Hauv kev lag luam steel, cov lus qhia tawm tuaj yeem pom muaj nyob rau hauv ntau yam nroj tsuag thiab cov khoom siv hauv qab thiab cov khoom siv: ua kom zoo los ntawm cov txheej txheem steelmaking thiab dov ntawm cov khoom siv raw hauv cov chaw cia khoom. Lub tshuab thiab cov cuab yeej siv no yog siv ntau yam bearings.
Cov kab ntawv qhia no ua haujlwm nyob rau hauv ib puag ncig ntawm cov txheej txheem steel, nrog rau cov plua plav steel, dej thiab cua sov. Tsis tas li ntawd, cov kabmob tuaj yeem ntsib qhov hnyav hnyav thiab kev vibration, thiab kev khiav hauj lwm ceev yog los ntawm qeeb dhau mus rau kev kub ceev, ntxiv rau kev nrawm nrawm thiab qeeb qeeb. Qhov no ua rau nws tsis tuaj yeem nrhiav qhov xav tau kev ua haujlwm ib puag ncig hauv lwm daim ntawv thov.
