NIKI CYUMWERU?

Ibyuma bitagira umwanda nicyuma na chromium. Mugihe idafite ingese igomba kuba ifite byibura 10.5% chromium, ibice nyabyo nibipimo bizahinduka bitewe nurwego rwasabwe hamwe nogukoresha ibyuma.

UKO INKINGI ZITANDUKANYE

Inzira nyayo yo kurwego rwibyuma bitagira umwanda bizatandukana mubyiciro bizakurikiraho. Uburyo urwego rwibyuma rukozwe, rukora kandi rwarangiye rufite uruhare runini muguhitamo uko rusa kandi rukora.

Mbere yo gukora ibicuruzwa bitanga ibyuma, ugomba kubanza gukora ibishishwa bishongeshejwe.

Kuberako ibi byiciro byinshi byicyiciro bisangiye intambwe rusange.

Intambwe ya 1: Gushonga

Gukora ibyuma bitagira umwanda bitangirana no gushonga ibyuma byongewe hamwe ninyongeramusaruro mu itanura ryamashanyarazi arc (EAF). Ukoresheje electrode ifite ingufu nyinshi, EAF ishyushya ibyuma mugihe cyamasaha menshi kugirango ikore ivangwa ryamazi, amazi.

Nkuko ibyuma bitagira umwanda bisubirwamo 100%, ibicuruzwa byinshi bidafite ingese birimo 60% byongeye gukoreshwa. Ibi ntibifasha kugenzura ibiciro gusa ahubwo bigabanya ingaruka kubidukikije.

Ubushyuhe nyabwo buzahinduka ukurikije urwego rwibyuma byakozwe.

Intambwe ya 2: Kuraho Ibirimo Carbone

Carbone ifasha kongera ubukana n'imbaraga z'icyuma. Nyamara, karubone nyinshi irashobora gutera ibibazo-nkimvura ya karbide mugihe cyo gusudira.

Mbere yo gutera ibyuma bidafite umuyonga, kalibrasi no kugabanya ibirimo karubone kurwego rukwiye ni ngombwa.

Hariho uburyo bubiri fondasiyo igenzura ibirimo karubone.

Iya mbere ni muri Argon Oxygen Decarburisation (AOD). Gutera gaz ya argon ivanze mubyuma bishongeshejwe bigabanya karubone hamwe no gutakaza bike mubindi bintu byingenzi.

Ubundi buryo bwakoreshejwe ni Vacuum Oxygene Decarburisation (VOD). Muri ubu buryo, ibyuma bishongeshejwe byimurirwa mu kindi cyumba aho umwuka wa ogisijeni winjijwe mu cyuma mu gihe hashyizweho ubushyuhe. Icyuho noneho gikuramo imyuka ihumeka mucyumba, bikagabanya ibirimo karubone.

Ubwo buryo bwombi butanga kugenzura neza ibirimo karubone kugirango habeho kuvanga neza nibiranga neza mubicuruzwa byanyuma bidafite ingese.

Intambwe ya 3: Kuringaniza

Nyuma yo kugabanya karubone, kuringaniza kwanyuma hamwe no guhuza ubushyuhe na chimie bibaho. Ibi byemeza ko icyuma cyujuje ibyangombwa byateganijwe kandi ko icyuma kigizwe nicyiciro cyose.

Ingero zirageragezwa kandi zirasesengurwa. Guhindura noneho bikorwa kugeza igihe ivanze ryujuje ubuziranenge busabwa.

Intambwe ya 4: Gushiraho cyangwa Gutera

Hamwe nicyuma gishongeshejwe cyaremwe, uruganda rugomba noneho gukora imiterere yambere ikoreshwa mugukonjesha no gukora ibyuma. Imiterere nubunini bizaterwa nibicuruzwa byanyuma.
