Ceramic foundry jecha regirini jecha process

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.

Sintered ceramic foundry jecha rinonyanya kugadzirwa nemaminerari ane Al2O3 uye SiO2 uye anowedzerwa nemamwe mamineral zvinhu. A spherical foundry jecha rakagadzirwa nehupfu, pelletizing, sintering uye grading maitiro. Yayo huru yekristaro chimiro ndeye Mullite uye Corundum, ine yakatenderedzwa zviyo chimiro, yakakwirira refractoriness, yakanaka thermochemical kugadzikana, kuderera kwekuwedzera kwemafuta, kukanganisa uye abrasion kuramba, maficha ekutsemuka kwakasimba. Kana jecha receramic rinoshandiswa mukugadzira jecha rakasvibirira, rinogona kuwedzera jecha rakasvibira rakashandiswazve nguva, kuderedza tsvina yejecha kubudiswa, nekuvandudza goho rekukanda.
