Lehlabathe la foundry kudu le akaretša mehuta ye e latelago:
1.Silica lehlabathe: The ka sehloohong diminerale sebopeho ke SiO2.Silica lehlabathe ka ho feta arotsoe ka tlhaho silica lehlabathe,kgethile tlhaho lehlabathe le maiketsetso silica lehlabathe. Natural silica lehlabathe e sebediswa e le bōpa le konokono lehlabathe bakeng sa bao e seng - ferrous motsoako lahlela,cast tšepe dikarolo ,small lahla dikarolo le mahareng -sized tšepe costings.Selected tlhaho silica lehlabathe e sebediswa bakeng sa fapaneng bōpa lehlabathe le konokono lehlabathe le metsoako manyolo e le binders.Artificial silica lehlabathe e sebediswa e le bōpa lehlabathe le konokono lehlabathe bakeng sa tšepe di-castings tše di lahlilwego
. E tloaelehile sebediswa ka lahla,fireproof thepa.metallurgy.khemikhale indasteri le masimo a mang.Kalaka lehlabathe e entsoe ka ho pšhatla kalaka ,ka ka sehloohong diminerale sebopeho e le CaCO3.E sebediswa e le bōpa lehlabathe le konokono lehlabathe bakeng sa tšepe castings.Ho phaella moo,ho na le chromite lehlabathe,olivine lehlabathe ,dipheta lehlabathe. bjalobjalo.
3.Special sand: when the high-temperature performance of silica sand can't meet the requirements for use,special sand such as zircon sand,chromite sand and corundum sand are used.For example, zircon sand,whose main mineral component is ZrO2, e sebediswa e le lehlabathe konokono kapa holim lehlabathe kapa phofo tlotsa bakeng sa kgolo lahletsoeng tšepe le motsoako tšepe parts.The diminerale ka sehloohong tsa chromite lehlabathe ke chromite,magnesiochromite le aluminium magnesium chromite le sebopeho lona ka sehloohong lik'hemik'hale e ikemiseditse ho ba Cr2O3.Sebopego se segolo sa diminerale sa santa ya corundum ke - Al2O3,eo e sebediswa e le khetla thepa bakeng sa dipeeletso lahla le ceramic hlobo lahla.
Ka kakaretso, ho na le mefuta e fapaneng os lahlela lehlabathe ,le mefuta e fapaneng ya lahla lehlabathe ba loketseng bakeng sa dithulaganyo fapaneng casing le lahla types.When khetha lahla lehlabathe,ho hlokahala hore ho latela itseng lahla ditlhoko le maemo a.
