IYINI INKINGA?

Insimbi engagqwali iyinsimbi ne-chromium alloy. Nakuba i-stainless kumele iqukathe okungenani u-10.5% we-chromium, izingxenye eziqondile nezilinganiso zizohluka ngokuya ngebanga eliceliwe kanye nokusetshenziswa okuhlosiwe kwensimbi.

YENZA KANJANI IZINSIMBI

Inqubo eqondile yebanga lensimbi engagqwali izohluka ezinyathelweni zakamuva. Ukuthi izinga lensimbi elakheka, lisebenza futhi liqedwa kanjani lidlala indima ebalulekile ekunqumeni ukuthi libukeka kanjani futhi lenze kanjani.

Ngaphambi kokuthi udale umkhiqizo wensimbi olethwayo, kufanele uqale udale ingxubevange encibilikisiwe.

Ngenxa yalokhu amamaki amaningi ensimbi ahlanganyela izinyathelo ezivamile zokuqala.

Isinyathelo 1: Ukuncibilika

Ukukhiqiza insimbi engagqwali kuqala ngokuncibilika kwezinsimbi ezilahliwe nezithasiselo esithandweni somlilo se-arc kagesi (EAF). Isebenzisa ama-electrode anamandla amakhulu, i-EAF ishisisa izinsimbi phakathi namahora amaningi ukuze yakhe ingxube encibilikisiwe, ewuketshezi.

Njengoba insimbi engagqwali igaywa kabusha ngo-100%, ama-oda amaningi angenasici aqukethe cishe u-60% wensimbi egaywe kabusha. Lokhu kusiza hhayi kuphela ukulawula izindleko kodwa ukunciphisa umthelela kwemvelo.

Amazinga okushisa aqondile azohluka ngokuya ngebanga lensimbi elakhiwe.

Isinyathelo sesi-2: Ukususa Okuqukethwe Kwekhabhoni

Ikhabhoni isiza ekwandiseni ubulukhuni namandla ensimbi. Kodwa-ke, i-carbon eningi ingadala izinkinga-ezifana nemvula ye-carbide ngesikhathi sokushisela.

Ngaphambi kokuphonsa insimbi engagqwali encibilikisiwe, ukulinganisa nokunciphisa okuqukethwe kwekhabhoni kuye ezingeni elifanele kubalulekile.

Kunezindlela ezimbili zokulawula okuqukethwe kwekhabhoni.

Eyokuqala nge-Argon Oxygen Decarburization (AOD). Ukujova ingxube yegesi ye-argon ensimbi encibilikisiwe kunciphisa okuqukethwe kwekhabhoni ngokulahleka okuncane kwezinye izakhi ezibalulekile.

Enye indlela esetshenzisiwe iVacuum Oxygen Decarburization (VOD). Ngale ndlela, insimbi encibilikisiwe idluliselwa kwelinye igumbi lapho kufakwa umoya-mpilo ensimbi kuyilapho kufakwa ukushisa. Ivacuum ibe isisusa amagesi aphumayo egumbini, okuqhubeka nokunciphisa okuqukethwe kwekhabhoni.

Zombili izindlela zinikeza ukulawula okunembile kokuqukethwe kwekhabhoni ukuze kuqinisekiswe ingxube efanele kanye nezici eziqondile emkhiqizweni wokugcina wensimbi engagqwali.

Isinyathelo sesi-3: Ukushuna

Ngemuva kokunciphisa i-carbon, ukulinganisa kokugcina kanye ne-homogenization yokushisa kanye ne-chemistry kwenzeka. Lokhu kuqinisekisa ukuthi insimbi ihlangabezana nezimfuneko zebanga elihlosiwe nokuthi ukwakheka kwensimbi kuyahambisana kuyo yonke inqwaba.

Amasampula ayahlolwa futhi ahlaziywe. Ukulungiswa bese kwenziwa kuze kube yilapho ingxube ifinyelela izinga elidingekayo.

Isinyathelo sesi-4: Ukwakha noma Ukusakaza

Ngensimbi encibilikisiwe edaliwe, isisekelo kufanele manje sakhe isimo sakudala esisetshenziselwa ukupholisa nokusebenza kwensimbi. Ukuma okuqondile nobukhulu kuzoncika kumkhiqizo wokugcina.
