Imbali yophuhliso lombhobho wentsimbi engenamthungo
Imveliso yombhobho yentsimbi engenamthungo inembali ephantse ibe yi-100 iminyaka.Abazalwana baseJamani bakwaMannesmann baqala ukuqulunqa i- two roll cross rolling piercer ngo-1885, kunye ne-periodic pipe mill ngo-1891.Emva koko, oomatshini bokwandiswa abahlukeneyo abanjengomatshini wokusila wemibhobho oqhubekayo kunye noomatshini wokutyhalela umbhobho wavela, owaqala ukwenza ishishini lemibhobho yentsimbi yanamhlanje engenamthungo.Ngeminyaka yoo-1930, ngenxa yokusetyenziswa kwemibhobho emithathu yokusila, i-extruder kunye ne-periodic cold rolling mill, iindidi kunye nomgangatho wemibhobho yentsimbi yaphuculwa.Ngeminyaka yoo-1960, ngenxa yokuphuculwa komatshini wokusila oqhubekayo kunye nokuvela kombhobho wokusila amathathu, ingakumbi impumelelo yokunciphisa intambo yokusila kunye nebillet eqhubekayo yokuphosa, impumelelo yemveliso yaphuculwa kunye nokhuphiswano phakathi kombhobho ongenamthungo kunye nombhobho odityanisiweyo uye wandiswa.Ngeminyaka yoo-1970, umbhobho ongenamthungo kunye nombhobho odityanisiweyo wawugcina isantya, kwaye ukuphuma kombhobho wentsimbi yehlabathi kunyuke ngesantya esingaphezu kwe-5% ngonyaka.Ukususela ngo-1953, i-China incamathele ukubaluleka kuphuhliso lweshishini lombhobho wentsimbi engenamthungo, kwaye ekuqaleni yenze inkqubo yemveliso yokuqengqeleka zonke iintlobo zemibhobho emikhulu, ephakathi kunye nencinci.Ngokuqhelekileyo, umbhobho wobhedu wamkela iinkqubo ze-billet cross rolling kunye nokubhoboza.
Ukusetyenziswa kunye nokuhlelwa kombhobho wensimbi engenamthungo
Isicelo:
Umbhobho wensimbi ongenamthungo luhlobo lwentsimbi yecandelo loqoqosho, edlala indima ebaluleke kakhulu kuqoqosho lwelizwe.Isetyenziswa kakhulu kwi-petroleum, kwishishini lemichiza, kwibhoyila, kwisikhululo samandla, inqanawa, ukwenziwa koomatshini, iimoto, inqwelomoya, inqwelomoya, i-aerospace, amandla, ijoloji, ulwakhiwo, ishishini lomkhosi namanye amasebe.
Ukuhlelwa:
① Ngokwemilo yecandelo: umbhobho wecandelo lesetyhula kunye nombhobho wecandelo elikhethekileyo.
② ngokwezinto eziphathekayo: umbhobho we-carbon steel, umbhobho wensimbi ye-alloy, umbhobho wensimbi engenasici kunye nombhobho odibeneyo.
③ ngokwendlela yoqhagamshelo: umbhobho wodibaniso oludityanisiweyo kunye nombhobho odityanisiweyo.
④ ngokwendlela yokuvelisa: ukuqengqeleka okutshisayo (i-extrusion, i-jacking kunye nokwandiswa) umbhobho kunye nombhobho obandayo (umzobo).
⑤ ngokwenjongo: umbhobho webhoyila, umbhobho we-oyile, umbhobho wemibhobho, umbhobho wolwakhiwo kunye nombhobho wesichumiso sekhemikhali.
Itekhnoloji yemveliso yombhobho wentsimbi engenamthungo
① Inkqubo engundoqo yemveliso (inkqubo yokuhlolwa engundoqo) yombhobho wentsimbi eshushu eqengqelekayo:
Ukulungiswa kwetyhubhu engenanto kunye nokuhlolwa → ukufudumeza ityhubhu engenanto → ukugqobhoza → ukuqengqeleka kwetyhubhu → ukufudumeza ityhubhu ekrwada → ukulinganisa (ukunciphisa) → unyango lobushushu → ukulungiswa kwetyhubhu egqityiweyo → ukugqiba → ukuhlola (okungonakalisiyo, ngokomzimba nangokwekhemikhali, uvavanyo lwebhentshi) → ukugcina.
② Iinkqubo eziphambili zemveliso yombhobho wentsimbi oqengqelekayo (otsaliweyo) ongenamthungo
Ukulungiselela okungenanto → ukukha nokuthambisa → ukuqengqeleka okubandayo (umzobo) → ukunyanga ubushushu → ukulungisa → ukugqiba → ukuhlola.
Inkqubo yokuvelisa itshathi yombhobho wentsimbi eshushu eqengqelekayo ingenamthungo ngolu hlobo lulandelayo:
