【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、主として化学プラント用装置及び原子力用放
射性溶解液槽等に使用されるジルコニウムなどの難溶接
性金属製容器に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a non-weldable metal container made of zirconium or the like, which is mainly used in a chemical plant device, a nuclear radioactive solution tank, and the like.
近年、放射性溶解槽用等に使用される金属製容器には、
容器の内外で大きな温度差があると共に、その容器内に
静水圧がかかるので、容器本体の変形の恐れがある。In recent years, metal containers used for radioactive melting tanks, etc.
Since there is a large temperature difference between the inside and outside of the container and hydrostatic pressure is applied inside the container, the container body may be deformed.
また、この種の容器はその安全性保持などのため高度な
耐食性が要求されるため、ステンレス鋼では不充分であ
り、従来一般にはジルコニウム製容器が用いられている
が、このようなジルコニウムはチタニュウム合金等と同
様にもろい性質を有し、溶接が難かしく、特に他の金属
との溶接は非常に困難であるという問題がある。Further, this type of container requires a high degree of corrosion resistance in order to maintain its safety, etc., so that stainless steel is not sufficient, and conventionally zirconium containers have been generally used. Similar to alloys and the like, it has brittle properties and is difficult to weld. In particular, welding with other metals is very difficult.
そこで、第6図の側面図、第7図の平面図及び第8図の
要部側断面図に示すごとき従来の角型容器においては、
その容器の胴板材1の外周に、平板の補強リブ材2を梯
子状に設けて容器の変形防止用の補強を行なっている。Therefore, in the conventional rectangular container as shown in the side view of FIG. 6, the plan view of FIG. 7 and the side sectional view of the main part of FIG.
A flat plate reinforcing rib member 2 is provided in a ladder shape on the outer periphery of the body plate member 1 of the container to reinforce the container for preventing deformation of the container.
しかしながら、これら補強リブ材2を第8図のごとくス
ミ肉溶接3で容器の胴板材1に取付けているため、その
溶接性の信頼性が劣るという問題がある。However, since these reinforcing rib members 2 are attached to the body plate member 1 of the container by fillet welding 3 as shown in FIG. 8, there is a problem that the reliability of the weldability is poor.
また、補強リブ材2の板厚部を溶接する際、不活性ガス
等によるガスシールが充分に行き渡り難いため、酸化に
よるぜい化が生じ、この部分に応力が集中し、特に疲労
強度の低下をもたらすという問題がある。Further, when welding the thick portion of the reinforcing rib material 2, it is difficult to sufficiently spread the gas seal with an inert gas or the like, so that embrittlement due to oxidation occurs, stress concentrates on this portion, and fatigue strength particularly decreases. There is a problem of bringing.
さらに、スミ肉溶接3部分は、液浸透探傷試験のみが可
能で、X線による非破壊検査ができず、信頼性にとぼし
いという問題があった。Further, the 3 parts of the fillet weld can only be subjected to a liquid penetrant flaw detection test and cannot be subjected to a nondestructive inspection by X-rays, resulting in poor reliability.
本考案は、前記従来の問題点を解決するためになされた
ものであり、難溶接性金属製容器でありながら、溶接部
のX線による非破壊検査や液浸透探傷試験が可能である
ため、容器の信頼性が高く、更に、コスト低減を計り得
る溶接性金属製容器を提供することにある。The present invention has been made in order to solve the above-mentioned conventional problems, and because it is a non-weldable metal container, it is possible to perform non-destructive inspection by X-ray of a welded portion and liquid penetrant flaw detection test. An object of the present invention is to provide a weldable metal container which has a high container reliability and can reduce the cost.
上記の課題を解決するための手段として、本考案の難溶

補強リブ材に炭素鋼やステンレス鋼等の低級鋼からなる
補強部材をボルトにより取り付けて成ることを特徴とす
るものである。As a means for solving the above problems, the hardly-weldable metal container of the present invention comprises a reinforcing rib material surrounding the entire circumference of the hardly-weldable metal container, and a container shell plate material of the same quality as the reinforcing rib material. A container is formed by joining by butt welding on both sides, and a reinforcing member made of a low grade steel such as carbon steel or stainless steel is attached to the reinforcing rib material with a bolt.
以下図面を参照して本考案の実施例を説明するが、各実
施例においてそれぞれ同じ部品は同じ部品番号で示して
いる。Embodiments of the present invention will be described below with reference to the drawings, in which the same parts are denoted by the same part numbers.
まず、第1図は本考案の実施例1における難溶接性金属
製容器の要部側断面図、第2図は第1図の側面図、第3
図は第2図の平面図である。First, FIG. 1 is a side sectional view of a main part of a hardly weldable metal container in Embodiment 1 of the present invention, FIG. 2 is a side view of FIG. 1, and FIG.
The figure is a plan view of FIG.
この容器は、ジルコニウム製のものであり、その全周を
囲む補強リブ材2と、この容器の胴板材1とが同一材質
のジルコニウムで形成されており、これらが両側突合せ
溶接5で接合されている。This container is made of zirconium, and the reinforcing rib material 2 that surrounds the entire circumference of the container and the body plate material 1 of the container are made of zirconium, which is the same material, and these are joined by butt welding 5 on both sides. There is.
また、この補強リブ材2は鍛造材または厚板材から作製
されており、第1図に示すように適宜なR加工が施され
ており、両側突合せ溶接5部分もこのR加工部から離れ
ているため応力の集中がなく、疲労強度の向上がはかれ
る。The reinforcing rib material 2 is made of a forged material or a thick plate material, and is appropriately R-processed as shown in FIG. 1, and the both-sides butt welding 5 portion is also separated from this R-processing portion. Therefore, stress is not concentrated and fatigue strength is improved.
なお、この実施例1では、上記の複数の補強リブ材2の
間に、縦方向の補強部材6を取付けている。In the first embodiment, the vertical reinforcing member 6 is attached between the plurality of reinforcing rib members 2.
次に、第4図の要部側断面図に示す実施例2の金属製容

いる。Next, since the metal container of Example 2 shown in the side sectional view of the main part of FIG. 4 has substantially the same structure as that of Example 1, the reinforcing rib material 2 made of zirconium similar to that of FIG. 1 is used. An L-shaped or H-shaped reinforcing member 7 is attached to the rib portion of with a bolt 8.

で取付けている。Since zirconium is an expensive metal material, a relatively inexpensive reinforcing member 7 such as carbon steel or stainless steel is used to reduce the material of the reinforcing rib material 2 made of zirconium as much as possible to make an inexpensive container. This is because the zirconium is supplied, and since it is very difficult to weld zirconium to other foreign metals, the reinforcing member 7 is attached by tightening the bolt 8.
さらに、第5図の要部側断面図に示す実施例3は実施例

By using a ring-shaped plate made of aluminum, the amount of material used for the expensive reinforcing rib material 2 of zirconium is minimized, and the reinforcing ring 9 made of carbon steel, stainless steel or the like has the function of the reinforcing support structure, and thus an inexpensive container. It is what

補強リング9及び補強リブ10を補強部材としている。Also in this third embodiment, the reinforcing ring 9 is attached to the reinforcing rib member 2 with the bolt 8, and the inexpensive reinforcing rib 10 such as carbon steel or stainless steel is attached to the reinforcing ring 9 in the vertical direction. The reinforcing rib 10 is used as a reinforcing member.
