YINTONI INKINGA ENGENZIMA?
Intsimbi engatyiwayo yintsimbi kunye nealloyi yechromium. Nangona i-stainless kufuneka iqulethe ubuncinane i-10.5% ye-chromium, amacandelo achanekileyo kunye nemilinganiselo iya kuhluka ngokusekelwe kwibakala eliceliwe kunye nokusetyenziswa okujoliswe kuyo kwentsimbi.
INDLELA YEZINTSIMBI EZIYI-Stainless
Inkqubo echanekileyo yebakala lensimbi engenasici iya kuhluka kwizigaba ezilandelayo. Indlela ibakala letsimbi elibunjwe ngayo, elisebenza kwaye ligqityiwe lidlala indima ebalulekileyo ekunqumeni ukuba libukeka njani kwaye lenze njani.
Ngaphambi kokuba wenze imveliso yentsimbi ehanjiswayo, kufuneka uqale wenze i-alloy etyhidiweyo.
Ngenxa yoku, amabakala amaninzi entsimbi abelana ngamanyathelo okuqala aqhelekileyo.
Inyathelo 1: Ukunyibilika
Ukuvelisa intsimbi engenastainless iqala ngokunyibilika kwentsimbi ezilahliweyo kunye nezongezo kwiziko lombane le-arc (EAF). Isebenzisa i-electrode ezinamandla aphezulu, i-EAF ifudumeza iintsimbi kwisithuba seeyure ezininzi ukwenza umxube onyibilikisiweyo, wolwelo.
Njengoko insimbi engenasici i-100% inokuphinda isetyenziswe, ii-odolo ezininzi ezingenastainless ziqulathe ukuya kuthi ga kwi-60% yentsimbi esetyenzisiweyo. Oku kunceda ukulawula iindleko kuphela kodwa ukunciphisa impembelelo yokusingqongileyo.
Amaqondo obushushu achanekileyo aya kuhluka ngokusekelwe kwibakala lentsimbi eyenziwe.
Inyathelo 2: Ukususa umxholo weCarbon
Ikhabhoni inceda ukonyusa ubulukhuni kunye nokomelela kwentsimbi. Nangona kunjalo, i-carbon eninzi inokudala iingxaki-ezifana nemvula ye-carbide ngexesha le-welding.
Ngaphambi kokuphosa intsimbi etyhidiweyo, ukulinganisa kunye nokunciphisa umxholo wekhabhoni ukuya kwinqanaba elifanelekileyo kubalulekile.
Kukho iindlela ezimbini zokulawula umxholo wekhabhoni.
Eyokuqala ngeArgon Oxygen Decarburization (AOD). Ukutofa umxube wegesi ye-argon kwintsimbi etyhidiweyo kunciphisa umxholo wekhabhoni kunye nokulahlekelwa okuncinci kwezinye izinto ezibalulekileyo.
Enye indlela esetyenziswayo yiVacuum Oxygen Decarburization (VOD). Kule ndlela, insimbi etyhidiweyo idluliselwa kwelinye igumbi apho i-oksijini ifakwe kwintsimbi ngelixa kusetyenziswa ukushisa. Ivacuum emva koko isusa iigesi eziphumayo kwigumbi, inciphisa ngakumbi umxholo wekhabhoni.
Zombini iindlela zinika ulawulo oluchanekileyo lomxholo wekhabhoni ukuqinisekisa umxube ofanelekileyo kunye neempawu ezichanekileyo kwimveliso yokugqibela yensimbi engenasici.
Inyathelo lesi-3: Tuning
Emva kokunciphisa i-carbon, ukulinganisa kokugqibela kunye ne-homogenization yokushisa kunye nekhemistri kwenzeka. Oku kuqinisekisa ukuba isinyithi sihlangabezana neemfuno zebakala elijoliswe kuyo kwaye ukubunjwa kwensimbi kuhambelana kuyo yonke ibhetshi.
Iisampulu ziyavavanywa kwaye zihlalutywe. Uhlengahlengiso ke lwenziwa de umxube udibane nomgangatho ofunekayo.
Inyathelo lesi-4: Ukwenza okanye ukuCasa
Ngentsimbi etyhidiweyo eyenziwe, isiseko kufuneka ngoku senze imilo yakudala esetyenziselwa ukupholisa nokusebenza kwentsimbi. Ubume obuchanekileyo kunye nemilinganiselo iya kuxhomekeka kwimveliso yokugqibela.
