Qhov ncaj seam steel yeeb nkab yog steel yeeb nkab nrog longitudinal parallel ntawm weld thiab steel yeeb nkab. Nws yog feem ntau muab faib ua pej xeem hluav taws xob vuam steel kav, vuam nyias phab ntsa kav, transformer txias roj kav, thiab lwm yam. Cov txheej txheem ntawm cov kav hlau ncaj ncaj yog yooj yim, siab ntau lawm efficiency, tsis tshua muaj nqi, thiab kev loj hlob sai.
Qhov ncaj seam steel yeeb nkab yuav muab faib ua high-frequency ncaj steel kav thiab faus arc vuam ncaj seam steel kav raws li cov txheej txheem ntau lawm. faus arc vuam ncaj steel kav yog muab faib ua UOE, RBE, JCOE steel kav, thiab lwm yam raws li lawv txoj kev sib txawv molding. Ntawm no yog cov txheej txheem ntau lawm ntawm cov feem ntau high-frequency ncaj seam steel kav thiab faus arc vuam ncaj seam steel kav.
1. Kev soj ntsuam: Tom qab cov hlau daim hlau siv los tsim loj -caliber faus arc vuam ncaj steel kav rau hauv cov kab ntau lawm, tag nrho pawg thawj coj saib ultrasonic yog ua ntej; kev tsim khoom tuaj yeem ua tau tom qab lees paub qhov kev tsim nyog.
2. Milling ntug: Raws li qhov yuav tsum tau muaj ntawm cov yeeb nkab txoj kab uas hla, muab ob npaug rau-sided milling ntawm ob lub npoo ntawm cov hlau phaj los ntawm lub tshuab milling tuaj yeem ua tiav qhov yuav tsum tau phaj dav, qhov sib npaug ntawm qhov sib npaug, thiab cov duab horn.
3. Pre-bending ntug: Siv lub tshuab ua ntej-bending ua ntej-bending ntawm ntug ntawm lub rooj tsavxwm, kom cov ntug ntawm lub rooj tsavxwm muaj qhov nkhaus nkhaus.
4. Rau molding: Ua ntej ntawm tag nrho cov, ib nrab ntawm cov hlau phaj tom qab lub pre-curved steel phaj yog stamped ntau zaus ntawm lub JCO molding tshuab, nias nws mus rau hauv ib tug "J" zoo li, thiab ces ib nrab ntawm cov hlau phaj. kuj khoov, nias rau hauv "C" duab, thiab thaum kawg tsim qhov qhib qhib. "O" shape
5. Pre-welding: Ua cov txheej txheem ncaj seam vuam steel kav thiab siv roj tiv thaiv vuam (MAG) rau kev txuas txuas ntxiv;
6. Internal welding: Siv cov kab faus rau hauv arc vuam (txog plaub lub xov hlau) nyob rau sab hauv ntawm cov kav hlau ncaj;
7. Sab nraud vuam: Welded rau sab nraud ntawm stitched arc welded steel yeeb nkab nrog siv kem -wire faus arc vuam;
8. Ultrasonic tshuaj xyuas Ⅰ: 100% kev soj ntsuam ntawm lub latch welds thiab welds nyob rau hauv ncaj seam welded steel kav thiab welds;
9. X-ray kuaj Ⅰ: 100% X-ray industrial TV tshuaj xyuas ntawm welded seams sab hauv thiab sab nraud welds yog ua, thiab siv cov duab ua haujlwm los xyuas kom meej qhov rhiab heev ntawm kev kuaj pom;
10. Kev nthuav dav: Qhov ntev ntawm qhov faus arc vuam ncaj seam steel yeeb nkab tau nthuav dav los txhim kho qhov loj thiab qhov tseeb ntawm cov yeeb nkab steel, thiab txhim kho qhov kev faib tawm ntawm kev ntxhov siab hauv cov yeeb nkab steel;
11. Kev ntsuas dej siab: Cov yeeb nkab steel tom qab lub taub tau nthuav dav ntawm lub tshuab ntsuas hydraulic raug tshuaj xyuas kom ntseeg tau tias qhov ntsuas siab ntawm cov yeeb nkab steel kom ua tau raws li tus qauv yuav tsum tau ua. Lub tshuab muaj qhov tsis siv neeg kaw thiab cia muaj nuj nqi;
12. Inverted npoo: Cov yeeb nkab kawg ntawm cov yeeb nkab steel tom qab kev soj ntsuam tau dhau los ua kom tau raws li qhov xav tau ntawm cov yeeb nkab kawg txoj kab nqes loj;
13. Ultrasonic test II: Kev tshuaj xyuas ultrasonic tau ua dua los xyuas qhov tsis xws luag uas cov kav hlau txuas ncaj nraim tuaj yeem tsim tom qab txoj kab uas hla thiab dej siab;
14.X xov tooj cua Examination II: Ua X-ray industrial TV tshuaj xyuas thiab cov raj welds rau steel kav tom qab txoj kab uas hla thiab hydraulic xeem;
15. Tube kawg sib nqus hmoov kuaj: ua qhov kev tshuaj xyuas no kom pom cov raj-kawg tsis xws luag;
16. Kev tsis ncaj ncees: Cov kav hlau uas tsim nyog tau ua tiav raws li cov neeg siv khoom xav tau.
