Zvichienderana nenzira yekugadzira, mapaipi esimbi anogona kukamurwa kuita mapoka maviri: mapaipi esimbi asina musono uye mapaipi esimbi akasungirirwa. Pakati pawo, mapaipi esimbi eERW ndiwo mhando huru yemapaipi esimbi akasungirirwa. Nhasi, tinonyanya kutaura nezvemhando mbiri dzemapaipi esimbi anoshandiswa semakesi: mapaipi akasungirirwa asina musono uye mapaipi akasungirirwa eERW.
Pombi yekesi isina musono - pombi yekesi yakagadzirwa nepaipi yesimbi isina musono; Pombi yesimbi isina musono inoreva pombi yesimbi yakagadzirwa nenzira ina dzekuputira nekupisa, kuputira nechando, kuputira nekupisa uye kuputira nechando. Muviri wepombi pachawo hauna welds.
Muviri weERW – ERW (Electric Resistant Weld) pombi yesimbi yakagadzirwa nepombi yakasungirirwa yemagetsi inoreva pombi yakasungirirwa yemusono wenguva refu yakagadzirwa ne welding inodzivirirwa ne frequency resistance. Mapepa esimbi asina kugadzirwa (ma coil) emapombi akasungirirwa emagetsi anogadzirwa nesimbi ine carbon carbon low-carbon micro-alloy steel yakakungurutswa neTMCP (thermomechanical controlled process).
1. Pombi yesimbi isina musono inotenderwa neOD: uchishandisa nzira yekugadzira yakaputirwa nemoto, saizi inopedzwa pa8000°C. Kuumbwa kwezvinhu zvakagadziriswa, mamiriro ekutonhodza, uye mamiriro ekutonhodza kweroro zvine simba guru padhayamita yaro yekunze, saka zvakaoma kudzora dhayamita yekunze nemazvo, uye huwandu hwekuchinja-chinja hwakakura. Pombi yesimbi yeERW: inoumbwa nekukotama kunotonhora, uye dhayamita yayo inoderedzwa ne0.6%. Tembiricha yekushanda inogara yakafanana patembiricha yemumba, saka dhayamita yekunze inodzorwa nemazvo, uye huwandu hwekuchinja-chinja hudiki, izvo zvinobatsira kubvisa mabhurukwa eganda matema;
2. Pombi yesimbi isina musono ine ukobvu hwemadziro: Inogadzirwa nesimbi yakatenderera inoboorwa, uye kutsauka kweukobvu hwemadziro kwakakura. Kupfungaira kunopisa kunotevera kunogona kubvisa kusaenzana kweukobvu hwemadziro, asi michina yemazuva ano inogona kungoidzora mukati me ±5~10%t. Pombi yesimbi yeERW: Paunoshandisa hot rolled coil sezvinhu zvisina kugadzirwa, kushivirira kweukobvu hwemazuva ano hwehot rolling kunogona kudzorwa mukati me 0.05mm.
3. Zvikanganiso zviri pamusoro pekunze kwechinhu chinoshandiswa pakuonekwa kwepombi yesimbi isina musono hazvigone kubviswa panguva yekumonera kwesimbi inopisa, asi zvinogona kupukutwa chete mushure mekunge chigadzirwa chapera, kurova kwesimbi kunosara mushure mekuboorwa kunogona kubviswa zvishoma chete panguva yekuderedza madziro. Pombi yesimbi yeERW inogadzirwa nehot rolled coil sezvinhu zvakabikwa. Hunhu hwepamusoro pecoil hwakafanana nehunhu hwepamusoro pepombi yesimbi yeERW. Hunhu hwepamusoro pecoils dzinopisa dzakamonerwa huri nyore kudzora uye ndehwemhando yepamusoro. Nokudaro, hunhu hwepamusoro pepombi yesimbi yeERW huri nani kupfuura hwepombi yesimbi isina musono.
4. Pombi yesimbi isina musono yakaita denderedzwa: uchishandisa nzira yekumonera inopisa. Kuumbwa kwepombi yesimbi, mamiriro ekutonhodza uye mamiriro ekutonhodza kwerori zvine simba guru padhayamita yayo yekunze, saka zvakaoma kudzora dhayamita yekunze nemazvo, uye huwandu hwekuchinja-chinja hwakakura. Pombi yesimbi yeERW: inogadzirwa nekukombama kunotonhora, dhayamita yekunze inodzorwa nemazvo, uye huwandu hwekuchinja-chinja hudiki.
5. Kuedza Kubata Simba Hunhu hwekubata simba hwemapaipi esimbi asina musono uye mapaipi esimbi eERW zvinoenderana nezvinodiwa zveAPI, asi simba remapaipi esimbi asina musono rinowanzova pamuganhu wepamusoro, uye ductility iri pamuganhu wakaderera. Kusiyana neizvi, indekisi yesimba remapaipi esimbi eERW iri mumamiriro akanakisa, uye indekisi yepurasitiki yakakwira ne33.3% kupfuura yakajairwa. Chikonzero ndechekuti sezvinhu zvisina kugadzirwa zvepaipi yesimbi yeERW, mashandiro ehot rolled coil anovimbiswa nekunyungudutsa micro-alloy, kunatswa kwekunze kwefurnace, uye kutonhora nekutenderera; purasitiki. Zvine musoro kusangana.
6. Zvinhu zvakabikwa zvepaipi yesimbi yeERW ihot-rolled coil, iyo ine kunyatsojeka kwakanyanya mukutenderera, izvo zvinogona kuve nechokwadi chekuti chikamu chimwe nechimwe checoil chinoshanda zvakaenzana.
7. Zvinhu zvisina kugadzirwa zveERW hot rolled steel coil pombi ine saizi yezviyo zvinoshandisa billet yakafara uye yakakora inoenderera mberi yekukanda, pamusoro peganda rakatsetseka rakasimba, hapana nzvimbo yemakristaro ekoramu, shrinkage porosity uye pores, kutsauka kwemusanganiswa kudiki. , uye chimiro chacho chakabatana; kudzora mukuita kwekumonera kunotevera. Kushandisa tekinoroji yekumonera inotonhora kunowedzerawo kuona saizi yezviyo zvezviyo.
8. Kuyedzwa kwekutsvedza kwepombi yesimbi yeERW kwakabatana nehunhu hwezvinhu zvakagadziriswa uye maitiro ekugadzira pombi. Kufanana kweukobvu hwemadziro uye kutenderera kweoval zviri nani kupfuura mapaipi esimbi asina musono, ndicho chikonzero chikuru chekuti kuramba kwekudonha kwakakwira kupfuura kwemapaipi esimbi asina musono.
9. Kuedza Kukanganisa Nekuti kusimba kwechinhu chepasi chepombi yesimbi yeERW kwakakwira kakawanda kupfuura kwepombi yesimbi isina musono, kusimba kweweld ndiyo kiyi yepombi yesimbi yeERW. Nekudzora huwandu hwetsvina muzvinhu zvakabikwa, kukwirira uye kutungamira kweburr yekucheka, chimiro chemucheto wekugadzira, kona yekukwevera, kumhanya kwewelding, simba rekudziisa uye frequency, huwandu hwewelding extrusion, tembiricha yepakati yekudzora frequency uye kudzika, kureba kwechikamu chekutonhodza mhepo nezvimwe zvikamu zvemaitiro zvinovimbiswa. Kusimba kweweld yesimba kunosvika kupfuura 60% yesimbi yesimbi yesimbi. Nekuwedzera kugadziriswa, simba rekubata kweweld rinogona kuva pedyo nesimba resimbi yesimbi yesimbi, izvo zvinoita kuti ishande zvakanaka.
10. Kuyedza Kuputika Kushanda kwekuyedza kuputika kwemapaipi esimbi eERW kwakakwira zvakanyanya kupfuura zvinodiwa, kunyanya nekuda kwekuenzana kwakanyanya kweukobvu hwemadziro uye dhayamita yekunze yakafanana yemapaipi esimbi eERW.
