A516 GR70Puas yog ib tus neeg siv hlau siv feem ntau hauv cov boiler manufacturing, precisely engineered rau boiler kev ua haujlwm thaum ntsuas lub zog, kev nruj, thiab weldability. Piv rau lwm cov hlau, boiler - qib steel muaj cov txiaj ntsig hauv qab no:
1. Cov cim tseeb rau nruab nrab- rau - kub kub boiler tej yam
Cov Cheebtsam tseem xws li cov tub rog boiler thiab headers feem ntau ua haujlwm ntawm qhov kub thiab txias los ntawm -29℃rau 454 degree.
A516 Gr70 tus tsim qhov ntsuas kub siv tau meej txog cov kab ke no, xa cov kev cuam tshuam ruaj khov thiab muaj zog nyob hauv cov xwm txheej no.
Piv rau siab - kub cov hlau, A516 Gr70 yuav tsum tsis muaj ntxiv ntawm cov nqi alloy thiab zoo dua} {4 4}} qis kub.
Piv rau qhov tsis zoo li qub -} cov hlau carbon, A516 Gr70 muaj lub zog siab dua, txo cov nqi boiler ntau dua thiab raug nqi.
2. Sib xyaws nrog boiler raug cov txheej txheem
Boiler Fabrication cuam tshuam nrog cov kev siv vuam dav dav, qhov twg weld zoo cuam tshuam kev nyab xeeb ncaj qha.
A516 Gr70 cov ntsiab lus tsawg cov ntsiab lus (tsawg dua los yog sib npaug xws li manganese thiab silicing tej yam ntxim nyiam heev thaum vuam.
Nws yuav tsum tsis muaj cov preheating ua ntej vuam thiab tsis muaj qhov tseem ceeb tshaj tawm {}} Weld kev tsim khoom lag luam thiab cov hmoov txhuas ua kom luv.
Piv rau siab - Lub zog alloy qauv qauv hlau, A516 Gr70 yog qhov yooj yim rau kev loj hlob, ua kom loj rau loj {3} ntsuas ntau lawm.
3. Cov rog zoo heev thiab corrosion tsis kam
Boilers yauv rov qab pib dua {{0} Taug kev, thiab raug rau dej, chav, thiab lwm yam tshaj tawm, xav tau cov khoom siv ruaj khov.
A516 Gr70 ua rau cov khoom pov thawj zoo tshaj qub, nrog kev caij tsheb kauj vab siab tsis ua tiav. Nws muaj kev ntxhov siab corrosion tawm tsam hauv dej thiab chav ib puag ncig, txo cov kev pheej hmoo xau los ntawm kev tshaj tawm xov xwm.
Piv rau tus qauv siab lub nkoj siab tawv, A516 GR70 muaj lub neej zoo tshaj, txuas ntxiv lub neej kev ua haujlwm thiab lub rooj sib tham zoo dua boiler kev nyab xeeb.
4. Cov Qauv Sib Tham
A516 Gr70 yog ib qib me me hlau nyob hauv Astm cov qauv, dav thiab siv thoob ntiaj teb. Steel Mills ua haujlwm tsim cov txheej txheem ntau lawm, muab cov khoom siv thiab cov kav dej ruaj khov ntawm cov hlau uas muaj zog, ua kom muaj cov hlau loj me.
Piv rau tsis - tus qauv lossis niche steel menyuam, A516 Gr70 Cov nqi ib txwm muaj kev saib xyuas, thiab pab txhawb kev kho yooj yim dua tshiab thiab hloov kho yooj yim dua tshiab.
Ua haujlwm pab rau hauv cov lag luam hlau rau ntau tshaj 20 xyoo, los ntawm kev paub txog kev paub, tau xaiv cov khoom lag luam uas tsim nyog, tau xaiv cov khoom lag luam uas tsim nyog, thiab ntev} kev koom tes. Yog tias koj xav paub ntau ntxiv txog cov khoom lag luam steel lossis txaus siab rau kev yuav khoom lawv, thov xa email rauinfo@chinasteelcompany.comCov. Peb yuav tau rov qab rau koj sai li sai tau peb pom cov lus
