く採用されている。[Prior Art] In continuous casting of metals, especially non-ferrous metals such as aluminum and magnesium, a molten metal reservoir is connected to the upstream end of a forced-cooled cylindrical mold, and solidified ingots are continuously cast from the downstream end of the mold. Continuous metal casting equipment equipped with a mechanism for pulling out metal is widely used.

In such a continuous casting apparatus, the ingot 6 is cooled by the wall surface of the cylindrical mold 1 itself and the cooling water discharged from the cooling water flow path 2 formed inside the mold through the injection port 3, and the molten metal 8 is is temporarily held in a molten sump 4 having an overhang 5, and then continuously supplied to a solidification section 7.

グ５直下に導入されている。In continuous casting, in order to prevent seizure between the molten metal or ingot and the mold and to obtain a good ingot casting surface, the inner wall surface of the mold must be kept lubricated. For example, lubricating oil is supplied to the inner wall surface of the mold. things will be done. In addition, a method has been proposed in which gas such as air is introduced directly under the overhang part to improve the casting surface (Japanese Patent Publication No. 54-42847, etc.), and a casting device that adopts a method of supplying air and lubricating oil has been proposed. A conceptual diagram of this is shown in Fig. 6.
It is introduced directly below the overhang 5 through a slit 9 formed between the upper parts of the overhang 5.

Air is supplied from a slit 9 formed between the molten metal reservoir 4 and the mold l, and lubricating oil is supplied from a liquid lubricating oil supply port lO bored on the inner wall surface of the mold.

て気体の出方を不均一にする原因ともなり１作業性や安
定した鋳造を実施する上で問題となっていた。[Problem to be solved by the invention] In vertical continuous casting equipment, when supplying gas or liquid lubricating oil to the inner wall surface of the mold, it is necessary to install slits, grooves, pores, etc. of precise size to match the supply amount. Not only does this complicate the structure of the mold, etc., but it can also cause molten metal to be inserted into slits and pores, or lubricating oil to flow into gas introduction slits, making the flow of gas uneven. This has caused problems in terms of performance and stable casting.

いるため、潤滑油供給用溝に充満した潤滑油は重力のた
め鋳型の下方に集まり、また機械的、エツチング等化学
的方法で設けられた細孔やスリットでは、重力の関係か
ら潤滑油が鋳型下部から集中して流出することとなる。In horizontal continuous casting equipment, the mold is installed horizontally, so the lubricating oil that fills the lubricating oil supply groove collects below the mold due to gravity, and is also supplied mechanically or chemically, such as by etching. In the pores and slits that are formed, the lubricating oil will concentrate and flow out from the bottom of the mold due to gravity.
そのため鋳型下部では潤滑油の供給過多、鋳型上部では
潤滑油の供給不足になり易く、潤滑油流量を最適に調節
することは困難である。Therefore, there tends to be an oversupply of lubricating oil at the lower part of the mold, and an insufficient supply of lubricating oil at the upper part of the mold, making it difficult to optimally adjust the lubricating oil flow rate.

、鋳肌欠陥が生じたり鋳造不能に陥ることがしばしば発
生した。In addition, since openings such as slits and pores are exposed to the molten metal, the hydrostatic pressure of the molten metal forces the molten metal against the mold and inserts it into the opening, which may block the supply port. This often resulted in supply imbalances, resulting in defects in the casting surface and the inability to cast.

In the case of slabs (square ingots) in which the mold is larger than in the case of the mold, the operation is more difficult, and this is the cause of the reluctance to use it for commercial scale production.

する金属の連続鋳造装置である。[Means for Solving the Problems] In order to solve the above-mentioned problems, the present inventors made the gas and/or lubricating oil introduction channels rough, or used fibers made of a material that does not get wet with molten metal. The present invention was completed by configuring the structure by allowing it to pass through. That is, the present invention provides a continuous metal casting apparatus in which a molten metal reservoir is connected to the upstream end of a forced-cooled cylindrical mold, and a mechanism is provided to continuously draw out the solidified ingot from the downstream end of the mold. When supplying gas and/or lubricating oil from between the reservoir and the mold, one or both of the contact surfaces of the molten metal reservoir and the mold that are in contact with each other may be roughened, or this contact surface may be made of a material that is difficult to wet with molten metal. This is a metal continuous casting device characterized by sandwiching non-woven fabric or woven fabric.

溶湯溜の接触面を粗面化しても、あるいはその両者を粗
面化しても良いことは理解できるであろう。In the first invention, it is necessary to roughen one or both of the contact surfaces for the flow path of gas and/or lubricating oil. The contact surface of the mold is made uneven with an average depth of about 20 μm to 200 μm, for example, by shot blasting, or by chemical etching, for example, an average depth of about 20 μm to 300 μm, such as on coarse-grained photographic plates. There are several methods for roughening the surface, such as corrosion, printing with an appropriate number of dots and baking to create minute irregularities on the surface, or mechanical punching to create irregularities. is possible. In short, the flow path for gas and/or lubricating oil is 20μm to 300μm.
It is sufficient that there are countless random paths of about m on the contact surface between the molten metal pool and the mold. Therefore, it can be understood that the surface of the molten metal sump that contacts the mold may be roughened, the surface of the mold that contacts the molten metal sump may be roughened, or both may be roughened.

供給は均一となり、スラブのごとき大型の鋳型において
も鋳造は円滑に行なわれ、供給圧力の上昇もあって金属
溶湯の差し込みによる閉塞も充分に防げることになる。Since the flow paths are extremely narrow and random, and there are an infinite number of them, the resistance is large (thus, the supply to the mold opening is uniform, and casting is smooth even in large molds such as slabs). Since the supply pressure is increased, blockages caused by insertion of molten metal can be sufficiently prevented.
第２の発明は、金属溶湯溜と鋳型の接触面間に溶融金属
に濡れにくい不織布又は織布を挟むことである。The second invention is to sandwich a nonwoven or woven fabric that does not easily get wet with molten metal between the contact surfaces of the molten metal reservoir and the mold.

ることが判った。Inorganic heat-resistant fibers are sandwiched between the molten metal reservoir and the mold.
The concept of supplying gas and/or lubricating oil through this layer has been around for a long time, but if you simply sandwich the fibers and cast them, the fibers will stick to the molten metal during casting, tear off, and get caught up on the surface of the ingot. It was known that molten metal could get inserted into the hole created by tearing off the metal, causing trouble, and was considered impractical. However, when alumina fibers are used in aluminum slab casting, there is no adhesion between the fibers and molten metal, there is no tearing of the fibers, and the supply of gas and/or lubricating oil is smooth, making stable casting possible. It turned out to be.
この場合、繊維層の厚みはＬｍｍ前後であり。In this case, the thickness of the fiber layer is approximately Lmm.
積層した不織布、織布のいずれでもよく、溶融金属に濡

型の大きいスラブの鋳造は平均した潤滑油の供給が容易
であるため、垂直鋳造装置によるのが好ましい。Although the present invention can be applied to a horizontal casting machine, it is preferable to use a vertical casting machine when casting large slabs in a mold because it is easy to supply even lubricating oil.

この結果、従来実施不能と考えられていたスラブの鋳造
