Tus ntsia hlau cais tau muab tso rau qhov hnyav rau hauv 75kg / m, 60kg / m, 50kg / m, 43kg / m thiab lwm hom. Ntawm lawv, 60kg / m thiab 50kg / m rails tau muab tso rau ntawm cov kab tseem ceeb. Cov kev sib tw no feem ntau yog ua los ntawm cov hlau manganese, thiab cov qauv siv yog lub teb chaws tus qauv gb {6}}.
1. Hom
Cov ntsia hlau Suav tuaj yeem muab faib ua peb hom raws li qhov hnyav rau ib lub 'meter': lub tsheb ciav hlau, kev tsheb ciav hlau hnyav thiab CRAIL. Lub teeb ntawm feem ntau muaj cov kev sib yeem sib txawv xws li 9, 12, 15, thiab 30kg / m, uas yog siv rau hauv nroog ciav hlau Hla thiab Mining Railways. Hnyav rails tsuas yog muaj kev tsheb ciav hlau xws li 38, 43, thiab 50kg / m. Ntawm lawv, 60kg / m thiab 50kg / m rails yog pw ntawm cov loj pob tw, thiab 43kg / m sib tw yog feem ntau siv rau cov kab chaw nres tsheb thiab cov kab mob siab. Crane cov nqaj yog tsuas yog siv rau cov ciav hlau rau cranes thiab lwm cov cuab yeej hnyav, thiab lawv qhov hnyav tuaj yeem mus txog 118kg / m.
2. Cov khoom siv ntawm cov ntsia hlau
Feem ntau cov kev muag khoom Suav yog tsim los ntawm manganese steel, xws li U71MN, 50mn, thiab hnav tsis kam, thiab tuaj yeem tiv thaiv lub siab loj thiab muaj peev xwm tiv thaiv lub log loj thiab muaj peev xwm Tsis tas li ntawd, nyob ntawm lub hom phiaj thiab siv ib puag ncig, lwm cov aluminium ntsiab yuav raug ntxiv rau cov ntsia hlau los txhim kho lawv cov kev ua tau zoo, xws li tooj liab, silicon, thiab lwm yam.
3. Cov qauv siv ntawm cov ntsia
Tus ntsia hlau Suav siv cov qauv hauv tebchaws GB 2585-2007. Tus qauv no qhia cov lus thiab cov ntsiab lus, cov ntsiab lus tseem ceeb, cov kev cai ntsuas, kev tshuaj xyuas, thiab lwm yam ntawm kub-dov rail rau kev tsheb ciav hlau. Kev siv ntawm cov qauv no kom ua tau zoo thiab nyab xeeb ntawm cov ntsia hluav taws thiab muab kev lees paub txoj kev tsheb ciav hlau du thiab nyab xeeb.
