Vim li cas nws thiaj li muaj txiaj ntsig rau oscillate steel kav lossis tsim cov kua dej thaum lub sij hawm pickling?

Thaum lub sij hawm pickling ntawm steel kav, nws yog feem ntau pom hais tias: Ua ntej, thaum lub steel kav yog oscillated los yog cov pickling tov yog agitated los ntawm chav cua sov, lub pickling tus nqi yog sai dua li thaum lub steel kav yog nyob ruaj ruaj nyob rau hauv lub pickling tov. Piv txwv li, oscillating steel kav ntawm qhov ceev ntawm 30 zaug ib feeb nyob rau hauv ib lub pob tawb pickling uas txav reciprocally tuaj yeem nce tus nqi pickling li ntawm 70%. Ib yam li ntawd, nplawm cov kua qaub nrog cov cua kub tuaj yeem txhim kho tus nqi ntawm cov kav hlau los ntawm li 20%. Qhov thib ob, qhov kev txiav txim ntawm cov tshuaj pickling ntawm cov yeeb nkab steel nto txo ​​cov nqi ntawm hydrogen adhering rau nws, uas nyob rau hauv lem txo cov diffusion ntawm hydrogen rau hauv cov hlau substrate, txo cov kua qaub embrittlement thiab xyuas kom meej lub zog txhua yam ntawm cov kav hlau. Tsis tas li ntawd, cov nyhuv 冲刷 pab tshem tawm cov npuas npuas, impurities, hlau ntsev, hlau oxide nplai, thiab lwm yam adherents los ntawm steel yeeb nkab nto, uas ua rau ib tug huv si nto. Thib peb, kev ntxhov siab ntawm cov tshuaj pickling tuav ib qho kev sib xyaw ua ke, yog li ua kom cov sij hawm siv cov tshuaj pickling.
