Ntxiv nrog rau kom ua kom muaj cov tshuaj muaj kuab lom thiab cov kws ntsuam xyuas cov neeg siv tshuab, hydrostatic cov kev ntsuam xyuas tau ua ib qho los ntawm ib qho, thiab flaring thiab flatening kev ntsuam xyuas tau ua. Cov. Ib qho ntxiv, muaj qee yam kev xav tau rau microstructure, lis loj me, thiab decarburization txheej ntawm cov txheej txheem steel tiav.
Tensile xeem:
1. Rau cov khoom siv hlau ntawm cov khoom, chaw tsim tshuaj paus yuav tsum ua qhov kev kuaj tensile. Rau cov yeeb nkab welded welded, deponders ntawm cov kev xaiv tsim tsim khoom, cov tshuaj ntsuam Tensile tuaj yeem ua rau cov yeeb nkab steel uas siv los ua cov yeeb nkab lossis perfomed ntawm cov yeeb nkab steel ncaj qha. Kev xeem ua rau cov khoom lag luam tseem siv tau los ua cov khoom ntsuas khoom.
2. Tus ntsuas cov leeg yuav tsum raug xaiv. Thaum ntau qhov kev ntsuam xyuas yuav tsum muaj, tus qauv qhia yuav tsum ua kom pom tseeb tias cov qauv coj tuaj yeem sawv cev rau thaum pib (yog tias muaj cai) thiab ob qho tib si xaus. Thaum ntau qhov kev ntsuam xyuas yuav tsum muaj, tus qauv yuav tsum tau ua los ntawm cov leeg sib txawv tshwj tsis yog tias cov leeg raj thoo thickened los ntawm ob qho kawg ntawm lub raj.
3. Cov qauv ntawm cov yeeb nkab uas tuaj yeem ua rau txhua txoj haujlwm ntawm lub qhov ntawm cov yeeb nkab; Cov yeeb nkab welded yuav tsum tau ua thaum txog 90 ° rau Weld Seam, lossis ntawm kev xaiv ntawm cov chaw tsim khoom. Cov qauv raug coj los ntawm txog ib lub hlis twg ntawm txoj hlua strip.
4. Tsis muaj teeb meem ua ntej thiab tom qab kev sim, yog tias qhov kev npaj coj mus tsis haum lossis muaj cov qauv yuav raug khawb thiab hloov nrog lwm tus qauv ua los ntawm tib lub raj.
5. Yog tias qhov kev sim ntsuas Tensile sawv cev rau cov khoom lag luam tsis tau raws li qhov yuav tsum tau ua tiav, cov chaw tsim khoom yuav siv lwm txoj hlua khi ntawm cov hlab rau kev kuaj xyuas.
Yog tias txhua qhov kev rov ua dua ntawm cov qauv raws li cov cai, cov hlua ntawm cov hlab yog tsim nyog tshwj tsis yog cov raj tsis muaj peev xwm tshwj tsis yog thaum chiv thawj.
Yog tias muaj ntau tshaj ib qho qauv yog pib ua piv txwv lossis ntau dua los yog ntau qhov kev rov ua tiav, cov chaw tsim khoom tuaj yeem tshawb xyuas cov hlua ntawm ib leeg.
Cov khoom tsis lees txais ntawm cov khoom tuaj yeem rov qab kho dua tshiab thiab rov hais dua raws li lub pob tshiab tshiab.
Kaj ntsuam xyuas:
1. Cov zis kuaj yuav tsum yog lub nplhaib sib tw lossis txiav tawm kawg tsis tsawg dua 63.5mm (2-1 / 2in).
2. Cov qauv yuav raug txiav ua ntej kev kho cua sov, tab sis raug rau tib kho cua sov li cov yeeb nkab sawv cev. Yog tias siv cov ntawv xeem tau siv, ntsuas yuav tsum tau los txheeb xyuas qhov kev sib txheeb ntawm cov qauv thiab txoj hlab. Txhua qhov cub hluav taws hauv txhua pob yuav tsum tau tsoo.
3. Qhov hnoos qeev yuav tsum plhatened ntawm ob daim phiaj parallel. Hauv txhua qhov kev ntsuas ntawm cov hnoos qeev, ib lub weld tau pluav ntawm 90 ° thiab lwm qhov flattened ntawm 0 °. Qhov quav yuav tsum pluav kom txog thaum lub raj raj ntsuas raj tau sib cuag. Ua ntej qhov kev ncua deb ntawm cov phiaj parallel yog tsawg dua li cov nqi teev, tsis muaj cov kab nrib pleb lossis kev tawg yuav tsum tshwm sim hauv ib feem ntawm tus qauv. During the entire flattening process, there should be no poor structure, welds not fused, delamination, metal overburning, or metal extrusion.
4. Tsis muaj teeb meem ua ntej thiab tom qab kev sim, yog tias qhov kev npaj coj mus tsis haum lossis muaj cov qauv yuav raug khawb thiab hloov nrog lwm tus qauv ua los ntawm tib lub raj.
5. Yog tias ib qho piv txwv uas sawv cev ntawm lub raj tsis tau raws li cov kev cai tshwj xeeb, cov chaw tsim khoom yuav coj tus qauv los ntawm lub raj rau kev sim tshuaj ntxiv kom txog 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 tshaj 80% ntawm tus thawj ntev. Yog tias ib qho piv txwv ntawm lub raj sawv cev ntawm cov khoom lag luam tsis tau raws li cov kev cai tshwj xeeb, cov chaw tsim khoom yuav siv ob cov khoom ntxiv los ntawm cov khoom lag luam thiab txiav cov qauv rau kev kuaj dua. Yog tias cov txiaj ntsig ntawm cov kev ua tau rov ua tiav txhua qhov ua kom tau raws li cov hlab yog tsim nyog tshwj tsis yog cov raj xub xaiv ua cov qauv. Yog tias ib qho ntawm cov hnoos qeev rov qab tshaj plaws tsis tau raws li cov kev cai tshwj xeeb, cov chaw tsim khoom yuav coj cov leeg ntoo uas tseem tshuav ntawm ib qho. Ntawm qhov kev xaiv ntawm cov chaw tsim khoom, txhua pob ntawm cov hlab tuaj yeem rov kho cua sov thiab rov ua dua li cov hlua tshiab ntawm cov hlab.
Kev Ntsuas Qhov Kev Ntsuas:
1 Yog tias qhov kev txiav txim tau tsau ntawm A10 (SR16), qhov kev sim yog qhov yuav tsum tau ua.
2. Rau casing, 3 hlau kav hlau yuav tsum tau muab los ntawm txhua pob rau kev sim. Qhov kev sim leeg yuav tsum xaiv tau, thiab txoj kev piv txwv yuav tsum ua kom pom lub sijhawm thaum pib thiab ua ntej sab nraub qaum ntawm kev kho cua sov.
3. Charpy V-Meych cuam tshuam kev ntsuas
4. Tsis muaj teeb meem ua ntej thiab tom qab kev sim, yog tias qhov kev npaj coj mus tsis haum lossis muaj cov qauv yuav raug khawb thiab hloov nrog lwm tus qauv ua los ntawm tib lub raj. Cov zis yuav tsum tsis txhob tsuas yog txiav txim rau kev txiav txim siab yooj yim vim tias lawv tsis tau raws li qhov tsawg kawg nkaus uas yuav tsum tau ua.
5. Yog tias qhov tshwm sim ntawm ntau tshaj li ib tus qauv yog qis dua qhov tsawg kawg nkaus nqus lub zog yuav tsum tau, lossis cov qauv ntxiv yuav tsum raug coj los ntawm tib daim thiab rov ua haujlwm. Qhov cuam tshuam rau lub zog ntawm txhua qhov kev txiav txim siab rov qab yuav ntau dua los yog sib npaug ntawm qhov kev xav tau tsawg kawg nkaus.
6. Yog tias cov txiaj ntsig ntawm qee qhov kev sim tsis tau raws li cov cai thiab cov qauv ntxiv yog coj los ntawm txhua tus ntawm peb daim ntawm cov pob. Yog tias tag nrho cov xwm txheej ntxiv tau raws li qhov yuav tsum tau ua, cov batch yog tsim nyog tshwj tsis yog tus uas ua tsis tiav. Yog tias muaj ntau tshaj ib daim ntawv tshuaj xyuas ntxiv tsis tau ua kom tau raws li cov cai, cov chaw tsim khoom yuav tshawb xyuas cov khoom seem ntawm ib qho ntawm ib qho, lossis rov ua dua tshiab rau hauv ib qho tshiab.
7. Yog tias ntau dua ib qho ntawm peb qhov khoom uas yuav tsum tau ua pov thawj rau cov kev tsim nyog tau txais qhov tsis raug tso cai, tsis pub siv cov hlua khi ua ke. Cov chaw tsim khoom yuav xaiv los tshuaj xyuas cov khoom seem uas seem los ntawm daim, lossis rov ua kom rov qab cov pob thiab tshawb xyuas nws hauv cov khoom tshiab.
