Hombe-diameter isina musono pombiThermal molding kugadzira nzira

Thermal kuumba nzira yekugadzira, kusanganisira yakakura-dhayamita isina musono inopisa-yakakungurutswa uye inopisa extrusion yenzira mbiri, yekutanga inonyanya kushandiswa mukugadzira composite pombi majoini, iyo inoshanda isina musono composite pombi kugadzirwa.

Rolling inzira yechinyakare yekugadzira hombe-diameter isina musono pombi yesimbi.Kupisa kukungurutsira muchinhu kudzvanywa kwewelding, kana deformation yakakura zvakakwana, kudzvanywa kunoitwa nemupumburu wesimbi kunokuvadza pamusoro peiyo oxide firimu, iyo atomu yepamusoro inosangana, kuitira kuti nzvimbo mbiri idzi dzibatanidzwe pamwechete.Rolling yakashata ndeye:

Zvakanakira kutenderedza: kugadzirwa kwepamusoro, hunhu hwakanaka, mutengo wakaderera, uye unogona kuchengetedza kwakawanda kupfeka uye kubvaruka kwezvinhu zvesimbi, uye nekudaro yakanyanya kupararira kushandiswa kwekombiji yekugadzira zvinhu tekinoroji.Kutenderedza pepa rinobatanidza 90% yeiyo yakazara composite ndiro, uye inowanzoiswa kune pombi madziro ukobvu isingasviki 32mm yekugadziriswa.

Kuipa kwekukunguruka: imwe-nguva yekudyara, asi zvakare yakawanda yekusanganiswa kwezvinhu haigone kuwanikwa nekukunguruka kwakaoma.Parizvino ndiyo inonyanya kushandiswa tekinoroji yekushandiswa kwesimbi inomonereka, simbi isina tsvina inoumba pombi majoini ekugadzira.

Kupisa extrusion kunowanzo kuitirwa iyo bi-simbi chubhu, inonzi composite extrusion (coextrude).Coextrusion parizvino ndiyo yakanakisa nzira yekugadzira simbi isina tsvina uye yakakwirira nickel alloy isina musono composite chubhu, Japan Steel inogadzirwa neiyi nzira 8in (203.2mm) pazasi bimetallic composite pombi.Iyo yakakura-dhayamita inoumbwa ine maviri kana anopfuura simbi isina blank inodziya kusvika 1200.℃, uyezve yakawedzera kuburikidza ne annular space yakagadzirwa ne mold uye mandrel.Kana extrusion billet cross-section yakaderedzwa kusvika 10: 1, high extrusion pressure uye tembiricha pane iyo interface inogadzirwa "pressure welding" welding effect, inosimudzira kukurumidza uye kwakapararira kupararira kweiyo interface pakati pemubatanidzwa kuti uwane metallurgical bonding interface.Pamberi pe extrusion composite chubhu yekugadzira nzira, kune matatu: iyo yekubira billet kuboora uye yakawedzerwa nekupisa extrusion yakawanikwa;yakananga centrifugal spin kukanda;zvimedu zvehupfu zvinodzivirira ngura.Kune maviri masimbi emagetsi anoshandiswa mukati nekunze kwehupfu, inonzi "NUVAL" tekinoroji, inogona kugadzira alloys matsva, asi mutengo wakanyanya wekugadzira hupfu.Coextrusion zvakaipa ndezvi:

Zvakanakira kupisa extrusion : The interface is metallurgically bonded;mauto anobatanidzwa muextrusion process ndeyekushushikana zvachose, inonyanya kukodzera kune inopisa workability, yakakwirira alloy processing yakaderera plasticity yesimbi.

Zvakashata zvekupisa extrusion: Sezvinotsanangurwa neiyo extrusion process yakasanganiswa nepfupi pfupi diffusion interface zvinhu, kazhinji nekuda kwekuvapo kwemaokisisa mafirimu akakanganiswa, kusvika parizvino akaganhurirwa kune composite extrusion composite kabhoni simbi, Stainless simbi uye yakakwirira nickel alloys pakati. .Zvinocherechedzwa kuti diki deformation kuramba kweanopisa extrusion, achibvumira yakakura deformation yeimwe neimwe, zvichikonzera yakakwirira pamusoro roughness, uye saka zvakare kutonhora kukungurutsa inopisa extrusion (kana kudhirowa) nzira yekugadzira inoumbwa pombi. .
