Kauv steel yeeb nkabyog tsim los ntawm steel kauj, extrusion tsim nyob rau hauv ib txwm kub, ces coj lub tshuab ntawm ob lub xaim thiab ob-ntsej muag submerged-arc welded.
Kauv steel yeeb nkab, tseem hu ua kauv los yog helix kauv steel yeeb nkab, yog cov hlau tsis muaj cov pa roj carbon tsawg lossis cov hlau tsis tshua muaj hlau ntawm ib lub kaum ntse ntse (hu ua lub kaum sab xis molding) dov rau hauv lub raj, thiab lub raj yog ua los ntawm cov pob qij txha. Nws tuaj yeem tsim nrog ib txoj hlua nqaim ntawm txoj kab uas hla loj.
Thaum lub sij hawm molding txheej txheem ntawm kauv welded steel yeeb nkab, steel phaj muaj cov yam ntxwv deformation thiab lub teeb residual kev nyuaj siab, yog li cov nto tsis muaj khawb. Kauv steel yeeb nkab muaj qhov hloov pauv tau yooj yim dua thiab txoj kab uas hla, tshwj xeeb tshaj yog hauv kev ua cov kav dej tuab tuab nrog me me lossis nruab nrab aperture, cov txheej txheem no muaj qhov zoo sib xws hauv kev txaus siab rau koj cov kev xav tau.
1. unwinding board sojntsuam: Tom qab nkag mus rau lub unwinding phaj ntau lawm kab, thawj tag nrho-board ultrasonic kuaj.
2. Leveling Milling: Lub tiaj tus steel anvil tshuab kom tus thawj curl, thiab tom qab ntawd los ntawm ntug milling tshuab rau ob sab steel milling, thiaj li ua tau raws li qhov yuav tsum tau ntawm lub phaj dav, phaj ntug parallelism thiab zawj duab.
3. shear molding: steel phaj ntau lawm kab raws ntug txheej ntawm cov kauv curl rau hauv ib lub raj.
4. taub qab txiav: ob-sided submerged arc vuam siv cov cuab yeej siv siab ua ntej vuam, vuam sab hauv, vuam sab nraud. Ion ko taw txiav rau specification ntev welded kauv yeeb nkab siv thiab lwm yam.
5. Kev tshuaj xyuas qhov muag: los ntawm cov kws tshaj lij thiab cov neeg ua haujlwm ua haujlwm rau qee qhov kev ntsuas tsis zoo yuav tsum tau kuaj xyuas.
6. Ultrasonic flaw detection: sab hauv thiab sab nraud weld thiab vuam ntawm ob sab ntawm cov khoom siv hauv paus 100 feem pua kev tshuaj xyuas.
7. X-ray nrhiav pom: sab hauv thiab sab nraud welds 100 feem pua X-ray muaj TV saib xyuas cov duab ua haujlwm kom ntseeg tau tias kev siv kev tshawb pom rhiab heev.
8. Kev ntsuas siab: cov kauv steel yeeb nkab hydrostatic testing tshuab-los ntawm cov hauv paus kev sim kom ntseeg tau tias cov yeeb nkab ntsuas siab ua tau raws li cov qauv xav tau.
9. chamfering tiaj tus taub hau: kauv hlau yeeb tshuaj ntsuam xyuas tom qab cov yeeb nkab kawg ua, kom tau raws li qhov yuav tsum tau ntawm cov yeeb nkab kawg beveling loj
10. Kev tshuaj xyuas zaum kawg: kev kuaj xyuas ultrasonic thiab X-ray dua thiab muab kauv steel yeeb nkab xaus kev tshuaj xyuas qhov sib nqus, xyuas seb puas muaj teeb meem thiab vuam yeeb nkab xaus qhov tsis xws luag.
11. oiled marking: kauv steel yeeb nkab tom qab dhau tau oiled los tiv thaiv corrosion, thiab raws li tus neeg siv yuav tsum tau rau kev kos.
