Nto roughness yog ib qho khoom tseem ceeb ntawm cov pob steel, vim nws tuaj yeem cuam tshuam lawv txoj haujlwm thiab ua haujlwm ntev. Yog li ntawd, nws yog ib qho tseem ceeb los ntsuas qhov roughness ntawm cov pob steel thiab nkag siab txog nws txoj kev ua tau zoo.
Txhawm rau kuaj qhov roughness ntawm cov pob steel, ib txwm siv lub ntsej muag roughness tester lossis profileometer. Tus ntsuas ntsuas kab rov tav thiab ntsug sib txawv ntawm lub pob saum npoo ntawm qhov zoo tagnrho. Cov txiaj ntsig tau nthuav tawm raws li Ra, Rq, Rz, lossis lwm yam kev ntxhib los mos ntawm qhov chaw.
Qhov cuam tshuam ntawm qhov roughness ntawm cov pob steel tuaj yeem yog qhov tseem ceeb. Piv txwv li, nyob rau hauv high speeds, deg roughness yuav cuam tshuam rau lub pob dov tsis kam thiab ua rau kom lub pob thiab lub pob thiab nws ib puag ncig. Tsis tas li ntawd, deg roughness kuj tuaj yeem cuam tshuam lub pob lub peev xwm los tiv thaiv kev cuam tshuam, uas yog qhov tseem ceeb hauv kev lag luam.
Ntxiv mus, deg roughness kuj tuaj yeem cuam tshuam lub pob qhov corrosion kuj. Ib qho chaw ntxhib tuaj yeem ua rau thaj tsam ntawm qhov chaw corrosion tuaj yeem tshwm sim, txo lub pob lub neej thiab kev ua haujlwm tag nrho. Yog li ntawd, nws yog ib qho tseem ceeb kom tswj tau qhov zoo ntawm qhov chaw roughness qib rau steel pob hauv ntau daim ntawv thov.
Txhawm rau txiav txim siab, ntsuas qhov roughness ntawm cov pob steel thiab nkag siab txog nws qhov cuam tshuam rau lub pob qhov kev ua tau zoo yog qhov tseem ceeb. Los ntawm kev saib xyuas thiab tswj xyuas qhov roughness ntawm cov pob steel, cov tuam ntxhab tuaj yeem ua kom cov khoom zoo sib xws thiab kev ua haujlwm zoo dua.
