I-Shandong Zhongao Steel Co. LTD itholakala eRizhao City eShayina, ngokusekelwa yizimboni, sigcina isitokwe esikhulu samakhoyili ensimbi engagqwali abandayo nashisayo, anezinga 304/304L, 316L, 430, 409L, 201 njll. Sinemigqa yethu yokukhiqiza yokusika nokusika, futhi singakhiqiza amakhoyili namashidi anoma yiluphi usayizi ngokwezicelo zamakhasimende.
Insimbi engagqwali ebangeni lama-201uhlobo lwensimbi engagqwali olunezinhlobo ezingaba ngu-200 – i-austenite (insimbi engagqwali ihlukaniswe ngezinhlobo eziyinhloko ze-austenitic, ferritic, austenitic-ferritic (Duplex)), iMartensitic, iPrecipitation Hardening). Insimbi engagqwali e-garde 201 inokuqukethwe okuphezulu kwe-manganese ne-nitrogen futhi inciphisa okuqukethwe kwe-nickel. Ngenxa yokuthi ukwakheka kwezingxenye ezahlukene kwenza insimbi engagqwali ibe nezici zebanga lama-201 uma kuqhathaniswa nezinye izinhlobo zensimbi engagqwali, kunezinzuzo ezinhle kakhulu kanye nokukhubazeka okwengeziwe.
1. Ithebula lokwakheka kwamakhemikhali lensimbi engagqwali ebangeni lama-201?
| Fe | Cr | Mn | Ni | N | Si | C |
| 72% | 16-18% | 5.5-7.5% | 3.5-5.5% | 0.25% | 1% | 0.15% |
2. Izici zensimbi engagqwali ebangeni lama-201?
Njengenye insimbi engagqwali, insimbi engagqwali ebangeni lika-201 nayo inokuqina, ukumelana nokugqwala, ukumelana nokushisa kanye nezinzuzo zokugcinwa, ukuhlanzeka kanye nobuhle. Kodwa-ke, ngenxa yezinto ezahlukene zamakhemikhali, izinga lalezi zinzuzo lihlukile kancane kunenye insimbi engagqwali. Ngokuvamile, ingxenye ye-Nikel ensimbi engagqwali ebangeni lika-201 iphansi kunensimbi engagqwali ebangeni lika-304 ngakho insimbi engagqwali ebangeni lika-201 izoba nobunzima obukhulu, ithambekele kakhulu ekugqwaleni kunensimbi engagqwali ebangeni lika-304 futhi Ubuso abukhanyi njengensimbi engagqwali ebangeni lika-304. Kodwa-ke, ukuqina kwensimbi engagqwali ebangeni lika-201 kuphakeme impela. Lokhu kungenye yamandla alethwa yinsimbi engagqwali ebangeni lika-201.
Insimbi Engagqwali ebangeni lama-201 iyinto elula ukuyisebenzisa ngenxa yesimo sayo esihle. Izindlela zomshini ezifana nokusika noma ukushisela zingenziwa kulolu hlobo lwensimbi engagqwali.
Insimbi engagqwali ebangeni lama-201 ayisebenzi kumagnethi, isetshenziswa kabanzi emikhiqizweni ethuthukisa ukumelana kwamagama. Kodwa emikhiqizweni edinga amandla okudonsa,, Insimbi engagqwali ebangeni lama-201 iyadingeka ukuze kufakwe ungqimba lwensimbi engagqwali ebangeni lama-410 noma lama-430 engqimbeni engaphandle.
3. Ingabe insimbi engagqwali esesigabeni sama-201 igqwalile?
Ngobainsimbi engagqwali ebangeni lama-201inesakhiwo se-manganese esiphezulu kanye nesilinganiso se-Nikel esiphansi, yize isici esijwayelekile sensimbi engagqwali singamelana nokugqwala, Insimbi engagqwali ebangeni lika-201 isasengozini yokugqwala kakhulu kunensimbi engagqwali ebangeni lika-304 kanye no-316. Ngakho-ke, intengo yensimbi engagqwali ebangeni lika-201 ishibhile kakhulu. Kodwa-ke, uma iqhathaniswa nezinto zensimbi ezingezona ezingagqwali (ipulasitiki, insimbi, i-aluminium …),insimbi engagqwali ebangeni lama-201kubhekwa njengokukhetha okuhle kakhulu kwemikhiqizo edinga ukuqina kanye ne-antioxidant.
4. Lingakanani izinga lokushisa lokuncibilika kwensimbi engagqwali ebangeni lama-201?
Insimbi engagqwali iyinto engamelani nokushisa. Lapho, Insimbi engagqwali ebangeni lika-201 inokushisa okuphezulu kokuncibilika cishe ku-1400 - 1450 ° C, okulingana nokushisa kokuncibilika kwensimbi engagqwali ebangeni lika-304 kodwa kuphansi kunenye insimbi engagqwali.
5. Ingabe insimbi engagqwali ebangeni lama-201 inokuhambisa ugesi?
Lo mbuzo othole ukunakwa okukhulu nemibuzo. Impendulo inguyebo kodwa ayibalulekile. Ngokungafani nensimbi yethusi eqhubayo engu-100% noma izinsimbi ezinhle eziqhubayo njengegolide, isiliva, insimbi, i-aluminium. Insimbi engagqwali ebangeni lama-201 inomthamo kagesi ophansi kakhulu. Ngakho-ke, insimbi engagqwali ayiyona eyezinto ezisetshenziselwa ukuqhuba kagesi.
