Intsimbi yesiko engwevuiqokobhe lokubunjwa ngundongeenkonzo zeunyango lobushushukunye nonyango olungaphezulu.

Ukubunjwa kweqokobheInkqubo ikwabizwa ngokuba yinkqubo yokugalela yentlabathi eqatywe ngaphambili, ukubunjwa kweqokobhe elishushu okanye inkqubo yokugalela engundoqo. Izinto eziphambili zokubumba yintlabathi ye-phenolic resin efakwe ngaphambili, ebiza kakhulu kunesanti eluhlaza kunye nesanti ye-furan resin. Ngaphezu koko, le santi ayinakuphinda isetyenziswe.

I-Furan resin self-ukuqina kwesanti inkqubo yokugalela (inkqubo ye-nobake) isebenzisa i-furan resin egqunywe isanti ukwenza i-mold yokuphosa. Emva kokuxuba isanti yoqobo (okanye isanti ebuyisiweyo), intlaka ye-furan elulwelo kunye ne-catalyst engamanzi ngokulinganayo, kwaye uyigcwalise kwibhokisi engundoqo (okanye kwibhokisi yesanti), kwaye emva koko uyiqinise ukuze iqine ibe ngumbumba okanye i-mold kwibhokisi engundoqo (okanye isanti. ibhokisi) kwiqondo lokushisa. Emva koko i-mold casting okanye i-casting core yaqulunqwa, ebizwa ngokuba yi-self-hardening ebandayo-ibhokisi yokubumba (i-core), okanye indlela yokuziqinisa (core).

Ngenxa yokuba umngundo wenziwe kwiqondo lobushushu begumbi kwaye akukho mfuneko yokufudumeza, ukuziqinisa kwesanti kukwabizwa ngokuba yinkqubo yokuphosa yokubhaka. Indlela yokuziqinisa inokwahlulwa ibe yi-acid-catalyzed furan resin kunye ne-phenolic resin sand self-harding method, i-urethane resin sand self-harding method kunye ne-phenolic monoester self-harding method.

Njengesanti ebopha ibhokisi ebandayo ezenza lukhuni, isanti ye-furan resin yeyona ntlabathi yokuqala kwaye ngoku isetyenziswa kakhulu kwisiseko saseTshayina. Isixa se-resin esongeziweyo kwisanti yokubumba ngokuqhelekileyo yi-0.7% ukuya kwi-1.0%, kwaye isixa se-resin eyongezelelweyo kwisanti engundoqo ngokubanzi yi-0.9% ukuya kwi-1.1%. Umxholo we-aldehyde yasimahla kwi-furan resin ungaphantsi kwe-0.3%, kwaye ezinye iifektri ziye zehla ukuya ngaphantsi kwe-0.1%. Kwiziseko zase-China, isanti ye-furan ye-resin yokuziqinisa ifikelele kwinqanaba lamazwe ngamazwe kungakhathaliseki ukuba yinkqubo yokuvelisa kunye nomgangatho womphezulu we-castings.

Intsimbi engwevu, okanye intsimbi engwevu, luhlobo lwentsimbi etyhidiweyo ene-graphite microstructure. Ithiywe ngombala ongwevu wokuqhekeka owenzayo. Intsimbi yentsimbi engwevu isetyenziselwa izindlu apho ukuqina kwecandelo kubaluleke kakhulu kunamandla okuqina, njengeebhloko ze-cylinder injini yokutsha yangaphakathi, izindlu zempompo, imizimba yevalvu, iibhokisi zombane, iintsimbi zokubala kunye neentsimbi zokuhombisa. I-iron ekhutshiweyo ephezulu ye-thermal conductivity kunye nomthamo okhethekileyo wentloko zihlala zisetyenziselwa ukwenza i-cookware yentsimbi kunye ne-disc brake rotors.

Ukubunjwa kweekhemikhali eziqhelekileyo ukufumana i-microstructure ye-graphic yi-2.5 ukuya kwi-4.0% yekhabhoni kunye ne-1 ukuya kwi-3% ye-silicon ngesisindo. Igraphite inokuthatha i-6 ukuya kwi-10% yomthamo wentsimbi engwevu. I-silicon ibalulekile ukwenza isinyithi esimpunga ngokuchasene nentsimbi emhlophe, kuba i-silicon yinto yokuzinzisa i-graphite kwi-iron cast, oku kuthetha ukuba inceda i-alloy ivelise i-graphite endaweni ye-carbides yensimbi; kwi-3% ye-silicon phantse akukho khabhoni ebanjwe kwimichiza edibeneyo kunye nentsimbi.

Igraphite ithatha imilo yeflake ene-dimensional ezintathu. Kwimilinganiselo emibini, njengoko ubuso obukhazimlisiweyo buza kubonakala phantsi kwe-microscope, iiflake zegraphite zibonakala njengemigca emihle. Iingcebiso zeeflakes zisebenza njengamanotshi asele ekhona; ngoko ke, ibhityile. Ubukho be graphite flakes benza i-Grey Iron ikwazi ukucatshukiswa lula njengoko zithanda ukuqhekeka ngokulula kwiiflake zegraphite. Intsimbi engwevu ikwanesakhono sokumanzisa kakuhle kakhulu kwaye yiyo loo nto isetyenziswa kakhulu njengesiseko sokunyuswa kwezixhobo zoomatshini.
