1. Cov Khoom Siv Hluav Taws Xob
Cov tshuaj lom neeg muaj kab ke ntawm cov nqaj hlau tsis tsuas muaj tsib qhov yooj yim hauv cov roj ntsha - carbon (lab), thiab cov pa), Hais txog naming, rail steel feem ntau pib nrog tsab ntawv "u", uas yog tus ntawv thib ob ntawm cov lus ntawm Suav pinyin ntawm lo lus "Rail" GUI. Cov naj npawb xov tooj qhia tias cov ntsiab lus carbon nruab nrab, thiab cov tsiaj ntawv txuas ntxiv qhia cov ntsiab lus alloying. Piv txwv li, U75V txhais tau tias nws cov ntsiab lus roj carbon nyob nruab nrab yog {}}. 75% thiab nws tau sib cais nrog vanadium.
2. Kev sib tw ntawm cov tsheb ciav hlau muaj zog
Lub zog theem ntawm kev ntsia yog qhov taw qhia tseem ceeb los ntsuas lawv cov khoom muaj peev xwm-coj. Raws li cov qauv sib txawv, cov ntsia yuav muab faib ua ntau qib. Piv txwv li, 780MPA-qib sib tw muaj xws li hom xws li Japanese Jis60 thiab Suav U74; 880MPA-qib kev sib tw suav nrog UIC900A thiab Suav U71MN. Raws li lub zog ua lub zog nce, cov hnav tsis kam thiab thauj khoom muaj peev xwm ntawm cov kev muag khoom ntawm cov kev muag khoom yuav nce raws li. Ntsia saum 980MPA, xws li Asmeskas Arema dived rail, Tuam Tshoj U75V Kub-Rails, thiab U77MNCRED RAID, feem ntau muaj kev muag khoom zoo thiab muaj zog. Ntsia ntawm 1080MPA thiab saum toj no yog txiav txim siab hnav cov ntsia hlau-tiv thaiv zoo rau cov kev muag khoom kub thiab 1280mpa
Peb tsom mus rau qhov tob tob txog kev sib tham ntawm kev txhawb nqa thev naus laus zis thiab tau cog lus rau kev tshawb fawb txog kev txiav nroog Txiav Hauv Kev Txiav Txim Siab. Peb lub hom phiaj yog los ua lub tshuab Innovation rau kev tsheb ciav hlau hloov chaw, thiab tib lub sijhawm sib sau ua ke ntawm cov tswv yim, txhawb nqa cov neeg muaj peev xwm thiab cov neeg ncaj ncees. Peb zoo paub tias kev txhim kho thiab kev vam meej ntawm kev vam meej subway tsis tuaj yeem sib cais los ntawm kev sib koom tes thiab lub luag haujlwm ntawm txhua tus tswv cuab.
