Khoom Description
Hauv kev lag luam roj cylinder, "siab zog ua ke nrog lub zog sib dua" yeej ib txwm yog lub hom phiaj tseem ceeb. Cov khoom siv tsoos feem ntau xav tau cov phab ntsa tuab ntxiv los txhim kho lub zog; Txawm li cas los xij, qhov no ua rau hnyav hnyav thiab nqi thauj mus los. Piv txwv li,HP345- steel muaj zogtsim tshwj xeeb rau lub tog raj kheej roj -leverages advanced cov khoom tsim thiab txheej txheem optimization kom ua tau zoo txo qhov hnyav thaum muaj kev ruaj ntseg tag nrho.
| Yam khoom | Tus nqi |
|---|---|
| Yield zog | Ntau dua lossis sib npaug li 345 MPa |
| Tensile zog | 510-620 MPa |
| Elongation | Ntau dua lossis sib npaug li 21% |
| Impact Zog | Ntau tshaj lossis sib npaug rau 34 J ntawm 20 degree |
Muab piv rau cov khoom siv lub tog raj kheej ib txwm muaj (xws li HP295), HP345 nthuav tawm lub zog tawm los ntawm kwv yees li 15% -20%, muab lub hauv paus rau thinner- phab ntsa tsim.
Lub hauv paus ntsiab lus tseem ceeb ntawm "Ntau zog + Qhov hnyav txo"
Nce Yield Strength
Ib qho ntawm cov qauv tseem ceeb tshaj plaws hauv kev tsim lub tog raj kheej roj:
Siab-cov kabmob muaj peev xwm ∝ Cov Khoom Siv Lub Zog × Phab Ntsa Thickness
Thaum cov khoom siv zog nce ntxiv, phab ntsa tuab tuaj yeem txo qis thaum tuav qhov sib npaug siab-cov kabmob muaj peev xwm.
| Khoom siv | Yield zog (MPa) | Tsim phab ntsa Thickness (mm) | Hloov qhov hnyav |
|---|---|---|---|
| HP 295 | 295 | 6.0 | Lub hauv paus |
| HP 345 | 345 | 5.2 | ↓ Txog 13% |
Siv HP345 ua kom qhov hnyav ntawm kwv yees li 10-15%.
Tsawg Yield Ratio Tsim ntawm HP345 Hlau
HP345 gas cylinder steel yog tsim tshwj xeeb nrog cov qauv tsim tawm qis, uas yog qhov tseem ceeb ntawm kev nyab xeeb zoo rau kev siv lub nkoj siab.
Cov txiaj ntsig zoo ib yam ntawm HP345: ≈ 0.75 - 0.80Qhov kev ua kom zoo tshaj plaws no muab cov yas deformation zoo heev ua ntej ncav cuag lub zog tensile txwv, tso cai rau cov khoom kom ncab thiab deform ruaj khov es tsis txhob poob sai.
Qhov tseem ceeb ntawm kev nyab xeeb zoo
- Tiv thaiv kom txhob nkig nkig nyob rau hauv lub siab ntau dhau, HP345 deforms yas ua ntej es tsis txhob tawg los yog tawg yam tsis muaj ceeb toom, zoo heev txo qhov kev pheej hmoo tawg.
- Txhim kho tag nrho lub tog raj kheej tawg kev nyab xeebQhov kev ruaj khov deformation tus cwj pwm tsim kom muaj kev nyab xeeb dav dua, ua tau raws li cov qauv thoob ntiaj teb nruj heev rau LPG lub tog raj kheej thiab siab - cov thawv ntim roj.
- Txhim kho kev ntseeg siab nyob rau lub sijhawm ntev - kev pabcuam zoo dua rau kev qaug zog thiab kev hloov pauv siab ua kom muaj kev nyab xeeb dua rau kev siv txhua hnub thiab kev pabcuam ntev dua
Ua kom muaj zog + Qhov hnyav
Optimized Grain Structure
HP345 siv cov thev naus laus zis microalloying nrog cov kev sib ntxiv ntawm Nb (Niobium), V (Vanadium), thiab Ti (Titanium) kom ua tiav tag nrho cov nplej ua kom zoo.
Qhov no metallurgical tsim zoo heev txhim kho lub zog, toughness, qaug zog tiv thaiv, thiab tiv thaiv - cracking kev ua tau zoo - ua rau HP345 muaj kev nyab xeeb thiab txhim khu kev qha rau siab - siab gas cylinders.
| Qhov xwm txheej | nyhuv |
|---|---|
| Grain Refinement | Lub zog ↑ |
| Uniform Microstructure | Fatigue Resistance ↑ |
| Crack Propagation Resistance | ↑ |
HP345 yog engineered nrogmicroalloying cov ntsiab lussuav nrog Nb, V, thiab Ti kom ua kom zoo dua cov txheej txheem hauv cov nplej.Fine thiab niaj hnub nplej xa cov khoom siv kho kom zoo dua qub thaum tuav cov ductility siab.Cov qauv optimized txhim kho cov load-cov kabmob muaj peev xwm, ncua kev pabcuam lub neej, thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav thaum siv.
Yuav ua li cas Manufacturing txheej txheem ntxiv kom txo tau qhov hnyav nrog HP345 Steel
Tswj Rolling thiab Cooling
HP345 txais cov txheej txheem thermomechanical Controlled Processing (TMCP) kom tswj tau qhov kub thiab txias, deformation tus nqi, thiab txias ceev. Cov txheej txheem no optimizes nplej faib thiab txhim kho cov khoom ua tau zoo yam tsis muaj kev nce thickness lossis hnyav.
