前に塗布したり鋳造中に連続的に供給したりする。Most of the ingots for rolling, extrusion and forging of non-ferrous metals, especially aluminum and its alloys, are manufactured by a continuous casting method, especially a vertical continuous casting method. One of the methods is so-called DC casting, in which the molten metal is supplied into the upper and lower open molds from the molten metal nozzle above, and the amount of molten metal is controlled by a float type molten metal distributor arranged on the molten metal in the mold. Meanwhile, it is a casting method in which the solidified shell is formed by removing heat from the inner wall of the mold, and the ingot is pulled out while injecting the coolant from the lower part of the mold to completely solidify. At this time, in order to reduce the friction between the mold and the ingot, the lubricant is applied to the inner surface of the mold in advance or continuously supplied during casting.
【０００３】この方法の問題点の一つは、鋳型内溶湯の
表面が大気に接しているため、反応性の強い溶湯の場合
は鋳型内溶湯面において大気中の酸素等と反応し、酸化
物を生成してしまうことにある。生成した酸化物が鋳塊

均一となるため、溶湯が凝固しきれなくなり鋳型の下部
から湯漏れが生じて鋳造が不可能となる。特に非常に反
応性の強いＡｌ−Ｌｉ系合金溶湯では、酸化物の生成が
著しく大気雰囲気での鋳造は不可能である。One of the problems of this method is that since the surface of the molten metal in the mold is in contact with the atmosphere, in the case of a highly reactive molten metal, it reacts with oxygen in the atmosphere on the surface of the molten metal in the mold to form oxides. Is generated. If the produced oxide mixes on the surface of the ingot or inside the ingot, not only will the quality of the ingot be significantly deteriorated, but if the amount of oxide is too large, the ingot will be cooled unevenly and the molten metal will not be able to solidify. Molten metal leaks from the bottom of the mold, making casting impossible. In particular, in the case of an Al-Li alloy melt having a very strong reactivity, the formation of oxides is remarkable, and casting in an air atmosphere is impossible.
【０００４】また他の問題点は、Ａｌ−Ｌｉ系合金溶湯
のような反応性の強い溶湯の場合、潤滑油と溶湯とが反
応し煙を発生することである。煙が発生すると、鋳型内
溶湯面が監視できないため鋳造作業が非常に困難かある
いは全く不可能になる。Another problem is that in the case of a highly reactive melt such as an Al-Li alloy melt, the lubricating oil reacts with the melt to generate smoke. When smoke is generated, the casting operation is very difficult or even impossible because the surface of the molten metal in the mold cannot be monitored.
【０００５】上記２点の問題は単独では解決の可能性が
あるものの、それぞれの解決法が他の問題点をより深刻

く溶湯表面に気流を発生させると、たとえ不活性ガス気
流であろうと大気を巻き込むため、溶湯と大気との接触
効率が高まり、酸化物生成が助長されてしまう。Although the above two problems may be solved by themselves, each solution makes other problems more serious. That is, if a transparent enclosure is provided on the upper part of the mold in order to suppress reaction with the atmosphere and the interior is replaced with an inert gas, the smoke produced cannot be discharged, and the interior cannot be monitored at all. On the contrary, if an air flow is generated on the surface of the molten metal in order to efficiently discharge smoke, the atmosphere will be involved even if it is an inert gas stream, so the efficiency of contact between the molten metal and the atmosphere will be increased, and oxide formation will be promoted. .

連続鋳造方法とその装置を提供することにある。An object of the present invention is to suppress the oxidation reaction by protecting the surface of the molten metal in the mold with an inert gas and to effectively produce smoke produced by the reaction between the lubricating oil and the molten metal. The object of the present invention is to provide a vertical continuous casting method and apparatus capable of monitoring the inside by discharging the material.

In a vertical continuous casting method in which a solidified ingot is drawn downward, the molten metal upper surface is forcibly evacuated and covered with an inert gas that is maintained in a positive pressure state.

有効である。Further, the apparatus of the present invention comprises a cylindrical mold which is opened up and down, a cooling device which injects a cooling agent into a molten metal which is supplied into the mold from above and solidifies the molten metal, and an ingot is moved downward. Atmosphere cover having a cylinder for drawing out and a pit equipped with an exhaust device for accommodating the ingot to be drawn out and exhausting the internal atmosphere, and further having an inlet for inert gas and an exhaust port for covering the upper surface of the molten metal Is provided, and the exhaust port is communicated with the inside of the pit,
At this time, it is effective to form a part of the atmosphere cover with a transparent material.

が監視できるようにする。In order to suppress the oxidation reaction on the surface of the molten metal in the mold, it is necessary to replace the upper surface of the mold with an inert gas. In order to reliably control the atmosphere, it is necessary to further provide a cover on the upper surface of the mold and make the inside thereof an inert gas atmosphere. Part of the cover is made of transparent material so that the inside can be monitored.

うにすればよい。However, the provision of the cover makes it impossible to discharge the generated smoke. Therefore, in order to solve this problem, an inlet and an outlet for the inert gas may be provided in the cover so that the inside of the cover is ventilated by the flow of the inert gas.

鋳塊に割れが発生し、最終的には鋳型下部から凝固しき
れない溶湯が漏れだし、鋳造が不可能になってしまう。However, in order to perform sufficient ventilation, the flow rate of the inert gas also increases, so that the pressure inside the cover rises as the gas flow rate increases. In vertical continuous casting, especially in so-called DC casting, there is always a partial gap between the inner surface of the mold and the ingot, but when the pressure inside the cover, that is, the molten metal surface in the mold increases, the inner surface of the mold and the casting The inert gas flows out to the lower part of the mold through the gap with the lump. When the gas flows out in this way, an inert gas film is unevenly formed in the gap between the coolant injected from the lower end of the mold and the ingot, and the ingot quality deteriorates because the solidification becomes uneven. Moreover, cracks occur in the ingot, and the molten metal that does not solidify finally leaks from the lower part of the mold, making casting impossible.

の低下を生じることになる。Therefore, it is conceivable to enlarge the exhaust port in order to prevent the pressure inside the cover from rising while the flow rate of the inert gas is increased. However, if the exhaust port is enlarged, there is a problem that a backflow of outside air occurs, and further, there is a problem that inertness requires an increase in flow rate. Then, the extreme increase in the flow rate of the inert gas is not only uneconomical, but also causes a decrease in the melt temperature in the mold that must be properly controlled to maintain the quality of the ingot.

めて危険である。Further, as another means for preventing the pressure increase inside the cover, forced exhaust from the exhaust port can be considered. However, in order to keep the pressure inside the cover appropriate and constant, the flow rate balance between the inflowing inert gas amount and the exhaust gas amount must be strictly controlled, which is extremely difficult. That is, if the exhaust amount exceeds the inert gas inflow amount, the inside of the cover becomes negative pressure. In such a case, the coolant penetrates into the upper part of the mold through the gap between the inner surface of the mold and the ingot, and the coolant and the molten metal come into direct contact with each other, possibly causing an explosion, which is extremely dangerous.
【００１４】従ってこれらの問題解決のためには、必要

若干の正圧になるように、不活性ガス流入量と排気量と
のバランスを制御しなくてはならない。Therefore, in order to solve these problems, a balance between the inflow amount of the inert gas and the exhaust amount is ensured so that a necessary positive flow rate of the inert gas is secured and the inside of the cover is stably maintained at a slight positive pressure. Must be controlled.

多量に発生するため、通常ピット内を強制排気する。By the way, in the vertical continuous casting equipment, especially the so-called DC casting equipment, the ingot to be produced is almost always drawn into a pit provided below the mold. In most cases, the coolant used for continuous casting is water or some kind of aqueous solution, and a large amount of water vapor is generated in contact with the high temperature ingot.

ことが可能になり本発明の完成に至った。The present inventors have paid attention to the forced exhaust in the pit. That is, it was found that the exhaust amount can be automatically controlled by introducing the exhaust pipe of the exhaust port provided in the atmosphere control cover into the pit. This is because the inside of the cover communicates with the pit that is forcibly evacuated, so the inside of the cover cannot become a negative pressure than the outside, especially inside the pit below the mold, and the inert gas flows into the cover. Therefore, a slight positive pressure is maintained outside, especially in the pit below the mold. By using the forced exhaust in the pit in this way, while securing the necessary inert gas flow rate,
It has become possible to ventilate the inside of the cover in a stable manner so as to have a slight positive pressure, thus completing the present invention.

Is pulled out into the lower pit (9) by the cylinder (8) together with the base (7).
Further, in order to reduce the friction between the mold and the ingot, a lubricant is applied to the inner surface of the mold in advance or is continuously supplied from the lubricating oil supply port (10) during casting.

The inside is made an inert gas atmosphere to prevent the surface of the molten metal (16) from being oxidized. Also, in order to be able to monitor the inside of the mold,
The upper surface of the cover (11) is a monitoring window (13) made of a transparent material. Further, an exhaust pipe (14) for forced exhaust is provided at the other end of the cover (11) so that smoke generated by the reaction of the lubricating oil and the molten metal is ventilated, and the exhaust pipe (14) is introduced into the pit.

For this reason, the inside of the cover (11) cannot have a negative pressure from the outside, especially from the inside of the pit below the mold (3), and since the inert gas flows into the inside of the cover (11), the outside, especially the mold (3) ) A slight positive pressure is maintained than the lower part. Thus, stable pressure control inside the cover (11) enables reliable atmosphere control and stable maintenance of casting conditions.
