Kuyini ukuzinza okushisayo kombhede we-cast iron in machining? Uma kuqhathaniswa nombhede wokuphonsa amaminerali, iyiphi impahla engagcina ukuzinza kokunemba komshini?

Ukuzinza Okushisayo Kwemibhede Yensimbi Yensimbi Emachining: Ukuqhathaniswa Nemibhede Yomshini Wokuphonsa Amaminerali

Emkhakheni wokwenza imishini enembayo, ukuzinza kombhede womshini kubaluleke kakhulu ekugcineni ukunemba nokuqinisekisa ukuphuma kwekhwalithi ephezulu. Izinto ezimbili ezivame ukusetshenziswa emibhedeni yomshini insimbi ekhonjiwe kanye ne-mineral casting (eyaziwa nangokuthi ukhonkolo we-polymer). Impahla ngayinye inezici zayo eziyingqayizivele ezithinta ukuzinza kokushisa futhi, ngenxa yalokho, ukunemba kwemishini.

Ukuzinza Okushisayo Kwemibhede Yensimbi Yensimbi

I-cast iron ibilokhu iyisisekelo embonini yokukhiqiza amashumi eminyaka, ikakhulukazi ngenxa yezakhiwo zayo ezinhle kakhulu zokudambisa kanye nokuqina. Kodwa-ke, uma kuziwa ekuzinzeni kokushisa, insimbi yensimbi inemikhawulo yayo. Imibhede ye-cast iron inganwebeka futhi isebenze ngokushintshashintsha kwezinga lokushisa, okungaholela ekushintsheni kobukhulu futhi kuthinte ukunemba komshini. I-thermal conductivity ye-cast iron iphakeme kakhulu, okusho ukuthi ingakwazi ukumunca ngokushesha futhi ikuqede ukushisa, kodwa lokhu kuphinde kusho ukuthi ingase ibe lula ekuhlanekezeleni okushisayo.

Imibhede Yomshini Wokuphonsa Amaminerali

Ngakolunye uhlangothi, imibhede yomshini wokuphonsa amaminerali ithola ukuthandwa ngenxa yokuqina kwayo okushisayo okuphakeme. I-mineral casting iyinhlanganisela eyenziwe ngengxube ye-epoxy resin kanye nama-mineral aggregates njenge-granite. Le nhlanganisela iphumela kokuthile okune-conductivity ephansi ye-thermal kanye ne-thermal inertia ephezulu, okusho ukuthi mancane amathuba okuba ube nezinguquko ezisheshayo zokushisa. Ngakho-ke, imibhede yokuphonsa amaminerali ingagcina ukuqina kwayo kobukhulu kangcono kunemibhede yensimbi esakazwa ngaphansi kwezimo ezishisayo ezihlukene.

Ukuhlaziya Ngokuqhathanisa

Uma uqhathanisa lezi zinto ezimbili, imibhede yomshini wokuphonsa amaminerali ngokuvamile inikeza ukuzinza okungcono okushisayo kunemibhede yensimbi ekhonjiwe. I-thermal conductivity ephansi ye-mineral casting isho ukuthi ayithinteki kancane ekushintsheni kwezinga lokushisa elizungezile kanye nokushisa okukhiqizwa phakathi nezinqubo zomshini. Lokhu kuzinza kuhumusha ukunemba komshini okungaguquki, okwenza ukusakaza kwamaminerali kube inketho ekhangayo yezinhlelo zokusebenza ezinemba okuphezulu.

Sengiphetha, ngenkathi i-cast iron ihlala iyinto ethembekile futhi esetshenziswa kabanzi emibhedeni yomshini, ukukhishwa kwamaminerali kunikeza ukuzinza okushisayo okuphakeme, okungathuthukisa kakhulu ukunemba kwemishini. Njengoba isidingo sokunemba ekukhiqizeni siqhubeka sikhula, ukukhethwa kwezinto zombhede womshini kuzodlala indima ebalulekile ekuzuzeni nasekugcineni amazinga aphezulu.
