ST35.8 yog German boiler thiab siab nkoj steel yeeb nkab khoom uas ua raws li tus qauv DIN 17175.
Tshuaj muaj pes tsawg leeg:Cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.17%, manganese cov ntsiab lus 0.40-1.20%
Mechanical Properties:Tensile lub zog 360-480 MPa, lav qhov kub thiab txias yield zog
Cov Lus Qhia Tshwj Xeeb:Yuav tsum tau kuaj xyuas hydrostatic thiab kuaj ultrasonic.
ST35.8 seamless steel yeeb nkab yog tsim los ntawm ob txoj kev: kub dov thiab txias kos duab.
Kub Rolling txheej txheem: Lub billet yog rhuab mus rau ib ncig ntawm 1200℃rau tho thiab dov. Txoj kev no muaj kev ua tau zoo ntau lawm, ua rau nws tsim nyog rau loj -scale manufacturing.
Txias Drawing txheej txheem: Cov yeeb nkab steel yog kos los ntawm kev tuag ntawm chav tsev kub. Txoj kev no ua rau cov kav dej nrog qhov tseeb dua qhov tseeb thiab zoo dua qhov chaw tiav, txawm tias ntawm tus nqi ntau dua.
Tsis hais txog ntawm cov txheej txheem, kev tshuaj xyuas online nruj thiab kev tswj xyuas zoo yog qhov yuav tsum tau ua, suav nrog kev kuaj ultrasonic, eddy tam sim no kuaj, thiab kuaj hydrostatic, kom ntseeg tau tias txhua cov yeeb nkab ua tau raws li cov qauv xav tau.
GNEE Group muaj peev xwm ua tau ST35.8 seamless steel kav nyob rau hauv ntau qhov ntau thiab tsawg, xws li 6mm mus rau 1200mm inch, catering rau ntau yam kev xav tau kev lag luam.
ST35.8 seamless steel yeeb nkab, nrog rau nws qhov siab - kub thiab siab - siab tsis kam, feem ntau yog siv rau hauv cov xwm txheej hauv qab no:
Boiler Manufacturing Kev Lag Luam: Rau kev tsim cov khoom tseem ceeb xws li superheater raj, reheater raj, thiab cov kav dej qhia cov kav dej hauv ntau chav boilers.
Petrochemical Field: Rau kev xa khoom siab - kub thiab siab - cov roj thiab cov pa tawm.
Kev lag luam fais fab: Rau cov cua sov saum npoo piping systems hauv fais fab nroj tsuag boilers. Tsis tas li ntawd, nws pom kev siv dav hauv kev tsim khoom siv tshuab, kev lag luam tsheb, thiab lwm yam. Tshwj xeeb hauv kev tsim kho ntawm ultra-supercritical chav boilers, ST35.8 seamless steel yeeb nkab tau dhau los ua cov khoom siv tsis tau vim nws muaj peev xwm tswj tau qhov ua tau zoo txawm tias nyob ntawm 570 degree.
