発明の名称 (英語) Metal jet apparatus and jet method 実績あり
発明の概要(英語) A metal jet apparatus comprises a discharge nozzle 31 for jetting molten metal 20, and a gas passage 33 for supplying inert gas to a peripheral portion of a discharge port 32 of the discharge nozzle 31.
The discharge port 32 of the discharge nozzle 31 and an outlet of a gas passage 33 are provided with a nozzle cover 34.
The nozzle cover 34 includes a space 35 which is in communication with the discharge port 32 and the outlet of the gas passage 33, and which opens downward.
A ring-like projection 36 is disposed around the opening.
When the molten metal 20 is jetted from the discharge port 32 into the space 35, the inert gas is supplied to the space 35, thereby preventing the molten metal 20 from being oxidized, and it is possible to prevent the nozzle of the discharge port 32 from being clogged, and to form the molten metal 20 into a spherical shape.
特許請求の範囲(英語) [claim1]
1. A metal jet apparatus for jetting spherical molten metal droplets, the metal jet apparatus comprising: a discharge nozzle provided therein with molten metal,
a discharge port for jetting said molten metal from one end of said discharge nozzle, and
a pressing body for pressing said molten metal from the other end of said discharge nozzle in which said pressing body intermittently presses said molten metal in said discharge nozzle and jets said molten metal from said discharge port,
wherein said discharge nozzle includes a curved surface shaped inner wall which forms a focal point at said discharge port or in the vicinity of said discharge port, and
said molten metal jetted from said discharge port is spherical molten metal droplets.
[claim2]
2. A jet apparatus according to the metal jet apparatus in claim 1, wherein said molten metal is replaced by a mixture of liquid and metal powder or non-metal powder, or liquid.
