Kauv submerged arc weldedsteel yeeb nkab (SSAW)yog ib hom loj-inch welded yeeb nkab uas yog dav siv nyob rau hauv cov roj thiab roj kis, dej, thiab lwm yam lag luam. Cov txheej txheem ntawm kev ua SSAW steel yeeb nkab muaj ob peb kauj ruam, nrog rau kev npaj coil, ntug milling, vuam, sizing, thiab kev sim.
1, Thawj kauj ruam yog kauj ruam npaj. Hlau coils yog unwound thiab flattened ua ntej lawv raug xa mus los ntawm ib tug ntug zeb, uas tshem tawm tej burrs los yog ntse npoo ntawm ob sab ntawm lub kauj. Qhov no ua kom cov ntug ntawm lub kauj yog zoo kawg nkaus ncaj thiab haum rau vuam.
2, Tom ntej no, cov coils tau pub rau hauv lub tshuab uas ua rau lawv mus rau hauv ib lub voj voog. Cov npoo ntawm lub kauj yog welded ua ke siv submerged arc vuam, uas yuav dhau los ntawm cov hluav taws xob tam sim no los ntawm cov hlau thiab vuam hlau los ua ib qho txuas txuas ntxiv.
3, Tom qab vuam tiav lawm, cov yeeb nkab tau dhau los ntawm cov txheej txheem ntawm cov yob los xyuas kom meej tias nws ua tau raws li lub cheeb thiab phab ntsa thickness. Cov txheej txheem sizing kuj pab txhim kho lub roundness thiab straightness ntawm cov yeeb nkab.
4, Thaum kawg, cov yeeb nkab tau raug rau ntau yam kev ntsuam xyuas los xyuas qhov tsis xws luag thiab xyuas kom meej tias nws ua tau raws li cov qauv xav tau. Cov kev sim no suav nrog kev kuaj hydrostatic, kuaj ultrasonic, thiab kuaj X-ray.
Zuag qhia tag nrho, cov txheej txheem ntawm kev ua SSAW steel yeeb nkab yog cov txheej txheem nyuaj thiab meej uas yuav tsum muaj cov neeg ua haujlwm txawj thiab cov tshuab siab heev. Cov khoom ua tau yog ruaj khov, txhim khu kev qha, thiab siv dav hauv ntau daim ntawv thov.
