Abantu bakunze gutekereza ko magnesi ikurura ibyuma bitagira umwanda kugirango igenzure ubuziranenge nukuri. Niba idakurura ibicuruzwa bitari magnetique, bifatwa nkibyiza kandi byukuri; niba ikurura magnesi, ifatwa nkimpimbano. Mubyukuri, ubu ni uburyo bumwe cyane, budashoboka kandi butari bwo bwo kumenyekana.
Hariho ubwoko bwinshi bwibyuma bitagira umwanda, bishobora kugabanywamo ibyiciro byinshi ukurikije imiterere yabyo mubushyuhe bwicyumba:
1. Ubwoko bwa Austenitike: nka 304, 321, 316, 310, nibindi.;
2. Ubwoko bwa Martensite cyangwa ferrite: nka 430, 420, 410, nibindi.;
Austenite ntabwo ari magnetique cyangwa magnetique idakomeye, mugihe martensite cyangwa ferrite ni magnetique.
Ibyinshi mubyuma bidafite ingese mubisanzwe bikoreshwa mumabati yo gushushanya ni ibikoresho bya austenitis 304. Muri rusange, ntabwo ari magnetique cyangwa magnetique. Ariko, kubera ihindagurika ryimiterere yimiti bitewe no gushonga cyangwa uburyo butandukanye bwo gutunganya, magnetism nayo irashobora kubaho, ariko ibi ntibishobora gufatwa nkibihimbano cyangwa bitujuje ibisabwa, niyihe mpamvu?
Nkuko byavuzwe haruguru, austenite ntabwo ari magnetique cyangwa magnetique idakomeye, mugihe martensite cyangwa ferrite ni magnetique. Bitewe no gutandukanya ibice cyangwa kuvura ubushyuhe budakwiye mugihe cyo gushonga, hazaterwa umubare muto wa martensite cyangwa ferrite muri austenitis 304 ibyuma bitagira umwanda. umubiri. Muri ubu buryo, ibyuma 304 bidafite ingese bizaba bifite magnetisme idakomeye.
Mubyongeyeho, nyuma yo gukora ubukonje bwa 304 ibyuma bidafite ingese, imiterere yubuyobozi nayo izahinduka martensite. Nubunini urwego rwo guhindura imikorere ikonje, niko guhinduka kwa martensitike, hamwe na magnetisme yicyuma. Nkumubare wibyuma byumurongo wibyuma,ΦImiyoboro 76 ikorwa. Nta kwinjiza magnetique kugaragara, kandiΦImiyoboro 9.5 ikorwa. Kuberako ihindagurika ryunamye ari rinini, induction ya magnetique izagaragara cyane. Guhindura imiyoboro ya kare iringaniye ni nini kuruta iy'uruziga ruzengurutse, cyane cyane igice cy'imfuruka, ihindagurika rirakomeye kandi magnetism iragaragara.
Kugirango ukureho burundu magnetisme yicyuma 304 yatewe nimpamvu zavuzwe haruguru, imiterere ihamye ya austenite irashobora kugarurwa hifashishijwe uburyo bwo kuvura ubushyuhe bwo hejuru, bityo bikuraho magnetism.
By'umwihariko, twakagombye kwerekana ko magnetism ya 304 ibyuma bitagira umwanda kubera impamvu zavuzwe haruguru ntabwo biri kurwego rumwe na magnetisme yibindi bikoresho bidafite ingese, nka 430 nicyuma cya karubone. Muyandi magambo, magnetism yicyuma 304 burigihe yerekana imbaraga za magnetisme.
Ibi bitubwira ko niba ibyuma bidafite ingese bifite magnetisme idakomeye cyangwa nta magnetisme namba, bigomba kumenyekana nkibikoresho 304 cyangwa 316; niba ifite magnetisme nkicyuma cya karubone kandi ikerekana magnetisme ikomeye, igomba kumenyekana nkibikoresho 304.
Itsinda rya Jindalaitekereza ko mugihe uguze ibicuruzwa bitagira umwanda, ugomba guhitamo ibicuruzwa mubakora bazwi. Ntukifuze ibiciro bihendutse kandi witondere gushukwa. Itsinda rya Jindalai Steel Group ninganda nini nini yinganda zidafite ibyuma ninganda zubucuruzi zihuza ibyuma bidafite ibyuma byinshi, gutunganya, kubika no gukwirakwiza. Ishingiye ku cyizere no gufashwa na bagenzi be mu gihugu ndetse no hanze yarwo, isosiyete yakuze iba imwe mu mishinga minini ihuza umusaruro n’ubucuruzi mu nganda z’ibyuma bitagira umwanda nyuma y’imyaka irenga icumi yiterambere n’iterambere.
