Q345b Steel Phaj

Kev nce qib txuas ntxiv ntawm Q345b steel phaj thev naus laus zis hauv smelting thiab kho cua sov, thiab kev txhim kho thiab tsim cov forged (cam khwb cia) steel phaj los ntawm dov tau ua tiav cov txiaj ntsig zoo. Lub thickness ntawm cov hlau phaj uas tuaj yeem hloov forging (casting) qhov chaw tau mus txog 410mm, thiab qhov siab tshaj plaws qhov hnyav yog 38 tons. Ua tus thawj coj hauv kev hloov pauv thiab ua kom cov khoom siv loj ingot ntau lawm hauv Suav teb, sau qhov sib txawv ntawm cov khoom siv high-end nyob rau hauv lub teb chaws thoob plaws thiab hnyav phaj teb thiab hloov imports. Loj-thickness Z35-qib steel phaj, ua kom zoo dua ntawm cov cuab yeej siv thiab cov khoom siv, yog qhov loj-thickness Z-kev taw qhia steel phaj nrog lub thickness ntawm 200mm-300mm. Qhov loj-thickness Z35 steel phaj yog ib hom ntawm cov hlau tuab ntxiv siv nyob rau hauv ib puag ncig tej yam kev mob, xws li lub turbine lub nplhaib, qhia vane thiab lwm yam tseem ceeb ntawm lub tshuab hluav taws xob teeb, thiab nws txoj kev nyab xeeb, kev cia siab thiab kev pab lub neej ntev. siab heev. Txhawm rau txhim kho 200mm-300mm tuab steel phaj nrog lub thickness loj ntawm Z35 qib, nws yog ib qho tsim nyog los xyuas kom meej tias qhov kev ua tau zoo ntawm cov lamellar tearing mus txog qib Z35. Qhov no yog qhov nyuaj heev "Olympic kev sib tw lo lus nug" lees paub los ntawm kev lag luam metallurgical. Nws yog ib qho tsim nyog yuav tsum tau kov yeej cov teeb meem xws li kev tswj hwm ntawm cov hlau loj loj, kev kho cua sov ntawm cov phaj loj loj, qhov kub tsis tshua muaj kev cuam tshuam toughness ntawm loj thickness steel daim hlau thiab laminar tsim kua muag kuj. Lub hauv paus ntsiab lus: Ib qho yog los xyuas kom meej tias nws muaj weldability zoo; lwm yam yog los xyuas kom meej qhov kev ua tau zoo nyob rau hauv lub thickness kev taw qhia; qhov thib peb yog los xyuas kom meej tias nws muaj kev cuam tshuam txaus toughness reserves thiab tsis tshua muaj ductile brittle hloov kub ntawm kev siv kub; qhov thib plaub yog los txhim kho kev ruaj ntseg ntawm cov qauv. Siv cov khoom siv tes ua haujlwm zoo los tsim cov khoom zoo Z-kev taw qhia steel nrog loj tuab rau hydropower. Rau tag nrho cov txheej txheem txuas xws li smelting, dov, kev kho cua sov, tag nrho cov txheej txheem yog taug qab, thiab cov hluav taws kub kub ntawm 500 degrees Celsius raug zam, thiab 200mm tuab S355J0-Z35 thiab 270mm tuab A516Gr70-Z35 steel daim hlau tau tsim ua tiav. Raws li EN10025 qauv thiab hydropower tsim Raws li cov kev cai ntawm lub koom haum, lub Z35 steel phaj nrog lub thickness ntawm 300mm yog thaum kawg ua tiav. Tom qab kev soj ntsuam, nws tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm cov qauv kev tsim nyog thiab ncav cuag qhov tseeb. Nws txoj kev vam meej tau nce qib kev loj hlob ntawm kuv lub teb chaws hydropower loj-thickness Z-steel technology. Kev tshawb fawb thiab kev loj hlob ntawm 300mm tuab Z35 steel phaj tau hloov qhov xwm txheej uas kuv lub teb chaws hydropower kev lag luam tau ntev cia siab rau imports ntawm loj-thickness Z-kev taw qhia steel, uas yog ib qho tseem ceeb rau lub localization ntawm loj-scale khoom. Lub 300mm-thick Z35 steel phaj yog ib qho tshiab rau qhov loj-thickness Z-kev taw qhia hlau nkag mus rau hauv kev lag luam hydropower. Qhov no yuav inevitably txhawb kev txuas mus ntxiv hauv kev txhim kho loj-thickness Z-kev taw qhia steel rau hydropower. Qhov tseem ceeb tshaj plaws, 300mm tuab Z35 steel phaj tuaj yeem siv tsis yog hauv kev lag luam hydropower nkaus xwb, tab sis kuj tseem nyob rau hauv kev tsim khoom ntawm lwm cov khoom siv loj loj, uas muaj kev cia siab dav.
