Cov nyhuv ntawm cov txheej txheem sib txawv ntawm cov nyhuv derusting ntawm cov phab ntsa tuab stainless hlau seamless raj

Raws li kev txheeb xyuas tus qauv lej, qhov kev sim cov ntaub ntawv ntawm kev vibration derusting txheej txheem tsis rau tuab-walled stainless hlau seamless raj tau tsim.Cov kev ntsuam xyuas kev vibration derusting tau ua nyob rau hauv ntau cov lus qhia kev co rau cov txheej txheem tsis muaj kev cuam tshuam rau kev co derusting nyhuv ntawm tuab-walled stainless hlau seamless raj, thiab macroscopic thiab metallographic sib piv tshuaj xyuas ntawm cov nyhuv derusting tau ua tiav.Cov nyhuv ntawm cov txheej txheem sib txawv ntawm cov nyhuv derusting ntawm tuab-walled stainless hlau seamless raj tau soj ntsuam thiab kuaj.(1) abrasive hardness xeb lub koom haum yog xoob, tab sis cov oxide txheej ntawm cov hlau nto thiab cov khoom siv hauv paus ua ke muaj zog yog siab, qhov siab dua particle hardness, qhov zoo dua cov nyhuv ntawm kev tshem tawm xeb thiab oxide txheej rau cov khoom ntawm tib yam khoom. , qhov loj yog qhov loj, thiab qhov chaw sib cuag ntawm cov khoom thiab cov xeb ntawm qhov chaw nce, uas cuam tshuam rau qhov cuam tshuam rau lub siab.Rau qhov loj ntawm cov yeeb nkab steel hauv qhov kev sim no, txoj kab uas hla ntawm cov khoom, D> 1.1-1.5 hli, yeej tsis muaj xeb tshem tawm.D > 0.9 ~ 1.1 hli, lub derusting yog pom tseeb, D <0.9 hli, particle loj me me, lub zog kinetic me me, cov nyhuv derusting tsis zoo;(4) Kev sib raug zoo ntawm amplitude thiab zaus acceleration, amplitude thiab zaus yog raws li nram no: qhov loj ntawm lub amplitude, qhov loj ntawm acceleration, qhov loj ntawm particle kinetic zog, qhov zoo dua cov nyhuv derusting;Nrog rau qhov nce ntawm zaus, lub acceleration nce, tab sis lub amplitude txo, cov nyhuv derusting txo, zaus tus nqi tsawg dhau, thiab cov kev ua tau zoo yog tsawg.Feem ntau hais lus, lub sijhawm ua haujlwm ntev dua, qhov pom tseeb dua qhov cuam tshuam derusting yog.(6) Cov kev taw qhia kev vibration yog ntsug kev vibration, thiab lub zog cuam tshuam ntawm abrasive hais rau ntawm qhov chaw yog siv los tshem tawm cov xeb thiab oxide nplai, ua rau cov seem compressive kev nyuaj siab ntawm qhov chaw, refining cov nplej zom, uas tuaj yeem txhim kho corrosion kuj. ;Kab rov tav kev co siv kev sib txhuam kom tshem tawm cov pob xeb thiab oxide ntawm daim tawv nqaij, ua rau cov residual tensile kev nyuaj siab rau ntawm qhov chaw, uas tsis tshua muaj txiaj ntsig zoo li ntsug kev co.Kev sib xyaw ua ke tuaj yeem txhim kho kev ua haujlwm ntawm derusting thiab scaling, thiab tsim cov residual compressive kev nyuaj siab rau ntawm qhov chaw.
