Kutentha zinyalala Ng'anjo kabati Chitofu kabati
Makina osakanikirana ndi kutentha nthawi zambiri amapangidwa ndi ma steel osapanga dzimbiri omwe ali ndi kuchuluka kwa Chromium ndi Nickel. Zotayidwa zopangidwa ndi zotengera zosagwiritsa ntchito kutentha ndizabwino kwambiri pazinthu zomwe zimawonetsedwa ndi mpweya wouma kutentha kwambiri kwakanthawi. Makampani omwe amapindula ndi kutentha kosaponyedwa ndi monga Energy, Engines, Furnaces / Ovens, ndi Petrochemical.
Kutentha castings zitsulo amatchedwanso castings makutidwe ndi okosijeni zosagwira, castings refractory zitsulo, kutentha zosagwira castings zosapanga dzimbiri.
Kutentha zosagwira ndi mtundu wa aloyi zitsulo kuti ali apamwamba mawotchi mphamvu ndi bwino mankhwala bata pa kutentha.
Kutentha zosagwira castings akhala akugwiritsidwa ntchito kupanga kutentha zosagwira m'ng'anjo mafakitale, kutentha exchanger, matenthedwe mankhwala ng'anjo, kabati ozizira ndi zipangizo zina kutentha zosagwira mafakitale.
Mulingo wa ASTM A297 umakwirira chitsulo-chromium ndi chitsulo-chromium-faifi tambala aloyi castings ntchito kutentha zosagwira, sukulu anaphimba ndi ASTM A297 ndi zolinga alloys ambiri ndipo palibe anayesa anaphatikizapo kutentha-kukana kasakaniza wazitsulo ntchito yapadera ntchito ntchito.
XTJ monyadira kupereka kutentha zosagwira castings zitsulo kuti bwinobwino akwaniritse ASTM A297 muyezo, kuphatikizapo:
• ASTM A297 Kalasi HF, Mtundu 19Cr-9Ni
• ASTM A297 Kalasi HH, Mtundu 25Cr-12Ni
