Cov txiaj ntsig ntawm AR Steel?
Jindalai Steel muab cov phaj hlau AR hauv cov ntim loj thiab me rau cov neeg tsim qauv thiab cov neeg ua haujlwm hauv Hoobkas uas xav kom ntev lub neej kev pabcuam ntawm cov khoom tseem ceeb thiab txo qhov hnyav ntawm txhua chav uas siv rau hauv kev pabcuam. Cov txiaj ntsig ntawm kev siv cov phaj hlau uas tiv taus kev hnav hauv cov ntawv thov uas muaj kev cuam tshuam thiab / lossis kev sib txhuam nrog cov khoom siv abrasive yog qhov loj heev.
Cov hlau phaj uas tiv taus kev sib txhuam yog cov hlau ruaj khov heev thiab tiv taus kev hnav, tiv thaiv tau zoo tiv thaiv kev khawb thiab khawb. Hom hlau no ua haujlwm tau zoo hauv kev siv hnyav, thiab kuj muaj qee qhov kev tiv taus kev cuam tshuam. Cov hlau phaj uas tiv taus kev hnav yuav pab txuas lub neej ntawm koj cov ntawv thov thiab txo koj cov nqi hauv lub sijhawm ntev.

Cov Khoom ntawm AR400 THIAB AR500 Steel Phaj
AR400 yog "thru-hardened", abrasion resistant, alloy hnav phaj. Hardness ntau yog 360/440 BHN nrog nominal hardness ntawm 400 BHN. Kev Pabcuam Kub yog 400 ° F. Cov phaj no yog tsim los siv rau hauv cov ntawv thov uas xav tau kev sib npaug zoo ntawm formability, weldability, toughness thiab abrasion tsis kam. Abrasion resistant steels feem ntau muag rau qhov nyuaj thiab tsis yog ib qho tshuaj lom neeg ruaj khov. Me ntsis kev hloov pauv hauv chemistry muaj nyob ntawm lub zeb tsim khoom. Cov ntawv thov yuav suav nrog kev siv hauv kev khawb av, quarries, kev tuav cov khoom loj, cov zeb hlau, thiab kev lag luam pulp & ntawv. Cov phaj hnav yog tsim los rau cov ntawv thov liner; lawv tsis yog rau kev siv ua cov qauv txhawb nqa tus kheej lossis cov khoom siv nqa.
AR500 yog ib daim phaj hlau uas "tru-hardened", tiv taus kev sib txhuam, thiab ua los ntawm cov hlau alloy. Qhov nyuaj yog 470/540 BHN nrog qhov nyuaj nominal ntawm 500 BHN. Cov phaj no yog tsim los siv rau hauv cov ntawv thov uas xav tau kev sib npaug zoo ntawm kev cuam tshuam, kev tawv thiab kev tiv taus kev sib txhuam. Cov hlau uas tiv taus kev sib txhuam feem ntau muag rau qhov nyuaj thiab tsis yog cov tshuaj lom neeg ruaj khov. Muaj kev hloov pauv me ntsis hauv cov tshuaj lom neeg nyob ntawm lub Hoobkas tsim khoom. Cov ntawv thov yuav suav nrog kev siv hauv kev khawb av, chaw txua zeb, kev tuav cov khoom loj, cov chaw zeb hlau, thiab kev lag luam pulp & ntawv. Cov khoom phaj hlau yog tsim los rau cov ntawv thov liner; lawv tsis yog rau kev siv ua cov qauv txhawb nqa tus kheej lossis cov khoom siv nqa.
AR400 VS AR450 VS AR500+ Cov Phaj Hlau
Cov chaw ua hlau sib txawv yuav muaj cov "zaub mov txawv" rau AR hlau, tab sis cov khoom tsim tawm raug muab kev sim qhov nyuaj - hu ua Brinell Test - los txiav txim siab pawg uas nws poob. Kev sim Brinell ua rau cov khoom siv hlau AR feem ntau ua tau raws li ASTM E10 cov lus qhia rau kev sim qhov nyuaj ntawm cov khoom siv.
Qhov sib txawv ntawm AR400, AR450 thiab AR500 yog tus lej Brinell Hardness (BHN), uas qhia txog qib hardness ntawm cov khoom.
AR400: 360-440 BHN Feem ntau
AR450: 430-480 BHN Feem ntau
AR500: 460-544 BHN Feem ntau
AR600: 570-625 BHN Feem ntau (tsis tshua muaj, tab sis muaj)
