1.Khoom Taw Qhia luv luv
Covtooj liab hlau tawg weld clad phajyuav tsum tau xa tom qab kev kho cua sov, theem, shearing (los yog txiav), thiab tshem tawm cov tawv nqaij oxide nyob rau saum npoo ntawm cladding. Lub xeev kho cua sov yuav tsum ua raws li cov kev cai ntawm GB150 lossis J4732 cov qauv rau cov khoom siv hauv paus.

2.Mechanical zog
Lub zog sib xyaw ua ke ntawm cov khoom sib txuas ntawm tooj liab hlau tawg vuam clad phaj yuav tsum tsis pub tsawg tshaj 100MPa. Rau ob-sided composite phaj, sib txawv sab cladding cov ntaub ntawv yog tshwj tseg rau kev xeem shear. Tsuas yog kev sim tensile ntawm cov khoom siv hauv paus yuav tsum tau ua rau cov phaj sib xyaw, thiab cov txiaj ntsig kev xeem yuav tsum ua raws li cov kev cai ntawm cov khoom siv hauv paus. Tsuas yog qhov kev ntsuam xyuas cuam tshuam ntawm cov khoom siv hauv paus yuav tsum tau ua rau cov phaj sib xyaw, thiab qhov ntsuas qhov ntsuas kub thiab qhov cuam tshuam lub zog yuav tsum ua raws li cov kev cai ntawm cov khoom siv hauv paus. Yog tias tsis muaj qhov yuav tsum tau ua rau qhov kev ntsuam xyuas cuam tshuam hauv cov txheej txheem cov khoom siv, nws yuav tsis raug rau qhov kev sim cuam tshuam.
3.Khoov kev ua tau zoo
Kev sim rau sab hauv bending (siab rau ntawm qhov chaw ntawm lub cladding) thiab sab nrauv buckling (nruj ntawm qhov chaw ntawm lub cladding) ntawm ib leeg-sided composite phaj thiab txheej dabtsi yog khoov (nruj ntawm qhov chaw ntawm ob hom cladding) ntawm ob- sided composite phaj. Cov txiaj ntsig yuav tsum ua raws li cov kev cai ntawm Table Tsis muaj kev sim khoov yuav tsum tau ua rau cov phaj sib xyaw nrog cov khoom siv hauv paus ua ib feem.
Khoov lub kaum sab xis | Khoov center txoj kab uas hla | xeem tau |
180 degree | Sab hauv dabtsi yog khoov yuav tsum ua raws li cov kev cai ntawm lub hauv paus txheej txheem, thiab sab nraud dabtsi yog khoov d=4a (d=bending center txoj kab uas hla, a yog lub thickness ntawm cov qauv). | Yuav tsum tsis muaj qhov tawg ntawm sab nraud ntawm qhov khoov, thiab yuav tsum tsis muaj delamination ntawm cov khoom sib txuas. |
4. Cov kev cai thiab cov yam ntxwv rau kev tsim cov tooj liab hlau tawg weld clad phaj
1) Kev xav tau:
Cov khoom siv cladding yuav tsum tau annealed. Cov kev cai ntawm lub substrate (xws li tus me nyuam raws li txoj cai, cov cuab yeej tshuaj ntsuam xyuas tus nqi, ultrasonic kuaj, thiab lwm yam.) rau lub substrate, cov phaj sib xyaw nrog qis qis ntawm tus qauv tensile lub zog ntau dua los yog sib npaug rau 540Mpa yuav tsum tau siv tom qab kev tshuaj xyuas. . Thaum cov ntaub ntawv cladding yuav tsum tau welded ua ke, cov txheej txheem tsim nyog yuav tsum tau txiav txim siab los ntawm kev pom zoo ntawm tus neeg muag khoom thiab tus neeg yuav khoom thiab yuav tsum tau qhia hauv chav sib koom ua ke.
2) Yam ntxwv:
Cov hlau cladding thiab cov khoom siv hauv paus yuav tsum tau txuas nrog daim ntawv pov thawj zoo (thawj) ntawm cov chaw tsim khoom. Cov ntsiab lus ntawm cov ntaub ntawv pov thawj zoo yuav tsum ua kom tiav thiab meej thiab stamped nrog kev soj ntsuam zoo ntawm cov khoom tsim khoom. Yog tias tsis muaj daim ntawv pov thawj zoo tshaj plaws, cov chaw tsim khoom phaj sib xyaw yuav tsum tau txais cov ntawv luam ntawm cov ntaub ntawv soj ntsuam thiab tus neeg tuav lub foob ntawm cov khoom siv ntxiv thiab muab khoom, thiab yuav tsum muaj lub luag haujlwm rau qhov tseeb thiab sib xws ntawm cov khoom siv thiab cov khoom siv. daim ntawv pov thawj zoo.
5. Kev soj ntsuam cov cai
Lub rooj sib xyaw ua ke yuav tsum raug tshuaj xyuas los ntawm tus neeg muag khoom lub chaw soj ntsuam zoo. Cov phaj sib xyaw yuav tsum muab xa mus rau hauv cov khoom siv, thiab txhua pawg yuav tsum muaj cov phaj sib xyaw uas tsim los ntawm tib cov khoom sib xyaw ua ke (cov ntaub ntawv npog thiab cov ntaub ntawv hauv paus yog tib hom, tib lub thickness, thiab tib lub xeev xa khoom) thiab tib qhov tawg vuam thiab Kev kho cua sov txheej txheem. Kev kuaj ultrasonic, qhov ntev (tshwj tsis yog cov thickness ntawm cov khoom siv cladding), thiab qhov zoo ntawm qhov chaw yuav tsum tau soj ntsuam ib qho los ntawm ib qho, thiab lwm yam khoom yuav tsum tau soj ntsuam los ntawm batch. Cov khoom tshuaj ntsuam xyuas yuav tsum tau ua los ntawm Demander yuav tsum tau ua raws li cov kev cai ntawm daim ntawv cog lus. Raws li kev pom zoo ntawm tus neeg muag khoom thiab tus neeg yuav khoom, lwm yam khoom tuaj yeem raug tshuaj xyuas
6. Peb qhov zoo
Peb lub tuam txhab yog ib qho ntawm cov kev lag luam tawg tshwj xeeb tau pom zoo los ntawm Baoji Public Security Bureau. Lub tuam txhab muaj ob qhov chaw tawg tawg ua ke, ib qho nrog cov khoom tawg pov tseg tsawg dua 1000 kg thiab ib qho nrog cov khoom tawg pov tseg tsawg dua 2000 kg. Nws yog ib qho ntawm ob peb lub lag luam hauv Baoji uas muaj peev xwm thauj khoom, khaws cia thiab siv cov khoom tawg txaus ntshai.
