Description

回転軸心周りに回転する筒状金型内にその一端口から注湯装置によって溶湯を流し込み、前記筒状金型による遠心力によって、前記溶湯を前記筒状金型内の周面に沿わせながら凝固させる遠心力鋳造方法、及び、内側に注湯空間を形成する遠心力鋳造用の筒状金型を設け、前記筒状金型をその軸心周りに駆動回転自在に支持する支持ローラーを設け、前記筒状金型の一端口に挿入する吐出口を備えた注湯装置を設けてある遠心力鋳造装置及び鋳造管に関する。   The molten metal is poured into the cylindrical mold rotating around the rotation axis by a pouring device from one end of the cylindrical mold, and the molten metal is caused to follow the circumferential surface in the cylindrical mold by the centrifugal force of the cylindrical mold. A centrifugal casting method for solidifying while providing a cylindrical mold for centrifugal casting that forms a pouring space inside, and a supporting roller that supports the cylindrical mold so as to be driven and rotated around its axis. The present invention relates to a centrifugal casting apparatus and a casting pipe provided with a pouring device provided with a discharge port to be inserted into one end port of the cylindrical mold.

従来、遠心力鋳造技術は、一般的に筒状金型の一端口に取鍋からの溶湯を受けて流し込む樋からなる注湯装置を設け、その注湯装置から溶湯の自然流下で筒状金型内に注湯していた（例えば、特許文献１参照）。   Conventionally, the centrifugal casting technology has generally provided a pouring device consisting of a bowl that receives molten metal from a ladle at one end of a cylindrical mold, and the cylindrical mold is formed under the natural flow of molten metal from the pouring device. Hot water was poured into the mold (see, for example, Patent Document 1).

特開平６−８７０５８号公報JP-A-6-87058

上述した従来の遠心力鋳造方法及び鋳造装置では、筒状金型が小口径でしかも長尺になればなるほど、溶湯を一端口から他端口まで流して供給するのが困難になり、途中で金属が凝固したり、十分な量の溶湯が他端部まで届かなかったりする問題点があった。つまり、筒状金型が小口径になれば、注湯量も少なく、湯先に到達するまでに湯温低下が生じやすく、また、注湯装置の吐出口の口径も小さくなるために、鋳込み速度が遅くなるため、同様に湯流れが悪くなり、小口径で長尺の製品を鋳造するのは困難であった。   In the above-described conventional centrifugal casting method and casting apparatus, as the cylindrical mold has a small diameter and a long length, it becomes more difficult to flow the molten metal from one end to the other end, and in the middle of the metal There is a problem that solidifies or a sufficient amount of molten metal does not reach the other end. In other words, if the cylindrical mold has a small diameter, the amount of pouring is small, the temperature of the hot water tends to decrease before reaching the tip of the hot water, and the diameter of the discharge port of the pouring device is also small. As a result, the hot water flow similarly deteriorated, and it was difficult to cast a long product with a small diameter.

従って、本発明の目的は、上記問題点を解消し、筒状金型が小口径で長尺になっても十分溶湯が他端部まで供給される遠心力鋳造方法と装置を提供するところにある。   Accordingly, an object of the present invention is to provide a centrifugal force casting method and apparatus in which the above-mentioned problems are solved and a sufficient amount of molten metal is supplied to the other end even when the cylindrical mold has a small diameter and is long. is there.

本発明の遠心力鋳造方法において、第１の特徴構成は、回転軸心周りに回転する筒状金型内にその一端口から注湯装置によって溶湯を加圧して吐出させ、前記筒状金型による遠心力によって、前記溶湯を前記筒状金型内の周面に沿わせながら凝固させる遠心力鋳造方法であって、前記注湯装置の吐出口を前記筒状金型の一端口から挿入して、前記注湯装置の吐出口と前記筒状金型の一端口との間に隙間を設けた状態で、前記吐出口を前記筒状金型内に配置すると共に、前記吐出口から溶湯を吐出すると同時に、気体を前記吐出口の周囲の隙間から前記筒状金型内に流入させて溶湯を流し込むところにある。 In the centrifugal casting method of the present invention, the first characteristic configuration is that the molten metal is pressurized and discharged from a first end of the cylindrical mold rotating around the rotation axis by a pouring device, and the cylindrical mold is discharged. A centrifugal casting method in which the molten metal is solidified along the peripheral surface of the cylindrical mold by centrifugal force generated by inserting a discharge port of the pouring device from one end of the cylindrical mold. In the state where a gap is provided between the discharge port of the pouring device and the one end port of the cylindrical mold, the discharge port is disposed in the cylindrical mold, and the molten metal is supplied from the discharge port. Simultaneously with the discharge, the gas is caused to flow into the cylindrical mold through a gap around the discharge port and the molten metal is poured .

本発明の第１の特徴構成によれば、注湯装置で加圧された溶湯は、吐出口からの吐出流速が上がり、勢い良く筒状金型内に流れ込む。
従って、注湯された溶湯の温度が低下する前に湯先側に流れ、筒状金型が小口径で長尺であっても鋳造を行うことが可能となる。
また、前記吐出口と前記一端口との間の隙間から流入する気体により、その気流に誘導されて吐出口から吐出する溶湯の流速は上がり、湯先側により早く流れ込みやすくなる。従って、小口径であっても長尺の管を鋳造することが可能となる。 According to the first characteristic configuration of the present invention, the molten metal pressurized by the pouring device has a higher discharge flow rate from the discharge port and flows into the cylindrical mold vigorously.
Therefore, before the temperature of the poured molten metal decreases, the molten metal flows toward the hot metal side, and casting can be performed even if the cylindrical mold is small in diameter and long.
Further, the gas flowing in from the gap between the discharge port and the one end port increases the flow rate of the molten metal that is guided by the air flow and is discharged from the discharge port, so that it is easier to flow into the hot water side. Therefore, it is possible to cast a long tube even with a small diameter .

本発明の第２の特徴構成は、前記隙間を覆うように前記筒状金型の一端口の外側に設けた気体吐出ノズルから前記気体を吐出させるところにある。 The second characteristic configuration of the present invention is that the gas is discharged from a gas discharge nozzle provided outside the one end of the cylindrical mold so as to cover the gap .

本発明の第３の特徴構成は、前記吐出口の上側の気体流と下側の気体流の流速に差を付けて、吐出する溶湯に揚力を作用させることにある。 The third characteristic configuration of the present invention, prior SL with a difference in the flow velocity of the upper gas flow and the lower gas flow of the discharge port is to exert a lift on the discharge to the melt.

本発明の第３の特徴構成によれば、前記吐出口と一端口との間の隙間から流入する気体の内、吐出口の上側の気体流と下側の気体流の流速の差により作用する揚力により、吐出口から吐出する溶湯が上方へ浮上り、一端口からより遠くへ飛ばされて供給される。
従って、溶湯が筒状金型内をより早く他端口まで流れ込みやすくなり、全長に亘って行き亘ることになる。 According to the third characteristic configuration of the present invention, the gas flows from the gap between the discharge port and the one end port, and acts by the difference in flow velocity between the gas flow above and below the discharge port. Due to the lift, the molten metal discharged from the discharge port floats upward and is supplied by being blown away from the one end port.
Therefore, it becomes easier for the molten metal to flow into the cylindrical mold faster to the other end and spread over the entire length.

本発明の第４の特徴構成は、前記吐出口の上側の気体流路を、前記吐出口の下側の気体流路よりも長く設定してあるところにある。 The 4th characteristic structure of this invention exists in the place which set the gas flow path above the said discharge outlet longer than the gas flow path below the said discharge opening .
