts with P forming Ca3P2 which passes into the slag; whilst C dissolves in the Fe (the latter must be unsatd. w.r.t. carbon). The process is rapid and economical.

摘要： In this process, the amt. of carbon and nitrogen in powdered ferro-chromium is reduced by forming an oxide film on the surface of the alloy, followed by heating for 3-20 hrs. in H2 at 1000-1300 degrees C. The initial material pref. contains max. 0.1% C and is either pulverised mechanically to 2 mm max. size and given an oxide film is not >1 mu thick, or a molten bath is atomised to shot 0.05-1 mm size using is not >5% O2 in the atmos. and is not >1.5 ml O2/l in the water, at 20 degrees C., used for shotting and cooling, to obtain an oxide film is not >2 mu thick. The H2 should pref. be used at min. 3 1/minute and contain the lowest possible amt. of N2 with max. 5% H2O, and the final alloy should pref. contain, all maxima, 0.005% C, 0.015% nitrogen and 0.1% oxygen. The powdered alloy is used in the mfr. of stainless steel, the corrosion-resistance and toughness of which is improved by a redn. in the C and N2 content. Process uses a lower temp. and shorter time than similar, known processes which involve heating in vacuo and do not produce very low nitrogen contents.

摘要： PROBLEM TO BE SOLVED: To provide an underground heat exchanger capable of considerably shortening the step compared with that of a known underground heat exchanger, and considerably suppressing the construction cost, and a highly efficient energy system using the underground heat exchanger. SOLUTION: A hollow tubular body 1 is embedded by rotating and press-fitting the hollow tubular body 1 with a rotary blade 2 fitted to a lower end portion thereof by applying the rotational force and the downward force to the hollow tubular body. A bottom lid 3 is provided on a lower end portion or an intermediate portion in the hollow tubular body 1 to close the inside of the hollow tubular body 1, and the underground heat exchanger is constituted by utilizing an internal space of the hollow tubular body 1. The highly efficient energy system utilizes the underground heat exchanger. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PURPOSE:To obtain a carrier for an exhaust gas catalyst capable of withstanding under severe environment by a method requiring no additional soldering work, by integrating a honeycomb carrier matrix with a cartridge comprising an outer cylinder by diffusion treatment and subsequently oxidizing the integrated one to convert the same to alumina. CONSTITUTION:Al-foils 2 are laminated to the upper and lower surfaces of a honeycomb substrate 1 through a reducing agent 3, and the flat plate and the corrugated board both of which are made of this laminated material are formed into a roll shape or molded in a laminated state to be set to an outer cylinder and, thereafter, the whole is subjected to diffusion treatment at 300-650 deg.C under vacuum or a reductive atmosphere to be integrated. Subsequently, in order to obtain a catalyst carrier covered with Al2O3 being a high m.p. substance excellent in oxidation resistance, the integrated one is subjected to oxidation treatment at 800-1,000 deg.C in the atmosphere to be converted to alumina. By this method, all of the contact points of the flat plate and the corrugated board each being the honeycomb substrate can be perfectly bonded.
