Description
【発明の詳細な説明】 本発明は二層シリンダライナの製造方法に関する。[Detailed description of the invention] The present invention relates to a method of manufacturing a two-layer cylinder liner.
従来ディーゼル機関用シリンダライナの製造力ある。We have the ability to manufacture cylinder liners for conventional diesel engines.
砂型置注ぎ法は、外型及び中子をフラン鋳型またはＣＯ
２鋳型等の砂型で造型し、鋳鉄を鋳造する方法であるが
、中子の表面には炭化物を析出させるために、広範囲に
冷し金を当てる。遠心鋳造法は、金型を高速で回転させ
ながら金型の内面に鋳鉄を鋳造して製作する方法である
。In the sand mold pouring method, the outer mold and core are placed in a Fran mold or a CO2 mold.
In this method, cast iron is cast using a sand mold such as a 2-mold mold, and a cold metal is applied over a wide area to the surface of the core to precipitate carbides. The centrifugal casting method is a manufacturing method in which cast iron is cast onto the inner surface of a mold while rotating the mold at high speed.
上記のものには次の欠点がある。The above has the following drawbacks.
砂型置注ぎ法では２表面に広範囲にしかも多数の冷し金
を当てて、その裏側に砂を搗固めて中子全製作し、別途
製作した砂型の外型と組合せて鋳鉄を鋳造する方法であ
るので、多大の造型工数を要し、シリンダライナが高価
である。In the sand mold pouring method, a large number of cold metals are applied over a wide area on two surfaces, and the sand is pounded and solidified on the back side to make the entire core, which is then combined with the outer mold of a separately manufactured sand mold to cast cast iron. Therefore, a large number of manufacturing steps are required, and the cylinder liner is expensive.
遠心鋳造法では、鋳造した鋳鉄は外側の金型側から凝固
し内面近しが最後に固まる。ところが。In the centrifugal casting method, the cast iron solidifies from the outside of the mold, and solidifies last near the inside. However.
最後に固まる部分には成分偏析や引は巣等が出来るため
、これらを除く必要がち９．肉厚の７０％程度が切削代
になる。このため、鋳造歩留りが小さく、またシリンダ
ライナの最も必要な性質である面ｌ摩粍性を支配する顕
微鏡組織の制御が困難である。9. In the last part that hardens, component segregation and cavities occur, so these tend to need to be removed.9. Approximately 70% of the wall thickness will be the cutting allowance. For this reason, the casting yield is low, and it is difficult to control the microscopic structure that governs surface abrasion, which is the most important property of cylinder liners.
また、上記両刀法によって製作されたシリンダライナは

１一体型で製作されているが、υｊ鉄の強度が低いため

肉厚は７０＋ｎ＋ｎ以上に達しており、軽量化、小形化
が必要である。Furthermore, as shown in Fig. 1, the cylinder liner manufactured by the above-mentioned method is cast iron 0.
However, due to the low strength of υj iron, the wall thickness of cylinder liners for diesel engines for large ships reaches 70+n+n or more, and it is necessary to reduce weight and size.
