Ƙirƙirar Finhole A cikin Simintin Aluminum

Hydrogen shine babban abin da ke haifar da pinholes (80-90 na iskar gas da aka narkar da a cikin ruwa na aluminum shine hydrogen), kuma hydrogen yana samuwa ne ta hanyar bazuwar tururin ruwa. 

Dalilin samar da tururin ruwa a lokacin aikin narkewar aluminum gami shine babban abin da ke tasiri kai tsaye ga samuwar pinholes. Babban abubuwan da ke shafar samuwar pinholes sune:

A lokacin da aluminum gami smelting da zub da tsari, da albarkatun kasa, karin kayan, crystal ruwa a wasu kayan, da aluminum tsatsa AL (OH) 2 sun bazu don samar da danshi. 

Akwai kayan taimako da yawa na kwayoyin halitta da inorganic a cikin kayan ƙirar. Danshi da ke ƙunshe a cikin simintin gyare-gyare irin su kayan taimako da sutura saboda rashin zafin jiki mara kyau zai haifar da babban adadin iskar gas saboda bazuwar tururin ruwa a lokacin narkewar aluminum gami da zubewa. Lokacin da kayan narkewa daban-daban suka narke aluminum mutu Fitars, adadin iskar da ake samu na aluminum gami da matakin samuwar pores sun bambanta. 

Sabbin kututtukan da tsoffi da tsatsa da datti sai a hura yashi ko kuma a cire su ta wasu hanyoyin kafin a yi amfani da su, sannan a dumama su zuwa 700 ℃ -800 ℃ don cire ruwan da sauran sinadarai da crucible ke sha. Ana samun tururin ruwa yayin narkewa da zubowa don samar da pores.

Don kayan aikin narkewa, irin su ladle, murfin kararrawa, da dai sauransu, ya kamata a cire ƙarfe na sama, sikelin oxide da sauran datti kafin amfani; kayan aikin aluminum-magnesium gami ya kamata a sanya su akan carnallite kafin amfani da Wanke cikin juzu'i.

Idan preheating ba shi da kyau, danshin da ke sha a saman zai haifar da yawan iskar gas saboda dumama don samar da tururin ruwa a lokacin narkewa da zubar da ruwa, yana haifar da samuwar pinholes a cikin simintin aluminum.
