Ncaj Seam Welded Yeeb Nkab

1. Board sojntsuam:Tom qab cov hlau phaj siv los tsim cov khoom loj-caliber submerged arc welded ncaj seam steel yeeb nkab nkag mus rau hauv cov kab ntau lawm, tag nrho pawg thawj coj saib xyuas ultrasonic;

2. Ntug milling:ob lub npoo ntawm cov hlau phaj yog ob sab milling los ntawm ntug milling tshuab kom ua tiav cov phaj dav, phaj ntug parallelism thiab groove puab;

3. Pre-bending ntug:lub tshuab ua ntej khoov yog siv los ua ntej khoov ntawm ntug ntawm lub phaj, kom lub ntug ntawm lub phaj muaj qhov curvature ntawm qhov yuav tsum tau ua;

4. Kev tsim:Nyob rau ntawm JCO txoj kev tshuab, thawj ib nrab ntawm lub pre-bent steel phaj yog nias rau hauv "J" zoo tom qab ob peb kauj ruam, thiab tom qab ntawd ib nrab ntawm cov hlau phaj tseem khoov thiab nias rau hauv "C" duab, thiab. Thaum kawg lub "O" zoo ntawm qhov qhib yog tsim

9. X-ray kuaj I:100% X-ray muaj TV tshuaj xyuas ntawm cov welds sab hauv thiab sab nraud, siv cov duab ua haujlwm los xyuas kom meej qhov rhiab heev ntawm qhov tsis zoo;

10. Txoj kab uas hla expansion:tag nrho ntev ntawm lub submerged arc welded ncaj seam steel yeeb nkab tau nthuav dav los txhim kho qhov tseeb qhov tseeb ntawm cov yeeb nkab steel thiab txhim kho qhov kev faib tawm ntawm kev ntxhov siab ntawm cov yeeb nkab steel;

11. Kev ntsuas dej siab:nyob rau hauv lub tshuab ntsuas dej siab kom nthuav dav cov yeeb nkab steel tom qab kev ntsuam xyuas kom ntseeg tau tias cov yeeb nkab steel ua tau raws li cov qauv kev xav tau ntawm kev ntsuas siab, lub tshuab muaj cov ntaub ntawv tsis siv neeg thiab khaws cia;

12. Chamfering:cov yeeb nkab tshuaj ntsuam xyuas yuav raug ua tiav ntawm qhov kawg ntawm cov yeeb nkab kom ua tiav qhov loj ntawm cov yeeb nkab kawg zawj;
