1. Txoj kev kho cua sov ntawm cov pa roj carbon steel seamless yeeb nkab yog dab tsi?
Teb: Cov kev kho cua sov feem ntau muaj xws li annealing thiab normalizing. Annealing yog txo hardness thiab txhim kho plasticity, uas yog yooj yim rau kev ua; normalizing yog ua kom cov nplej zom thiab txhim kho cov khoom siv txhua yam ntawm cov yeeb nkab.
2. Txoj kev kho cua sov ntawm high -cov pa roj carbon steel seamless kav dej yog dab tsi?
Teb: High-cov kav dej tshwj xeeb feem ntau siv quenching thiab tempering kev kho mob (quenching + high-temperature tempering), uas tuaj yeem txhim kho lub zog, hardness thiab toughness ntawm cov yeeb nkab, ua kom nws ua tau raws li cov kev xav tau ntawm siab - siab thiab hnyav-load ua haujlwm. Qee cov kav dej kuj xav tau kev ntxhov siab annealing kom tshem tawm cov kev ntxhov siab welding.
3. Dab tsi yog qhov tsis xws luag ntawm carbon steel seamless kav?
Teb: Cov teeb meem tshwm sim muaj xws li cov kab nrib pleb, qhov pits, khawb, cov khoom siv sab hauv, huab cua npuas, thiab cov phab ntsa tsis sib xws. High - cov kav dej tshwj xeeb muaj kev tswj xyuas qhov tsis xws luag, thiab qhov kev tso cai tsis raug yog me dua.
4. Yuav ua li cas kom paub qhov zoo ntawm carbon steel seamless kav?
Teb: Cov kev kuaj pom muaj xws li kev tshuaj xyuas qhov muag (qhov tsis xws luag), ntsuas qhov ntev (inch, phab ntsa thickness), kuaj ultrasonic (sab hauv qhov tsis xws luag), ntsuas tensile (cov khoom siv tshuab), hardness test, thiab tshuaj muaj pes tsawg leeg tsom xam (kom paub meej cov khoom).
5. Lub neej kev pab cuam ntawm cov pa roj carbon steel seamless kav yog dab tsi?
Teb: Raws li kev ua haujlwm ib txwm muaj (nrog rau kev tiv thaiv- kev kho corrosion, qhov kub thiab qhov siab), lub neej kev pab yog 5-10 xyoo; yog siv nyob rau hauv ib puag ncig hnyav (high humidity, corrosion, high temperature), lub neej kev pab cuam yuav luv luv rau 2-5 xyoos.
