Ngokwezibophelelo ezahlukeneyo zokwakha iqokobhe, utyalo-mali lunokwahlulwa lube yi-silica sol binder investment casting, igilasi yamanzi isibophelelo sotyalo-mali kunye nokuphosa utyalo-mali ngemixube yabo njengezinto zokubopha. I-silica sol iyisibophelelo esiqhelekileyo samanzi kunye nesakhiwo se-colloid ye-silicic. Sisisombululo se-polymer colloidal apho amasuntswana e-silica ahlakazeke kakhulu anyibilika emanzini. Iingqungquthela ze-colloidal zi-spherical kwaye zine-diameter ye-6-100 nm. Inkqubo yokuphosa utyalo-mali ukwenza igobolondo yinkqubo ye-gelling. Zininzi izinto eziphembelela i-gelation, ikakhulu i-electrolyte, i-pH, i-sol concentration kunye nobushushu. Kukho iintlobo ezininzi ze-silica sol zorhwebo, kwaye eyona isetyenziswayo yi-alkaline silica sol kunye nomxholo we-silica we-30%. Ukuze unqobe ukusilela komjikelezo omde wokwenza iqokobhe le-silica sol shell, i-silica sol eyomileyo ekhawulezayo iye yaphuhliswa kwiminyaka yakutshanje. Inkqubo yokwenza i-silica sol shell ilula. Inkqubo nganye ineenkqubo ezintathu: ukugquma, ukugalela isanti, nokomisa. Inkqubo nganye iphinda iphindwe kaninzi ukufumana igobolondo le-multilayer yobunzima obufunekayo.
Kwinkqubo yokwenza iqokobhe le-silica sol, ukomisa yeyona nkqubo ibaluleke kakhulu. Ngokumisa, amanzi aguquguqukayo, i-silica sol gels, kunye ne-particle refractory zidityaniswe ngokuqinileyo, ngaloo ndlela ifumana igobolondo eliphezulu. Olu lulungiselelo oluhle lokusalwa okulandelayo. Ukubunjwa okufunyenwe yinkqubo yokwenza iqokobhe le-silica sol kunoburhabaxa obusezantsi, ukuchaneka komgangatho ophezulu kunye nomjikelo wokwenza iqokobhe elide. Le nkqubo isetyenziswa ngokubanzi ekukhupheni i-alloys ekwazi ukumelana nobushushu obuphezulu, iintsimbi ezikwazi ukumelana nobushushu, iintsimbi ezingenasici, iintsimbi zekhabhoni, i-alloys ephantsi, i-alloys ye-aluminium kunye ne-alloys yobhedu.
I-silica sol echanekileyo elahlekileyo inkqubo yotyalo-mali yotyalo-mali ifanelekile kwimveliso ephindaphindwayo yezakhi zemilo yomnatha ukusuka kwiindidi ezahlukeneyo zesinyithi kunye ne-alloys yokusebenza ephezulu. Nangona ngokuqhelekileyo isetyenziselwa ukudubula okuncinci, le nkqubo isetyenziselwe ukuvelisa iifreyimu ezipheleleyo zeengcango zenqwelomoya, kunye neentsimbi zokujula ukuya kuma-500 kgs kunye nokuphoswa kwe-aluminiyam ukuya kuma-50 kgs. Xa kuthelekiswa nezinye iinkqubo zokuphosa ezifana ne-die casting okanye isanti casting, ingaba yinkqubo ebiza kakhulu. Nangona kunjalo, amacandelo anokuthi aveliswe kusetyenziswa utyalo-mali angabandakanya iikhontolo ezintsonkothileyo, kwaye kwiimeko ezininzi amacandelo afakwe kufutshane nemilo yenethi, ngoko ke afuna ukuphinda kusetyenzwe kancinane okanye angabikho emva kokuba esakhiwe.
Ngokwezinga le-carbon content, i-carbon steel for casting ihlulwe ngokubanzi ibe yintsimbi ephantsi ye-carbon, i-medium carbon steel kunye ne-carbon steel high. Iintsimbi zekhabhoni ezifakwe kuwo onke amazwe ehlabathi zihlelwa ngokubanzi ngokwamandla abo, kwaye amabakala ahambelanayo aqulunqwa.
Ngokuphathelele ukubunjwa kweekhemikhali zensimbi ye-carbon, ngaphandle kwe-phosphorus kunye ne-sulfure, akukho zithintelo okanye imida ephezulu kuphela kwezinye iikhemikhali. Ngaphantsi kwesiseko esingentla, ukubunjwa kweekhemikhali ze-carbon steel cast kunqunywe yi-Foundry ngokweempawu ezifunekayo zomatshini.
Iindlela zokunyanga ubushushu be-carbon steel castings zihlala zi-annealing, normalizing okanye normalizing + tempering. Kwezinye iintsimbi eziphezulu zekhabhoni, ukucima kunye nokutshisa kunokusetyenziswa, oko kukuthi, ukucima + ubushushu obuphezulu, ukuze kuphuculwe iipropati ezibanzi zoomatshini be-carbon steel castings. I-carbon steel castings encinci inokucinywa ngokuthe ngqo kwaye igxininiswe ukusuka kwimeko yokuphosa. Kwizinto ezinkulu okanye eziyinkimbinkimbi ze-carbon steel castings, kuyafaneleka ukwenza unyango lokucima kunye nokufudumala emva konyango oluqhelekileyo.
Kwintsimi yoshishino lwesinyithi kunye ne-metallurgical, isinyithi sithetha isinyithi kunye ne-alloys yazo equlethe isinyithi. Intsimbi yentsimbi ibandakanya intsimbi kunye nentsimbi yehagu kunye neziseko zidla ngokwahlulahlula zibe ziindidi ezimbini ezinkulu: intsimbi etyhidiweyo (intsimbi engwevu, intsimbi etyhidiweyo, intsimbi ekhatywayo ethambileyo, i-vermicular graphite cast iron etc.) intsimbi ye-alloy, insimbi engenasici njl. Ngenkqubo yokuphosa amagwebu elahlekileyo, i-RMC Casting Foundry inokugalela intsimbi engwevu, isinyithi se-ductile, intsimbi yealloyi kunye nentsimbi yekhabhoni.
