Imibhobho yentsimbi engenamthungo

Imibhobho yentsimbi engenamthungo yenziwe ngentsimbi epheleleyo, kwaye akukho zithungo phezu komhlaba. Zibizwa ngokuba yimibhobho yentsimbi engenamthungo. Ngokwendlela yokuvelisa, imibhobho engenamthungo yahlulwe yaba yimibhobho eshushu, ibhobho epholileyo, imibhobho epholileyo, imibhobho ekhutshiweyo, i-jacking pipes, njl.n imibhobho ekhethekileyo. Imibhobho enemilo ekhethekileyo inesikwere, i-oval, unxantathu, ihexagon, imbewu yemelon, inkwenkwezi, imibhobho enamaphiko kunye nezinye iimilo ezininzi ezintsonkothileyo. Ubukhulu bedayamitha yi-650mm kwaye ubuncinci bedayamitha yi-0.3mm. Ngokweendlela ezahlukeneyo zokusetyenziswa, kukho imibhobho enodonga olungqingqwa kunye nemibhobho ebhityileyo. Imibhobho yentsimbi engenamthungo isetyenziswa ikakhulu njengemibhobho yepetroleum yokomba yejoloji, imibhobho eqhekekileyo yeekhemikhali zepetroli, imibhobho yebhoyila, imibhobho ethwalayo, kunye nemibhobho yentsimbi echanekileyo yolwakhiwo oluphezulu lweemoto, iitrektara, kunye nenqwelomoya. Umbhobho wentsimbi ongenamathungo ecaleni komda wecandelo lawo elinqamlezayo. Ngokweendlela ezahlukeneyo zokuvelisa, ihlulwe ibe yimibhobho eshushu, ibhobho epholileyo, ibhobho epholileyo, imibhobho ekhutshiweyo, i-jacking pipes, njl., zonke zinemigaqo yazo yenkqubo. Izinto eziphathekayo zibandakanya isinyithi esiqhelekileyo kunye nekhwalithi ephezulu ye-carbon structural steel (Q215-A ~ Q275-A kunye ne-10 ~ 50 yentsimbi), intsimbi ephantsi ye-alloy (09MnV, 16Mn, njl.), intsimbi ye-alloy, insimbi engenasici, njl. ukusetyenziswa, yahlulwe kusetyenziso oluqhelekileyo (isetyenziselwa amanzi, imibhobho yerhasi kunye neenxalenye zesakhiwo, iindawo zoomatshini) kunye nokusetyenziswa okukhethekileyo (ezisetyenziselwa iibhoyila, ukuhlola i-geological, iibheringi, ukuxhathisa i-asidi, njl.). ① Eyona nkqubo yemveliso yombhobho wentsimbi ongenamthungo oqengqelekayo (△ Eyona nkqubo yokuhlola):

Inkqubo yokuvelisa umbhobho wentsimbi jikelele engenamthungo inokwahlulwa ibe ngumzobo obandayo kunye nokuqengqeleka okushushu. Inkqubo yokuvelisa umbhobho wensimbi engenamthungo epholileyo ngokuqhelekileyo inzima ngakumbi kunokuqengqeleka okushushu. Umbhobho ongenanto kufuneka uqale ugqitywe ngee-roller ezintathu, kwaye emva koko uvavanyo lokulinganisa kufuneka lwenziwe emva kwe-extrusion. Ukuba akukho mpendulo iqhekeka kumphezulu, umbhobho ojikelezayo kufuneka unqunywe ngumatshini wokusika kwaye unqunywe kwi-billet malunga nemitha enye ubude. Emva koko faka inkqubo yokukhupha. Ukucoca kufuneka kufakwe ulwelo olumuncu. Xa ukhetha, qaphela ukuba kukho inani elikhulu leebhola phezu komhlaba. Ukuba kukho ubuninzi beebhubhu, kuthetha ukuba umgangatho wombhobho wensimbi awuhambisani nemigangatho ehambelanayo. Ngenkangeleko, imibhobho yentsimbi epholileyo eqengqelekayo imfutshane kunemibhobho yentsimbi engenamthungo. Ubukhulu bodonga lwemibhobho yentsimbi engenamthungo eqengqelekayo buncinci kunemibhobho yentsimbi engenamthungo eqengqelekayo, kodwa umphezulu ujongeka uqaqambile kunemibhobho yentsimbi engenamthungo eshinyeneyo, kwaye umphezulu awurhabaxa kakhulu, kwaye nedayamitha ayinayo. iibhula ezininzi kakhulu.
Imeko yokuhanjiswa kweebhobho zentsimbi ezingenamthungo ezishushu ziqengqeleka ngokuqhelekileyo zishushu kwaye ziphathwe ngobushushu phambi kokunikezelwa. Emva kokuhlolwa komgangatho, imibhobho yensimbi engenamthungo eshushu-eshushu kufuneka ikhethwe ngokungqongqo ngesandla ngabasebenzi, kwaye umphezulu kufuneka uthanjiswe ngeoli emva kokuhlolwa komgangatho, kulandele iimvavanyo ezininzi zomzobo obandayo. Emva kokunyanga okutshisayo, iimvavanyo ze-perforation kufuneka zenziwe. Ukuba i-diameter ye-perforation inkulu kakhulu, ukulungiswa kunye nokulungiswa kufuneka kuqhutywe. Emva kokulungiswa, isixhobo sokuhambisa siya kuhanjiswa kwisixhobo sokukhangela isiphene ukuze kubonwe isiphene, kwaye ekugqibeleni sibhalwe, sicwangciswe ngokweenkcukacha, kwaye sibekwe kwindawo yokugcina impahla.
Umbhobho ojikelezileyo billet → ukufudumeza → ukugqobhoza → ukuqengqeleka okuqengqelekayo okuthathu, ukuqengqeleka okuthe gqolo okanye ukukhutshwa → ukususwa kwetyhubhu → ubungakanani (okanye ukunciphisa ubukhulu) → ukupholisa → ukulungisa → uvavanyo loxinzelelo loxinzelelo lwehydraulic (okanye ufunyaniso lwesiphene) → ukuphawula → ugcino umbhobho wentsimbi ongenamthungo uyenziwa yentsimbi ingot okanye eqinileyo ityhubhu billet ngokugqobhoza ibe ityhubhu erhabaxa, kwaye ke yenziwe ngokuqengqeleka eshushu, rolling ebandayo okanye umzobo obandayo. Iinkcukacha zombhobho wentsimbi engenamthungo zibonakaliswa ngeemilimitha zedayamitha yangaphandle * ubukhulu bodonga.
Idayamitha yangaphandle yombhobho ongenamthungo oqengqelekayo ngokuqhelekileyo mkhulu kune-32mm, kwaye ubukhulu bodonga yi-2.5-200mm. Idayamitha yangaphandle yombhobho wentsimbi engenamthungo epholileyo inokufikelela kwi-6mm, ubukhulu bodonga bungafikelela kwi-0.25mm, kwaye ububanzi bangaphandle bombhobho obhityileyo bunokufikelela kwi-5mm kwaye ubukhulu bodonga bungaphantsi kwe-0.25mm. Ukuqengqeleka okubandayo kunomgangatho ophezulu wokuchaneka kunokuqengqeleka okushushu.
Ngokuqhelekileyo, imibhobho yensimbi engenamthungo yenziwe nge-10, 20, 30, 35, 45 high-quality carbon steel, 16Mn, 5MnV kunye nezinye i-alloy low-alloy steels okanye i-40Cr, 30CrMnSi, 45Mn2, 40MnB kunye nezinye iintsimbi ze-alloy. Ukuqengqeleka okushushu okanye ukuqengqeleka okubandayo. Imibhobho engenamthungo eyenziwe ngentsimbi ephantsi yekhabhoni efana ne-10 kunye ne-20 isetyenziswa ikakhulu kwimibhobho yokuhambisa ulwelo. Imibhobho engenamthungo eyenziwe ngentsimbi yekhabhoni ephakathi efana ne-45 kunye ne-40Cr isetyenziselwa ukwenza iindawo ezinomatshini, ezifana neendawo ezithwele umthwalo wemoto kunye neetrektara. Ngokubanzi, imibhobho yentsimbi engenamthungo kufuneka iqinisekise amandla kunye novavanyo olucaba. Imibhobho yentsimbi eshushu eshushu ihanjiswa kwiindawo ezishushu ezishushu okanye ezinobushushu; imibhobho yentsimbi epholileyo ihanjiswa kumazwe aphethwe bubushushu.
I-Hot rolling, njengoko igama lithetha, linobushushu obuphezulu beqhekeza, ngoko ke ukuchasana kwe-deformation kuncinci kwaye inani elikhulu lokuguqulwa linokufezekiswa. Ukuthatha ukuqengqeleka kweepleyiti zetsimbi njengomzekelo, ubukhulu bebillet eqhubekayo yokuphosa ngokuqhelekileyo malunga ne-230mm, kwaye emva kokuqengqeleka kunye nokugqiba ukugqiba, ubukhulu bokugqibela yi-1 ~ 20mm. Kwangaxeshanye, ngenxa yomlinganiselo omncinci wobubanzi ukuya kubukhulu bepleyiti yentsimbi, iimfuno zokuchaneka komgangatho ziphantsi ngokwentelekiso, kwaye akulula ukuba neengxaki zokumila kwepleyiti, ikakhulu ukulawula ukuguquguquka. Kwabo baneemfuno zentlangano, ngokuqhelekileyo kuphunyezwa ngokuqengqeleka okulawulwayo kunye nokupholisa okulawulwayo, oko kukuthi, ukulawula ubushushu bokuqalisa kunye nobushushu bokugqibela bokuqengqeleka kokugqiba. Round tube billet → ukufudumeza → ukugqobhoza → iheading → annealing → pickling → i-oiling (copper plating) → iipasile ezininzi zomzobo obandayo (ukuqengqeleka okubandayo) → ityhubhu yebillet → unyango lobushushu → ukulungisa → uvavanyo loxinzelelo lwamanzi (ukubona impazamo) → ukumakisha → ukugcinwa.
