Inkcazelo emfutshane:
Lo Mbhobho we-Alloy Steel kunye ne-12cr1MOV Material ngumbhobho wensimbi ongenamthungo onokusetyenziswa kwi-petroleum, iikhemikhali, amandla ombane kunye ne-boiler applications.Ineempawu zokumelana nokubanda, ukumelana nobushushu kunye nokumelana nokugqwala.12Cr1MoV luhlobo lombhobho we-alloy.Injongo ephambili kukwenza iinxalenye zesakhiwo sentsimbi kwibhoyili.
Sikholelwa: Ukusungula izinto ezintsha ngumphefumlo nomoya wethu.Umgangatho ophakamileyo bubomi bethu.Umthengi kufuneka abe nguThixo wethu wokunyamezela iMimamo 15mng/20mng/15crmog/12cr1movg Building-Materials IGas Oil Pipelines St35.8/SA106b/SA106c/SA210A/SA210c Boiler Seamless Steel Pipe, inikezela ngenkqubo yethu ekhethekileyo yokuphumelela. abathengi abangaguquguqukiyo umgangatho ophezulu, okusivumela ukuba silawule iindleko, sicwangcise umthamo kunye nokugcina ukuhanjiswa kwexesha.
Sikholelwa: Ukusungula izinto ezintsha ngumphefumlo nomoya wethu.Umgangatho ophakamileyo bubomi bethu.Umthengi kufuneka abe nguThixo wethuItyhubhu yentsimbi yaseTshayina kunye nombhobho wentsimbi, Ngomgangatho ophezulu, ixabiso elifanelekileyo, ukuhanjiswa kwexesha kunye neenkonzo ezilungelelanisiweyo kunye neenkonzo ezilungiselelwe ukunceda abathengi bafezekise iinjongo zabo ngempumelelo, inkampani yethu inendumiso kwiimarike zasekhaya nezangaphandle.Abathengi bamkelekile ukuba baqhagamshelane nathi.
Ubushushu benkonzo yi-580 ℃, kwaye ipleyiti yentsimbi iyafuneka ukuba ibe namandla okunyamezela ubushushu obuphezulu.Isitya sentsimbi sihanjiswa kwisimo esiqhelekileyo kunye nesomsindo.Umbhobho we-alloy we-12Cr1MoVG usekelwe kwi-high-quality carbon structural steel, kwaye enye okanye izinto ezininzi ze-alloy zongezwa ngokufanelekileyo ukuphucula iimpawu zomatshini, ukuqina kunye nokuqina kwentsimbi.Iimveliso ezenziwe ngentsimbi enjalo zidla ngokufuna unyango lobushushu (i-normalizing okanye i-quenching and tempering);Amalungu kunye namacandelo enziwe ngawo ahlala efuna ukucinywa kunye nokufudumeza okanye unyango lwekhemikhali yangaphezulu (i-carburizing, i-nitriding, njl.), ukucima umphezulu okanye ukucima i-high-frequency ngaphambi kokusetyenziswa.Ngoko ke, ngokweendlela ezahlukeneyo zeekhemikhali (ikakhulukazi umxholo wekhabhoni), iinkqubo zonyango lobushushu kunye nokusetyenziswa, iintsimbi ezinjalo zinokuthi zihlulwe ngokufanelekileyo zibe yi-carburized, i-Quenched and tempered and nitrided steels.
Okokuqala, inokuba yi-100% isetyenziswe kwakhona, igcine amandla kunye nokukhuselwa kwendalo.
Okwesibini, ineplastiki ephezulu kakhulu kwaye ingasetyenziselwa imveliso yesibini kunye nokulungiswa.
Okwesithathu, ine-conductivity efanelekileyo ye-thermal kunye nokukwazi ukukhwela ubushushu obuphezulu.
Okwesine, inokumelana ne-oxidation elungileyo kunye nokumelana nomhlwa.
Okwesihlanu, inomsebenzi omhle wokubanda kunye nokutshisa.
I-12Cr1MoVG luhlobo lwe-chromium molybdenum ingxubevange yombhobho wentsimbi, apho amacandelo ekhemikhali aphambili yi-carbon 0.08-0.15, i-silicon 0.17-0.37, i-manganese 0.40-0.70, i-phosphorus engekho ngaphezu kwe-0.035, i-sulfure engekho ngaphezu kwe-100, i-0. molybdenum 0.25-0.35, alum 0.15-0.30, njl.
Okokuqala, isetyenziswa ikakhulu ukwenza iityhubhu zealloy ezinoxinzelelo oluphezulu lokufudumeza imiphezulu yeebhoyila zamanzi ezinoxinzelelo oluphezulu nangaphezulu.
Okwesibini, isetyenziswa kakhulu kwii-superheaters, iiheader kunye ne-steam ducts eziphambili zasekhaya zoxinzelelo oluphezulu, uxinzelelo oluphezulu kunye ne-subcritical power stations boilers.
Okwesithathu, imibhobho edayamitha emikhulu isetyenziswa ikakhulu njengeeheader kunye neMibhobho yoMphunga ePhambili eneparamitha zomphunga ongaphantsi kwama-565 ℃.
Okokuqala, ukuqengqeleka okushushu (umbhobho wentsimbi ongenamthungo) ukuhamba kwenkqubo:
Ityhubhu engqukuva billet → ukufudumeza → ukugqobhoza → ukuqengqeleka okuthathu okunqamlezayo, ukuqengqeleka okuqhubekayo okanye ukukhutshwa kombhobho → ukuhluba kombhobho → ukulinganisa (okanye ukucutha) → ukupholisa → ibhilethi → ukolula → uvavanyo lwe-hydrostatic (okanye ukubhaqa isiphene) → ukumakisha → ukugcina.
Okwesibini, umzobo obandayo (ukuqengqeleka) ukuhamba kwenkqubo yombhobho wentsimbi engenamthungo:
Umzobo wetyhubhu engqukuva → ukufudumeza → ukugqobhoza → ukugqobhoza → ukuqhola → ukuchola → ukugquma ioyile (icwecwe lobhedu) → umzobo wokudlula okubandayo (ukuqengqeleka okubandayo) → ityhubhu yebhiliti → unyango lobushushu → ukolula → uvavanyo lwe-hydrostatic (okanye ukubhaqa isiphene) → ukuphawula → ukugcina impahla.
