Nyob rau hauv kub-kuav los tiag steel ntau lawm, qhov zoo ntawm cov yob siv nyob rau hauv cov txheej txheem tuaj yeem muaj kev cuam tshuam loj rau cov khoom kawg. Ib qho kev xaiv nrov rau cov yob no yoghigh chromium hlau rollers, tseem hu ua cam khwb cia hlau rollers. Cov yob no paub txog lawv cov kav ntev, ua haujlwm kub thiab tag nrho kev ua haujlwm siab thaum lub sijhawm kub dov.

High chromium hlau yobyog tsim los ntawm cam khwb cia hlau nrog cov ntsiab lus siab chromium. Cov hlau muaj qhov hnav zoo heev thiab ua haujlwm kub, ua rau nws yog cov khoom siv zoo tshaj plaws rau kub dov mills. Cov ntsiab lus chromium siab kuj muab cov yob siab hardness, uas ntxiv rau kev siv lub neej ntawm cov yob thiab pab kom lawv tuaj yeem tiv taus qhov hnyav thiab kub koom nrog hauv cov txheej txheem dov.

Ib qho ntawm qhov zoo ntawm kev sivhigh-chromium hlau yob nyob rau hauv kub dov mills yog lawv lub peev xwm los tswj lawv cov duab thiab nto zoo nyob rau lub sij hawm. Qhov no yog qhov tseem ceeb los xyuas kom meej qhov zoo sib xws thiab ua tau zoo ntawm cov khoom steel. Lub tshav kub tsis kam ntawm cov chais no kuj tso cai rau kev ua haujlwm tau zoo, tsis tu ncua tsis tas yuav tsum tau hloov pauv lossis tu.

Ntxiv nrog rau kev ua haujlwm ntev, high-chromium hlau rolls muaj qhov sib luag, zoo ib yam, uas yog qhov tseem ceeb rau kev tsim cov khoom zoo steel. Qhov kev ua tiav saum npoo no pab tiv thaiv txhua qhov blemishes lossis imperfections hauv cov hlau dov, ua rau cov khoom zoo kawg.

Tsis tas li ntawd, nyob rau hauv lub sij hawm ntev, siab chromium hlau rolls muab qhov kom zoo dua ntawm kev ua tus nqi zoo vim lawv lub neej kev pab cuam ntev dua thiab kev saib xyuas tsawg. Qhov no ua rau lawv muaj peev xwm ntse rau cov neeg tsim khoom steel tab tom nrhiav los txhim kho lawv cov txheej txheem kub dov thiab cov khoom zoo.

Nyob rau hauv cov ntsiab lus, siab chromium hlau yob yog thawj qhov kev xaiv rau kub dov steel yob vim lawv zoo heev durability, tshav kub tsis kam thiab tag nrho cov kev ua tau zoo. Los ntawm kev siv cov yob no hauv cov kub dov mills, steelmakers tuaj yeem ua kom ntseeg tau thiab ua haujlwm zoo thaum txo cov nqi kho thiab hloov cov nqi. High chromium hlau coils muaj ntau yam zoo thiab yog ib qho khoom muaj nqis rau kev lag luam steel.
