1. Ua ntej xeb tshem tawm ntawmtxias kos steel kav, ntau yam pom av ntawm qhov chaw yuav tsum tau muab tshem tawm ua ntej, thiab tom qab ntawd cov kuab tshuaj los yog tshuaj ntxuav yuav tsum tau siv los tshem tawm cov roj.
2. Siv lub tungsten steel shovel tshem tawm cov cheeb tsam loj ntawm xeb.
3. Siv cov txhuam txhuam thiab txhuam txhuam kom tshem cov xeb ntawm cov npoo thiab cov ces kaum ntawm cov yeeb nkab steel.
4. Siv cov ntaub ntawv tshem tawm cov protrusions xws li vuam slag thiab ntau yam burrs los ntawm steel kav.
5. Cov kav dej txias txias yuav tsum tau ntxuav nrog cov ntaub xuab zeb thiab steel hlau txhuam.
(1) Cov yeeb nkab steel carbon steel muaj kuab paug: khawb los ntawm kev sib cuag nrog cov pa roj carbon steel qhov chaw ntawm lub hauv paus roj teeb nrog corrosion nruab nrab, uas ua rau electrochemical corrosion.
(2) Kev txiav cov yeeb nkab txias txias: qhov sib txuas ntawm cov khoom siv xeb xws li txiav slag thiab spatter thiab tsim cov roj teeb tseem ceeb nrog cov nruab nrab corrosive yuav ua rau electrochemical corrosion.
(3) Kev kho qhov ci: qhov muaj pes tsawg leeg thiab cov qauv metallographic ntawm cov nplaim hluav taws kub hauv cheeb tsam hloov tsis sib xws, tsim cov roj teeb tseem ceeb nrog cov nruab nrab corrosion, ua rau electrochemical corrosion.
(4) steel yeeb nkab vuam: lub cev tsis xws luag (undercut, pore, tawg, tsis tiav fusion, tsis tiav kev nkag, thiab lwm yam) thiab tshuaj tsis xws luag (coarse grain, pluag chromium ntawm grain ciam, cais, thiab lwm yam) nyob rau hauv lub vuam cheeb tsam daim ntawv Primary roj teeb nrog lub nruab nrab corrosion los tsim electrochemical corrosion.
(5) Cov khoom siv: tshuaj lom neeg tsis xws luag (tsis sib xws, S, P impurities, thiab lwm yam) thiab qhov chaw ntawm lub cev tsis xws luag (looseness, xuab zeb qhov, tawg, thiab lwm yam) ntawm cov yeeb nkab steel yog qhov tsim nyog rau kev tsim cov roj teeb hauv lub hauv paus nrog corrosion nruab nrab thiab generating. electrochemical corrosion.
(6) Passivation: Tsis zoo acid pickling passivation tshwm sim nyob rau hauv tsis sib xws los yog nyias passivation zaj duab xis nyob rau saum npoo ntawm txias drawn steel kav, uas yog heev rau electrochemical corrosion.
Hauv cov ntsiab lus, qhov no yog cov ntsiab lus ntawm cov kev paub txog kev decontamination thiab tshuaj lom neeg kev kho mob ntawm cov kav dej txias txias.Kuv ntseeg tias txhua tus muaj kev kawm thiab kev nkag siab ntxiv.Yog tias koj tseem xav kawm paub ntxiv, thov ua raws li peb txuas ntxiv.
