Kungani izinto ze-Stainless Steel kunzima ukuzicubungula?

Insimbi engagqwali,  ekuqaleni eyayibizwa nge-rustless steel, iyinoma iyiphi yeqembu lama-alloy ayoniwe aqukethe okungenani okungenani u-11% we-chromium, ukwakheka okuvimbela i-ayoni ukuthi ingagqwali futhi ihlinzeke ngezinto ezikwazi ukumelana nokushisa.

Uma kuqhathaniswa nezinsimbi "ezithambile" ezifana ne-aluminium, insimbi engagqwali inzima kakhulu ukuyifaka umshini. Lokhu kungenxa yokuthi insimbi engagqwali iyinsimbi yengxubevange enamandla aphezulu kanye nepulasitiki enhle. Phakathi nenqubo yokwenza imishini, impahla izoba nzima futhi ikhiqize ukushisa okuningi. Lokhu kuholela ekugqokeni kwamathuluzi okusika ngokushesha. Nazi izizathu eziyisi-6 eziyinhloko:

1. Amandla okushisa aphezulu kanye nokuthambekela kokuqina komsebenzi

Uma kuqhathaniswa nensimbi evamile, insimbi engagqwali inamandla aphakathi nobulukhuni. Kodwa-ke, iqukethe inani elikhulu lezinto ezifana ne-Cr, i-Ni, ne-Mn, futhi ine-plasticity enhle nokuqina, amandla okushisa aphezulu, kanye nokuthambekela kokuqina komsebenzi ophezulu okwenza kube nzima ukusika. Ukwengeza, ku-austenitic insimbi engagqwali ngesikhathi sokusika, enye i-carbide iyancipha ngaphakathi, okwandisa umphumela wokuklwebheka kumsiki.

2.Kudingeka amandla amakhulu okusika

Insimbi engagqwali ine-deformation enkulu yepulasitiki ngesikhathi sokusika, ikakhulukazi i-austenitic stainless steel (i-elongation idlula izikhathi ezingu-1.5 kune-45 steel), okwandisa amandla okusika.

I-3.Chip ne-tool bonding phenomenon ivamile

Kulula ukwenza unqenqema olwakhiwe ngesikhathi sokusika, oluthinta ukuhwaqeka kwendawo yomshini futhi kubangele kalula ingaphezulu lethuluzi ukuthi lixebuke.

4. I-chip ilula ukugoqa nokuphuka

Kwabasiki bengqephu abavaliwe nabavaleke kancane, ukuvala ama-chip kulula ukwenzeka, okuholela ekwandeni kokuqina kwendawo kanye nokuqoshwa kwamathuluzi.

5. I-coefficient enkulu yokunwetshwa komugqa

Cishe isikhathi esisodwa nesigamu kune-coefficient yomugqa yokwandisa ye-carbon steel. Ngaphansi kwesenzo sokusika izinga lokushisa, i-workpiece ijwayele ukuguqulwa kwe-thermal futhi ithinta ukunemba kwe-dimensional.

6. Small conductivity ezishisayo

Ngokuvamile, cishe i-1/4~1/2 ye-thermal conductivity yensimbi ye-carbon steel. Izinga lokushisa lokusika liphezulu futhi ithuluzi ligqoka ngokushesha.

Indlela yokwenza insimbi engagqwali?

Ngokusekelwe ekusebenzeni kwethu nolwazi, sikholwa ukuthi le mihlahlandlela elandelayo kufanele ilandelwe uma kwenziwa imishini yensimbi engagqwali:

1.Ukwelashwa kokushisa ngaphambi komshini, Inqubo yokwelapha ukushisa ingashintsha ubulukhuni bensimbi engagqwali, ikwenze kube lula ukuyifaka.

2.Ukuthambisa okuhle kakhulu, Uketshezi olupholile lokuthambisa lungasusa ukushisa okuningi futhi lugcobe indawo yomkhiqizo ngesikhathi esifanayo. Ngokuvamile sisebenzisa okokugcoba okuxubile okuhlanganiswe ne-nitrogen tetrafluoride namafutha enjini. Ukuzijwayeza kufakazele ukuthi le nto yokuthambisa ifaneleka kakhulu ekwenzeni izingxenye zensimbi engagqwali ezinezindawo ezibushelelezi.

3.Sebenzisa amathuluzi okusika ekhwalithi ephezulu ukuthola izingxenye ezibushelelezi nokubekezelelana okuncane kuyilapho unciphisa isikhathi sokushintsha amathuluzi.

4.Ijubane lokusika eliphansi. Ukukhetha isivinini esiphansi sokusika kunganciphisa ukukhiqizwa kokushisa futhi kusize ukuphulwa kwe-chip.

Isiphetho

Sekukonke, insimbi engagqwali ingenye yezinto ezinzima kakhulu emshinini. Uma isitolo somshini sikwazi umshini we-aluminium, ithusi, ne-carbon steel kahle kakhulu, lokhu akusho ukuthi bangakwazi nomshini wensimbi engagqwali kahle kakhulu.
