Cov txiaj ntsig ntawm ar hlau?
Jindalai Steel cov khoom siv ntawm cov phaj loj rau cov neeg tsim qauv thiab cov nroj tsuag tsav tsheb mus txuas ntxiv rau lub neej tseem ceeb thiab txo qhov hnyav ntawm txhua txhua qhov kev pabcuam. Cov txiaj ntsig ntawm kev ua haujlwm hnav cov ris-tiv taus steel phaj hauv cov ntawv thov uas muaj feem cuam tshuam nrog kev cuam tshuam thiab / lossis zawv zawg kev sib cuag nrog cov khoom muaj abrasity yog qhov tseem ceeb.
Puas tsim av hlau phaj yog qhov ruaj khov thiab hnav-resistant, tiv thaiv zoo tawm tsam cov scuffs thiab khawb. Hom qauv no ua haujlwm zoo hauv cov ntawv thov hnyav, thiab tseem muaj qee qhov cuam tshuam tiv thaiv. Hnav cov kav hlau tiv thaiv STEEL STEEL STEEL STEEN yuav pab txuas ntxiv lub neej ntawm koj cov ntawv thov thiab txo koj cov nqi hauv kev ntev.

Cov khoom ntawm Ar400 thiab Ar500 Steel Phiaj
AR400 yog "thru-hardened", kev puas tsuaj tiv taus, alloy hnav phaj. Hardness ntau yog 360/440 bhn nrog ib qho nominal hardness ntawm 400 bhn. Kev pabcuam kub yog 400 ° F. Cov khoom lag luam phaj no yog npaj rau siv rau hauv cov ntawv thov uas qhov sib npaug zoo ntawm cov muaj peev xwm, weldability tsis kam yog xav tau. Puas Tsuaj cov hlau tsis tshua muaj feem ntau muag rau qhov nyuaj thiab tsis yog cov kev siv tshuaj kho. Me ntsis txawv txav hauv chemistry yog tam sim no nyob raws li cov khoom lag luam. Cov ntawv thov yuav suav nrog kev siv hauv kev sib khuav, cov neeg sib cav, ntau cov khoom siv, cov mills, thiab pulp & cov ntawv lag luam thiab kev lag luam & pulp & cov ntawv lag luam. Hnav cov khoom lag luam phaj yog tsim los rau cov ntawv thov liner; Lawv tsis yog npaj rau kev siv ua kev txhawb nqa tus kheej lossis nqa khoom siv.
AR500 yog "haru-harru", kev puas tsuaj tiv taus, alloy hnav phaj. Cov Hardness ntau yog 470/540 BTH nrog ib qho nominal hardness ntawm 500 bhn. Cov khoom lag luam phaj no yog npaj rau siv rau hauv cov ntawv thov uas qhov sib npaug zoo ntawm kev cuam tshuam, kev ua tsis zoo thiab kev puas tsuaj tsis kam. Puas Tsuaj cov hlau tsis tshua muaj feem ntau muag rau qhov nyuaj thiab tsis yog cov kev siv tshuaj kho. Me sib txawv hauv Chemistry yog tam sim no nyob ntawm cov khoom tsim khoom. Cov ntawv thov yuav suav nrog kev siv hauv kev sib khuav, cov neeg sib cav, ntau cov khoom siv, cov mills, thiab pulp & cov ntawv lag luam thiab kev lag luam & pulp & cov ntawv lag luam. Hnav cov khoom lag luam phaj yog tsim los rau cov ntawv thov liner; Lawv tsis yog npaj rau kev siv ua kev txhawb nqa tus kheej lossis nqa khoom siv.
A400 VS ar450 vs ar500 + steel phiaj
Cov mills sib txawv yuav muaj cov zaub mov sib txawv "rau kev sim ua kom muaj zog - hu ua kev sim Brinell - los txiav txim siab rau qeb uas nws ntog. Brinell cov ntawv xeem ua rau ntawm cov ntaub ntawv hlau feem ntau ua tiav Astm E10 specifications rau kev sim cov khoom hardness.
Qhov kev sib txawv ntawm AR400, AR450 thiab AR450 thiab AR500 yog tus lej Brinell tus lej (BNT), uas qhia txog cov khoom siv theem ntawm Hardness.
AR400: 360-440 BEK feem ntau
AR450: 430-480 Bhn feem ntau
AR500: 460-544 Bhn Feem Ntau
AR600: 570-625 Bhn - Ntau zaus (tsawg dua, tab sis muaj)
