摘要： PURPOSE:To produce stably an amophous ribbon having an end face of good shape by ejecting molten metal from the short and slender nozzle hole in a closing part in such a way that the value obtd. by dividing the ejection pressure by the aperture area of the slit hole attains a specified value or above. CONSTITUTION:A pipe material 1 is drawn from both sides to form a slender nozzle hole 2 and a nozzle is thus formed in a device wherein the molten metal is ejected from the nozzle toward a cooling roll under high speed rotation, is cooled quickly and solidified on the roll and an amorphous ribbon is produced. The lengths W of the respective closing parts 4, 4 from the end of the drawn part 3 to the end parts on the same side of the nozzle hole 2 are formed roughly to =20kg/cm , whereby an amorphous ribbon is produced.

摘要： PURPOSE:To provide a titled device by which a thin amorphous metallic strip having a uniform thickness and good surface characteristic is obtained by providing a shielding body which shields the high velocity gaseous flow directing toward a nozzle for supplying molten metal on a roll under high speed revolution. CONSTITUTION:The molten metal alloy 2 in a nozzle 3 in an electric furnace 4 is supplied through the nozzle 3 onto a roll 1 under high speed revolution in an arrow direction, whereby the molten alloy is solidified quickly and a thin amorphous metallic strip is made. A shielding body 8 which shields the gaseous flow 7 generated by the rotation of the roll 1 and directing toward the nozzle 3 is provided on the side opposite from the rotating direction of the roll when viewed from the nozzle 3. Of the flow 7, the gaseous flow 71 passing on the outer side of the roll 1 is kept apart from the roll 1 by the upper wall 83 in the large opening part 81 of the body 8. On the otherhand, the gaseous flow 72 passing on the inner side is conducted through the part 81 to an opening part 82, where the flow is turned into jets and is ejected toward the direction of the flow 7, thereby hindering the advance thereof and moving the flow apart from the roll 1. As a result, the inclusion of the molten metal supplied from the nozzle 3 is obviated, the size of the paddle of the molten metal is stabilized and the thin amorphous metallic strip having good quality is obtained.

摘要： PURPOSE:To improve surface characteristics and to make the thickness of a tape uniform by injecting molten metal onto a rotary roll which is provided with high-speed revolving fans in the recesses on the side surfaces thereof and communicating holes on the outside edges of the roll. CONSTITUTION:A rotary roll 4 which is provided with recesses 6 on the side surfaces and is provided with fans 9 revolving at a speed higher than the rotating speed of the roll 4 in the recesses 6 is installed. Through-holes 8 communicating with both outside edges of the circumferential surface 7 of the roll 4 are punched on the circumference in a large number. The roll 4 is rotated and molten metal is ejected from a slit 2 provided right above the roll 4, whereby molten metal 3 is cooled quickly. Thus, the amorphous metal having excellent surface characteristics is produced with uniform thickness.

摘要： PURPOSE:To make continuous production possible and to stabilize quality by injecting molten metal to a rotary roll which is held at a low temp. by means of fans provided in the recesses on the side surfaces of said roll. CONSTITUTION:A roll 4 which is provided with recesses 6 on side surfaces 5 and is provided with fans 7 in the recesses 6 is installed right under a slit 2. The roll 4 is rotated at a high speed and molten metal 3 is injected from the slit 2 onto said roll, whereby the metal 3 is cooled quickly. The amorphous metal having smooth surface characteristics is obtained continuously.

摘要： PURPOSE:To obtain an amorphous metal having excellent corrosion resistance and high strength by subjecting a metal blank to a plastic working in the optimum plastic working region which is limited by a specified heating period of time for the blank and a specified working temperature in a chart on semilogarithmic coordinates with the heating period of time taken in logarithmic scale on the ordinate and the working temperature on the abscissa. CONSTITUTION:A method for a metal-metalloid amorphous alloy at a high temperature. On semilogarithmic coordinates with a logartithmic scale on the ordinate, the heating period of time Y (sec) for the metal blank is taken on the ordinate, the working tenperature X ( deg.C) is taken on the abscissa, the intersection of the straight horizontal line representing the working period of time of 14 sec with the straight vertical line representing the working temperature of 400 deg.C is denoted as P1, and the intersection of the straight horizontal line representing the working period of time of 5sec with the straight vertical line representing the working temperature of 500 deg.C is denoted as P2. In this chart, the region lying below the strainght line P1P2 and bounded within the temperature range of 400-500 deg.C is made to be the region for the plastic working.
