Kwishishini le-petrochemical, i-gasification yamalahle, amandla enyukliya kunye nezikhululo zamandla, iipleyiti zentsimbi eziphantsi kwe-alloy-resistant zisetyenziswa ngokubanzi ukwenza iinqanawa zoxinzelelo.Iimpawu eziphambili eChina ziyi-15CrMoG iipayipi ze-alloy eziphezulu zoxinzelelo (1.25Cr-O.5Mo), 12Cr2Mo (2.25Cr-1Mo) kunye ne-12Cr1MoV, njl njl. Umzekelo, i-hot-wall hydrogenation reactors isebenzisa kakhulu i-2.25Cr-1Mo) (25-150mm).), ngenxa yokuba izixhobo zisebenza phantsi kweemeko zokushisa okuphezulu, uxinzelelo oluphezulu kunye nokuxhatshazwa kwe-hydrogen ixesha elide, ngelixa liqwalasela ukuthintela ukukhutshwa kwe-embrittlement kwi-475 ° C, izinto ezifunekayo ukuba zibe nokucoceka okuphezulu, kunye nesulfure kunye ne-phosphorus. kulindeleke ukuba zibe ngaphantsi kwe-0.01% kunye ne-tin ephantsi kakhulu, Izinto ezinobungozi ezifana ne-antimony kunye ne-arsenic zifuna ukunyibilikiswa kwesithando sombane kunye nokucocwa kwangaphandle.
[3]Intsimbi yeziqhoboshi.
Intsimbi ye-Fastener yinto ephambili edlala indima ekudityanisweni kwee-injini ze-steam, ii-boilers kunye nezinye izixhobo ze-container-high-pressure.Ifuna umda owaneleyo wesivuno, uzinzo oluphezulu lokuphumla, iplastiki elungileyo ehlala ixesha elide kunye nobuntununtunu benotshi encinci yexesha elide.Ukumelana ne-oxidation kunye nokusebenza kakuhle kokusika.Iimpawu eziphambili eChina ziyi-25Cr2Mo, 25Cr2MoV, 25Cr2Mo1V, 20Cr1M01VNbTiB, njl., ezinokusetyenziswa kuluhlu lwe-500～570℃ ngokulandelanayo.La mabakala asetyenziswa ngokubanzi emva kokucima kunye nokuqunjelwa.
[4] Intsimbi ye-rotor (i-spindle, impeller).
Eyona shaft, i-impeller kunye ne-integrated forged rotor yenye yezinto eziphambili ze-injini yomphunga.Isixhobo siyafuneka ukuba sibe neepropathi ezilungileyo ezibanzi zoomatshini, ukuqina kokwaphuka, ukuxhathisa okuphezulu kokunyuka kunye namandla okunyamezela, kunye nokumelana nokudinwa kwe-thermal.Iimpawu ezisetyenziswa ngokuqhelekileyo ze-spindle kunye ne-impeller e-China yi-35CrMo, i-35CrMoV, i-27Cr2Mo1V, i-12Cr3MoWV, njl njl. I-rotor ye-gas turbine yenziwe ngentsimbi ye-20Cr3MoWV.Ukusebenzisa ukucima kunye nonyango lokufudumala.Kwimibhobho emikhulu efana ne-rotors eyenziweyo kunye ne-impellers, ukuze kunyibilike ngokupheleleyo i-vanadium carbide kunye nokuphucula iplastiki kunye nokuqina, ukunyangwa kwangaphambili okuqhelekileyo kunokwenziwa ngaphambi kokucinywa, okanye inkqubo yonyango lobushushu lwesibini esiqhelekileyo kunye nobushushu singasetyenziswa.
[5] I-1Cr5Mo kunye ne-Cr6SiMo yentsimbi.
Ezi zigaba zimbini zinezona zinto ziphezulu zokudibanisa kwintsimbi ye-pearlitic enganyangeki ukushisa.Banokumelana nobushushu obuhle kunye nokunganyangeki kwe-corrosion kwimidiya ye-petroleum.Zisetyenziswa ngokubanzi ekwenzeni imibhobho kunye neenqanawa zepetroleum distillation izixhobo, ukufudumeza iityhubhu zesithando somlilo kunye noTshintshiselwano lobushushu, njl. njl., Zikwasetyenziswa njengokufa kwesitampu esitshisayo, iimpompo zamafutha, iivalvu, izixhoma kwibhoyila kunye nezinye iindawo.Ngokuqhelekileyo ubushushu bokusetyenziswa bungaphantsi kwama-650 ℃.Ekubeni le ntsimbi iyintsimbi eqinile yomoya, i-weld seam inobunzima obuphezulu kunye neplastiki engafanelekanga, ngoko kufuneka ipholiswe kancinane kwaye ifakwe emva kwe-welding.
Ukuqengqeleka okushushu (ityhubhu yentsimbi ekhutshiweyo engenamthungo): ityhubhu engqukuva → ukufudumeza → ukugqobhoza → ukuqengqeleka okuqengqelekayo okuthathu, ukuqengqeleka okuqhubekayo okanye ukukhutshwa → ukususwa kwetyhubhu → ukulinganisa (okanye ukunciphisa) → ukupholisa → ityhubhu yebhiliti → ukolula → Uvavanyo loxinzelelo lwamanzi (okanye isiphene ubhaqo) → phawula → ugcino.
Umbhobho wentsimbi obandayo ozotyiweyo (oqengqiwe): umbhobho wetyhubhu engqukuva → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuchola → ukuthambisa (iplate yobhedu) → umzobo obandayo ogqithisayo (ukuqengqeleka okubandayo) → ityhubhu yebillet → unyango lobushushu → ukolula → Uvavanyo loxinzelelo lwamanzi (ukubona iziphene) → phawula → ugcino.
