| Nyhav-Txuag muaj peev xwm | Qhov tseem ceeb vs. steel me me (~ 50-60% qhov hnyav txo) | Qhov siab tshaj plaws - tso cai ntxiv ~ 20-30% qhov hnyav txo vs. S690Q |
| Nqi | Siab, tab sis kuj muaj ntau dua | High-premium pricing vim complex alloying thiab ua |
| Tej kev siv | Cranes, cov khoom siv mining, cov qauv sab nrauv, kev thauj mus los hnyav | Qhov hnyav heev- cov khoom tseem ceeb: ultra- siab- lub peev xwm crane booms, cov tsheb tub rog siab heev, siab -kev ua tau zoo sib tw thav ntawv, qhov tseem ceeb ntawm kev khawb av / tho qhov |
Key Engineering Trade-offs:
Strength vs. Toughness & Ductility
S960Q muab lub zog ntau dua tab sis nrog txo qis toughness thiab ductility. Qhov no ua rau nws yooj yim dua rau kev ntxhov siab, qaug zog, thiab pob txha tawg. Kev tsim qauv siv S960Q yuav tsum tau ua tib zoo saib xyuas kom meej (piv txwv li, kev hloov pauv, txo qis).
Fabrication Complexity
Vuam thiab machining S960Q yog qhov xav tau ntau dua. Vuam feem ntau xav tau:
Siab dua preheat / interpass kub (txog 250℃rau tuab seem).
Kev siv nruj ntawm cov khoom siv tsis zoo (piv txwv li, 890 MPa yield) los txhim kho cov vuam hlau toughness.
Yuav tsum tau tshaj tawm -weld heat treatment (PWHT) feem ntau los kho HAZ toughness thiab txo kev ntxhov siab.
Tsim Philosophy
S690Q yog ntau yam, siab - lub zog xaiv rau ntau yam ntawm cov ntawv siv hnyav -.
S960Q yog cov khoom siv niche tsuas yog siv qhov twg txhua kilogram khaws tseg yog qhov tseem ceeb (piv txwv li, crane booms qhov twg ntxiv qhov ntev / muaj peev xwm tau txais, lossis cov tsheb tub rog qhov hnyav tsav tsheb).
Economic & Muaj
S960Q yog kim dua (feem ntau 2-3 × tus nqi ntawm S690Q) thiab ua rau me me. Nws yog feem ntau tshwj tseg rau cov khoom tshwj xeeb, kev ntxhov siab heev, tsis yog tag nrho cov qauv.
Thaum xaiv qhov twg:
Xaiv S690Q rau feem ntau siab - daim ntawv thov lub zog xav tau qhov sib npaug ntawm lub zog, toughness, weldability, thiab tus nqi- ua tau zoo.
Xaiv S960Q tsuas yog thaum lub zog siab tshaj plaws - rau- qhov hnyav piv yog qhov tseem ceeb tshaj plaws, thiab pab pawg neeg tsim khoom tuaj yeem tswj hwm nws cov kev sib tw tsim khoom, kev tswj xyuas kom zoo, thiab cov nqi siab dua.
Nyob rau hauv luv luv, S960Q thawb cov kev txwv ntawm lub zog thiab lub teeb yuag tsim tshaj S690Q tab sis ntawm tus nqi ntawm kev txo qis tsis kam, ntau nruj fabrication txoj cai, thiab cov nqi siab dua.
