Amashidi ensimbi engagqwali namakhoyili kuyizinto ezibalulekile ezisetshenziswa ezimbonini eziningi ngenxa yezakhiwo zazo ezihlukile, njengokumelana nokugqwala, amandla, kanye nokuguquguquka. Njengoba izimboni, abasabalalisi, nozakwethu besiteshi behlola imakethe yemikhiqizo yensimbi engagqwali, ukuqonda izinhlobo ezahlukene kanye nokusetshenziswa kwamashidi ensimbi engagqwali namakhoyili kubaluleka. Kungakhathaliseki ukuthi asetshenziswa ekwakheni, ezintweni zezokwelapha, noma ekucubunguleni ukudla, amashidi ensimbi engagqwali ayizingxenye ezibalulekile ezihlangabezana nezindinganiso eziqinile zomkhakha.
Lesi sihloko sinikeza ukuhlaziywa okuphelele kwamashidi namakhoyili ensimbi engagqwali, echaza ukwakheka kwawo, inqubo yokukhiqiza, kanye nohlu olubanzi lwezinhlelo zokusebenza. Iphinde ihlole izinzuzo zamafekthri, abasabalalisi, nabadayisi abafuna izinto ezithembekile ngezinjongo ezehlukene zezimboni nezentengiso. Kulabo abathanda ukwazi okwengeziwe ngemikhiqizo yekhoyili yensimbi engagqwali, ukuvakashela amakhasi afana nala Ishidi Lekhoyili Lensimbi Engagqwali linganikeza imininingwane eyengeziwe.
Ukuqonda Amashidi Ensimbi Engagqwali namakhoyili
Amashidi ensimbi engagqwali ayizicucu zensimbi eziyisicaba ngokuvamile ezinokuqukethwe okuphezulu kwe-chromium, okuwanika izici zawo ezihlukile zokulwa nokugqwala. Lawa mashidi angakhiqizwa ngamamaki ahlukahlukene, ubukhulu, kanye nokuqedwa kwendawo, kuye ngokuthi asetshenziswa kanjani. Okwamanje, amakhoyili ensimbi engagqwali empeleni angamashidi asongwa abe amakhoyili ukuze kube lula ukuhamba nokuwagcina. Kokubili amashidi namakhoyili angagoqwa ashise noma agoqelwe ngokubanda, inqubo ngayinye inikeza izinzuzo ezihlukile kuye ngokusetshenziswa kokugcina.
Izinhlobo zamashidi ensimbi engagqwali namakhoyili
Insimbi engagqwali ihlukaniswa yaba izinhlobo eziningana ngokusekelwe esakhiweni sayo sekristalu kanye nezakhi ze-alloying. Izinhlobo ezivame kakhulu zihlanganisa:
I-Austenitic Stainless Steel: Lolu uhlobo oluvame kakhulu, olwaziwa ngokumelana nokugqwala okuhle kakhulu kanye nokubumbeka. Ngokuvamile kufaka phakathi amamaki afana ne-304 kanye ne-316, asetshenziswa kakhulu ekwakheni, ekucubunguleni ukudla, nasezinhlelweni zezokwelapha.
I-Ferritic Stainless Steel: Lolu hlobo lukazibuthe futhi ngokuvamile lubiza kancane kune-austenitic stainless steel. Ivame ukusetshenziswa ezingxenyeni zezimoto kanye nemishini yezimboni.
Insimbi Engagqwali ye-Martensitic: Yaziwa ngamandla ayo nobulukhuni, insimbi engagqwali ye-martensitic isetshenziswa ezinhlelweni ezidinga ukusebenza kwemishini okuphezulu, okufana nemimese nezinjini zomoya.
I-Duplex Stainless Steel: Ukuhlanganisa izakhiwo zazo zombili i-austenitic kanye ne-ferritic stainless steel, amamaki ayi-duplex anikeza amandla aphezulu kanye nokumelana okuhle kakhulu nokugqwala, ikakhulukazi ezindaweni ezinokhahlo.
Izinqubo Zokukhiqiza Zamashidi Ensimbi Engagqwali namakhoyili
Ukwenziwa kwamashidi namakhoyili ensimbi engagqwali kuhilela izinqubo ezimbalwa ezibalulekile, ngayinye ifaka isandla ezintweni zokugcina zomkhiqizo. Izimboni nabasabalalisi kumele baqonde lezi zinqubo ukuze baqinisekise ukuthi bathola izinto ezihlangabezana nezidingo ezithile zemboni.
I-Hot Rolling: Kule nqubo, ama-slabs ensimbi engagqwali ashiselwa emazingeni okushisa aphezulu abese edlula kuma-roller ukuze afinyelele ubukhulu obufunekayo. Ukugoqa okushisayo kulungele ukukhiqiza amashidi namakhoyili aminyene, futhi kunikeza indawo engaphezulu enzima.
I-Cold Rolling: Ngemva kokuginqika okushisayo, insimbi ingaginqika okubandayo ukuze iqhubeke nokunciphisa ukujiya kwayo futhi ithuthukise ikhwalithi yendawo. Ukugoqa okubandayo kunikeza isiphetho esishelelayo kanye nokubekezelelana okuqinile, okuyenza ifanelekele izinhlelo zokusebenza ezinembayo.
I-Annealing: Le nqubo yokwelapha ukushisa isetshenziselwa ukukhulula izingcindezi nokuthuthukisa i-ductility yensimbi. Ukufakwa kwe-anneal kubaluleke kakhulu emikhiqizweni egoqelwe ebandayo okungenzeka ukuthi ithuthuke ukuqina komsebenzi ngesikhathi sokugoqa.
I-Pickling: Ngemva kokugoqa okushisayo, insimbi ingase ibe nongqimba lwesikali se-oxide, esidinga ukususwa ngenqubo yokukhetha. I-Pickling ihilela ukucwilisa insimbi kwisisombululo se-asidi ukuhlanza indawo.
Ukuqeda: Isinyathelo sokugcina seshidi lensimbi engagqwali kanye nokukhiqizwa kwamakhoyili siyaqedwa, okungahlanganisa ukupholisha, ukunamathisa, noma ukuthumela umbhalo ukuze kuzuzwe ubuhle obufunekayo kanye nezakhiwo zokusebenza.
Izicelo zamashidi ensimbi engagqwali namakhoyili
Ukuhlukahluka kwamashidi namakhoyili ensimbi kuwenza asebenze ezimbonini eziningi. Ikhono labo lokumelana nokugqwala, ukumelana namazinga okushisa aphezulu, nokugcina ubuqotho besakhiwo kubenza babaluleke kakhulu emikhakheni efana neyokwakha, ukucubungula ukudla, imishini yezokwelapha, kanye nokukhiqizwa kwezimoto.
1. Imboni Yezokwakha
