Isishwankathelo:Ngenxa yokukhula ngokukhawuleza kwemizi-mveliso kunye nemfuno yamandla eIndiya, imfuneko yokusebenza okuphezuluimibhobho ye-alloyiye yanda kakhulu.A335 P91, umntu ophucukileyointsimbi ye-chromium-molybdenum alloy, iye yaba yinto ebalulekileyo kumacandelo aphambili afana nokuveliswa kwamandla, iikhemikhali zepetroli, kunye namandla enyukliya ngenxa yamandla ayo aphezulu obushushu, ukumelana nokuqhekeka, kunye nokumelana nokugqwala. Eli nqaku libonelela ngohlalutyo olunzulu lwemeko yesicelo, izinto eziqhubayo, kunye neendlela zexesha elizayoImibhobho ye-alloy ye-A335 P91kwimarike yaseIndiya.
1. Izinto ezingundoqo: Intshayelelo kwiUmbhobho we-A335 P91 Alloy
A335 P91yiintsimbi ye-ferritic alloyumbhobho ohambelana nomgangatho we-ASTM A335. Ulwakhiwo lwayo oluphambili lweekhemikhali yi-9% yeChromium kunye ne-1% yeMolybdenum, kunye nokongezwa okuncinci kweVanadium, iNiobium, kunye neNitrogen (yiyo loo nto ibizwa ngokuba yiP91). Ngokusebenzisa inkqubo yokulungisa ubushushu eqhelekileyo kunye nokufudumala, ifezekisa isakhiwo esincinci esinikezela ngeempawu zoomatshini ezingenakuthelekiswa nanto phantsi kobushushu obuphezulu (ukuya kuthi ga kwi-600°C nangaphezulu) kunye neemeko zoxinzelelo oluphezulu. Xa kuthelekiswa neemeko zemveli.imibhobho yentsimbi ye-alloynjenge-P22 okanye i-P11, i-P91 ivumela iindonga ezincinci kuxinzelelo olufanayo loyilo, inciphisa ubunzima bezixhobo, igcina iindleko zezinto, kwaye iphucula ukusebenza kakuhle kobushushu.

2. Amacandelo aPhambili oSetyenziso kwiMarike yaseIndiya
Izityalo zamandla obushushu:Le yeyona sicelo sikhulu nesibaluleke kakhulu se-P91imibhobho ye-alloyeIndiya. Njengoko iIndiya inyanzelisa ukwakhiwa kweeyunithi zamandla ezibaluleke kakhulu nezibaluleke kakhulu ukuphucula ukusebenza kakuhle nokunciphisa ukukhutshwa komoya, izinto zeP91 ziye zaba lolona khetho lukhethwayoimigca ephambili yomphungakwayephinda ufudumale imibhobho eshushuAmandla ayo okumelana nomphunga weparameter ephezulu (ngokwesiqhelo uxinzelelo >22MPa, ubushushu >560°C) bubalulekile ekusebenzeni ngokukhuselekileyo nangokufanelekileyo kwezityalo zamandla.
Ishishini lePetrochemical:Kwiindawo zokucoca kunye nezityalo zeekhemikhali, imibhobho ye-P91 isetyenziswa kwiiyunithi ezibalulekileyo ezifanaUkuqhekeka kweFluid Catalytic (FCC)kwayeIiyunithi zokucoca ngamanzi, ephatha ulwelo kunye nee-hydrocarbons ezishushu kakhulu, ezixinezelekileyo, nezirhabaxa.
Icandelo laMandla eNyukliya:I-P91imibhobho yentsimbi ye-alloyfumana usetyenziso kwiinkqubo ezithile ezincedisayo zezityalo zamandla enyukliya, njengeenkqubo zokufudumeza ezishushu kakhulu, nangona ziphantsi kweemfuneko ezingqongqo kakhulu.
Amanye amacandelo oShishino:Kubandakanya ukwenziwa kwebhoyila, iityhubhu ze-furnace yemizi-mveliso, kunye nezinye izinto ezahlukeneyoinkqubo yokuhambisa imibhobhoiinkqubo ezifuna ubushushu obuphezulu kunye nokumelana noxinzelelo.
3. Abaqhubi beMarike kunye nemingeni
Abaqhubi:
Imfuno yamandla:Uqoqosho lwaseIndiya olukhula ngokukhawuleza ludala ukunqongophala okukhulu kwamandla, nto leyo eqhuba utyalo-mali kwizikhululo zamandla ezintsha nezisebenzayo.
Ukuphuculwa Kokusebenza Kakuhle:Ubuchwepheshe obugqwesileyo bubaluleke kakhulu kuphuhliso lwecandelo lamandla eIndiya, nto leyo edala ngqo imfuno yezixhobo eziphambiliimibhobho ye-alloynjengeP91.
Utyalo-mali kwiZiseko zoPhuhliso:Utyalo-mali oluqhubekayo lukarhulumente kwiziseko zoshishino nezamandla lubonelela ngesantya sexesha elide kwimarike.
Ukuveliswa kweMveliso yasekuhlaleni:Iphulo elithi "Make in India" likhuthaza abavelisi beepayipi zasekhaya ukuba baphucule izakhono zobugcisa zokuvelisa umgangatho ophezuluimibhobho engenamthungo, ukunciphisa ukuxhomekeka ekungeniseni impahla kwamanye amazwe.
Imingeni:
Ixabiso Eliphezulu:Izinto ezintsonkothileyo kunye neenkqubo zokuvelisa ze-P91imibhobho ye-alloyoku kubangela ixabiso eliphezulu kakhulu kuneepayipi zentsimbi zekhabhoni eziqhelekileyo.
Iimfuno ezingqongqo zokuWelda:Ukuwelda imibhobho ye-P91 kufuna ukufudumeza okungqongqo kwangaphambili, ulawulo lobushushu phakathi kwee-interpass, kunye noNyango lobushushu emva kokuwelda (PWHT). Ifuna iingcali ezinobuchule obuphezulu, njengoko iinkqubo ezingafanelekanga zinokubangela ukungaphumeleli.
Ukuxhomekeka ekuNgenisweni:Nangona umthamo wasekhaya uyanda, eminye yemibhobho ye-P91 ekumgangatho ophezulu isaxhomekeke ekungenisweni kwempahla evela eYurophu, eTshayina, njl.
Umahluko woMgangatho:Umgangatho wemveliso ongaguqukiyo kwimarike wenza ukuba ukuqinisekisa ukuthotyelwa kokwakheka kweekhemikhali, iimpawu zoomatshini, kunye nemigangatho yesimo sonyango lobushushu kube yinto ebalulekileyo kukhuseleko lweprojekthi.
4. Imbono yexesha elizayo
Kwiminyaka ezayo, njengoko iIndiya iqhubeka nokuphucula amandla ayo okuvelisa umbane kunye nesiseko sayo semizi-mveliso, imfuno yokusebenza okuphezuluimibhobho ye-alloynjengeA335 P91Kulindeleke ukuba ihlale ikhula ngokuzinzileyo. Iindlela zemarike ziya kuthambekela kwiimveliso ezikumgangatho ophezulu nezithembekileyo zasekuhlaleni. Kwangaxeshanye, kuya kuvela imakethi enkulu exhasayo yolawulo lonke lwemibhobho, kubandakanya iinkonzo zokuwelda kunye nokuhlolwa,. Abavelisi abanakho ukubonelela ngeemveliso zeP91 ezikumgangatho ophezulu ezihlangabezana nemigangatho yamazwe ngamazwe (umz., i-ASTM, i-ASME) baya kubekwa kakuhle kule marike yaseIndiya enamandla.
