| Abstract: | This paper is concerned with a gassing controller developed by the authors that is capable of performing three different modes of gassing, namely, continuous, pulse and manually-operated gassing, and with two controlling functions, gas pressure and flow rate control. Pulse gassing and its optimum technology have been investigated. The results show that the total amount of CO2 consumed in the pulse gassing can be reduced by 50% with the properties of the core sand remaining unchanged. If the optimum gassing technology is used in its stead, the silicate addition will be reduced to 3.0~4.0% under appropriate conditions. |
