Umehluko phakathi kwensimbi engagqwali nensimbi egoqiwe ebandayo mkhulu kakhulu. Ubukhulu obukhulu bensimbi evamile egoqelwe ngokubanda ngu-8mm. Ngokuvamile, amakhoyili ensimbi agoqwe ashisayo asetshenziswa njengezinto ezingavuthiwe ukuze kukhiqizwe insimbi enhle newusizo egoqelwe ngokubanda. Ikhoyili ngayinye ingafinyelela amathani ayi-13.5. Ngokungafani nensimbi engagqwali, insimbi engagqwali ayinakho ukujiya okucacisiwe, futhi izinto zayo zokusetshenziswa ngokuvamile azigcini nje ngensimbi, kodwa futhi ne-nickel, i-chromium, nama-cones, konke okungezensimbi. Insimbi engagqwali inokumelana nokugqwala okuthile, futhi izakhiwo zamakhemikhali ezijwayelekile ngeke ziyenze igle.

Umehluko:

1. Insimbi engagqwali iwuhlobo lwensimbi, futhi insimbi egoqekayo iwuhlobo lwensimbi.
2. Insimbi engagqwali isho insimbi ekwazi ukumelana nemithombo yemali ebolayo engenamandla njengomoya, isitimu, amanzi, kanye nemithombo yezindaba egqwala ngamakhemikhali njenge-asidi, i-alkali, nosawoti. Ibizwa nangokuthi insimbi engagqwali engamelana ne-asidi. Ezisetshenziswa ezingokoqobo, insimbi imelana nendawo yokugqwala ebuthaka ngokuvamile ibizwa ngokuthi insimbi engagqwali, futhi insimbi imelana nokugqwala okuphakathi kwamakhemikhali ibizwa ngokuthi insimbi engamelana ne-asidi. Ngenxa yomehluko ekwakhiweni kwamakhemikhali phakathi kwalokhu kokubili, eyokuqala ayimelani ngempela nokugqwala kwemithombo yamakhemikhali, kuyilapho yakamuva ngokuvamile ayinabala.

Ukumelana nokugqwala kwensimbi engagqwali kuncike ezintweni ze-alloying eziqukethwe ensimbi. Izakhi eziyisisekelo ze-alloying yensimbi engagqwali zifaka i-nickel, iplatinum, i-chromium, i-nickel, ithusi, i-nitrogen, njll., ukuze kuhlangatshezwane nezidingo zokusetshenziswa okuhlukahlukene kwesakhiwo nokusebenza kwensimbi engagqwali. Insimbi engagqwali igqwala kalula ngama-ion e-chloride, ngoba i-chromium, i-nickel, ne-chlorine kuyizinto ze-isotopic, ezizoshintshaniswa futhi zihlanganiswe ukwenza ukugqwala kwensimbi engagqwali.

Insimbi egoqwe ngamakhaza yenziwe ngamakhoyili ashisayo, agingqiwe ekamelweni lokushisa ngaphansi kwezinga lokushisa le-recrystallization, okuhlanganisa amapuleti namakhoyili. Izigayo eziningi zensimbi zasekhaya ezifana ne-Baosteel, Wuhan Iron and Steel, kanye ne-Anshan Iron and Steel zingazikhiqiza. Phakathi kwazo, lezo ezilethwa ngamashidi zibizwa ngokuthi amapuleti ensimbi, abizwa nangokuthi amapuleti ebhokisi noma amapuleti ayisicaba; lawo alethwa ngamakhoyili abizwa ngokuthi ama-steel plate, abizwa nangokuthi ama-coil plate.

3. Insimbi evamile egoqelwe ngokubanda: ibhekisela emikhiqizweni egoqelwe kumapuleti esigabeni esivamile se-carbon steel (ngokuvamile esongwa sibe ikhoyili), kanti eminye ihlanganisa imigoqo, izintambo, njll.

Insimbi engagqwali isho insimbi ye-alloy engezwe ngezinto ezifana ne-Cr ne-Ni. Uhlobo lwensimbi olumele luyinsimbi engagqwali engu-304. Insimbi engagqwali futhi ihlukanisa amapuleti, imigoqo, amaphrofayili, izintambo, njll.
4. Insimbi egoqelwe ngokubanda: Inamandla amakhulu, kodwa ayiqini kahle futhi iyashisela, iqinile uma iqhathaniswa, ishwabana, futhi igqamile.

Insimbi engagqwali: indawo enhle kanye namathuba okusebenzisa ahlukahlukene, ukumelana nokugqwala okuhle, ukuhlala isikhathi eside kunensimbi evamile, ukumelana nokugqwala okuhle namandla aphezulu, ngakho-ke amathuba okusebenzisa amapuleti amancane aphakeme, ukumelana ne-oxidation okushisa aphezulu namandla aphezulu, ngakho-ke ingakwazi ukumelana nomlilo kanye nenqubo ekamelweni lokushisa, okungukuthi, kulula Ngoba ukucutshungulwa kwepulasitiki akudingi ukwelashwa okungaphezulu, kulula, kuhle, kulula ukuyigcina futhi kulula ukuyigcina futhi ihlanzekile.

Siyazi ukuthi insimbi engagqwali iwuhlobo lwensimbi, futhi kunezinhlobo eziningi kulesi sigaba, njengensimbi engagqwali ye-ferritic. Insimbi engagqwali ye-Austenitic, imvula eyenza insimbi engagqwali ibe lukhuni, njll. kanye nensimbi egoqwe ngokubanda iyinsimbi egoqelwe ngokubanda, enohlobo lwayo, ngokungafani negama elivamile elithi “insimbi engagqwali”. Lapho sithenga insimbi engagqwali, singathenga insimbi engagqwali ehlukene ngokwezidingo zethu, futhi ukuthenga insimbi egoqwe ngokubanda kuwukuthenga okuhlosiwe. Izinto esizithengayo ziyinsimbi egoqwe ngokubanda kuphela, okumele ihlukaniswe ngokucacile.
