Txheej txheem yam ntxwv ntawm SPV490
Refined Thermomechanical Kev Kho Mob
Txais kev tswj dov thiab normalized / quenched - tempered thermal ua, precisely tswj cov cua kub kub (880-950 degree) thiab txias npaum li cas. Qhov no refines lub grain qauv, uniformly faib txhua yam khoom thoob plaws lub phaj, thiab xyuas kom meej lub zog siab thiab qis - kub toughness coexist yam tsis muaj kev sib haum xeeb.
Weldability zoo heev
Cov pa roj carbon tsawg thiab tswj cov ntsiab lus alloy cov ntsiab lus txo cov hardenability ntawm weld cheeb tsam. Tsis muaj preheating los yog tsawg preheating (tsawg dua los yog sib npaug li 100 degree) yog yuav tsum tau rau cov pa vuam txheej txheem (MIG / TIG / submerged arc vuam). Lub weld sib koom ua ke nrog lub hauv paus hlau nyob rau hauv lub zog thiab toughness, tsis txhob txias tawg thiab ua kom cov vuam zoo thiab cov qauv kev ncaj ncees.
Strict Dimensional & Surface Control
Nruab nrog siab -precision dov thiab leveling cov cuab yeej, lub phaj ua tiav qhov ntev ntev (thickness kam rau ua ± 0.5mm, flatness Tsawg dua lossis sib npaug li 2mm / m). Kev kho deg nruj tshem tawm oxide nplai thiab qhov tsis xws luag, nrog rau qhov zoo ntawm lub rooj sib tham JIS G3115 Class A cov qauv, tsim nyog rau kev ua haujlwm ncaj qha thiab sib dhos.
Stable Batch Consistency
Ua kom tiav - txheej txheem kev soj ntsuam zoo los ntawm smelting mus rau cov khoom tiav, nrog rau qhov tseeb - sij hawm soj ntsuam cov tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab. Txhua batch ntawm steel daim hlau hla kev ua tau zoo pov thawj, kom ntseeg tau tias tsis muaj kev hloov pauv ntawm cov cuab yeej cuab tam, uas ua tau raws li qhov yuav tsum tau ua ntawm kev tsim cov hlab ntsha siab.
qhov zoo
Siab zog & hnyav txo: Raws li qib siab tshaj plaws hauv tus qauv (Yield Ntau dua lossis sib npaug rau 490MPa), nws tso cai rauphab ntsa nyias, txo tag nrho cov qauv hnyav thiab cov nqi khoom siv.
Weldability zoo heev: Optimized low carbon equivalent (Ceq) suppresses txias cracking, xyuas kom meejsiab sib koom siabrau siab- cov hlab ntsha nruj.
Tsawg-Tsub Toughness: Ua kom muaj kev cuam tshuam siab ntawm-10℃lossis qis dua, tiv thaiv brittle fracture nyob rau hauv siab heev los yog huab cua txias.
Thermal & Pressure stability: Tshwj xeeb engineered los tiv thaiv cov sustainedthermal stress thiab siab sab hauvmuaj nyob rau hauv refineries thiab fais fab nroj tsuag.
Ntiaj teb no Standard Compatibility: Feem ntau siv los ua kev ua haujlwm siab - lwm txoj rauASTM A537 Qib 2, ua rau nws zoo tagnrho rau thoob ntiaj teb boiler thiab tank tej yaam num.
