| Abstract: | With increasing temperature,water glass and quartz sand will combine firmly to form caking which makes the shakeout process very difficult. In this paper,by applying x-ray diffractometer and acanning electronic microanalyser,structure of water glass and its configuration,and the interaction between water glass and quartz sand are investigated. Finally,the machnism of caking has been discussed. |
