Iindidi kunye nokuSetyenziswa China Cast Carbon Steel
Ithunyelwe nguAdmin
Kukho iintlobo ezininzi zeCarbon Steel ekhoyo ekhoyo kwimarike.Ezi ntsimbi zihlulwe zibe ngamacandelo ahlukeneyo ngokuxhomekeke ekusebenziseni ezijoliswe kuzo.Zihlelwa kwiindidi ezintathu eziphambili, ezifakwe kwi-annealed, eziqhelekileyo kunye nensimbi engenasici.Zinokwahlulwa ngakumbi kwisakhiwo, ukuveliswa koomatshini kunye neentsimbi ze-alloy.Iimpawu zezi zinsimbi zixhomekeke kuhlobo lonyango lokushisa kunye nomxholo wekhabhoni.Ukongeza koko, amaxabiso abo obunzima buxhomekeke kuhlobo lonyango lobushushu.Ukubunjwa kweCarbon Steel kuxhomekeke kumxholo wekhabhoni.Le nto yokudibanisa yeyona nto ibalulekileyo.Ezinye izinto zizixa-mkhondo.Phakathi kwezi zinto kukho i-silicon, i-manganese, kunye nentsimbi.Abo banomxholo ophantsi kwezi zinto babizwa ngokuba yi-low-alloy steels.Iintsimbi zeCarbon ezikumgangatho ophezulu zihlala ziqulathe ngaphezulu kwe-0.5% yekhabhoni.Baziwa ngamandla abo aphezulu, ukuqina, kunye nexabiso eliphantsi.Kukho iindlela ezininzi zokuvavanya amandla kunye nokuqina kweCarbon Steel.Ngokomzekelo, ukuqina kwe-plane-strain fracture kumiselwa yi-SN curve.Ezi datha zingasetyenziswa kwii-equations zoyilo.Ukukhathala, ijika le-SN liyisiseko esisisiseko sobudlelwane phakathi kobomi kunye nokukhathala.Ubomi bayo bunxulumene noxinzelelo olukhulu olusetyenziswayo.Iimvavanyo ze-Constant-amplitude zisetyenziselwa ukufumanisa uvakalelo lwento ukudinwa.Enye indlela yokuvavanya ukomelela kwentsimbi kukuqina kokwaphuka.Kukho iimvavanyo ezininzi zokulinganisa ukuqina, kubandakanywa uvavanyo lwempembelelo ye-Charpy V-notch, uvavanyo lobunzima bokulahla, kunye novavanyo oluguqukayo lokukrazula.Ngaphezu koko, iinkqubo ezikhethekileyo zisetyenziselwa ukuvavanya ukuqina kokuphuka kwenqwelomoya.Ngaphandle koko, ijika le-SN libonelela ngedatha malunga namandla ezinto eziphathekayo.Ijika le-SN libonisa ubudlelwane phakathi kobomi bomzekelo wokukhathala kunye noxinzelelo oluphezulu olusetyenzisiweyo.Kukho iintlobo ezahlukeneyo zeCarbon Steel.Kukho iintsimbi eziphantsi kwekhabhoni kunye nekhabhoni ephezulu.Umahluko phakathi kwabo ulele kwisixa sekhabhoni kwintsimbi.Insimbi ye-carbon ephakathi iqulethe ngaphantsi kweepesenti ze-0.2 zekhabhoni kunye ne-high-carbon steel iqulethe phakathi kwe-0.2% kunye ne-0.5 yeepesenti zekhabhoni.Ukuphakama komxholo wekhabhoni, amandla amakhulu ezinto eziphathekayo.Le yokugqibela isetyenziselwa iimoto.Ukongeza kolu setyenziso lukhankanywe ngasentla, iKhabhoni ephothiweyo iluncedo nakwezinye iinjongo.Iimpawu zomatshini weCarbon steel zinovelwano kakhulu kubushushu.Ngexesha lobushushu obuphezulu, izixhobo zoomatshini ziyancipha kwaye zikhokelela ekungaphumelelini kwangaphambili.Ukongezelela, insimbi ixhomekeke kwi-oxidation, umonakalo we-hydrogen, ukungazinzi kwe-carbide kunye ne-sulphite scaling.Ukuqina kwayo kuncitshiswe kakhulu kumaqondo obushushu aphantsi.Ngoko ke, i-Steel ekhethekileyo yobushushu obuphantsi iyafumaneka ukusombulula ezi ngxaki.Izinto ezixutywayo zandisa ukuqina kwe-carbon steel casting.
- NGAPHAMBILI: IiNzuzo zokuCasa ngeNtsimbi eNgatyiwayo ngokuchanekileyo
- OKULANDELAYO: Indlela yokuba ngumvelisi wesiseko somgangatho ophezulu
