Structural seamless pombi (GB/T8162-2008) imhando yesimbi isina musono pombi inoshandiswa kune yakajairwa dhizaini uye mechaniki chimiro. Iyo fluid seamless simbi pombi mwero inoshanda kune isina musono pombi dzesimbi dzinotakura zvinwiwa.

Kuwedzera kune kabhoni (C) zvinhu uye imwe chiyero chesilicon (Si) (kazhinji haipfuure 0.40%) uye manganese (Mn) (kazhinji haipfuure 0.80%, yakakwirira kusvika 1.20%) alloy zvinhu zve deoxidation, structural. simbi mapaipi , pasina mamwe alloying elements (kunze kwezvakasara zvinhu).

Mapombi esimbi akadaro anofanirwa kuvimbisa zvese zvemakemikari kuumbwa uye zvemuchina. Zviri mukati mesarufa (S) uye phosphorus (P) zvinhu zvisina kuchena zvinowanzodzorwa pazasi 0.035%. Kana ichidzorwa pasi pe 0.030%, inonzi high-grade high-quality steel, uye "A" inofanira kuwedzerwa mushure megiredhi yayo, yakadai se20A; kana P ichidzorwa pazasi 0.025% uye S iri pazasi 0.020%, inodaidzwa kuti super-quality structural steel pipe, uye giredhi rayo rinofanira kuteverwa neAdd “E” kusiyanisa. Kune zvimwe zvakasara zvealloying zvinhu zvinounzwa mumapombi esimbi kubva kune yakabikwa, zviri mukati mechromium (Cr), nickel (Ni), mhangura (Cu), nezvimwe zvinowanzodzorwa paCr≤0.25%, Ni≤0.30%, Cu≤ 0.25%. Mamwe magiredhi emanganese (Mn) zvemukati anosvika 1.40%, anonzi manganese simbi.

Musiyano uripo pakati pekuumbwa seamless pombi uye fluid seamless pombi:

Musiyano mukuru uripo pakati payo uye yekuumbwa isina musono simbi pombi ndeyekuti fluid isina musono simbi pombi inoiswa hydraulic bvunzo imwe neimwe kana ultrasonic, eddy ikozvino uye magineti flux leakage yekuongorora. Naizvozvo, mune yakajairwa sarudzo yekumanikidza pombi simbi mapaipi, mvura isina musono pombi haifanirwe kushandiswa. Iyo inomiririra nzira yesimbi isina musono pombi ndeyekunze dhayamita, ukobvu hwemadziro, uye gobvu-yakakomberedzwa seamless simbi pombi inonyanya kushandiswa kugadzira, mugodhi wemarasha, hydraulic simbi, uye zvimwe zvinangwa. Zvinhu zvepombi yesimbi isina musono yakakamurwa kuita 10#, 20#, 35#, 45#, 16Mn, 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo zvichingodaro.

Chimiro chesimbi isina musono pombi (GB/T14975-1994) inopisa-yakakungurutswa (yakasimudzwa, yekuwedzera) uye inotonhora inodhonzwa (yakakungurutswa) isina musono pombi dzesimbi.

Nekuda kwemaitiro adzo akasiyana ekugadzira, pombi dzesimbi dzisina musono dzakakamurwa kuita mapaipi esimbi anopisa-akakungurutswa (akaburitswa) asina musono nemapombi esimbi anotonhora (akakungurutswa) asina musono. Cold yakadhonzwa (yakakungurutswa) machubhu akakamurwa kuva marudzi maviri: akatenderera machubhu uye akakosha-akaumbwa machubhu.

Process flow overview:
Kupisa kutenderedza (yakawedzera simbi isina musono pombi): yakatenderedza chubhu billet → kudziyisa → perforation → matatu-roller skew rolling, inoenderera ichikunguruka kana extrusion → kubviswa kwechubhu → saizi (kana kuderedzwa kwedhayamita) → kutonhora → billet chubhu → kutwasanudza → mvura yekumanikidza Muedzo (kana kuona kukanganisa) → maka → kuchengetedza.

Inotonhora inodhonzwa (yakakungurutswa) isina musono pombi yesimbi: round chubhu billet → kudziyisa → perforation → musoro → annealing → pickling → kuzora (copper plating) → yakawanda-pass inotonhora kudhirowa (inotonhora kukunguruka) → billet → kupisa kupisa → kutwasanura → Hydraulic test (kukanganisa kuona)→maka→kuchengetera zvinhu.
