Ceramic foundry sand bakeng sa ts'ebetso ea lehlabathe le letala

Green Sand Castings are castings made using wet sand or “green sand” molds. The sand is not green in color nor do the molds use “greensand,” a greenish color sandstone. Instead of the sand is called “green” because it has moisture in it (like green wood) before the sand dries out when molten metal is poured in the mold.

What gives the sand moisture and helps the sand stick together when making molds is the clay that is mixed in the sand. Bentonite clay and the sand mixed together provide strong molds that can be created on an automated assembly line.

Lehlabathe la sintered ceramic foundry le entsoe haholo ka liminerale tse nang le Al2O3 le SiO2 mme li eketsoa ka lisebelisoa tse ling tsa liminerale. Lehlabathe la motheo la spherical le entsoeng ka phofo, pelletizing, sintering and grading process. Sebopeho sa eona se ka sehloohong sa kristale ke Mullite le Corundum, e nang le sebōpeho sa lijo-thollo se chitja, ho hanyetsa ho phahameng, botsitso bo botle ba thermochemical, katoloso e tlaase ea mocheso, tšusumetso le ho hanyetsa abrasion, likarolo tsa ho arohana ho matla. Ha lehlabathe la ceramic le sebelisoa ts'ebetsong ea lehlabathe le letala, le ka eketsa linako tse sebelisoang hape lehlabathe le tala, la fokotsa tlhahiso ea lehlabathe la litšila, le ntlafatsa tlhahiso ea lihlahisoa.
