I-ASTM A319 iyinto empunga yensimbi yensimbi esetshenziswa ezingxenyeni ezingacindezeli zemithambo ezindaweni eziphakeme zokushisa. I-Standard yathuthukiswa yi-American Society ukuthola ukuhlolwa kanye nezinto zokwakha (ASTM), okokuqala ishicilelwe ngo-1971, futhi yaphinde yaphinde yaphinde yabunyelwa ngo-2001.
Ububanzi besicelo nezimpawu
I-ASTM A319 ejwayelekile isebenza kumabanga amathathu e-Iron Grey Cast, efanelekile kwizakhi zomkhumbi ezingacindezeli ezisebenza ezindaweni ezisezingeni eliphakeme, njengezakhi ze-grate, izingxenye zamabhokisi omlilo, isikhunta se-Ingot, isikhunta se-Ingot, kanye namabhodwe e-Ingot, kanye namabhodwe e-Ingot ancibiliki. Lezi zinsimbi ezi-cast zenza kahle ezindaweni zokushisa ezifika kumazinga okushisa afinyelela ku-1400℃f (760 degree), kepha lokhu akusho ukuthi wonke amabanga amathathu ensimbi empunga alungele lonke uhla lwensimbi empunga. Amanye amabanga alungele kuphela insizakalo yesikhathi eside emazingeni okushisa aphansi ngaphandle kokuthi ukucindezela kuphansi.
ukuwohloka kweklasi
I-Iron Grey Cast ihlukaniswe ngamabanga amathathu:
Ibanga I: ukumelana okuhle nokushaqeka kwe-thermal.
IBanga II: Isilinganiso sokuvikelwa kokushisa okusheshayo kanye ne-medium emandleni amahle ashubile (amandla ashubile avame ukuba ngaphezulu kwama-30,000 PSI noma i-207 MPA).
Ibanga III: Amandla aphezulu aphezulu aphezulu kunamaBanga I kanye ne-II (amandla ashubile angaba phezulu njenge-40,000 PSI noma i-276 MPA).
Inqubo Yokukhiqiza Nezidingo Zomzimba
I-ASTM A319 ejwayelekile ayicacisi inqubo yokushintshana, eshiywe ngokubona kwe-forry. Izinga lezinkomba namanye amazinga, njenge-ASTM A48, enemininingwane yokucaciswa kwensimbi empunga, kufaka phakathi ubunzima, amandla okuvuselela, amandla okuvutha, neminye imithwalo yezakhiwo zezindawo zokuhlola
