Abrasion Resistant Steel Phaj Daim Ntawv Thov
● Cov AR235 daim hlau yog tsim los rau cov ntawv siv nruab nrab uas nws muaj kev txhim kho kev hnav tsis zoo rau cov qauv carbon steel.
● AR400 yog cov khoom zoo tshaj plaws uas tiv taus cov hlau phaj uas tau kho cua sov thiab nthuav tawm los ntawm kev sib zog. Txhim kho txoj kev tsim thiab kev ua tshoob.
● AR450 yog lub phaj resistant siv nyob rau hauv ntau yam kev siv uas xav tau lub zog ntau dua li AR400.
● AR500 daim hlau yog tsim rau kev siv mining, hav zoov thiab kev tsim kho.
● AR600 yog siv rau hauv cov khoom hnav hnyav xws li kev tshem tawm tag nrho, kev khawb av, thiab kev tsim cov thoob thiab hnav lub cev.
Abrasion Resistant (AR) steel phaj feem ntau yog ua nyob rau hauv cov xwm txheej zoo li dov. Cov hom / qib ntawm cov khoom siv hlau phaj tau tsim tshwj xeeb rau kev ua haujlwm ntev hauv cov xwm txheej hnyav. AR cov khoom tsim nyog rau ntau yam kev siv hauv thaj chaw xws li mining / quarrying, conveyors, khoom tuav thiab kev tsim kho, thiab lub ntiaj teb txav. Cov neeg tsim qauv thiab cov neeg cog qoob loo xaiv AR phaj hlau thaum siv zog ua kom ntev kev pab cuam lub neej ntawm cov khoom tseem ceeb, thiab txo qhov hnyav ntawm txhua chav tsev muab tso rau hauv kev pabcuam. Cov txiaj ntsig ntawm kev ua haujlwm hnav-resistant phaj hlau hauv cov ntawv thov cuam tshuam thiab / lossis zawv zawg sib cuag nrog cov khoom siv abrasive yog qhov loj heev.
Abrasive resistant alloy steel daim hlau feem ntau muaj kev tiv thaiv zoo rau zawv zawg thiab cuam tshuam puas. Cov ntsiab lus ntawm cov pa roj carbon ntau hauv cov hlau ua kom cov tawv tawv thiab tawv tawv ntawm cov hlau, ua rau nws yog cov khoom siv zoo tshaj plaws rau cov ntawv thov uas yuav tsum tau muaj kev cuam tshuam los yog siab abrasion tsis kam. Nws yog qhov ua tau kom tau txais qhov siab hardness nrog cov pa roj carbon siab, thiab cov hlau yuav muaj kev tiv thaiv zoo rau kev nkag mus. Txawm li cas los xij, tus nqi hnav yuav nrawm dua piv rau cov khoom siv hluav taws xob kho cua sov vim tias cov pa roj carbon ntau yog nkig, yog li cov khoom tuaj yeem yooj yim dua los ntawm qhov chaw. Yog li ntawd, high carbon steels tsis siv rau kev siv siab hnav.
