①Ukunyamezelana kwedayimitha yangaphandle
Umbhobho wentsimbi ongenamthungo: Kusetyenziswa inkqubo eshushu yokuqengqeleka, kwaye ubungakanani bugqitywe malunga ne-8000C. Ukubunjwa kwezinto eziluhlaza, iimeko zokupholisa, kunye nesimo sokupholisa imiqulu yombhobho wensimbi kunempembelelo enkulu kububanzi bayo bangaphandle. Ke ngoko, ulawulo lwedayamitha yangaphandle kunzima ukuchaneka kwaye luguquguquke. Uluhlu olukhulu.
Umbhobho wentsimbi we-ERW: wamkela ukugoba okubandayo kunye nokulinganisa nge-0.6% yokunciphisa ububanzi. Ubushushu benkqubo buhlala buhlala kwiqondo lokushisa, ngoko ke ububanzi bangaphandle bulawulwa ngokuchanekileyo kwaye uluhlu lokuguquguquka luncinci, olulungele ukupheliswa kwamabhanti amnyama;

②Ukunyamezela ukutyeba kweendonga
Umbhobho wentsimbi engenamthungo: Iveliswe ngokugqobhoza kwentsimbi engqukuva, ukutenxa kobukhulu bodonga kukhulu. Ukuqengqeleka okulandelayo okushushu kunokuphelisa ngokuyinxenye ukungalingani kodonga, kodwa okwangoku, ezona yunithi ziphambili zinokuwulawula kuphela ngaphakathi kwe ± 5 ~ 10% t.
I-ERW yensimbi yombhobho: iikhoyili ezishushu zisetyenziswe njengezinto eziluhlaza, kwaye ukunyamezela kobunzima bemicu yanamhlanje eshushu eshushu ingalawulwa ngaphakathi kwe-0.05mm.

③Imbonakalo
Iziphene zangaphandle zeendawo ezingenanto ezisetyenziswe kwimibhobho yensimbi engenamthungo ayikwazi ukupheliswa ngenkqubo eshushu. Zinokucocwa kuphela emva kokuba imveliso egqityiweyo igqityiwe. Umzila ojikelezayo oshiywe emva kokugqobhoza unokupheliswa ngokuyinxenye kuphela ngexesha lenkqubo yokunciphisa udonga.
Imibhobho yentsimbi ye-ERW isebenzisa iikhoyili eziqengqelekayo njengemathiriyeli ekrwada. Umgangatho womphezulu weekhoyili ngumgangatho womphezulu wemibhobho yentsimbi ye-ERW. Umgangatho womphezulu we-coil-rolled rolling kulula ukulawula kwaye unomgangatho ophezulu. Ke ngoko, umgangatho womphezulu wemibhobho yentsimbi ye-ERW ungcono kakhulu kunemibhobho yentsimbi engenamthungo.

④Ubungakanani
Umbhobho wentsimbi ongenamthungo: Ukusebenzisa inkqubo yokubumba eshushu, ukubunjwa kwezinto ezikrwada, iimeko zokupholisa, kunye nemo yokupholisa imiqulu yonke inempembelelo enkulu kwidayamitha yangaphandle yombhobho wentsimbi. Ngoko ke, ulawulo lwedayamitha yangaphandle kunzima ukulawula ngokuchanekileyo, kwaye uluhlu lokuguquguquka lukhulu.
Ipayipi yensimbi ye-ERW: Yenziwa ngokugoba okubandayo, ngoko ke ububanzi bangaphandle bulawulwa ngokuchanekileyo kwaye uluhlu lokuguquguquka luncinci.

⑤ Uvavanyo lwe-tensile
Iimpawu zokusebenza ze-tensile zemibhobho yensimbi engenamthungo kunye ne-ERW yensimbi yentsimbi zombini ihlangabezana nemigangatho ye-API, kodwa amandla emibhobho yensimbi engenamthungo ngokuqhelekileyo iphezulu kumda kwaye iplastiki iphantsi komda ophantsi. Ngokuthelekisa, isalathiso samandla se-ERW imibhobho yensimbi ingcono kakhulu, kwaye isalathisi seplastiki yi-33.3% ephezulu kunomgangatho. , isizathu kukuba ukusebenza kwee-coil-rolled-rolled, i-raw material ye-ERW ipayipi yensimbi, iqinisekisiwe ngokusebenzisa i-microalloying smelting, i-out-of-furnace refining, kunye nokulawulwa kokupholisa kunye nokuqengqeleka; imibhobho yensimbi engenamthungo ikakhulu ixhomekeke kwiindlela zokwandisa umxholo wekhabhoni, okwenza kube nzima ukuqinisekisa amandla kunye neplastiki. umdlalo ofanelekileyo.

⑥Ubunzima
Izinto eziluhlaza zeepayipi zensimbi ze-ERW - iikhoyili ezishushu ezishushu, zinokuchaneka okuphezulu kakhulu ekupholiseni okulawulwayo kunye nokuqengqeleka ngexesha lenkqubo yokujikeleza, enokuqinisekisa ukusebenza okufanayo kwazo zonke iindawo zeekhoyili.

⑦Ubungakanani beenkozo
Imathiriyeli ekrwada yombhobho wentsimbi we-ERW - i-coil eqengqeleke eshushu yenziwe ngebillet ebanzi kwaye engqindilili eqhubekayo yokuphosa, enomaleko oqinileyo wokuqina wengqolowa, akukho ndawo yekristale yekholomu, umngxuma wokushwabana kunye nokukhululeka, ukutenxa okuncinci kokwakheka, kunye noxineneyo. ubume kwinkqubo yokuqengqeleka elandelayo Phakathi kwabo, ukusetyenziswa kokupholisa okulawulwayo kunye nokulawulwa kobuchwephesha bokuqengqeleka buqinisekisa ngakumbi ubungakanani beenkozo zemathiriyeli ekrwada.

⑧ Ukuwa kovavanyo lokuxhathisa
Umbhobho wensimbi we-ERW ubonakaliswa yimathiriyeli ekrwada kunye nenkqubo yokwenza umbhobho. Ubungqingqwa bodonga lwayo olufanayo kunye ne-ovality ingcono kakhulu kunemibhobho yentsimbi engenamthungo, esona sizathu siphambili sokuba ukusebenza kwayo kokuchasana nokudilika kuphezulu kunemibhobho yentsimbi engenamthungo.

⑨Uvavanyo lwempembelelo
Ukusukela ukuba ukuqina kwempembelelo yesiseko semibhobho yentsimbi ye-ERW kuphindwe kaninzi kokwemibhobho yentsimbi engenamthungo, ukuqina kwempembelelo yentsimbi ngundoqo kwimibhobho yentsimbi ye-ERW. Ngokulawula umxholo wokungahlambuluki wezinto eziluhlaza, ukuphakama kunye nesalathiso se-slitting burrs, imilo yemiphetho eyenziweyo, i-angle ye-welding, isantya se-welding, amandla okufudumeza, kunye namaxesha, isixa se-welding extrusion, ubushushu obuphakathi bokurhoxiswa kunye nobunzulu, umoya. ubude becandelo lokupholisa kunye nezinye iiparamitha zenkqubo ziqinisekisa ukuba amandla empembelelo ye-weld afikelela ngaphezu kwe-60% yesiseko sesinyithi. Ukuba kuphuculwe ngakumbi, amandla empembelelo yeweld anokusondela kulowo wentsimbi yomzali. izinto eziphathekayo, okubangela ukusebenza ngokungenamthungo.

⑩Uvavanyo lokudubula
Ukusebenza kovavanyo olugqabhukileyo lwemibhobho yensimbi ye-ERW iphezulu kakhulu kuneemfuno eziqhelekileyo, ngokukodwa ngenxa yokufana okuphezulu kobukhulu bodonga kunye nobubanzi obungaphandle obufanayo bemibhobho yensimbi ye-ERW.

⑪Ukuthe tye
Imibhobho yensimbi engenamthungo yenziwe kwimo yeplastiki, kwaye kunye nomlawuli omnye (i-3 ukuya ku-4 amaxesha omlawuli wokujikeleza okuqhubekayo), ukuthe tye kwesiphelo sombhobho kunzima ukulawula;
Imibhobho yentsimbi ye-ERW icutshungulwa ngokubanda kwaye inokolulekwa kwi-intanethi kwimeko yedayamitha encitshisiweyo. Ukongeza, zande ngokungenasiphelo, ngoko ke ukuthe tye kungcono.

⑫ Isixa sentsimbi esetyenziselwa ukufakwa kwi-casing nganye kwi-10,000 yeemitha zomfanekiso
Ubukhulu bodonga lwemibhobho yentsimbi ye-ERW bufana kwaye ukunyamezela kobunzima bodonga akunanto, ngelixa umda wokuchaneka kokuchaneka kobunzima bodonga lwemibhobho yentsimbi engenamthungo yi-± 5% t, elawulwa ngokubanzi kwi-± 5 ~ 10% t. Ukuqinisekisa ukuba ubuncinci bodonga bungahlangabezana neemfuno ezisemgangathweni kunye nokusebenza, isisombululo kuphela kukunyusa ubuninzi bodonga ngokufanelekileyo. Ngoko ke, kwi-casing yeenkcukacha kunye nobunzima obufanayo, i-ERW imibhobho yentsimbi i-5 ukuya kwi-10% ubude kunemibhobho yentsimbi engenamthungo, okanye nangaphezulu, enciphisa ukusetyenziswa kwentsimbi ye-casing nganye kwi-10,000 yeemitha ze-footage nge-5 ukuya kwi-10%. Kwangexabiso elifanayo, imibhobho yentsimbi ye-ERW igcina abasebenzisi i-5 ukuya kwi-10% yeendleko zokuthenga.

Isishwankathelo: Nangona kunjalo, ngoku amazwe asekhaya kunye namazwe angaphandle asasebenzisa ezingenamthungo, kuba umgangatho wangoku wentsimbi yentsimbi ye-ERW yemibhobho yentsimbi inokulawulwa kuphela kweyona K55 ephezulu. Ukuba ibakala lentsimbi liphezulu, asinalo umthamo wemveliso yasekhaya. Ngokubhekiselele kwimarike yombhobho yentsimbi ye-ERW yangoku, izixhobo zokuvelisa zaseJapan kunye nobuchwepheshe bemveliso zisenokufikelela kwinqanaba elithile lokuvelisa i-casing, kodwa zinokuvelisa kuphela ukuya kwi-N80. Ukuba ufuna ukuvelisa i-P110 okanye amabakala aphezulu ensimbi, okwangoku kukho umda othile. Ubunzima, ngoko ke ERW umbhobho yentsimbi ingasetyenziswa kuphela njengewotshi.
