Kodi ASTM A516 Gr.70 yapangidwa ndi zinthu ziti?

ASTM A516 Gr.70 ndi zinthu za carbon steel. Mpweya wa carbon ndi gulu lazitsulo zomwe zimakhala ndi carbon monga chinthu chachikulu chothandizira, nthawi zambiri zimakhala ndi weldability wabwino choncho nthawi zambiri zimakhala zoyenera kupanga zitsulo.
ASTM A516 Gr.70 ili ndi mpweya wambiri wa carbon womwe umapangitsa kuti iziyenda bwino m'malo otentha komanso otentha. Nkhaniyi imagwiritsidwa ntchito popanga zitsulo zopondereza, ma boilers, makina otenthetsera kutentha ndi zinthu zina zomwe zimafunika kuti zithe kupirira kupanikizika kwakukulu ndi malo otentha kapena otsika.

ASTM A516 Gr.70 ndi ndondomeko yofotokozera katundu wakuthupi ndi zofunikira zamakina pazitsulo zazitsulo zotsika komanso kutentha kwambiri. Izi zidapangidwa ndi American Society for Testing and Materials (ASTM) ndipo zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, makamaka pankhani yamafuta, gasi, mankhwala, mphamvu yamagetsi, ndi mphamvu zanyukiliya.

Zofunika:

ASTM A516 Gr.70 ndi carbon zitsulo ndi weldability wabwino. Amagwiritsidwa ntchito kwambiri popanga zombo zothamanga kwambiri komanso zotsika kutentha zosungiramo mpweya kapena zakumwa.

Makhalidwe amakanika:

Zofunikira zamakina zamakina zimaphatikizira kulimba kwamphamvu, mphamvu zokolola, komanso kutalika, pakati pa ena. ASTM A516 Gr.70 nthawi zambiri imakhala ndi mphamvu zochulukirapo komanso zokolola, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito kuthamanga kwambiri.

Kutentha:

Ikhoza kugwira ntchito m'malo otsika komanso otentha kwambiri, choncho ndi oyenera kugwiritsa ntchito zosiyanasiyana ndi zofunikira zosiyanasiyana za kutentha.

Zokhazikika:

Kupanga ndi kuyesa kwa ASTM A516 Gr.70 kumatsatira mulingo wa ASTM A516/A516M, womwe umafotokozera kapangidwe kazinthu, njira zoyesera zamakina, komanso zofunikira pakulimba, kuyesa kwamphamvu, ndi zina zambiri.

Minda yofunsira:

ASTM A516 Gr.70 imagwiritsidwa ntchito popanga zigawo za boilers, zotengera zokakamiza, zosinthira kutentha, mapaipi, ndi machitidwe ena apamwamba kwambiri. Ntchitozi zimafuna zipangizo zomwe zingathe kupirira kupanikizika kwakukulu ndi malo otentha kwambiri pamene zikusunga kudalirika ndi chitetezo cha zinthuzo.

Mwachidule, ASTM A516 Gr.70 ndi zinthu zomwe zimagwiritsidwa ntchito pokakamiza chotengera zinthu zomwe zimakhala ndi makina abwino komanso kutentha kwambiri komanso kukana kutentha kwapansi, ndipo ndizoyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana. Mukagwiritsidwa ntchito, miyezo yoyenera yopangira ndi kukhazikitsa iyenera kutsatiridwa kuti zitsimikizire kuti chitetezo ndi magwiridwe antchito a zombo zopanikizika zimakwaniritsa zofunikira.
