321 Iityhubhu zeNsimbi eNgatyiwayo

I-321 ipayipi yensimbi engenasici yipayipi yensimbi eyenziwe nge-321 yensimbi engenasici.

1:321 umbhobho wensimbi engenasici.Umbhobho wentsimbi ongenamthungo (GB14976-2002) usetyenziselwa ukwenza imibhobho yomphunga eshushu kakhulu, imibhobho yamanzi abilayo kunye neebhoyila zelocomotive zezakhiwo ezahlukeneyo kwiibhoyila ezinoxinzelelo oluphantsi naphakathi, imibhobho yomsi emikhulu, imibhobho emincinci yomsi kunye nemibhobho yezitena ze-arch.Umgangatho ophezulu wekhabhoni yesakhiwo sentsimbi eshushu-eshushu kunye nebandayo (eqengqelekayo) imibhobho yentsimbi engenamthungo.

2: 321 umbhobho wensimbi engenasici: ubukhulu becala isetyenziselwa ukwenza umgangatho ophezulu wekhabhoni yensimbi yesakhiwo, i-alloy structural steel kunye nentsimbi engenakunqanda ukushisa kwensimbi engenamthungo kwimibhobho yebhoyila enoxinzelelo oluphezulu nangaphezulu.Le mibhobho yebhoyila ihlala ibonakaliswe kwiqondo lokushisa eliphezulu kunye noxinzelelo oluphezulu.Umsebenzi, umbhobho uya kuphinda udibanise kwaye udle phantsi kwesenzo segesi ephezulu yokushisa kunye nomphunga wamanzi, ngoko ke umbhobho wentsimbi kufuneka ube namandla aphezulu, ukuxhatshazwa kwe-oxidation ephezulu, kunye nokuzinza okuhle kombutho.

3: I-321 ityhubhu yensimbi engenasici ithatha inombolo yentsimbi: 304321 316 317 310, njl.

4: I-alloy imibhobho yensimbi yesakhiwo kunye namabakala ensimbi ye-15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, njl.;i-stainless kunye ne-heat-resistant-resistant steel 1Cr18Ni9, 1Cr18Ni11Nb high-pressure boiler tubes, ngaphezu kokuqinisekisa ukubunjwa kweekhemikhali kunye neempawu zomatshini, kufuneka zinyanzeliswe ngamanzi enye enye Kuvavanyo, uvavanyo oluvuthayo kunye nokulinganisa luyafuneka.

I-5: Iipayipi ze-321 zensimbi ezingenasici zihanjiswa kwimeko yokushisa ukushisa.Ukongezelela, kukho iimfuno ezithile ze-microstructure, ubukhulu bengqolowa kunye ne-decarburization layer yombhobho wensimbi ogqityiweyo.Imibhobho yentsimbi engenamthungo yokugrumba ijoloji kunye nolawulo lokwemba ioli;izixhobo zokugrumba zisetyenziselwa ukufumanisa ubume bamatye angaphantsi komhlaba, amanzi aphantsi komhlaba, i-oyile, igesi yendalo kunye nemithombo yezimbiwa.

Ukusetyenziswa kwe-oyile kunye negesi yendalo ayinakwahlulwa kwimingxuma yokugrumba.Imibhobho yentsimbi engenamthungo yokugrumba i-oyile yokulawula ukugrumba ijoloji zezona zixhobo ziphambili zokomba, ingakumbi kubandakanywa umbhobho ongundoqo wangaphandle, undoqo wombhobho ongaphakathi, i-casing, umbhobho wokomba njalo njalo.Ngenxa yokuba umbhobho wokomba kufuneka ungene nzulu kubunzulu bokwakheka kweekhilomitha eziliqela, umbhobho wealloyi oyi-1cr5mo.

6: Iimeko zokusebenza zinzima kakhulu.Umbhobho wokugrumba uphantsi koxinzelelo olufana noxinzelelo, ukucinezelwa, ukugoba, ukushukuma kunye nomthwalo wempembelelo ongalungelelananga, kwaye ukwaphantsi kodaka namatye.Ngoko ke, umbhobho kufuneka ube namandla okwaneleyo, ukuqina, ukumelana nokugqoka kunye nokuqina kweMpembelelo, intsimbi esetyenziselwa umbhobho wensimbi imelwe yi "DZ" (isiqalo se-geological Chinese Pinyin) kunye nenombolo enye yokumela inqaku lemveliso yentsimbi.Amanqanaba ensimbi asetyenziswa ngokuqhelekileyo yi-45MnB kunye ne-50Mn ye-DZ45;40Mn2 kunye ne-40Mn2Si ye-DZ50;I-40Mn2Mo kunye ne-40MnVB ye-DZ55;40MnMoB ye-DZ60, 27MnMoVB ye-DZ65.Imibhobho yentsimbi ihanjiswa kwimeko yokushisa.
