Zeziphi iimeko zenkqubo yokwenziwa kwendibano yevili elingasebenziyo?

I-Sand casting steel investment casting ibhekiselele ekwenzeni imodeli efusible ngezinto ezifusible, ukugquma amaleko aliqela eengubo ezinqabileyo ezikhethekileyo kuwo, ukomisa kunye nokuqina ukwenza iqokobhe elidibeneyo, kwaye emva koko usebenzisa umphunga okanye amanzi ashushu ukwenza isikhunta.Yinyibilikise imodeli eqokobheni, emva koko ubeke iqokobhe kwibhokisi yesanti, gcwalisa indawo ejikelezileyo ngokubumba isanti eyomileyo, faka isikhunta kwiziko lokutshisa lobushushu obuphezulu, kwaye ugalele isinyithi esinyibilikisiweyo kukubumba okanye iqokobhe emva kokuqhotsa. Kwaye ufumane castings.

Inkqubo kukufudumeza i-castings eyahlukeneyo kwiqondo lobushushu le-860-900 ℃, gcina i-matrix yoqobo yonke i-austenitized, emva koko ipholile kwi-oyile okanye ityuwa etyhidiweyo ukufezekisa ukucima, kwaye emva koko ubushushu, ubushushu, ubushushu kunye nomsindo kwi-250-350 ℃, kwaye i-matrix yokuqala iguqulwa ibe yi-Tempered martensite kwaye igcinwe i-austenite isakhiwo, i-original spherical shape yegraphite ihlala ingatshintshi.I-Ductile castings ifuna ubulukhuni obuphezulu njengeebheringi, kwaye idibano yevili engasebenziyo ihlala icinywa kwaye inomsindo kwiqondo lobushushu eliphantsi.

I-castings ephathwayo inobulukhuni obuphezulu kunye nokuqina okuthile, i-Liaoning cast iron igcina iimpawu zokuthambisa zegraphite, kwaye ukuxhathisa ukunxiba kuphuculwe ngakumbi.Iimveliso ezifunyenwe ngotyalo-mali zinzima, zisondele kwimilo yamacandelo, kwaye zinokusetyenziswa ngokuthe ngqo ngaphandle okanye ngokucutshungulwa okuncinci.Ayilungelanga kuphela ukujula kweentlobo ngeentlobo kunye nealloys, kodwa ikwavelisa ukujulwa ngokuchaneka okuphezulu kwedimensional kunye nomgangatho womphezulu kunezinye iindlela zokuphosa, kunye nokuntsonkotha, ukumelana nobushushu obuphezulu kwaye kunzima ukusetyenzwa kwesamente ekunzima ukuphoswa ngokunye ukuphosa. iindlela.Inokuphoswa ngokufakwa kotyalo-mali.
