摘要: 介紹了雙相不銹鋼轉(zhuǎn)鼓用管的離心鑄造生產(chǎn)工藝，并與傳統(tǒng)的卷制焊接成型轉(zhuǎn)鼓生產(chǎn)工藝進(jìn)行了對(duì)比，離心鑄造優(yōu)勢(shì)明顯。對(duì)采用該工藝生產(chǎn)雙相不銹鋼轉(zhuǎn)鼓的生產(chǎn)實(shí)踐作了詳細(xì)介紹，包括材料成分、鑄型轉(zhuǎn)速及熱處理工藝的確定等。經(jīng)檢測(cè)，生產(chǎn)的雙相不銹鋼轉(zhuǎn)鼓致密度高，氣孔、夾渣等缺陷少，機(jī)械性能好，可滿足特殊應(yīng)用環(huán)境對(duì)轉(zhuǎn)鼓無縫化制造的要求。Abstract: Elaborated in the article is the centrifugal casting process for manufacturing dual phase stainless steel tube for drum-making. Compared to the conventional coiling-welding process for the same purpose，the centrifugal casting process has obvious advantages. Relevant operational practice of producing the dual phase stainless steel tube for drum-making with the said centrifugal casting process is also detailed， involving such aspects as material chemical composition，casting speed and determination of the heat treatment process， etc. The results of relevant tests and inspections show that the drum fabricated with the dual phase stainless steel tube as produced with the above mentioned centrifugal casting mould RPM is in possession of such advantages as high density，very few defects like gas hole，trapped-slag and fine mechanical properties，being satisfactory to the requirement for manufacturing the seamless drum which is suitable for special service conditions.
