Kev paub me me

Rolling yog ib qho tseem ceeb ntawm cov dov zeb hauv lubdov zeb.Lub siab ua los ntawm ib khub lossis pab pawg yob yog siv los yob cov hlau.Nws feem ntau dais lub zog ntawm dynamic thiab zoo li qub loads, hnav thiab kub hloov thaum dov.
Muaj ob hom yob: kub yob thiab yob yob.
Cov ntaub ntawv ntawm kev ua hauj lwm rolls nyob rau hauv cov khaub thuas yob muaj xws li 9Cr, 9cr2,9crv, 8crmov, thiab lwm yam. cov yob txias yuav tsum tau deg quenching, thiab hardness yog hs45 ~ 105.
Cov khoom siv feem ntau siv rau kub dov rollers yog 55mn2,55cr, 60CrMnMo, 60simnmo, thiab lwm yam. kub dov rollers yog siv nyob rau hauv kev ua cov billet, tuab phaj, seem steel, thiab lwm yam. Nws bears lub zog dov quab yuam, hnyav hnyav thiab thermal qaug zog. , thiab cov yob kub ua haujlwm ntawm qhov kub thiab txias, thiab tso cai rau txoj kab uas hla coj mus rau hauv chav tsev ua haujlwm, yog li nws tsis xav tau qhov tawv tawv, tab sis tsuas yog lub zog siab, toughness thiab kub ua haujlwm.Qhov kub dov yob tsuas yog normalized los yog quenched tag nrho, thiab lub hardness saum npoo yuav tsum yog hb190 ~ 270.Lub hardness yob hardness yog ib qho kev tsis ncaj ncees lub cev muaj nuj nqis, thiab nws theem cuam tshuam los ntawm lub koom haum hauv lub xeev ntawm yob nws tus kheej, xws li matrix hardness ntawm cov khoom yob, hom thiab ntau ntawm carbides nyob rau hauv yob cov ntaub ntawv, cov residual kev nyuaj siab ntawm lub yob. yob, thiab lwm yam;Nyob rau tib lub sijhawm, vim tias feem ntau siv ntug dej hiav txwv thiab Leeb hardness test rau yob hardness test yog rebound hardness tests, lawv muaj kev cuam tshuam zoo heev los ntawm lub xeev ntawm cov cuab yeej ntsuas, lub hlwb ntawm cov neeg ua haujlwm thiab lwm yam.Yog li ntawd, ob qho tib si kev tsim khoom thiab kev siv lub tuam tsev ntawm cov yob yuav tsum tau muab cov neeg ua haujlwm tshwj xeeb los ua lub luag haujlwm rau kev sim hardness, ua tib zoo xaiv cov hardness tester, thiab kev sib piv nrog lwm cov hardness yuav tsum ruaj khov.Nyob rau tib lub sijhawm, xyuam xim rau qhov kev xa tawm tsis tu ncua thiab calibration ntawm hardness test instruments thiab standard test blocks.Cov tuam txhab tsim nyog tuaj yeem txhawb kev siv cov txheej txheem yob rau hardness tester calibration.
