Ubushushu-intsimbi ekwaziyo ukumelana nobushushu sisikhongozeli esiphezulu-seqondo lobushushu esenziwe ngobushushu{2}}ngentsimbi ekwaziyo ukumelana nobushushu (intsimbi yealloyi egcina ukomelela kwayo, ukuxhathisa kunye nokuzinza kweekhemikhali kumaqondo obushushu aphezulu). Ubushushu -intsimbi ekwaziyo ukumelana nobushushu ihlelwa ibe yintsimbi ye-antioxidant (ekwaziyo ukumelana nobushushu obuphezulu-i-oxidation yobushushu) kunye nobushushu{6}}intsimbi yamandla (imelana nokunyuka{7}}kubushushu obuphezulu), kwaye yenza "isiseko sesiseko" sobushushu{8}}esigayiweyo sentsimbi ekwaziyo ukumelana nobushushu. Ezi zixhobo zinokugcina uzinzo lwesakhiwo ixesha elide kumaqondo obushushu aphezulu (njengakwiziko loshishino, oomatshini bamandla, njl.njl.), ukuthintela ukuthotywa kokusebenza okubangelwa{11}}kubushushu obuphezulu kunye ne-oxidation.
IiNkcazo zeeMveliso
Ubushushu-Izikhonkwane zentsimbi ezinganyangekiyo zisetyenziswa kakhulu ekwenzeni amacandelo phantsi{1}}kweemeko zobushushu obuphezulu. Iimeko eziqhelekileyo ziquka:
- Amandla naMandla:{0}}amalungu obushushu obuphezulu besixhobo esinje ngeebhoyila kunye nee turbines zerhasi;
- Amaziko oShishino:{0}}izixhobo ezikwaziyo ukumelana nobushushu kwimizi-mveliso eyahlukeneyo;
- I-aerospace:{0}}ubushushu obuphezulu bezakhi ze-injini zenqwelomoya kunye neziphekepheke;
- Petrochemicals:{0}}izixhobo ezikwaziyo ukumelana nobushushu ezifana{1}}nezixhobo zobushushu obuphezulu kunye nezitshintshisi zobushushu.
Ingqiqo yobuGcisa: iipropati zeMathiriyeli zixhasa{0}}usetyenziso lobushushu obuphezulu
"Ukuxhathisa ubushushu" kobushushu -kwimibhobho yentsimbi enganyangekiyo ivela kumandla ezinto ezizingisayo ({1}}ixesha elide lokuthwala umthamo) kumaqondo obushushu aphezulu, ukuxhathisa kwawo ekurhubuluzeni (ukumelana noguquko olucothayo kumaqondo obushushu aphezulu), kunye nokuzinza kweekhemikhali (ukumelana ne-oxidation ephezulu{2}}nobushushu kunye nokubola). Ezi mpawu zibenza bakwazi ukusebenza njengezikhongozeli ezizinzileyo kwimveliso yemizi-mveliso, zibonelela ngemeko-bume ezinzileyo yokunyibilika kobushushu obuphezulu -, ukusabela, njl., kunye nokuqinisekisa ukuqhubeka kwenkqubo kunye nomgangatho wemveliso.
Intsimbi enganyangekiyo kwicrucible yentsimbi yenziwe{1}}nobushushu obuphezulu njengemathiriyeli engundoqo. Ngempembelelo ye-synergistic yezinto ze-alloy (ezifana ne-chromium, i-nickel, i-silicon, i-manganese, njl.), ifezekisa ukuxhathisa okuphezulu{4}} kobushushu, ukuxhathisa i-oxidation kunye nozinzo lwesakhiwo. Ngentsimbi njengesiseko semathiriyeli, yongeza izinto ezinje ngechromium kunye nenickel, ibhalansisa iindleko kunye nokusebenza kwaye ilungele iimeko eziphakathi-zobushushu ({7}} isidanga ):
Cr{0}Mo series ubushushu{1}}intsimbi exhathisayo
Ibakala lommeli: 1Cr5Mo, 1Cr9Mo (i-American standard T91/P91)
Iimpawu zokuqulunqa: Iqulethe i-5% - 9% Cr, 0.5% - 1% Mo, kunye nexabiso elincinci le-V kunye ne-Nb yokomeleza
Ukusebenza: Ukumelana ne-oxidation ephakathi, amandla alungileyo e-thermal, kunye nexabiso eliphantsi
Usetyenziso:{0}}Iinqanawa zokusabela ubushushu obuphezulu kushishino lwepetrochemical, imibhobho yebhoyila kwizikhululo zamandla
Cr-Ni chwetheza ubushushu beaustenitic{1}}intsimbi exhathisayo
Ibakala elimeleyo: 304 (0Cr18Ni9), 310S (0Cr25Ni20)
Iimpawu zokuqulunqa: Cr 18% - 25%, Ni 9% - 20%, ukwenza isakhiwo esizinzileyo se-austenitic
Iipropathi: Ukumelana namaqondo obushushu ukusuka kwi-800 ukuya kwi-1100 degree, ukuxhathisa okugqwesileyo kwe-oxidation, iplastiki elungileyo
Usetyenziso: Ukulungiswa kokutya, izixhobo zonyango,{0}}amaqokobhe eziko lobushushu obuphezulu ({1}}ezinganyibiliki kakhulu iimeko zokusebenza)
