Foundry jecha rinonyanya kusanganisira anotevera marudzi:
1.Silica jecha: Iyo huru yemaminerari inoumbwa iSiO2.Silica jecha rinogona kuwedzera kugoverwa kuva silika jecha, yakasarudzwa yakasarudzika jecha uye yakagadzirwa silica jecha. Natural silica jecha rinoshandiswa kuumba uye core jecha kune zvisiri-ferrous alloy casting, cast iron parts , small casting parts and medium{4}}size simbi costings.Selected natural silica jecha rinoshandiswa kuumba zvakasiyana-siyana jecha uye core sand rine organic compounds sezvisunga.
2.Non siliceous jecha: kusanganisira marudzi akasiyana-siyana akadai sejecha re quartz, jecha re limestone, etc.Quartz jecha chinhu chegranular chinogadzirwa nekupwanya dombo re quartz sechinhu chikuru chakasvibirira, chine ruvara rwemukaka chena kana semi transparent. Inowanzoshandiswa mukukanda,fireproof material.metallurgy.chemical industry nemamwe mafields.Limestone jecha rinogadzirwa nekupwanya limestone,ine chicherwa chikuru cheCaCO.3.Inoshandiswa sejecha rekuumba uye jecha repakati resimbi castings.Kuwedzera, kune chromite jecha,olivine jecha,bead jecha. etc.
3.Special jecha: kana tembiricha yepamusoro-yejecha resilica isingakwanisi kuzadzisa zvinodiwa pakushandisa, jecha rinokosha rakadai sejecha rezircon, jecha rechromite nejecha recorundum rinoshandiswa. Semuyenzaniso, jecha rezircon, rine chikamu chikuru chezvicherwa chinonzi ZrO.2, inoshandiswa sejecha musimboti kana jecha repamusoro kana poda yekuputira yesimbi yakakura yakakandwa uye alloy simbi zvikamu.Maminerari makuru ejecha rechromite chromite, magnesiochromite uye aluminium magnesium chromite uye chimiro chayo chikuru chemakemikari chakatsunga kuve Cr.2O3.Chicherwa chikuru chejecha recorundum - Al2O3, iyo inoshandiswa segoko rekudyara kwekudyara uye kukanda ceramic mold.
Pakazere, kune marudzi akasiyana-siyana os kukanda jecha, uye marudzi akasiyana ejecha rekukanda akakodzera kune akasiyana casing maitiro uye kukanda mhando.
Isu tinogadzira uye nekutumira kunze - zvemhando yepamusoro mullite foundry jecha, hupfu hwemufushi nehupfu
