Ngokwendlela yokuvelisa, imibhobho yentsimbi inokwahlulwahlulwa ibe ziindidi ezimbini: imibhobho yentsimbi engenamthungo kunye nemibhobho yentsimbi edibeneyo. Phakathi kwazo, imibhobho yentsimbi ye-ERW lolona hlobo luphambili lwemibhobho yentsimbi edibeneyo. Namhlanje, sithetha kakhulu ngeentlobo ezimbini zemibhobho yentsimbi esetyenziswa njengezinto zokufaka iibhokisi: imibhobho yebhokisi engenamthungo kunye nemibhobho yebhokisi ye-ERW.
Umbhobho wekhava ongenamthungo – umbhobho wekhava owenziwe ngombhobho wentsimbi ongenamthungo; Umbhobho wentsimbi ongenamthungo ubhekisa kumbhobho wentsimbi owenziwe ngeendlela ezine zokuqengqeleka okushushu, ukuqengqeleka okubandayo, ukuzoba okushushu kunye nokuzoba okubandayo. Umzimba wombhobho ngokwawo awunazo ii-welds.
Umzimba we-ERW – Umbhobho wentsimbi we-ERW (Electric Resistant Weld) owenziwe ngombhobho we-electric weld ubhekisa kumbhobho we-longitudinal seam weld owenziwe nge-high frequency resistant welding. Amaphepha entsimbi eluhlaza (iikhoyili) zeepayipi ze-electric-weld zenziwe ngentsimbi ye-micro-alloy enekhabhoni ephantsi eqengqwe yi-TMCP (inkqubo elawulwa yi-thermomechanical).
1. Umbhobho wentsimbi ongenamthungo onyamezelayo we-OD: usebenzisa inkqubo yokwenza i-hot-rolled form, ubungakanani bugqitywa malunga ne-8000°C. Ukwakheka kwezinto eziluhlaza, iimeko zokupholisa, kunye nemeko yokupholisa yomsongo zinempembelelo enkulu kububanzi bawo bangaphandle, ngoko ke kunzima ukulawula ngokuchanekileyo ububanzi bangaphandle, kwaye uluhlu lokuguquguquka lukhulu. Umbhobho wentsimbi we-ERW: wenziwa ngokugoba okubandayo, kwaye ububanzi bawo buncitshiswa nge-0.6%. Ubushushu benkqubo buhlala buhleli kubushushu begumbi, ngoko ububanzi bangaphandle bulawulwa ngokuchanekileyo, kwaye uluhlu lokuguquguquka luncinci, olunceda ekususweni kwama-buckle esikhumba amnyama;
2. Umbhobho wentsimbi ongenamthungo onokunyamezela ubukhulu bodonga: Wenziwa ngokugqobhoza intsimbi engqukuva, kwaye ukuphambuka kobukhulu bodonga kukhulu. Ukuqengqeleka okushushu okulandelayo kunokuphelisa ukungalingani kobukhulu bodonga, kodwa oomatshini banamhlanje banokukulawula kuphela ngaphakathi kwe-±5~10%t. Umbhobho wentsimbi we-ERW: Xa usebenzisa i-hot rolled coil njengezinto eziluhlaza, ukunyamezela ubukhulu bokuqengqeleka okushushu kwanamhlanje kunokulawulwa ngaphakathi kwe-0.05mm.
3. Iziphene kumphezulu wangaphandle wento yokusebenza esetyenziselwa ukubonakala kombhobho wentsimbi engenamthungo azinakususwa kwinkqubo yokuqengqeleka okushushu, kodwa zinokucolwa kuphela emva kokuba imveliso egqityiweyo igqityiwe, ukubetheka kwe-helical okushiyekileyo emva kokubhoboza kunokususwa kancinci kuphela kwinkqubo yokunciphisa iindonga. Umbhobho wentsimbi ye-ERW wenziwe nge-hot rolled coil njengezinto eziluhlaza. Umgangatho womphezulu we-coil uyafana nomgangatho womphezulu wombhobho wentsimbi ye-ERW. Umgangatho womphezulu wee-hot rolled coils kulula ukuwulawula kwaye ungowomgangatho ophezulu. Ke ngoko, umgangatho womphezulu wombhobho wentsimbi ye-ERW ungcono kakhulu kunowombhobho wentsimbi engenamthungo.
4. Umbhobho wentsimbi ongqukuva ongenamthungo: usebenzisa inkqubo yokuqengqeleka eshushu. Ukwakheka kwezinto eziluhlaza zombhobho wentsimbi, iimeko zokuphola kunye nemeko yokuphola yomsongo zinempembelelo enkulu kububanzi bawo bangaphandle, ngoko ke kunzima ukulawula ngokuchanekileyo ububanzi bangaphandle, kwaye uluhlu lokuguquguquka lulukhulu. Umbhobho wentsimbi we-ERW: uveliswa kukugoba okubandayo, ububanzi bangaphandle bulawulwa ngokuchanekileyo, kwaye uluhlu lokuguquguquka luncinci.
5. Uvavanyo lokuThatha Iipropati zokuThatha zepayipi yentsimbi engenamthungo kunye nepayipi yentsimbi ye-ERW ziyahambelana nemigangatho ye-API, kodwa amandla epayipi yentsimbi engenamthungo ngokubanzi akwimida ephezulu, kwaye ukuthamba kukwimida esezantsi. Ngokwahlukileyo koko, isalathisi samandla sepayipi yentsimbi ye-ERW sikwimeko entle kakhulu, kwaye isalathisi seplastiki siphezulu ngama-33.3% kunomgangatho. Isizathu kukuba njengezinto eziluhlaza zepayipi yentsimbi ye-ERW, ukusebenza kwekhoyili eqengqelekayo eshushu kuqinisekiswa ngokunyibilikisa i-micro-alloy, ukucocwa ngaphandle kwesithando somlilo, kunye nokupholisa nokuqengqeleka okulawulwayo; iplastiki. Ukudibana okufanelekileyo.
6. Izinto ezisetyenziswa kumbhobho wentsimbi ye-ERW yi-hot-rolled coil, echanekileyo kakhulu kwinkqubo yokuqengqeleka, enokuqinisekisa ukusebenza okufanayo kwenxalenye nganye ye-coil.
7. Izinto eziluhlaza zombhobho we-coil yentsimbi egoqwe ngobushushu ye-ERW enobukhulu bengqolowa isebenzisa i-billet ebanzi netyebileyo yokuphosa eqhubekayo, umaleko wokuqina kwengqolowa entle umphezulu utyebile, akukho ndawo yeekristale zekholamu, ukuxinana kwe-porosity kunye nee-pores, ukuphambuka kokwakheka kuncinci. , kwaye isakhiwo sincinci; ulawulo kwinkqubo yokuqengqeleka elandelayo Ukusetyenziswa kwetekhnoloji yokuqengqeleka okubandayo kuqinisekisa ubungakanani bengqolowa yezinto eziluhlaza.
8. Uvavanyo lokumelana nokutyibilika kombhobho wentsimbi ye-ERW lunxulumene neempawu zezinto eziluhlaza kunye nenkqubo yokwenziwa kombhobho. Ukufana kobukhulu bodonga kunye nokuma kwe-oval kungcono kakhulu kunemibhobho yentsimbi engenamthungo, yiyo loo nto ibangela ukuba ukumelana nokuwa kuphakame kunokwemibhobho yentsimbi engenamthungo.
9. Uvavanyo lwempembelelo Ngenxa yokuba ukuqina kwezinto ezisisiseko zombhobho wentsimbi we-ERW kuphindwe kaninzi kunombhobho wentsimbi ongenamthungo, ukuqina kwe-weld yeyona nto iphambili kumbhobho wentsimbi we-ERW. Ngokulawula umxholo wokungcola kwizinto eziluhlaza, ukuphakama kunye necala le-cutting burr, imilo yomphetho wokwenza, i-engile ye-welding, isantya se-welding, amandla okufudumeza kunye ne-frequency, umthamo we-welding extrusion, ubushushu be-retraction ye-frequency ephakathi kunye nobunzulu, ubude becandelo lokupholisa umoya kunye nezinye iiparameter zenkqubo ziyaqinisekiswa. Impembelelo ye-weld yamandla ifikelela ngaphezulu kwe-60% yesinyithi esisisiseko. Ngokwenziwa ngcono ngakumbi, amandla empembelelo e-weld anokusondela kumandla esinyithi esisisiseko, okuqinisekisa ukusebenza okungenangxaki.
10. Uvavanyo oluqhumayo Ukusebenza kovavanyo oluqhumayo lwemibhobho yentsimbi ye-ERW kuphezulu kakhulu kuneemfuno ezisemgangathweni, ikakhulu ngenxa yokufana okuphezulu kobukhulu bodonga kunye nobubanzi obufanayo bangaphandle bemibhobho yentsimbi ye-ERW.
