Kuphimba Flux Kwa Aluminium Alloy Casting
Makhalidwe:
White ufa, tinthu kukula <20 mauna, madzi zili pansi 0.5%.
Malangizo:
Aluminiyamu ndi zitsulo zotayidwa ndi aluminiyamu zina osati ma magnesium alloys.
Mlingo wolozera:
Werengetsani ndi kuyeza molingana ndi dera la0.5-1.0kg/m²aluminiyamu wosungunuka, werengerani ndi kulemera molingana ndi kulemera kwa0.2%-0.4%aluminiyamu wosungunuka.Ndipo malingana ndi chiyero cha kusungunuka ndi chinyezi mumlengalenga, kaya kuwonjezeka kapena kuchepa.
Malangizo:
Thealuminium alloy fluxkuphimba flux amagwiritsidwa ntchitokuteteza aluminium oxidation,kwamkating'anjochophimba,kuchepa kwa okosijenindikuyaka kutaya.
Pamene zinthu zodetsedwa ndi zosakanikirana zopanda zitsulo zimatsukidwa ndi wothandizira wophimba, mawonekedwe a slag pamtunda ndi phala kapena madzi, malingana ndi kuchuluka kwa wothandizira wowonjezera.
Kuti madzi amadzimadzi aphimbe kwathunthu, m'pofunika kuwonjezera zowonjezera zowonjezera kangapo.Ndi bwino kuwonjezera pamene chitsulo chimayamba kusungunuka.Chitsulo chikasungunuka kwathunthu ndikuyima, chophimba chiyenera kugwiritsidwa ntchito kuti chiteteze kusungunuka.
Ubwino waukulu:
1. Ikhozakupanga wosanjikiza wandiweyani chitetezondikuchepetsa kulowa kwa gasi.
2 Chepetsani kuwonongeka kwachitsulochifukwa cha makutidwe ndi okosijeni wa madzi pamwamba.
3 Lili ndi ubwino waPakatikati yosungunuka, fluidity yabwinondiKuphunzira bwino.
4 Thekumwa kumakhala kochepa, ndimtengo ndi wotsika, ndipo zitsulo zomwe zili mu slag zopangidwa ndizochepa kwambiri.
Kupaka ndi kusunga:
Bokosi lamalata/chikwama cholukidwa:2.5-10kg pa thumba lamkati, 20-50kg pa bokosi.Kusungirako koyenera, tcherani khutu ku chinyezi.
