Ntxiv nrog rau kev ua kom muaj cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab, kev sim hydrostatic tau ua ib qho los ntawm ib qho, thiab kev sim flaring thiab flattening yog ua. . Tsis tas li ntawd, muaj qee qhov yuav tsum tau ua rau microstructure, grain loj, thiab decarburization txheej ntawm cov yeeb nkab steel tiav.
Tensile Test:
1. Rau cov khoom siv hlau ntawm cov khoom, cov chaw tsim khoom yuav tsum ua qhov ntsuas tensile. Rau cov elecrtrice welded yeeb nkab, depondeds ntawm cov chaw tsim tshuaj paus xaiv, tensile xeem yuav ua tau rau ntawm steel phaj uas siv los ua yeeb nkab los yog perfomred rau steel yeeb nkab ncaj qha. Ib qho kev sim ua ntawm cov khoom siv kuj tuaj yeem siv los ua cov khoom kuaj.
2. Cov raj kuaj yuav tsum raug xaiv xaiv. Thaum xav tau ntau qhov kev sim, cov qauv ntsuas yuav tsum xyuas kom meej tias cov qauv coj tuaj yeem sawv cev rau qhov pib thiab qhov kawg ntawm lub voj voog kho cua sov (yog tias tsim nyog) thiab ob qhov kawg ntawm lub raj. Thaum xav tau ntau yam kev ntsuam xyuas, tus qauv yuav tsum raug coj los ntawm cov raj sib txawv tshwj tsis yog tias cov qauv tuab tuab tuaj yeem raug coj los ntawm ob qho kawg ntawm lub raj.
3. Cov qauv seamless yeeb nkab tuaj yeem coj los ntawm txhua txoj haujlwm ntawm qhov ncig ntawm cov yeeb nkab; cov qauv welded yeeb nkab yuav tsum tau muab coj los ntawm li 90 ° mus rau lub vuam seam, los yog ntawm qhov kev xaiv ntawm cov chaw tsim khoom. Cov qauv raug coj los ntawm kwv yees li ib feem peb ntawm lub strip dav.
4. Tsis muaj teeb meem ua ntej thiab tom qab kev sim, yog tias cov qauv npaj tau pom tias muaj qhov tsis zoo lossis tsis muaj cov ntaub ntawv tsis cuam tshuam rau lub hom phiaj ntawm kev sim, cov qauv yuav raug muab pov tseg thiab hloov nrog lwm cov qauv ua los ntawm tib lub raj.
5. Yog tias qhov kev ntsuas tensile uas sawv cev rau ib pawg ntawm cov khoom tsis ua raws li qhov yuav tsum tau ua, cov chaw tsim khoom tuaj yeem siv lwm 3 lub raj los ntawm tib lub batch ntawm cov raj rau kev tshuaj xyuas dua.
Yog tias tag nrho cov kev kuaj xyuas ntawm cov qauv ua tau raws li qhov yuav tsum tau ua, cov batch ntawm cov raj tsim nyog tshwj tsis yog cov raj tsis tsim nyog uas yog thawj zaug kuaj.
Yog tias ntau tshaj ib tus qauv yog thawj zaug kuaj lossis ib lossis ntau qhov qauv rau kev kuaj xyuas tsis tau raws li qhov yuav tsum tau ua, cov chaw tsim khoom tuaj yeem kuaj xyuas cov hlab ntsha ntawm ib qho los ntawm ib qho.
Cov khoom tsis lees txais cov khoom tuaj yeem rov ua dua thiab rov ua dua tshiab raws li cov khoom tshiab.
Flattening Test:
1. Cov qauv kuaj yuav tsum yog lub nplhaib kuaj lossis qhov kawg txiav tsis pub tsawg dua 63.5mm (2-1 / 2in).
2. Cov qauv yuav raug txiav ua ntej kev kho cua sov, tab sis raug rau kev kho cua sov tib yam li cov yeeb nkab sawv cev. Yog tias siv batch xeem, ntsuas yuav tsum tau coj los txheeb xyuas qhov kev sib raug zoo ntawm cov qauv thiab cov qauv coj mus kuaj. Txhua qhov cub hauv txhua pawg yuav tsum tau crushed.
3. Cov qauv yuav tsum flattened ntawm ob daim hlau sib txuas. Nyob rau hauv txhua txheej ntawm flattening test specimens, ib tug weld yog flattened ntawm 90 ° thiab lwm yam flattened ntawm 0 °. Cov qauv yuav tsum flattened kom txog thaum lub raj phab ntsa nyob rau hauv kev sib cuag. Ua ntej qhov kev ncua deb ntawm cov paib sib npaug yog tsawg dua li tus nqi teev, tsis muaj cov kab nrib pleb lossis tawg yuav tsum tshwm sim hauv ib feem ntawm cov qauv. Thaum lub sij hawm tag nrho cov txheej txheem flattening, yuav tsum tsis muaj cov qauv tsis zoo, welds tsis fused, delamination, hlau overburning, los yog hlau extrusion.
4. Tsis muaj teeb meem ua ntej thiab tom qab kev sim, yog tias cov qauv npaj tau pom tias muaj qhov tsis zoo lossis tsis muaj cov ntaub ntawv tsis cuam tshuam rau lub hom phiaj ntawm kev sim, cov qauv yuav raug muab pov tseg thiab hloov nrog lwm cov qauv ua los ntawm tib lub raj.
5. Yog tias ib qho qauv uas sawv cev rau lub raj tsis tau raws li qhov yuav tsum tau ua, cov chaw tsim khoom tuaj yeem nqa cov qauv los ntawm tib qhov kawg ntawm lub raj rau kev kuaj ntxiv kom txog rau thaum cov kev xav tau. Txawm li cas los xij, qhov ntev ntawm cov yeeb nkab tiav tom qab kuaj yuav tsum tsis pub tsawg dua 80% ntawm qhov ntev ntawm qhov qub. Yog tias ib qho qauv ntawm ib lub raj uas sawv cev rau ib pawg ntawm cov khoom tsis tau raws li qhov yuav tsum tau ua, cov chaw tsim khoom tuaj yeem nqa ob lub raj ntxiv los ntawm cov khoom batch thiab txiav cov qauv rau kev kuaj rov qab. Yog tias cov txiaj ntsig ntawm cov kev ntsuas rov qab no tag nrho ua tau raws li qhov yuav tsum tau ua, cov batch ntawm cov raj tsim nyog tshwj tsis yog lub raj tau xaiv los ua tus qauv. Yog tias ib qho ntawm cov qauv rov kuaj dua tsis ua raws li qhov yuav tsum tau ua, cov chaw tsim khoom tuaj yeem coj cov raj seem ntawm cov batch ib los ntawm ib qho. Ntawm qhov kev xaiv ntawm cov chaw tsim khoom, txhua pawg ntawm cov raj tuaj yeem rov kho dua thiab rov ua dua tshiab raws li cov kab tshiab.
