Sehlahisoa sa Grey Cast Iron Casting ka Sand Casting

Grey cast iron ke tšepe e nang le ferrous eo cementite e bolang ho ba tšepe le k'habone ka sebopeho sa graphite e bitsoang graphitization cast irons moo karolo e kholo ea cementite e bolang ka graphitization.

Litšobotsi tsa Ts'ebetso ea Grey Aron Castings:
• Aine e bohlooho e na le mokelikeli o motle, 'me molumo oa eona o honyela le ho honyeha ha mela e nyane, le kutlo e nyane.
• Thepa e tlase e felletseng ea mochini, matla a ho hatella a ka bang 3 ~ 4 linako tse phahameng ho feta matla a thata
• Ho monya hantle ha tšepe, ho monya ha tšepe e bohlooho ka makhetlo a ka bang 10 ho feta tšepe e entsoeng ka tšepe.
• tšepe e bohlooho e na le modulus e tlaase ea elasticity

Litšobotsi tsa Sebopeho sa Grey Iron Castings:
• Botenya ba marako a manyenyane le libopeho tse rarahaneng li fumaneha
• Khatello e setseng ea ho lahla e nyenyane
• Litšepe tsa tšepe tse bohlooho ha lia lokela ho etsoa ka meaho e teteaneng haholo, 'me likarolo tsa asymmetrical hangata li sebelisoa ho sebelisa matla a tsona a hatellang ka botlalo.

Mokhoa oa ho lahla lehlabathee fana ka phetoho e kholo ka ho fetisisa le lisebelisoa tse bolokang chelete e ngata. Setsi sa rona sa ho lahla lehlabathe se na le laboratori e felletseng ea metallurgic ho fumana litšobotsi tsa lik'hemik'hale le tsa mochini tsa ho qhibiliha ka 'ngoe le ho sekaseka boemo ba metallugic ba tšepe e qhibilihisitsoeng pele e tšolloa. Li-microsections li hlahlojoa ka tlas'a microscope ho fumana tlhahisoleseding ea ho qetela mabapi le ho lahla ha solified. Re fana ka setifikeiti sa 3.1 bakeng sa karolo e 'ngoe le e 'ngoe e fanoeng ka kopo ea bareki. Lisebelisoa tsa tšepe ke li-alloys tsa ferrous tse nang le lik'habone tse fetang 2%. Le hoja litšepe tse entsoeng ka tšepe li ka ba le peresente ea carbon pakeng tsa 2 le 6.67, moeli o sebetsang hangata o pakeng tsa 2 le 4%. Tsena ke tsa bohlokoa haholo-holo ka lebaka la litšoaneleho tsa tsona tse babatsehang tsa ho lahlela. Litšepe tse bohlooho le li-ductile cast irons (tseo hape li bitsoang nodular cast iron kapa spheroidal graphite iron).

Melemo ea rona lebaleng la Sand Casting:
• Lilemo tse mashome tsa phihlelo ea ho etsa lehlabathe, ho lahla likhetla le theknoloji ea machining.
• Li-cores tse nepahetseng bakeng sa li-contours tse rarahaneng tsa ka hare.
• Therisano e pharaletseng e qalang mokhahlelong oa moralo.
• Tsamaiso ea boleng ho pholletsa le ts'ebetso ea tlhahiso le ts'episo e phahameng ea ts'ebetso.
