Q: Cov teeb meem tshwm sim zoo li cas hauv cov txheej txheem txias txias?
A: Sckes \/ abarrasions: Tawm lossis flaky khawb tshwm rau ntawm saum npoo ntawm cov kab txaij, uas tuaj yeem nkag rau tag nrho cov tuab nyob rau hauv cov neeg mob hnyav.
Cov menyuam cim (indentations): perientic concave thiab convex cov cim tshwm rau saum npoo ntawm sawb, sib haum rau qhov kev ncig ntawm cov menyuam.
Adhesion (cov menyuam cov nplaum): tom qab dov, cov txheej strip ua raws txhua tus thiab yog qhov nyuaj cais.
Q: Cov teeb meem tshwm sim ntawm cov teeb meem zoo li cas?
A: Sckes \/ Aplasions: Muaj cov protrusions lossis cov khoom txawv teb chaws ntawm cov yob, coj cov phiaj, thiab ncaj chais; Kev nro tsis txaus ua rau cov sawb mus rau kev rhuav tshem thiab txhuam tawm tsam cov khoom siv; Cov neeg tsis tiav tsis tiav ua rau cov neeg hlau nyob oxide mus poob tom qab dov.
Cov cim rau cov menyuam (indentations): hnav, tawg, lossis cov khib nyiab hlau nyob saum npoo ntawm cov menyuam; Cov khoom txawv teb chaws raug nias rau hauv cov menyuam nyob saum npoo thaum lub sijhawm dov (xws li cov ntawv sau hlau (lubricating impurities).
Adhesion (dov adhesion): lub rolling ceev yog dhau lossis txo tus nqi yog ntau dhau, uas ua rau kub nyob hauv qhov kub thiab kub nyob hauv ib lub zog; Tsis txaus lubrication, hlau sib chwv ncaj qha thiab koom tes.
Q: Cov kev daws teeb meem rau cov teeb meem tshwm sim ib txwm muaj li cas?
A: Sckes \/ Aplasions: Khij cov menyuam qhov raug ua tsis tu ncua, zom lossis hloov cov menyuam hauv lub sijhawm; Kho cov nro tswj cov kab ke kom ntseeg tau tias muaj peev xwm ua haujlwm ntawm sawb; Txhim kho tus txheej txheem pickling kom ntseeg tau tias qhov chaw huv.
Cov Menyuam Mark (Indentation): Siv cov khoom siv-resistant (xws li high-chromium cam khwb cia hlau) los tsim cov zaub mov, thiab ua kom muaj qhov tsis pom zoo; ntxiv dag zog rau lub lim ntawm lubrication system thiab siv cov roj rolling huv.
Adhesion (dov adhesion): txo cov dov nrawm lossis tswj hwm tus nqi txo nyob rau theem; Txhawb cov roj nplua nyeem lossis hloov siab-viscosity dov roj.
Q: Dab tsi yog qhov ua rau thiab cov kev daws teeb meem rau kev tsis sib xws thaum lub sijhawm txias?
A: Ua rau: tsis sib luag yob hnav lossis tsis sib xws los nthuav tawm; Tsis siv neeg thickness tswj (AGC) cov lus teb kev teb lag lossis sensor yuam kev.
Kev Ntsuas: Siv cov thermal yob puab puab kho tshuab (xws li segmented cua txias yob); Hloov kho cov txheej txheem AGC thiab siv cov high-precision laser theriD tuab site rau lub sijhawm rov qab.
Q: Dab tsi ntawm cov teebmeem tuaj yeem ua haujlwm ntau dhau harterening yooj yim tsim tau?
A: Pej: tom qab dov tawm, cov khoom siv zog yog dhau lawm, cov yas yog qhov kev ua kom tsis txaus, thiab kev ua tiav yog ib qho kev ua kom tawg.
Cause: tus nqi txo qis yog ntau dhau, thiab analmediate anealing tsis nqa tawm nyob rau lub sijhawm; Tsis raug lwm cov txheej txheem annealing (xws li tsawg heev kub, tsis muaj sijhawm).
Kev daws: Tsim tau tsim kho cov yob hla thiab tswj hwm tus nqi txo ntawm txhua daim ntawv hla; Ua kom zoo dua lub annealing system raws li cov ntaub ntawv qib (xws li nce anealing kub lossis ncua sij hawm rwb thaiv tsev).
