Nhau - Unoziva Nezve AREMA Standard Steel Rail?

Nzira yekugadzira yeAREMA yakajairika simbi njanjikazhinji inosanganisira matanho anotevera:
Kugadzirira kwezvinhu: Gadzirira zvigadzirwa zvesimbi, kazhinji zvemhando yepamusoro kabhoni structural simbi kana yakaderera alloy simbi.
Kunyunguduka nekukanda: Izvo zvinhu zvakanyungudutswa zvinonyungudutswa, uye ipapo simbi yakanyungudutswa inokandwa mumabhiliti ekutanga esimbi kuburikidza nekuramba vachikanda kana kudurura.
Kukwenenzvera nekukungurutsira: Kukwenenzvera simbi yekutanga, kusanganisira kubvisa tsvina uye kugadzirisa maumbirwo, uyezve kutenderedza simbi yesimbi kuburikidza nemidziyo inomonereka kuita mabheti etrack anoenderana nemitemo yenyika.
Pretreatment: Pretreatment of track billets, kusanganisira forging, heat treatment and surface treatment, etc., kuvandudza simba nekusimba kwenjanji.
Kukungurutsa nekugadzira: Iyo pre-yakagadziriswa track billet inokungurutswa uye inoumbwa kuburikidza nemuchina wekutenderedza kuti iite njanji inoenderana nezvinodiwa nenyika.
Kuongorora uye kutonga kwemhando: Kuongorora kwakasimba uye kutonga kwemhando kunoitwa panjanji dzakagadzirwa kuona kuti dzinosangana nenyika uye zvinodiwa nevatengi.
Kurongedza uye kusiya fekitori: Rail dzakakwana dzinoiswa mukati uye dzakamakwa, dzobva dzaendeswa kumutengi kana kuchengetwa mudura dzakamirira kutumirwa.

ASTM yakajairika simbi njanji vane hunhu hunotevera:

Simba repamusoro: American standardnjanjidzakagadzirwa nesimbi yemhando yepamusoro, ine simba repamusoro uye yakasimba uye inogona kumirisana nekuremerwa uye kushanda kwezvitima.

Kumisikidzwa kwezvakatemerwa: Izvo zvakatemwa uye zvimiro zveAmerican standard rails zvakanyatsogadzirwa zvinoenderana nezviyero, kuve nechokwadi chekufanana uye kuchinjana kwechitima system.

Kuramba kwakasimba kupfeka: Iyo yepamusoro yeAmerican njanji yakabatwa zvakanyanya uye ine yakasimba kupfeka kuramba, iyo inogona kuderedza kupfeka kwenjanji uye kuwedzera hupenyu hwebasa.

Yakanaka corrosion resistance: Iyo yepamusoro yeAmerican standard rails yakarapwa anti-corrosion treatment, inogona kuramba oxidation uye corrosion uye kuchengetedza kushandiswa kwakanaka.

Hurukuro hwekushandisa: Njanji dzeAmerican dzakakodzera njanji dzakasiyana-siyana, dzinosanganisira njanji dzinomhanya-mhanya, njanji dzakajairwa uye njanji dzekutakura zvinhu, nezvimwewo, uye dzine simba rakasiyana-siyana uye kushanda.
