Carbon Steel Seamless Simbi Tube - Royal Boka

1. Kupisa kunotenderedza (extrusion seamless simbi pombi) : round chubhu isina → kudziyisa → perforating → matatu-yakakwirira diagonal rolling, kuramba ichiumburuka kana extrusion → kukurura → saizi (kana kuderedza) → kutonhora → kutwasanudza → hydrostatic test (kana kuongorora) → kumaka → kuchengetedza
Iyo mbishi yekutenderedza isina musono chubhu ndeye yakatenderedza chubhu billet, yakatenderedza chubhu embryo inochekwa uye inogadziriswa nemuchina wekucheka nekukura kwemamita 1 isina chinhu, uye inotumirwa kuchoto nekudziya kwebhandi rekutakura. Iyo billet inoiswa muchoto uye inopisa kusvika ku1200 degrees Celsius. Iyo mafuta ndeye hydrogen kana acetylene. Kudzora tembiricha muchoto ndiro dambudziko guru. Mushure mekunge iyo round tube billet yabuda, inoputirwa nekumanikidza punch. Kazhinji, iyo inonyanya kuzivikanwa perforator ndiyo conical roll perforator. Rudzi urwu rweperforator rune hunyanzvi hwekugadzira, kunaka kwechigadzirwa, hombe perforating dhayamita uye inogona kupfeka akasiyana simbi. Mushure mekuputika, iyo denderedzwa chubhu billet inotenderedzwa zvakatevedzana nematatu akakwirira diagonal, inoenderera ichikunguruka kana extrusion. Mushure me extrusion, pombi inofanira kubviswa kuti isangwe. Iyo caliper inotenderera ichipinda musimbi embryo kuburikidza nechibooreso checonical chirikumhanya kwazvo kubaya maburi uye kugadzira mapaipi esimbi. Iyo dhayamita yemukati yepombi yesimbi inotarirwa nekunze kwedhayamita kureba kweiyo caliper drill bit. Mushure mekuyera pombi yesimbi, inopinda mushongwe yekutonhora uye inotonhodzwa nekumwaya mvura. Mushure mekutonhodza pombi yesimbi, ichagadziriswa.
2. Pombi yesimbi inotonhorwa (yakakungurutswa) isina musono: chubhu yeround isina → kudziyisa → perforation → musoro → annealing → pickling → kuzora (copper plating) → yakawanda-ipfuura inotonhora kudhirowa (inotonhora inomonereka) → isina chinhu chubhu → kupisa kupisa → kutwasanura → hydrostatic bvunzo (kuongorora) → kucherekedza
Iyo nzira yekutenderedza yekudhirowa inotonhora (kukunguruka) isina musono pombi yesimbi yakaoma kupfuura iyo inopisa inopisa (extrusion) isina musono pombi yesimbi. Matanho matatu ekutanga ekugadzira kwavo maitiro akafanana. Musiyano kubva pachinhanho chechina, kutenderera chubhu isina chinhu mushure mekurova, kuenda kumusoro, annealing. Mushure mekuvhara, yakakosha acidic fluid inoshandiswa pakunhonga. Mushure mekutora, mafuta anoiswa. Izvi zvinoteverwa nekupisa kwakakosha kurapwa kwechubhu rebillet mushure mekudhirowa kwakawanda kunotonhora (kutonhora kukunguruka). Mushure mekurapa kwekupisa, inoruramiswa.
