Piv txwv li, siv cov hlau XAR400 uas tiv taus kev hnav zoo dua. Nws qhov nruab nrab hardness tuaj yeem ncav cuag 400HB. Nws yog ua los ntawm cov hlau alloy tshwj xeeb thiab tseem tuaj yeem ua tau zoo heev hauv cov xwm txheej hnav hnyav. Txawm hais tias nws yog rau cov thoob loader, cov hniav cement kis, lossis cov khoom siv sib tov ua vaj tse, cov hlau XAR400 tuaj yeem ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua thiab dhau los ua cov kev daws teeb meem txhim khu kev qha hauv kev lag luam hnyav. Hauv kev yuav khoom tiag tiag, nws yog qhov tseem ceeb heev rau kev xaiv tus neeg tsim khoom ntawm cov hlau tsis kam hnav.Hoobkas Hlau Phaj Uas Tiv Thaiv Kev Sib Txhuamnrog rau kev tsim khoom loj thiab kev pabcuam kev txawj ntse, vim qhov no cuam tshuam ncaj qha rau qhov sib xws ntawm cov khoom siv zoo thiab kev hloov pauv ntawm kev ua tiav tom qab.
Ua ib tug neeg koom tes tseem ceeb hauv kev lag luam xa khoom, ZZ Group tau tsim tsa hauv Yangpu District, Shanghai xyoo 1980. Txij thaum ntawd los, nws tau loj hlob mus ua ib pawg lag luam loj uas muaj ntau yam kev lag luam xws li kev lag luam hlau, kev ua thiab kev faib khoom, thiab kev nqis peev nyiaj txiag, nrog rau peev txheej sau npe ntawm 200 lab RMB. Pawg no tsis yog tsuas yog "100 lub tuam txhab ntseeg siab tshaj plaws" hauv kev lag luam hlau hauv tebchaws thiab yog 100 lub tuam txhab ntiag tug saum toj kawg nkaus hauv Shanghai, tab sis kuj, nrog nws cov txheej txheem xa khoom tiav thiab cov kev pabcuam kev tshaj lij, nws muab cov neeg siv khoom nrog kev daws teeb meem ib zaug los ntawm kev xaiv thiab kev pom zoo ntawm AR360 cov hlau tiv taus hnav.AR360 Hlau Phaj Uas Tiv Thaiv Kev Sib Txhuamrau kev ua laser txiav, pab cov neeg siv khoom txo cov nqi kho khoom siv thaum txhim kho kev ua haujlwm zoo.
Nyob rau hauv qhov sib txawv ntawm cov khoom siv hauv kev lag luam txav mus rau lub neej ntev dua thiab kev siv hluav taws xob tsawg dua, kev xaiv cov khoom siv uas tsis yooj yim hnav thiab kev cia siab rau kev txhawb nqa kev txawj ntse ntawm cov neeg muab khoom tshaj lij tau dhau los ua qhov tseem ceeb rau cov tuam txhab kom txhim kho lawv qhov kev sib tw. Txawm hais tias nws yog tus qauv AR360 lossis qhov nyuaj dua XAR400, kev xaiv cov hlau phaj uas tsis yooj yim hnav thiab kev sib xyaw nrog cov txheej txheem ua tiav yuav tsav tsheb ncaj qha rau kev ua haujlwm tshiab thiab kev txhim kho tus nqi ntawm cov khoom siv engineering.
