2.Qhov ntug milling: ob npaug ntawm ob txoj kab milling ntawm ob lub npoo ntawm lub phaj steel los ntawm ib lub ntug milling tshuab kom ua tiav cov phaj xav tau dav, phaj ntug parallelism thiab duab puab;
3. Ua ntej khoov: Siv lub tshuab ua ntej khoov los khoov ua ntej lub ntug ntawm lub rooj tsav xwm kom ntug ntawm lub rooj tsavxwm muaj qhov xav kom tuaj yeem nkhaus;
4. Txoj Kev Ua: Hauv JCO sib sau tshuab, ib nrab ntawm cov pre-bent steel phaj tau nias rau hauv" J" cov duab los ntawm ntau kauj ruam thiab nias, thiab tom qab ntawd ces ib nrab ntawm cov phaj steel kuj tseem yog khoov thiab nias rau hauv" C" puab, thiab tom qab ntawv qhib tau tsim" O" daim duab;
5. Ua ntej welding: Koom nrog tsim qhov ntev ntev txuas welded steel yeeb nkab thiab siv cov roj thaiv kev siv vuam (MAG) rau kev vuam tas mus li;
6. Sab hauv vuam: txais ntev ntev-ntau cov hlau xaim subcous arc vuam (ntau dua plaub lub xov hlau) txhawm rau txuas rau sab hauv sab ntawm ncaj ncaj hlau yeeb;
7. Sab nraud vuam: siv cov khoom sib txuas ntev-hlau ntau submerged arc vuam mus rau qhov chaw txuas rau sab nraud ntawm qhov ntev ntawm qhov ntev ua haujlwm subcc arc welded steel yeeb;
8. Kev soj ntsuam ultrasonic Kuv: 100% kev soj ntsuam ntawm cov hlau txuas sab hauv thiab sab nraud ntawm qhov txuas ntawm qhov ntev nrog welded steel yeeb nkab thiab lub hauv paus cov ntaub ntawv ntawm ob sab ntawm weld;
9. Xoo hluav taws xob xoo hluav taws xob Ⅰ: 100% Xoo hluav taws xob xaim hluav taws xob TV kuaj ntawm cov khoom siv sab hauv thiab sab nraud, siv lub tshuab ua cov duab ua haujlwm kom paub meej txog qhov ua tsis tau zoo;
10. Txoj kab uas hla kev nthuav dav: nthuav tag nrho ntev ntawm qhov submerged arc welded ncaj seam steel yeeb nkab txhawm rau txhim kho lub qhov ntev ntawm qhov tseeb ntawm cov yeeb nkab steel thiab txhim kho kev faib tawm sab hauv kev ntxhov siab ntawm cov yeeb nkab steel;
11. Kev ntsuam xyuas hydrostatic: Lub txhab hlau txuas ntxiv tau kuaj xyuas ib qho los ntawm ib qho ntawm lub tshuab kuaj hydrostatic kom paub tseeb tias cov yeeb nkab steel ua tau raws li qhov ntsuas siab yuav tsum tau ua los ntawm cov qauv. Lub tshuab tsis siv neeg kaw thiab cia cov haujlwm;
12. Chamfering: Txheej txheem cov yeeb nkab tas ntawm cov kav hlau uas tau dhau qhov kev kuaj xyuas kom tau raws li qhov yuav tsum tau ua kom kawg cov kav hlau;
13. Kev tshuaj xyuas ultrasonic Ⅱ: Ua ultrasonic kev soj ntsuam dua ib qho los xyuas ib qho los xyuas qhov ua kom puas qhov cuam tshuam ntawm qhov ntev-txuas welded steel yeeb nkab tom qab qhov taub loj tuaj thiab dej siab;
14. Xoo hluav taws xob xoo hluav taws xob tshuaj ntsuam Ⅱ: Kev ntsuas hluav taws xob xoo hluav taws xob hauv TV thiab cov yeeb yaj kiab kawg weld zaj duab xis ntawm cov yeeb nkab steel tom qab nthuav thiab kuaj hydraulic;
15. Tube kawg nqus cov khoom lag luam soj ntsuam: nqa tawm qhov kev kuaj xyuas no kom pom cov leeg kawg qhov tsis xws luag;
16. Los tiv thaiv corrosion thiab txheej: Cov yeeb yaj kiab uas tsim nyog muaj cov kav hlau tiv thaiv kev tiv thaiv thiab txheej ua raws li tus neeg siv khoom.
