Kutanga, hunhu hwechiromium yakakanda simbi
Yakakwira Chromium yakakandira iron rudzi rwekukandirwa simbi ine yakakwira chromium yezvinyorwa. Nekuda kwekuwedzera kweChromium, Highmium yakakanda simbi ine simba kupfeka, kuramba uye zvivakwa zvakakura zvekugadzira michina, uye michina yekugadzira, yemuchina uye mamwe minda.
2. Kupisa kurapa nzira yeakakwira chromium yakakanda iron
Nezve nzira dzekurapa dzekurapa dzechromium yakakanda simbi, nzira dzakasiyana senge dzakajairwa, kudzima uye kutsamwa kunowanzo shandiswa kuomesa kuomarara uye simba rezvinyorwa.
1. Normende
Iyo yakanaka yekupisa kurapa nzira ndeye kudzokorora kupisa yakakwira chromium yakakanda simbi panzvimbo yakakwira tembiricha yeanenge 500℃kuti uwane mhedzisiro yezvinyorwa. Yakanga yakajairika inogona kuvandudza simba uye kuomesa kwekrommium yakakanda simbi, asi zvakare kutungamira kuwanda kwechipenga chezvinyorwa.
Nhanho 2 Quench
Kupedzisa ndiko kurapa kwekrromiom yakakanda simbi mune tangi ine inotonhorera kuzadzisa kuomarara uye simba rezvinyorwa. Iyo tembiricha yekupisa kazhinji iri pakati pe800 uye 980℃c, uye kutonhora kwakanyanya nekukurumidza kunofanirwa kudzivirirwa kudzivisa kupaza mune izvo zvinyorwa.
3. Hasha
Kutsamwa kuri mushure mekupedza kurapwa, uye ipapo iyo yakakwira chromium yakakandwa simbi inoiswa kune imwe tembiricha yekushisa kurapwa, kuitira kuderedza kuomarara kwezvinhu, uku uchivandudza hutsinye uye kuva mufaro. Iyo tembiricha yekudziya yekushambadzira ndeye 280 ~ 520 degree, uye nguva iri anenge 1 ~ maawa matatu.
Chetatu, pesvedzero yezvinhu zvakasiyana zvekupedza kurapa nzira pakakwirira chromium yakakanda iron
Nzira dzakasiyana dzekupisa dzekurapa dzine mhedzisiro dzakasiyana. Nekuda kweiyo yakakwira chromium yezvinyorwa, yakakwira chromium yakakandira iron inowanzoitika kuChromization mukurapwa, izvo zvinokanganisa zvivakwa zvezvinyorwa. Naizvozvo, usati wabata kupisa, tembiricha yakakodzera yehondo uye nguva inofanira kusarudzwa kuti ideredze kukanganiswa kwe chromatization pazvinhu zvekushandisa.
Kugadzirisa kurapwa kunogona kuvandudza kuomarara uye simba rechinyorwa, asi zvichikanganisa kuomarara kwaro uye ductility, uye zviri nyore kupaza uye zvimwe zvinetso. Kupedzisa kurapwa kunogona kuvandudza kuomesesa uye simba rechinyorwa, uye chengetedza zvakanaka kwazvo kupfeka kupokana uye kupokana. Mushure mekutsamwa, kuomarara kwezvinhu zvakaderedzwa, kuomarara uye kugadzikana kwakagadziridzwa, asi panguva imwe chete, kupfeka kupokana uye kupokana kwezvinhu zvakaderedzwa.
Iv. Pfupiso
Hunhu hwechromium yakakanda simbi adzisei kuti titeerere kuchenjera kune chiitiko che chromic phenomenon mune yekupisa kurapa maitiro, uye sarudza yakakodzera yekupisa kwekurapa nzira. Kurapa kwakasiyana, kwakadai sekujairika, kudzima nekutsamwa, sarudza kuomarara, kuoma, tuctility, kupfeka kuramba uye kukanganisa kwezvinhu. Mukuita kwekushandiswa, zvinodikanwa kusarudza iyo yakakodzera yekupisa kurapa nzira zvichienderana neye chaiyo yekushandisa mashandiro ekuita basa rakanakisa reChromium yakakandwa zvigadzirwa zvesimbi.
