Icyuma ni iki?
Icyuma ni icyuma cy’icyuma kandi ikintu cy’ingenzi (cy’ingenzi) cyo gushushanya ni Karuboni. Ariko, hari ibitandukanye kuri ubu busobanuro nk’ibyuma bitagira interstitial (IF) n’ibyuma bitagira ferritic 409, aho karuboni ifatwa nk’umwanda.
Alloy ni iki?
Iyo ibintu bitandukanye bivanze mu rugero ruto mu gice cy’ibanze, umusaruro uvamo witwa ingano y’ikintu cy’ibanze. Bityo icyuma ni ingano y’icyuma kuko icyuma ari cyo kintu cy’ibanze (igice cy’ingenzi) mu cyuma naho ikintu cy’ingenzi giteranya ni Karuboni. Ibindi bintu nka Manganese, Silicon, Nikeli, Chromium, Molybdenum, Vanadium, Titanium, Niobium, Aluminium, nibindi nabyo byongerwa mu rugero rutandukanye kugira ngo bikore ubwoko butandukanye bw’icyuma.
Jindalai (Shandong) Steel Group Co., Ltd. ni umuhanga mu gutanga ibyuma n'imiyoboro/imiyoboro/amasahani by'ibyuma bitagira umugese. Ohereza ikibazo cyawe maze tuzishimira kugisha inama by'umwuga.
Ni ubuhe bwoko butandukanye bw'ibyuma?
Hashingiwe ku miterere y'ibinyabutabire, Icyuma gishobora gushyirwa mu byiciro bine (04) by'ibanze:
● Icyuma cya karuboni
● Icyuma kitagira umwanda
● Icyuma cy'Aluminiyumu
● Igikoresho cy'icyuma
1. Icyuma cya karuboni:
Ibyuma bya karuboni ni byo byuma bikoreshwa cyane mu nganda kandi bingana na 90% by'umusaruro wose w'ibyuma. Hashingiwe ku gipimo cya karuboni, ibyuma bya karuboni bishyirwa mu matsinda atatu.
● Icyuma gito cya karuboni/Icyuma gito
● Icyuma giciriritse cya karuboni
● Icyuma cya karuboni nyinshi
Ingano ya karuboni igaragazwa mu mbonerahamwe iri hepfo:
| Oya. | Ubwoko bw'icyuma cya karuboni | Ijanisha rya Karuboni |
| 1 | Icyuma gito cya karuboni/Icyuma gito | Kugeza kuri 0.25% |
| 2 | Icyuma giciriritse cya karuboni | 0.25% kugeza 0.60% |
| 3 | Icyuma cya karuboni nyinshi | 0.60% kugeza kuri 1.5% |
2. Icyuma kitagira umwanda:
Icyuma kidashonga ni icyuma gikozwe mu cyuma gifite 10.5% bya Chromium (Nine). Icyuma kidashonga kigaragaza ubushobozi bwo kurwanya ingese, bitewe no kuba hari urwego ruto cyane rwa Cr2O3 ku buso bwacyo. Uru rwego ruzwi kandi nka passive layer. Kongera ingano ya Chromium byongera ubushobozi bwo kurwanya ingese ku bikoresho. Uretse Chromium, Nickel na Molybdenum nabyo byongerwamo kugira ngo bitange imiterere yifuza (cyangwa inoze). Icyuma kidashonga gifite kandi ingano zitandukanye za Karuboni, Silikoni, na Manganese.
Ibyuma bitazangiza ibyuma bishyirwa mu byiciro bikurikira:
1. Ibyuma bitagira umugese bya Ferritic
2. Ibyuma bitagira umugese bya Martensitic
3. Ibyuma bitagira umugese bya Austenitic
4. Ibyuma bibiri bitagira umugese
5. Ibyuma bitagira umwanda bifasha mu gukuba (PH)
● Ibyuma bita ferritic stainless: Ibyuma bita ferritic bigizwe n'ibyuma bya fer-chromium bifite imiterere ya cubic crystal (BCC) ishingiye ku mubiri. Muri rusange ibi bifite magnetic kandi ntibishobora gukomera hakoreshejwe ubushyuhe ariko bishobora gukomezwa no gukora ibintu bikonje.
● Icyuma cya Austenitic Stainless Steel: Icyuma cya Austenitic kirwanya ingese cyane. Ntigikoresha ingufu za rukuruzi kandi ntigishobora kuvurwa n'ubushyuhe. Muri rusange, icyuma cya austenitic gishobora gusukurwa cyane.
● Ibyuma bita Martensitic Stainless Steel: Ibyuma bita Martensitic stainless Steel birakomeye cyane kandi birakomeye ariko ntibirwanya ingese nk'izindi nzego ebyiri. Ibi byuma birakoreshwa cyane mu gukora, bifite imbaraga za rukuruzi, kandi biravurwa n'ubushyuhe.
● Ibyuma Bidasanza: Ibyuma Bidasanza bibiri bigizwe n'imiterere mito y'ibice bibiri igizwe n'ibice by'icyuma gidasanza cya ferritic na austenitic (ni ukuvuga Ferrite + Austenite). Ibyuma Bidasanza bibiri birusha imbaraga ibyuma bidasanza bya austenitic cyangwa ferritic.
● Ibyuma bitagira umwanda (PH) byuma bitagira umwanda: Ibyuma bitagira umwanda (PH) byuma bitagira umwanda bifite imbaraga nyinshi cyane bitewe n’uko imvura ikomera.
3. Icyuma cy'Aluminiyumu
Mu byuma bya aluminiyumu, hakoreshwa ibipimo bitandukanye by'ibintu bivangavanze, kugira ngo hagerwe ku miterere yifuza (inoze) nko gusudira, guhindagurika, ubushobozi bwo gukora, gukomera, gukomera no kurwanya ingese, nibindi. Bimwe mu bintu bivangavanze bikoreshwa cyane n'ingaruka zabyo ni ibi bikurikira;
● Manganese – Yongera imbaraga n'ubukomere, igabanya ubushobozi bwo gupfuka no gusudira.
● Silicone – Ikoreshwa nk'ibintu bikuraho uburozi bikoreshwa mu gukora icyuma.
● Fosifore – Yongera imbaraga n'ubukomere kandi ikagabanya ubushobozi bwo gukora no gukomera kw'icyuma.
● Sulfure – Igabanya ubushobozi bwo gupfuka, gukomera kw'ingufu, no gusonera. Iboneka mu buryo bw'ibice bya sulfide.
● Umuringa – ubudahangarwa bw’ingufu bwarushijeho kwiyongera.
● Nickel – Yongera ubushobozi bwo gukomera no gukomera kw'ibyuma.
● Molybdenum – Yongera ubushobozi bwo gukomera no kongera ubushobozi bwo kudakora neza kw'ibyuma bidafite aloyi nyinshi.
4. Igikoresho cy'icyuma
Ibyuma by'ibikoresho bifite karuboni nyinshi (0.5% kugeza 1.5%). Ibyuma byinshi bya karuboni bitanga ubukana n'imbaraga byinshi. Ibi byuma bikoreshwa cyane mu gukora ibikoresho n'uduti. Ibyuma by'ibikoresho birimo ingano zitandukanye za tungsten, cobalt, molybdenum, na vanadium kugira ngo byongere ubushyuhe n'ubudasaza, ndetse birambe. Ibi bituma ibyuma by'ibikoresho biba byiza cyane mu gukoresha nk'ibikoresho byo gukata no gucukura.
Jindalai Steel Group igumana ibintu byinshi by’ibyuma byiza cyane mu nganda. Jindalai irashobora kugufasha guhitamo ibikoresho by’icyuma bikwifuje kugira ngo ubone ibyo ukeneye vuba bishoboka igihe cyo kugura. Niba kugura ibikoresho by’icyuma biri hafi yawe, saba ikiguzi. Tuzaguha kimwe kizaguha ibicuruzwa ukeneye byihuse.
