Ipuleti lensimbi le-A36ingenye yensimbi evamile, ingabe wake wazi ngayo?
Manje ngilandele ohambweni lokutholwa mayelana nensimbi ye-A36!
Ipuleti lensimbi ye-ASTM-A36 iyinsimbi esezingeni elijwayelekile yaseMelika ye-carbon structural ekhiqizwa ngokwezindinganiso ze-ASTM.Ikhoyili yensimbi ye-A36 yokwakheka kwamakhemikhali kanye nezakhiwo zemishini zihambisana nezindinganiso ze-ASTM zaseMelika.Ukugoqa okushisayo kusetshenziswa njengesimo esiyisisekelo sokulethwa, futhi ubukhulu bokukhiqiza buphakathi kuka-2mm no-400mm.Izidingo zobuchwepheshe zamapuleti ensimbi zingabhekisa ezingeni le-A578 American lokuthola amaphutha.Kunamazinga amathathu okuthola amaphutha A, B, C kanye neleveli ye-A435 yokutholwa kwamaphutha.Ukusebenza kwensimbi egoqiwe ye-A36 kuzinzile ukuze kukhiqizwe.Ipuleti lensimbi eligoqiwe le-A36 linezakhiwo ezinhle zokuwumshini, ukusebenza kokushisela kanye nokumelana nokugqwala, futhi lisetshenziswa kabanzi ekwakheni, kumabhuloho, ekwakhiweni kwemishini nakweminye imikhakha.
I-ASTM-A36 iwuhlobo lwensimbi ye-carbon okwakhiwa kwayo kwamakhemikhali ikakhulukazi kwakhiwe i-carbon (C), i-silicon (Si), i-manganese (Mn), i-phosphorus (P), isulfure (S) nezinye izakhi.Phakathi kwabo, i-carbon iyisici esiyinhloko, futhi umsebenzi wayo ukwandisa amandla nobulukhuni bensimbi.I-silicon kanye ne-manganese yizici ze-alloying ezikhulisa amandla nobulukhuni bensimbi.I-Phosphorus nesibabule yizakhi zokungcola.Ukuba khona kwabo kuzonciphisa ukuqina nokumelana nokugqwala kwensimbi, ngakho okuqukethwe kwabo kudinga ukulawulwa ngokuqinile ngesikhathi senqubo yokukhiqiza.

Inqubo yokukhiqiza ipuleti lensimbi i-A36 ngokuyinhloko ihlanganisa ukusakaza okuqhubekayo, ukuginqika okushisayo, ukuginqika okubandayo, ukukhishwa kwensimbi nezinye izinqubo.Okokuqala, izinto zokusetshenziswa zincibilikiswa zibe izinsimbi zensimbi emazingeni okushisa aphezulu, bese ziphonswa ngokuqhubekayo ukuze kutholwe izinsimbi zensimbi.Bese, ingot yensimbi iyashisa igoqwe futhi ibande ukuze kutholwe ipuleti lensimbi elinemininingwane edingekayo.Okokugcina, i-steel plate idonswa ukuze kuqedwe ingcindezi yangaphakathi futhi kuthuthukiswe izici zomshini nokuzinza kwepuleti lensimbi.Ngaphezu kwalokho, ukuze kuthuthukiswe izinga eliphezulu nokunemba kwepuleti lensimbi, izinqubo ezinjengokwenza isicaba, ukuqondisa, nokusika ngokunemba nazo ziyadingeka.Ingakwazi ukukhiqiza ikhoyili yensimbi ye-A36 yensimbi, ipuleti lokuhlola le-A36, ipuleti lensimbi eligoqiwe elingu-A36 njll.
Amapuleti ensimbi e-ASTM-A36 asetshenziswa kabanzi emikhakheni ehlukahlukene yobunjiniyela, njengokwakha, amabhuloho, ukukhiqizwa kwemishini, njll.
Emkhakheni wokwakha, amapuleti ensimbi e-ASTM-A36 asetshenziselwa ukwakha izakhiwo ezahlukahlukene zokwakha, njengezindawo zokuhlala, izakhiwo zamahhovisi, izitolo ezinkulu, njll.
Emkhakheni wamabhuloho, amapuleti ensimbi e-ASTM-A36 asetshenziselwa ukwakha izakhiwo ezinkulu zamabhuloho, njengamabhuloho omgwaqo, amabhuloho wesitimela, njll.
Emkhakheni wokwenziwa kwemishini, amapuleti ensimbi e-ASTM-A36 asetshenziselwa ukwakhiwa kwezingxenye ezihlukene zesakhiwo, njengezimba, ama-cranes, imishini yezolimo, njll.
Ngokuthuthuka komnotho kanye nokusheshisa ukukhula kwedolobha, isidingo samapuleti ensimbi e-A36 ekwakhiweni, amabhuloho neminye imikhakha sizoqhubeka nokwanda.Ngokuzayo, ngokuthuthuka okuqhubekayo kokuqwashisa ngemvelo, amathemba emakethe amapuleti ensimbi e-ASTM-A36 azoba banzi.Emikhakheni efana nezimoto zamandla amasha kanye nokukhiqizwa kwamandla omoya, isidingo samapuleti ensimbi e-ASTM-A36 nawo azoqhubeka nokukhula.Ngaphezu kwalokho, njengoba izwe liqhubeka nokutshala imali ekwakhiweni kwengqalasizinda, isidingo samapuleti ensimbi e-ASTM-A36 ekwakhiweni, amabhuloho neminye imikhakha nawo azoqhubeka nokukhula.Ngakho-ke, ipuleti lensimbi le-ASTM-A36 linamathemba amakethe abanzi kanye nenani eliphakeme lokutshala imali.
Ipuleti lensimbi le-A36 liyipuleti lensimbi le-carbon structural elisetshenziswa kakhulu elinezakhiwo ezinhle kakhulu zemishini, ukusebenza kokushisela kanye nokumelana nokugqwala.
Izinkambu ezisetshenziswayo zihlanganisa ukwakhiwa, amabhuloho, ukukhiqizwa kwemishini neminye imikhakha.
Ngokuzayo, ngokuthuthuka okuqhubekayo kokuqwashisa ngemvelo kanye nokuthuthukiswa kwezimoto ezintsha zamandla, amandla omoya kanye neminye imikhakha, amathemba emakethe amapuleti ensimbi e-ASTM-A36 azoba banzi.
Ngakho-ke, kubatshalizimali, i-ASTM-A36 inenani eliphakeme lokutshala imali.
Ngasikhathi sinye, kubaklami bezakhiwo zobunjiniyela nabakhiqizi, i-ASTM-A36 nayo iyimpahla yekhwalithi ephezulu okufanele ikhethwe.
Ngethemba ukuthi lesi sihloko siwusizo kuwe.
