Ramel tal-funderija taċ-ċeramika għall-proċess tar-ramel aħdar

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.

Ir-ramel tal-funderija taċ-ċeramika sinterizzat huwa magħmul prinċipalment minn minerali li fihom Al2O3 u SiO2 u miżjud ma 'materjali minerali oħra. Ramel tal-funderija sferiku magħmul minn proċessi ta 'trab, pelletizing, sinterizzazzjoni u gradazzjoni. L-istruttura tal-kristall prinċipali tagħha hija Mullite u Kurundun, b'forma ta 'qamħ fit-tond, refrattarija għolja, stabbiltà termokimika tajba, espansjoni termika baxxa, reżistenza għall-impatt u l-brix, karatteristiċi ta' frammentazzjoni qawwija. Meta r-ramel taċ-ċeramika applikat fil-proċess tar-ramel aħdar, jista 'jżid il-ħinijiet tar-ramel mhux ipproċessat użat mill-ġdid, inaqqas l-emissjonijiet tar-ramel tal-iskart, ir-rendiment imtejjeb tal-ikkastjar.
