    摘要： An ingot I made of a light alloy is produced using a continuous casting apparatus including a cylindrical water-cooled casting mold which is disposed immediately below a spout having an upward-turned molten metal receiving port and a downward-turned molten metal outlet, and which has an inside radius r1 larger than an inside radius r2 of the molten metal outlet, and lubricating oil discharge passages provided below the spout to supply a lubricating oil to between the water-cooled casting mold 13 and a molten metal m brought into contact with the water-cooled casting mold. In this production, a lubricating oil having a vaporization rate of 30% or more at 300° is used, and an annular gas accumulation for spacing the molten metal apart from outlets of the lubricating oil discharge passages is defined below an annular protrusion of the spout by vaporization of the lubricating oil. Thus, it is possible to avoid the generation of a casting skin failure in a light alloy ingot due to the outlets of the lubricating oil discharge passages.

    摘要： An agitated continuous casting apparatus includes a spout having an upward-turned molten metal receiving port and a downward-turned molten metal outlet, a cylindrical water-cooled casting mold disposed immediately below the spout, and an agitator for applying an electromagnetic agitating force to the molten metal in the spout. The agitator has a function to form, in the spout, an upper area for moving the molten metal in a substantially radiate direction, and a lower area for rotating the molten metal in a circumferential direction. An upper area forming portion of an inner peripheral surface of the spout is formed into a tapered shape with its inside diameter gradually increased from its upper peripheral edge toward its lower peripheral edge. Thus, the molten metal moved in the substantially radiate direction to collide against the upper area forming portion can be moved toward the lower area, and crystallized products having a higher melting point in the molten metal can be spheroidized and collected into an outer periphery of a continuous casting material, and a shape retention effect of the crystallized products can be utilized. Therefore, the continuous casting material has a good rheologic property and an excellent shape maintaining property in its semi-molten state.

    摘要： A fuel cell is formed by stacking a membrane electrode assembly and separators alternately. Each of the separators includes first and second metal plates. A coolant flow field is formed between the first metal plate of the fuel cell and the second metal plate of the adjacent fuel cell. A folded section is provided around a coolant supply passage by folding the second metal plate. The folded section forms an inlet which enlarges the sectional area of an opening as a fluid passage between the coolant supply passage and the coolant flow field.

    摘要： A method for treating the surface of a stainless steel product for a fuel cell containing, in wt %, 0.15% or less of C, 17 to 36% of Cr, 0.005 to 3.5% of B, which comprises the first step of forming in advance a passive film with an oxidizing acid on the surface of the stainless steel product, the second step of allowing an aqueous acid solution to corrode the passive film, to thereby project one or more of a M23C6 type carbide, a M23(C, B)6 type borocarbide and M2B type boride, which are inclusions having good electroconductivity, the third step of forming a passive coating film with an oxidizing acid on the surface of the steel product except that of the inclusion above projected, and the fourth step of washing with water and drying. The method of treatment allows, without the use of a method requiring a high cost such as gold plating, the improvement in the contact resistance of the stainless steel product for a fuel cell, which results in the retention of excellent characteristics of a stainless steel product over a long period of time.
