Imbali yophuhliso lombhobho wesinyithi ongenamthungo
Imveliso yemibhobho yentsimbi engenamthungo inembali ephantse ibe yiminyaka eli-100. Abazalwana baseJamani baseMannesmann baqala ukuvelisa i-roll cross rolling piercer ezimbini ngo-1885, kunye ne-periodic pipe mill ngo-1891. Ngo-1903, i-Swiss RC stiefel yasungula i-automatic pipe mill (ekwaziwa ngokuba yi-top pipe mill). Emva koko, kwavela oomatshini abahlukeneyo bokwandisa abafana ne-continuous pipe mill kunye ne-pipe jacking machine, abaqala ukwenza ishishini lemibhobho yentsimbi engenamthungo yanamhlanje. Ngeminyaka yoo-1930, ngenxa yokusetyenziswa kwe-three roll pipe rolling mill, i-extruder kunye ne-periodic cold rolling mill, iintlobo ngeentlobo kunye nomgangatho wemibhobho yentsimbi waphucuka. Ngeminyaka yoo-1960, ngenxa yokuphuculwa kwe-continuous pipe mill kunye nokuvela kwe-three roll piercer, ingakumbi impumelelo ye-tension reducing mill kunye ne-continuous casting billet, ukusebenza kakuhle kwemveliso kwaphucuka kwaye ukukhuphisana phakathi kwe-seamless pipe kunye ne-welded pipe kwaphucuka. Ngeminyaka yoo-1970, i-seamless pipe kunye ne-welded pipe zazihambelana nesantya, kwaye imveliso ye-world steel pipe yanda ngesantya esingaphezulu kwe-5% ngonyaka. Ukususela ngo-1953, iTshayina ibeke ukubaluleka kuphuhliso lweshishini leepayipi zentsimbi ezingenamthungo, kwaye ekuqaleni yenze inkqubo yemveliso yokuqengqa zonke iintlobo zeepayipi ezinkulu, eziphakathi nezincinci. Ngokubanzi, iipayipi zobhedu nazo zisebenzisa iinkqubo zokuqengqa kunye nokubhoboza iipayipi.
Ukusetyenziswa kunye nokuhlelwa kombhobho wesinyithi ongenamthungo
Isicelo:
Umbhobho wentsimbi engenamthungo luhlobo lwentsimbi yecandelo lezoqoqosho, edlala indima ebaluleke kakhulu kuqoqosho lwelizwe. Isetyenziswa kakhulu kwi-petroleum, kushishino lweekhemikhali, kwibhoyila, kwisikhululo samandla, kwiinqanawa, kwimveliso yoomatshini, kwiimoto, kwiinqwelomoya, kwi-aerospace, kumandla, kwi-geology, kulwakhiwo, kushishino lwezomkhosi nakwamanye amasebe.
Udidi:
① Ngokwemilo yecandelo: umbhobho wecandelo elijikelezayo kunye nombhobho wecandelo elikhethekileyo.
2 ngokwezinto eziphathekayo: umbhobho wesinyithi sekhabhoni, umbhobho wesinyithi se-alloy, umbhobho wesinyithi esingenasici kunye nombhobho odibeneyo.
③ ngokwemo yoqhagamshelo: umbhobho woqhagamshelo onemisonto kunye nombhobho odibeneyo.
2 ngokwendlela yokuvelisa: umbhobho wokuqengqeleka oshushu (ukukhupha, ukugquma kunye nokwandisa) kunye nombhobho wokuqengqeleka obandayo (umzobo).
2 ngokwenjongo: umbhobho webhoyila, umbhobho wequla leoyile, umbhobho wepayipi, umbhobho wolwakhiwo kunye nombhobho wesichumiso seekhemikhali.
Itekhnoloji yokuvelisa umbhobho wesinyithi ongenamthungo
① Inkqubo ephambili yemveliso (inkqubo ephambili yokuhlolwa) yombhobho wentsimbi engenamthungo oshushu ogoqwe ngobushushu:
Ukulungiswa kunye nokuhlolwa kwetyhubhu engenanto → ukufudumeza ityhubhu engenanto → ukugqobhoza → ukuqengqeleka kwetyhubhu → ukufudumeza kwakhona ityhubhu eluhlaza → ubungakanani (ukunciphisa) → unyango lobushushu → ukolula ityhubhu egqityiweyo → ukugqiba → ukuhlolwa (okungonakalisiyo, okubonakalayo kunye nokwekhemikhali, uvavanyo lwebhentshi) → indawo yokugcina impahla.
② Iinkqubo eziphambili zemveliso yombhobho wentsimbi engenamthungo oqengqelekayo (otsaliweyo)
Ukulungiswa okungenanto → ukucola kunye nokuthambisa → ukuqengqeleka okubandayo (ukuzoba) → unyango lobushushu → ukulula → ukugqiba → ukuhlolwa.
Itshathi yokuhamba kwenkqubo yemveliso yombhobho wentsimbi engenamthungo oshushu oqengqelweyo ngolu hlobo lulandelayo:
