Uyazi ukuthi yikuphi okungcono, ipuleti lensimbi elijwayelekile laseMelika i-A36 noma i-Q235B?
I-Shandong Kungang Metal Technology Co., Ltd. igxile ekukhiqizeni nasekuthengisweni kwamapuleti ensimbi, futhi sinolwazi olucebile nedumela emakethe.Lapho uthenga amapuleti ensimbi, kuvamile ukuzwa ukuqhathanisa phakathi kwamapuleti ensimbi ajwayelekile aseMelika A36 kanye ne-Q235B.Lezi zinhlobo ezimbili zamapuleti ensimbi zinokuhluka okuthile ekusebenzeni.Sizokunikeza izincazelo ezinemininingwane yokusebenza kwabo ngemibono eminingi futhi sikusize wenze izinqumo ezihlakaniphile zokuthenga.Okokuqala, ake siqhathanise lezi zingcwecwe ezimbili zensimbi ngokwamandla.Amandla okukhiqiza e-American standard steel plate A36 angama-250MPa, futhi amandla e-tensile angu-400-550MPa, kuyilapho amandla okukhiqiza e-Q235B steel plate angu-235MPa, futhi amandla e-tensile angu-375-500MPa.Kusukela kule datha, kungabonakala ukuthi amandla e-American standard steel plate A36 aphakeme kancane kune-Q235B, okwenza ifaneleke kakhulu ukusetshenziswa kumaphrojekthi adinga ukwesekwa kwamandla aphezulu.
Okwesibili, ake siqhathanise ukwakheka kwawo kwamakhemikhali.Ukwakheka kwamakhemikhali kwepuleti lensimbi elijwayelekile laseMelika i-A36 liqukethe okuqukethwe kwekhabhoni (C) okungu-0.25%, okuqukethwe kwesulfure (S) okungu-0.05%, nokuqukethwe kwe-phosphorus (P) okungu-0.04%, kuyilapho ipuleti lensimbi le-Q235B linokuqukethwe kwekhabhoni (C) okungu-0.22 %, okuqukethwe okuncane (S) okungu-0.05%, nokuqukethwe kwe-phosphorus (P) okungu-0.045%.Ngokombono wokwakheka kwamakhemikhali, awukho umehluko omningi phakathi kwalezi zinhlobo ezimbili zamapuleti ensimbi, womabili angawensimbi yesakhiwo esinomthwalo wekhabhoni futhi anokushisela okuhle nokusebenziseka kalula.
Ngaphezu kwalokho, kunomehluko othile wokumelana nokugqwala phakathi kwamapuleti ensimbi ajwayelekile aseMelika i-A36 ne-0235B.Ngenxa yokuqukethwe okuphezulu kwekhabhoni ye-American standard steel plate A36, ijwayele ukugqwala ezindaweni ezinomswakama ophezulu.Ipuleti lensimbi le-Q235B linokumelana nokugqwala okuhle ezindaweni ezijwayelekile.Kumaphrojekthi wobunjiniyela ajwayelekile, ukukhetha ipuleti lensimbi le-Q235B kungavikela kangcono ukwakheka ekugqwaleni.Ngemuva kwalokho, sidinga futhi ukucabangela isici se-weldability.I-American standard steel plate A36 inokushisela okuhle futhi ingaxhunywa kusetshenziswa izindlela ezijwayelekile zokushisela.Kodwa-ke, ipuleti lensimbi le-Q235B linezinkinga ezithile zokushisela ngenxa yokuqukethwe kwayo kwekhabhoni ephansi.Kwamanye amaphrojekthi adinga ikhwalithi ephezulu yokushisela, ukukhetha ipuleti lensimbi elijwayelekile laseMelika i-A36 kungase kuthembeke kakhulu.Sekukonke, kunomehluko othile phakathi kwamapuleti ensimbi ajwayelekile aseMelika i-A36 ne-Q235B ngokwamandla, ukwakheka kwamakhemikhali, ukumelana nokugqwala, kanye nokulahleka.Uma udinga ukwesekwa kwamandla aphezulu kanye nokumelana nokugqwala okungcono, ungakhetha i-American steel plate A36.Uma unezidingo eziphakeme zekhwalithi yokushisela, ungakhetha ipuleti lensimbi le-Q235B.
I-Shandong Kungang Metal Technology Co., Ltd. ihlinzeka ngemikhiqizo yamapuleti ensimbi esezingeni eliphezulu.Siyakwamukela ukubuza noma ukuvakashela iwebhusayithi yethu ukuze uthole ulwazi olwengeziwe.Sithemba ukuthi sizosebenzisana
futhi udale ukukhalipha!
