7. Cov Lus Qhia Tseem Ceeb
Tus qauv TU no nruj dua li GOST thiab tsim tshwj xeeb rau kev siv boiler supercritical thiab ultra-supercritical.
Peb qib tiv taus cua sov tseem ceeb yog 12Kh1MF (570-585 C), 15Kh1M1F (<=585 C), thiab 12Kh2MFSR (<=620 C).
10Kh9MFB-Sh yog kwv yees li sib npaug rau P91, tab sis cov ntsiab lus ntawm cov khoom sib xyaw thiab kev tshuaj xyuas txawv; xyuas kom meej ua ntej hloov pauv.
Yuav tsum tau kuaj 100% los ntawm kev siv tshuab ultrasound, siv cov qauv piv txwv (SOP) rau kev ntsuam xyuas qhov tsis zoo.
Ntawm cov qib austenitic, 12Kh18N12T muaj qhov kub thiab txias siab tshaj plaws (txog li 800 C rau kev pabcuam yeeb nkab luv luv).
