Ceramic foundry xuab zeb rau ntsuab xuab zeb txheej txheem

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 xuab zeb yog tsim los ntawm cov zaub mov uas muaj Al2O3 thiab SiO2 thiab ntxiv nrog lwm cov khoom siv ntxhia. Spherical foundry xuab zeb ua los ntawm hmoov, pelletizing, sintering thiab grading txheej txheem. Nws cov qauv siv lead ua tseem ceeb yog Mullite thiab Corundum, nrog cov duab zoo sib xws, siab refractoriness, zoo thermochemical stability, tsis tshua muaj thermal expansion, cuam tshuam thiab abrasion tsis kam, muaj zog fragmentation. Thaum cov xuab zeb ceramic siv rau hauv cov txheej txheem xuab zeb ntsuab, nws tuaj yeem ua rau cov xuab zeb nyoos rov siv dua, txo cov xuab zeb pov tseg, txhim kho cov khoom pov tseg.
