1. Kupisa yakakungurutswa seamless simbi pombi
Kupisa (Hot rolling) kunoreva kupisa billet resimbi kusvika patembiricha yakakodzera uye kugadzira pombi yesimbi isina musono kuburikidza nekukanda nekukunguruka. Kupisa-yakaputirwa seamless simbi pombi ine hunhu hwekusimba kwepamusoro, yakanaka plasticity uye welding performance nekuda kwekukwana kwepurasitiki deformation yezviyo mukati mepombi yesimbi mushure memaitiro akawanda ekukungurutsa. Panyaya yemamiriro ekutumira, hot-yakakungurutswa seamless simbi mapaipi akakamurwa kuita matunhu matatu: dema ganda, ganda rakatsetseka uye ganda rekukuya. Ganda dema ndiyo nyika isina kurapwa kwepamusoro, ganda rakatsetseka ndiyo nyika mushure mekurapwa kwepamusoro, uye ganda rekukuya ndiyo nyika. High tembiricha polished state.
2. Kupisa-kurapwa seamless simbi pombi
Kupisa kupisa kwepombi isina musono pombi kunoreva kudziyisa, kuvharisa uye kutonhodza kwepombi isina musono yesimbi kuitira kuti ive nezvimwe zvemichina uye zvemuviri. Mamiriro ekutumira mapombi esimbi asina musono anobatwa nekupisa anowanzo kuvharwa kana kujaira. Kudziisa (annealing state) zvinoreva kudziyisa pombi yesimbi kune imwe tembiricha, kuibata kwenguva yakati rebei, yozoitonhodza zvishoma nezvishoma kusvika mutembiricha yekamuri; the normalizing state inoreva kudziyisa pombi yesimbi kune imwe tembiricha, ichiibata kwenguva yakati kuti, yozoitonhodza nemvura kana kuitonhodza mafuta kuti ive nesimba rakakwirira nekuoma.
3. Musiyano pakati pekupisa-akakunguruswa uye kupisa-kugadziriswa seamless simbi mapaipi
Kupisa kutenderedza uye kurapwa kwekupisa maitiro maviri akasiyana mukugadzirwa kwemapombi esimbi asina musono, uye mamiriro ekutumira anewo mimwe misiyano. Hot-yakakungurutswa seamless simbi pombi ine yakanaka plasticity, welding performance uye yakakwirira simba, uye inokodzera kumwe kumanikidza kupikisa, kupisa kupisa, corrosion resistance uye mamwe minda. Mapombi esimbi asina musono anopisa ane kuomarara kwepamusoro, simba uye zvimwe zvinhu zvemuchina mushure mekuvhara kana kuti normalizing kurapwa, uye akakodzera minda yeinjiniya inoda kushingirira zvakanyanya uye mitoro inorema.
Muchidimbu, pakusarudza mapaipi esimbi asina musono, kusarudzwa kunofanirwa kuve kwakavakirwa pazvido zvekushandisa chaizvo uye mamiriro ekutumira mapaipi asina musono. Panguva imwecheteyo, teerera kutenga zvigadzirwa zvinogadzirwa nevagadziri venguva dzose kuti uve nechokwadi chekuti kunaka kwavo uye kuita kwavo zvinosangana nezvinodiwa.
