(3) Kub dov feem ntau siv cov ingots loj thiab cov dov loj txo, uas tsis tsuas yog txhim kho kev ua tau zoo, tab sis kuj tsim cov xwm txheej rau kev ua kom nrawm nrawm thiab paub txog qhov txuas ntxiv thiab automation ntawm cov txheej txheem dov. Qhov tsis zoo ntawm kub dov ntawm tooj liab strips: (1) Tom qab kub dov, cov khoom tsis yog xim hlau (tsuas yog sulfides, oxides, thiab silicates) hauv cov hlau yog nias rau hauv cov ntawv nyias, ua rau delamination (interlayering). Delamination zoo heev deteriorates tensile zog ntawm cov hlau raws li thickness kev taw qhia thiab tej zaum yuav ua rau interlaminar tearing raws li cov weld shrinks. Cov kab mob hauv zos uas raug cuam tshuam los ntawm weld shrinkage feem ntau nce mus txog ob peb zaug ntawm cov ntsiab lus tawm los, uas yog ntau dua li cov kab mob tshwm sim los ntawm kev thauj khoom. (2) Cov kev ntxhov siab uas tshwm sim los ntawm qhov txias tsis sib xws. Residual stress yog qhov kev ntxhov siab nyob hauv tus kheej uas tsis muaj zog sab nraud. Kub-kuav los tiag steel seem ntawm ntau seem muaj xws li residual stress. Feem ntau, qhov loj dua qhov loj ntawm ntu ntu ntawm ntu steel, qhov ntau dua qhov kev ntxhov siab seem. Txawm hais tias residual kev ntxhov siab yog qhov sib npaug ntawm tus kheej, nws tseem muaj qee yam cuam tshuam rau kev ua haujlwm ntawm cov hlau nyob rau hauv qhov kev txiav txim ntawm sab nraud rog. Piv txwv li, nws yuav muaj kev cuam tshuam tsis zoo rau kev deformation, stability, qaug zog, thiab lwm yam. (3) Kub dov tsis tuaj yeem tswj cov khoom siv kho qhov muag kom raug, thiab cov qauv thiab cov khoom ntawm cov khoom kub dov tsis tuaj yeem sib xws. Nws lub zog Performance index yog qis dua txias ua hauj lwm hardened khoom, tab sis siab tshaj tag nrho annealed khoom; nws cov plasticity Performance index yog siab dua cov khoom txias ua hauj lwm hardened, tab sis qis dua tag nrho cov khoom annealed. (4) Lub thickness thiab qhov loj ntawm cov khoom kub dov yog qhov nyuaj rau kev tswj, thiab kev tswj qhov tseeb yog qhov tsis zoo; Qhov saum npoo ntawm cov khoom kub dov yog rougher dua li cov khoom txias dov, thiab Ra tus nqi feem ntau yog 0.5 txog 1.5 μm. Yog li ntawd, cov khoom kub dov feem ntau yog siv los ua qhov khoob rau kev ua haujlwm txias. Kev daws rau cov teeb meem tshwm sim nrog tooj liab strips: 1. Cov kev daws teeb meem rau discoloration ntawm tooj liab strips (1) Tswj cov concentration ntawm cov kua qaub thaum pickling. Nyob rau hauv cov ntaub ntawv ntawm ntxuav tawm cov oxide txheej ntawm qhov chaw ntawm lub annealed tooj liab sawb, ib tug siab acid concentration tsis muaj kev nkag siab. Ntawm qhov tsis sib xws, yog tias cov concentration siab dhau lawm, cov kua qaub seem uas txuas rau saum npoo ntawm cov tooj liab tsis yooj yim los ntxuav, thiab nws ua rau kom muaj kuab paug ntawm cov dej ntxuav, ua rau cov concentration ntawm cov kua qaub seem hauv cov dej ntxuav. siab dhau heev lawm, ua rau cov kab hlau ntxuav tau zoo dua tuaj yeem hloov xim. Yog li ntawd, thaum txiav txim siab qhov concentration ntawm cov tshuaj pickling, cov hauv paus ntsiab lus yuav tsum tau ua raws li nram no: nyob rau hauv lub hauv paus ntsiab lus hais tias cov oxide txheej nyob rau saum npoo ntawm tooj liab sawb yuav tsum tau ntxuav, lub concentration yuav tsum tau txo kom ntau li ntau tau. (2) Tswj cov conductivity ntawm cov dej ntshiab. Tswj cov dej ntshiab, uas yog, tswj cov ntsiab lus ntawm cov khoom tsis zoo xws li chloride ions hauv dej ntshiab. Feem ntau, nws muaj kev nyab xeeb los tswj cov conductivity qis dua 50μS / cm. (3) Tswj cov conductivity ntawm cov dej kub ntxuav thiab passivation tus neeg sawv cev. Qhov nce hauv conductivity ntawm dej kub ntxuav thiab passivation tus neeg sawv cev tsuas yog los ntawm cov residual acid coj los ntawm khiav tooj liab sawb. Yog li ntawd, thaum ua kom ntseeg tau qhov zoo ntawm cov dej ntshiab rau kev ntxuav, tswj cov conductivity txhais tau tias tswj cov kua qaub seem. Raws li ntau qhov kev sim, nws muaj kev nyab xeeb los tswj cov dej kub ntxuav thiab tus neeg sawv cev passivation hauv qab 200 μS / cm feem. (4) Xyuas kom cov sawb tooj liab qhuav. Ib feem muab lub qhov hluav taws xob coiling ntawm lub tshuab cua cushion rauv, thiab siv lub tshuab dehumidifier thiab cua txias hauv ib feem ntawm cov khoom siv los tswj cov av noo thiab qhov kub thiab txias thaum lub sij hawm tooj liab coiling nyob rau hauv ib qho chaw. (5) Siv tus neeg sawv cev passivation kom passivate. Feem ntau cov nroj tsuag ua tooj liab tam sim no siv benzotriazole, los yog BTA (molecular mis: C6H5N3) ua tus neeg sawv cev passivating. Kev xyaum tau ua pov thawj tias nws yog ib qho yooj yim rau siv, kev lag luam thiab kev ua haujlwm passivation tus neeg sawv cev. Thaum cov tooj liab hla dhau los ntawm BTA cov tshuaj, cov oxide zaj duab xis nyob rau saum npoo reacts nrog BTA los tsim ib tug ntom complex, uas tiv thaiv cov tooj liab matrix. 2. Txoj kev daws teeb meem rau shear indentation ntawm lub sawb tooj liab yog los tiv thaiv cov shearing indentation. Nws yog ib qho tseem ceeb uas yuav tsum xaiv ib rab riam tsim nyog thiab cov kab sib txawv ntawm cov roj hmab tev nplhaib raws li cov thickness, softness thiab hardness ntawm cov sawb; lub hardness ntawm cov roj hmab tev nplhaib ua tau raws li qhov yuav tsum tau muaj rau kev siv cov txiav sawb; Thaum qhov dav ntawm qhov txiav sawb me me, lub thickness ntawm cov riam ncig yuav tsum raug xaiv kom tsim nyog los ua kom qhov dav ntawm cov roj hmab tev nplhaib.
