Description

【発明の詳細な説明】 厚さ１０ｍｍ以下の金属ストリップの 製造方法および製造プラント 長さが無限の薄い金属ストリップは、冷却ローラ上に棒（バー）またはストリッ プをキャスティングすることによって製造することができる。[Detailed description of the invention] of metal strips with a thickness of 10 mm or less Manufacturing method and manufacturing plant Thin metal strips of infinite length are placed on cooling rollers in bars or strips. It can be manufactured by casting.

この型の製造方法では、ストリップが不均質な組織（または構造）を有するもの になることがわかっていた。特に、多相凝固組織を有する合金の場合には、バー の端部領域から中心部へ延びる樹枝状結晶が形成される。このような望ましくな い組織の形成は、続いて実施されるローリングだけで取り除くことができない、 従って、従来は、キャスティングの後でストリップをエージングさせ、そして別 の工程でそれに組織改善処理を施すことが行われている。In this type of manufacturing method, the strip has a non-uniform texture (or structure). I knew it would be. In particular, in the case of alloys with multiphase solidification structures, bar Dendrites are formed extending from the end regions to the center. This kind of undesirable The formation of ugly tissue cannot be removed by subsequent rolling alone; Conventionally, therefore, the strip is aged after casting and then In the step of this process, a tissue improvement treatment is performed on it.

望ましい最終的な厚みのストリップよりも厚いストリップをロール処理し、望ま しい最終的な厚みにすることを、キャスティングと同じ１ライン内で行うことも 知られている。このローリングの費用はかなりなものになる。Roll a strip thicker than the desired final thickness of the strip to achieve the desired final thickness. Achieving the desired final thickness can also be done within the same line as casting. Are known. The cost of this rolling can be considerable.

最後に、ストリップキャスティングにおいて不均質組織が形成されることもわか った。従って、偏析の均一化が必要である。Finally, it was also found that a heterogeneous structure is formed in strip casting. It was. Therefore, it is necessary to equalize the segregation.

本発明は、微粒化または均質化組織を有する金属ストリップを連続的に製造する ことができる方法を提供する目的に基づくものである。また、本発明は、この目 的に適したプラントを提供する目的に基づくものでもある。The present invention continuously produces metal strips with atomized or homogenized textures. It is based on the purpose of providing a method that can be used. In addition, the present invention It is also based on the purpose of providing a plant that is suitable for various purposes.

本発明は、厚さ１０ｍｍ以下の金属ストリップの製造方法に基づくものである。The invention is based on a method for manufacturing metal strips with a thickness of 10 mm or less.

この方法では、溶融金属をキャスティングしてストリップを生成し、そして１つ の連続ライン上で、そのストリップに塑性変形および加熱処理を施し、続いて冷 却区画を通過させる０本発明方法においては、ストリップを最終的な寸法に近い 厚さにキャスティングし、このストリップの塑性変形は、高温下およびほとんど 厚みの減少に実施する。In this method, molten metal is cast to produce a strip, and one On a continuous line, the strip is subjected to plastic deformation and heat treatment, followed by cooling. In the method of the present invention, the strip is passed through a cooling section close to its final dimensions. The plastic deformation of this strip when cast to a thickness can be done under high temperature and almost Performed to reduce thickness.

本発明の一態様によれば、塑性変形が行われる温度は、次に行われるアニーリン グ処理の温度よりも低いものである。あるいは、塑性変形をアニーリング処理と 同時に実施することもできる。アニーリング処理はシール用ガス雰囲気下で実施 するのが好ましい、アニーリング処理を塑性変形と同時に実施せず、従って低い 温度で実施する場合であっても、塑性変形をシール用ガス雰囲気下で実施するの が好ましい。According to one aspect of the invention, the temperature at which the plastic deformation is performed is determined by the temperature at which the subsequent annealing is performed. The temperature is lower than the temperature of the cleaning process. Alternatively, plastic deformation can be combined with annealing treatment. They can also be performed simultaneously. Annealing treatment is performed under a sealing gas atmosphere It is preferable to carry out the annealing treatment at the same time as the plastic deformation and therefore reduce the Even if the plastic deformation is carried out at high temperatures, it is difficult to carry out the plastic deformation under a sealing gas atmosphere. is preferred.

ストリップの実質的な厚み低下を伴わない塑性変形は、ストリップ平面に平行で 、ストリップの流れ方向に垂直な軸に関してストリップを繰り返し曲げることに よって行うのが好ましい。Plastic deformation without substantial thickness reduction of the strip is parallel to the strip plane. , by repeatedly bending the strip about an axis perpendicular to the direction of strip flow. Therefore, it is preferable to do so.

本発明は、厚さ１０ｍｍ以下の金属ストリップの製造プラントにも関する０本発 明のプラントは、１ラインに配列されたプラント区画からなる。即ち、ストリッ プ−キャスティング装置、加熱処理区画および／または温度均一化区画、ストリ ップを塑性的に変形する変形単位、およびラインの端部に位置する冷却区画であ る０本発明の前記プラントにおいて、前記の変形単位は、牽引矯正化（ｓｔｒａ ｉｇｈｔｅｎｉｎｇ）装置の態様でストリップを折り曲げて通過させるために設 けられている。本発明の態様によれば、熱均−化区画を変形単位の前に配置する −のが好ましい、加熱処理区画をアニーリング用に配置する場合には、変形単位 と一体にするか、あるいはその後に配置する。The present invention also relates to a manufacturing plant for metal strips with a thickness of 10 mm or less. A light plant consists of plant sections arranged in one line. That is, strip Pour casting equipment, heat treatment section and/or temperature equalization section, strip a deformation unit that plastically deforms the pipe, and a cooling section located at the end of the line. 0 In the plant of the present invention, the deformation unit has traction straightening (straightening). (lightening) device designed for folding and passing the strip. I'm being kicked. According to an aspect of the invention, a heat equalization section is placed in front of the deformation unit. − is preferred, when the heat treatment zone is arranged for annealing, the deformation unit be integrated with or placed after it.

個々のプラント区画における必須の処理をできるかぎり最良の態様で実施するた めに、プラント区画を熱的に相互に分離するのが好ましい。In order to carry out the essential treatments in the individual plant sections in the best possible manner. For this reason, it is preferable to thermally separate the plant sections from each other.

熱均−化区画および加熱処理区画においてストリップが調整されるべき温度は、 ストリップ材料に依存し、そして、ストリップに再結晶アニーリングを施すべき か否か、またはストリップを組織均質化のためにアニーリングすべきか否かに依 存する。The temperature to which the strip should be adjusted in the heat equalization section and the heat treatment section is: Depends on the strip material and the strip should be subjected to recrystallization annealing or whether the strips should be annealed for tissue homogenization. Exists.

例えば、スチール中において微粒化組織が望ましい場合には、７００〜１０００ ℃の温度範囲が再結晶アニーリングに好ましいことが分かった。しかしながら、 組織均質化のためのアニーリングの場合には、１０００°Ｃよりも高い温度でア ニーリングを実施するのが好ましい。For example, if a fine grained structure is desired in steel, 700 to 1000 A temperature range of 0.degree. C. was found to be favorable for recrystallization annealing. however, In the case of annealing for tissue homogenization, annealing is performed at a temperature higher than 1000°C. Preferably, kneeling is performed.

本発明を添付図面に沿って、以下に詳細に説明する。添付図面は２種のプラント を模式的に示す側面図であり、これらのプラントによって、２種の別々の方法を 実施することができる。The present invention will be described in detail below with reference to the accompanying drawings. The attached drawings show two types of plants. This is a side view schematically showing two different methods using these plants. It can be implemented.

溶融金属を充填したキャスティング容器１から、調節可能なギャプ幅を有する出 ロギャプを通して、回転冷却ホイール２の滑らかで冷却されたシェル表面に溶融 金属を与える。シェル表面上で凝固するストリップ３の厚みは、冷却ホイール２ の運転速度および出口ギャップの幅を調整することにより、厚さ１０ｍｍ以下に 調整することができる。ストリップ３は、ループを形成しながら、最初のローラ 一対４の領域中を通過する。出口ギャップを有するキャスティング容器１、冷却 ホイール２およびローラ一対４は、外部雰囲気から分離され、シール用ガスで充 填された部屋５の中に収容されている。From a casting container 1 filled with molten metal, an outlet with an adjustable gap width is Melt through the log gap onto the smooth and cooled shell surface of the rotating cooling wheel 2 Give metal. The thickness of the strip 3 that solidifies on the shell surface is determined by the thickness of the cooling wheel 2 By adjusting the operating speed and the width of the exit gap, the thickness can be reduced to 10 mm or less. Can be adjusted. Strip 3 passes through the first roller while forming a loop. Pass through the 1:4 area. Casting container 1 with outlet gap, cooling Wheel 2 and roller pair 4 are isolated from the outside atmosphere and filled with sealing gas. It is housed in a room 5 filled with

キャスティング装置１および２を備えた部屋５と１つのラインで、更に部屋６、 部屋７および部屋８が配置されており、それらは外部雰囲気から分離され、それ らの中でストリップ材料に種々の処理が施される０部屋６と部屋７の順番は、２ つの例示において異なっている。In one line with room 5 with casting devices 1 and 2, furthermore room 6, Room 7 and Room 8 are arranged, which are separated from the external atmosphere and The order of rooms 6 and 7, where various treatments are applied to the strip material, is 2. The two examples are different.

図１に示した例において、ストリップ材料は部屋６において成る温度にされるが 、その温度はそのストリップ材料に依存し、しかも続く部屋７での塑性変形に好 ましい温度である０部屋７で、ストリップ３は、ブレーキローラ対１．０と牽引 ローラ対１１との間に配置されたローラ９の上を曲がりくねって通過し、このな めに塑性的に変形される。ストリップ３のこの型の処理は、牽引矯正化装置にお けるストリップの処理に相当する。この塑性変形に関連して、再結晶アニーリン グを行うことができるが、これはシール用ガスの雰囲気中で実施するのが好まし い。In the example shown in FIG. 1, the strip material is brought to a temperature of , whose temperature depends on the strip material and favors the subsequent plastic deformation in chamber 7. In room 7, which is at the desired temperature, the strip 3 is in traction with the brake roller pair 1.0. It winds over the roller 9 disposed between the roller pair 11 and plastically deformed. This type of treatment of strip 3 is carried out in a traction straightening device. This corresponds to the treatment of strips that Related to this plastic deformation, recrystallization annealing This is preferably done in a sealing gas atmosphere. stomach.

次の部屋８の中で、予め定めたプログラムに従って、ストリップを冷却する。In the next chamber 8 the strip is cooled according to a predetermined program.

図２に示した例においては、部屋５におけるストリップのキャスティングの直後 に、同じ部屋７で処理を行う、しかしながら、この場合には、塑性変形が再結晶 アニーリングと組み合わされず、それよりはむしろ、部屋７の温度を塑性変形に 好ましい温度に調整する。しかしながら、ここでも、シール用ガス雰囲気下で、 処理を行うのが好ましい０部屋６の再結晶アニーリング（好ましくはシール用ガ ス雰囲気下で行う）は、この塑性変形の後でのみ行う。続いて、ストリップ材料 に依存するプログラムに従って、部屋８にて冷却を行う。In the example shown in Figure 2, immediately after the casting of the strip in room 5 In this case, however, the plastic deformation is recrystallized. It is not combined with annealing, but rather the temperature in room 7 leads to plastic deformation. Adjust to desired temperature. However, here too, under the sealing gas atmosphere, 0 chamber 6 recrystallization annealing (preferably sealing gas) (carried out under a gas atmosphere) is carried out only after this plastic deformation. Next, strip material Cooling is carried out in room 8 according to a program depending on.

本発明が従来技術と異なっている点は、キャスティングによって製造されたスト リップを連続的に処理して、従来法によって製造されたストリップとは異なり、 処理温度に依存してその全断面積にわたって微粒化または均質化組織を有してい るストリップが処理の終点で得られる点である。The present invention differs from the prior art in that the string manufactured by casting Unlike strips manufactured by conventional methods, the lip is processed continuously. It has an atomized or homogenized structure over its entire cross-sectional area depending on the processing temperature. This is the point obtained at the end of the process.
