1. Lub npe tag nrho ntawm 16Mn carbon steel seamless yeeb nkab yog dab tsi?
Teb: 16Mn carbon steel seamless yeeb nkab tseem hu ua Q345B seamless yeeb nkab (hauv Suav qauv). Nws yog cov hlau tsis tshua muaj siab - lub zog carbon steel yeeb nkab nrog cov ntsiab lus ntawm manganese li ntawm 1.2% -1.6%, uas tuaj yeem txhim kho lub zog thiab tawv ntawm cov yeeb nkab.
2. Dab tsi yog cov txheej txheem dav dav ntawm carbon steel seamless kav?
Teb: Qhov dav dav dav dav (OD) cov lus qhia tshwj xeeb ntawm 10mm txog 630mm. Rau cov qib zoo tib yam, cov kev qhia tshwj xeeb yog 15mm, 20mm, 25mm, 32mm, thiab lwm yam; rau qib siab -cov lus qhia tshwj xeeb, qhov loj ntawm sab nraud (xws li 108mm, 159mm, 219mm) muaj ntau dua.
3. Dab tsi yog phab ntsa thickness ntau ntawm carbon steel seamless kav?
Teb: Phab ntsa thickness (WT) yog li ntawm 1.5mm txog 60mm. Cov qib qub feem ntau yog siv rau nyias - cov kav dej (1.5mm-10mm), thaum qib siab -cov lus qhia tshwj xeeb (xws li 45#, 16Mn) feem ntau yog siv rau cov kav dej tuab (10mm-60mm) kom ua tau siab dua.
4. Dab tsi yog qhov txawv ntawm kub- dov thiab txias - kos carbon steel seamless kav?
Teb: Kub- dov seamless kav yog tsim los ntawm cua sov lub billet mus rau ib tug kub thiab dov, nrog loj txheej kab thiab phab ntsa thickness kam rau ua, haum rau kev siv dav dav; txias-cov kav dej seamless kos tau ua tiav ntawm chav tsev kub, nrog kev ua haujlwm siab, du nto, thiab tsim nyog rau lub sijhawm uas xav tau siab ntawm qhov loj thiab qhov zoo.
5. Can 20 # carbon steel seamless yeeb nkab yuav welded?
Teb: Yog. 20# carbon steel yog tsawg carbon steel nrog zoo weldability. Nws tuaj yeem welded los ntawm arc vuam, roj vuam thiab lwm txoj hauv kev yam tsis muaj preheating (nyob rau hauv ib txwm muaj), thiab vuam zoo yog ruaj khov.
