Custom Grey Cast Iron Sand Casting

Xa siphosa intsimbi engwevu, silandela ngokungqongqo ukubunjwa kweekhemikhali kunye neempawu zoomatshini ngokweestardards okanye iimfuno ezivela kubathengi. Ngaphandle koko, sinakho ukukwazi kunye nezixhobo zokuvavanya ukuba kukho iziphene zokuphosa ngaphakathiukugalelwa kwesanti yentsimbi engwevu.

Iialloyi zeferrous ezinekhabhoni engaphezulu kwe-2% zibizwa ngokuba ziintsimbi ezityhidiweyo. Nangona iintsimbi eziphothiweyo zinokuba nepesenti yekhabhoni phakathi kwe-2 ukuya kwi-6.67, umda osebenzayo uqhelekile phakathi kwe-2 kunye ne-4%. Ezi zibalulekile ikakhulu ngenxa yeempawu zabo ezibalaseleyo zokusa.

Iintsimbi ezingwevu zitshiphu kunei-ductile iron castings, kodwa inamandla asezantsi kakhulu kunye ne-ductility kune-ductile iron. Intsimbi engwevu ayinakuthatha indawo yentsimbi yekhabhoni, ngelixa intsimbi yentsimbi inokuthi ithathe indawo yentsimbi yekhabhoni kwimeko ethile ngenxa yokuqina okuphezulu, amandla esivuno kunye nokwandiswa kwesinyithi.

Ukusuka kumzobo we-iron-carbon equilibrium diagram, kunokubonwa ukuba iintsimbi ezenziwe ngentsimbi zine-cementite kunye ne-ferrite. Ngenxa yepesenti enkulu yekhabhoni, inani le-cementite liphezulu likhokelela kubulukhuni obuphezulu kakhulu kunye neempawu zokuqina kwentsimbi.
