摘要： A method and an apparatus, wherein heat can be effectively transferred to molten metal contained in a reaction vessel. The pressure of the gaseous atmosphere within the vessel is maintained higher than atmospheric pressure. Oxygen gas is blown to a layer of molten slag contained in the vessel through tuyeres set in the reaction vessel, thereby to achieve post-combustion therein. The pressure in the vessel is controlled within the range of 2.0 to 5.0 kg/cm.sup.2 by a pressure regulator.

摘要： A molten metal pouring nozzle for a continuous casting machine having an endless-travelling type mold, wherein the endless-travelling type mold is formed with two pairs of opposing wall members endlessly travelling in the same direction and at the same speed, and one end of the pouring nozzle is connected to a tundish for receiving molten metal, and the other end of the pouring nozzle is inserted into the mold. The molten metal pouring nozzle of the present invention comprises a nozzle body made of a refractory and a flow regulator made of a refractory. The nozzle body (14, 20) has a bore (1a, 3a), through which molten metal flows, along the axial line thereof, and the sectional area of the downstream end portion of the bore (1a, 3a) becomes gradually larger toward the downstream end thereof. The flow regulator (15, 18) is arranged at the center of the downstream end portion of the bore (1a, 3a) of the nozzle body (14, 20). The flow regulator (15, 18) forms, in cooperation with the bore (1a, 3a), a path for molten metal, by which molten metal flowing through the bore (1a, 3a) impinges against the inner surface of the mold, near the downstream end of the nozzle body (14, 20).

摘要： A method for manufacturing alloy comprising: allowing a consumable electrode consisting a single metal element to form a pair of electrodes which have the same element, to set plurality of the pair so that an electrode metal element of each of the plurality of the pair may be different from one another; generating arc between the electrodes in a non-oxidizing atmosphere, to allow the consumable electrodes to be melted at their top ends; and allowing molten drops produced by the melting to go down into a mold to form molten metal, and the molten metal to be cast into alloy consisting of two metal elements. Two pairs consisting of the consumable electrodes allow the two consumable electrodes to be set on an axis, with a predetermined distance between their top ends, on horizontal plane above the mold.The two pairs of the consumable electrodes are alternated by three pairs of the consumable electrodes when alloy consisting of three metal elements.
