Railway Steel Inotsanangurwa: 7 Mibvunzo Yakakosha Yese Injiniya Yezvivakwa Anofanira Kuziva

❓ Nei Dzimwe Njanji Dzichida Njanji dzeSimbi Dzakagadzikwa Panzvimbo Pedziye?

Nepo njanji dzakajairwa (seUIC60 kana AREMA 136RE) dzichishanda zvakanaka kunetiweki huru, maapplications akawanda ane hunyanzvi - akaita senjanji yenhaka, mikoto yemigodhi, machiteshi, kana mafambiro emudhorobha ane makoko akasimba -tsika njanji simbinokuda kwekuchengeteka uye kubudirira. Maprofiles akajairwa anogona kusabata mitoro yakanyanyisa, nharaunda dzinoora, kana zvimhingamipinyi zvenzvimbo. Semuyenzaniso, njanji yemugomo ine 15m-radius curves haigoni kushandisa njanji dzakatwasuka, dzakakura-dzakagadzirwa pasina njodzi yekuparara kana kukurumidza kupera. Ndipo apomaprofile enjanji anogona kugadzirika uye{{0}zvikamu zvakakombamakuva akakosha. Dzidza zvakawanda nezve njanji geometry zviyero kubvaInternational Union of Railways (UIC).

❓ Chii Chinoita Kuti Simbi yeManganese Yepamusoro Ikoshere Kumare-Haul Railways?

High manganese simbi (seMn13) inokosheswa nekuda kwe "basa-kuomesera" midziyo - kana ikanyanya kusimba, ndipo painowoma zvakanyanya. Izvi zvinoita kuti zvive zvakanakiranjanji dzinorema-inotakura 30,000+ zvitima zvematone ore, uko simbi yekabhoni yaizosakara mumwedzi yakawanda. Maererano netsvagiridzo yakabudiswa muScienceDirect, Mn-njanji dzesimbi dzinogona kugara 3–5x kureba pasi pemamiriro ekupwanya. Kana kuvhiya kwako kuchisanganisira kushushikana kwakanyanya kwemagetsi, fungahigh manganese simbi njanjisenzira-yenguva refu-yekuchengetedza mhinduro.

❓ Nhoroondo Yenjanji Inobata Sei Kuchengetedzeka Kwechitima uye Kutevera Hupenyu Hurefu?

Chimiro chenjanji - muchinjiko-chimiro chechikamu - chinokonzeresa mavhiri-kusangana kwenjanji, kugovera, uye mapatani ekupfeka. Chimiro chisina kufananidzwa chinogona kukonzera kukwira kweflange, kuwedzera kupokana, kana kukurumidza kupfeka musoro. Mitemo yakadaiISO 5003tsanangura mafaera akajairika, asi{0}mamiriro epasi rose anowanzoda misiyano. Semuyenzaniso, matramu ari mumaguta angada misoro yakapfava kuti aderedze ruzha, nepo mitsara yekutakura zvinhu ichida mawebhu akareba kuti atsigire mutoro.

Njanji dzakachinjika pa-saiti dzinogona kukonzeresa kushushikana kwemukati, zvichiita kuneta nguva isati yakwana kana kuputika. Factory-njanji dzakacheneswa, zvisinei, dzinogadzirwa pasi pekupisa kwakadzora uye kumanikidzwa, kuve nechokwadi chekuvimbika kwechimiro. Maererano neWikipedia's njanji mbiri yekupinda, macurves ari pasi pe50m radius anenge agara achida fekitori kugadzirisa.

❓ Sei Kurapwa Kwepamusoro Kwakakosha kune Njanji muMahombekombe kana Maindasitiri?

Kupfapfaidza munyu, kunyura kwemakemikari, uye hunyoro hwepamusoro zvinomhanyisa kukora - izvo zvinonetesa chimiro chenjanji uye zvinowedzera mari yekugadzirisa. Njanji dzisina kurapwa munzvimbo dzechiteshi dzinogona kuda kutsiviwa makore ese 3-5. Mishonga yemudenga senge inopisa-dip galvanizing kana epoxy coating inogona kuwedzera hupenyu hwesevhisi ne2–3x. TheNational Association of Corrosion Engineers (NACE)inokurudzira machira ekudzivirira kune chero njanji yakafumurwa kune chloride kana sulfur makomisheni. Ongorora yeducorrosion{0}}resistant njanji simbisarudzo dzezviteshi, zvidyarwa zvemakemikari, kana migwagwa yegungwa.

❓ Mitemo Yechitima Yemazuva Ano SeEN 13674-1 Inoita Sei Hunhu uye Kuenderana?

EN 13674-1 ndiyo chiyero cheEuropean chinodzora njanji, kuumbwa kwemakemikari, uye michina. Iyo inovimbisa njanji kubva kune vakasiyana vagadziri vanogona kubatanidzwa zvakachengeteka uye kuita zvinofanotaurwa pasi pemutoro. Iyo chiyero inotsanangura kushivirira kwakasimba se ± 0.1mm pazviyero zvakakosha - izvo zvatinosangana nazvo kana kudarikakugadzirwa kwenjanji. Panyaya yepasi rose, enzanisa neASTM A1(USA) kanaBS 11(UK). Kuteerera hakusi kwesarudzo - ndihwo hwaro hwekudyidzana, hwakachengeteka njanji.

❓ Nderini Paunofanirwa Kufunga Kutsiva Rails - uye Unogona Gadzirisa Kutsiva?

Rail replacement is typically triggered by head wear (>10mm vertical kurasikirwa), kutsemuka kwemukati (kunoonekwa kuburikidza ne ultrasonic bvunzo), kana ngura kutetepa. Asi usangotsiva "like-zve-like." Shandisa kutsiva semukana wekusimudzira. Semuenzaniso, kana mutsara wako wave kubata zvitima zvinorema, chinja kune 60kg/m kana 75kg/m mbiri. Kana ruzha rwuri nyaya, sarudza musoro wenjanji wakanyoroveswa. Kana corrosion iri kudya bhajeti yako, wedzera galvanizing. Withtsika njanji simbi, hauganhurwe nekabhuku kasarudzo - unogadzira mhinduro inoenderana nezvaunoda uye nezveramangwana.
