Ibha Yokubumba Insimbi Engagqwali Eqinisa Ubudala
Incazelo emfushane:
Ukuqina kokuguga, okwaziwa nangokuthi ukuqina kwemvula, kuyinqubo yokwelapha ukushisa ethuthukisa amandla nokuqina kwezinsimbi ezithile, okuhlanganisa nensimbi engagqwali. Umgomo wokuqina kokuguga ukubangela ukuminyana kwezinhlayiya ezincane ngaphakathi kwe-matrix yensimbi engagqwali, okuqinisa izinto.
Ibha Yokubumba Insimbi Engagqwali Eqinisa Ubudala:
Ama-Forging ayizingxenye zensimbi ezakhiwe ngenqubo yokufaka, lapho izinto zifudunyezwa khona bese zishaywa ngesando noma zicindezelwe zibe uhlobo olufunwayo. Ama-Forging ensimbi engagqwali avame ukukhethwa ngenxa yokumelana kwawo nokugqwala, amandla, nokuqina, okwenza afanelekele izinhlelo zokusebenza ezahlukahlukene, kufaka phakathi izindiza, uwoyela negesi, nokuningi. I-Forging efana nebha uhlobo oluthile lwensimbi eyenziwe ngebha evame ukuba nesimo eside, esiqondile, esifana nebha noma induku. Amabha avame ukusetshenziswa ezinhlotsheni lapho kudingeka khona ubude bezinto obuqhubekayo, obuqondile, njengasekwakheni izakhiwo noma njengezinto zokusetshenziswa zokucubungula okwengeziwe.

Kuyini Ukuqinisa Insimbi Engagqwali Yemvula?
Insimbi engagqwali eqinisa imvula, evame ukubizwa ngokuthi "insimbi engagqwali ye-PH," uhlobo lwensimbi engagqwali oludlula enkambisweni ebizwa ngokuthi ukuqina kwemvula noma ukuqina kokuguga. Le nqubo ithuthukisa izakhiwo zemishini zento, ikakhulukazi amandla ayo nokuqina kwayo. Insimbi engagqwali eqinisa imvula evame kakhulu yi17-4 PH(Ibanga le-ASTM A705 630), kodwa amanye amazinga, njenge-15-5 PH kanye ne-13-8 PH, nawo awela kulesi sigaba. Izinsimbi ezingagqwali eziqinisa imvula zivame ukuhlanganiswa nezinto ezifana ne-chromium, i-nickel, ithusi, futhi ngezinye izikhathi i-aluminium. Ukwengezwa kwalezi zinto ezihlanganisayo kukhuthaza ukwakheka kwama-precipitate ngesikhathi senqubo yokwelashwa kokushisa.
Imvula yensimbi engagqwali iqiniswa kanjani?
Insimbi engagqwali yokuqinisa ukuguga ihilela inqubo yezinyathelo ezintathu. Ekuqaleni, izinto zidlula ekwelashweni kwesisombululo sokushisa okuphezulu, lapho ama-athomu ancibilikayo encibilika khona, akha isisombululo sesigaba esisodwa. Lokhu kuholela ekwakhekeni kwama-nuclei amaningi amancane noma "izindawo" ensimbi. Ngemva kwalokho, ukupholisa okusheshayo kwenzeka ngale komkhawulo wokuncibilika, okudala isisombululo esiqinile esiqinile esimweni esizinzile. Esinyathelweni sokugcina, isisombululo esiqinile sishiswa sibe yizinga lokushisa eliphakathi, okubangela imvula. Izinto zibe sezigcinwa kulesi simo kuze kube yilapho ziqina. Ukuqina kokuguga ngempumelelo kudinga ukuthi ukwakheka kwe-alloy kube ngaphakathi komkhawulo wokuncibilika, okuqinisekisa ukusebenza kahle kwenqubo.
Yiziphi izinhlobo zensimbi eqinile evuthulukayo?
Izinsimbi eziqinisa imvula ziza ngezinhlobo ezahlukene, ngayinye iklanyelwe ukuhlangabezana nezidingo ezithile zokusebenza kanye nokusetshenziswa. Izinhlobo ezivamile zifaka phakathi i-17-4 PH, i-15-5 PH, i-13-8 PH, i-17-7 PH, i-A-286, i-Custom 450, i-Custom 630 (17-4 PHMod), kanye neCarpenter Custom 455. Lezi zinsimbi zinikeza inhlanganisela yamandla aphezulu, ukumelana nokugqwala, kanye nobunzima, okwenza zifaneleke ezimbonini ezahlukahlukene ezifana nezindiza, izimoto, ezokwelapha, kanye nokucubungula amakhemikhali. Ukukhetha insimbi eqinisa imvula kuncike ezicini ezifana nendawo yokusetshenziswa, ukusebenza kwezinto, kanye nemininingwane yokukhiqiza.
Ukupakisha:
1. Ukupakisha kubaluleke kakhulu ikakhulukazi uma kuthunyelwa kwamanye amazwe lapho imithwalo idlula khona ngemigudu eyahlukene ukuze ifike endaweni yokugcina, ngakho-ke sikhathalela kakhulu ukupakisha.
2. I-Saky Steel ipakisha izimpahla zethu ngezindlela eziningi ngokusekelwe emikhiqizweni. Sipakisha imikhiqizo yethu ngezindlela eziningi, njengokuthi,
