Average foaming life and foaming intensity of foaming process originated from reaction

对平均发泡寿命和发泡强度的定义和适用条件进行了分析 ,并辅以发泡和消泡系数来定量描述内生气源条件下熔体的发泡行为。利用碳酸盐分解产生的内生气源在Na2 B4 O7熔渣中发泡方程的简化公式和试验数据可以确定在坩埚直径、渣高度和发泡剂的粒度变化时的发泡和消泡系数及平均发泡寿命和发泡强度 。

The average foaming life and foaming intensity have been defined and their application were discussed. With these two parameters and the supplement formation and rupture coefficients, the foaming process originated from the reaction in the melt can be described quantitatively. By simplifying foam equation of decomposition of the carbonate in borate melt and with the experimental data, the four coefficients for foaming process can be determined in the variations of crucible diameter, slag height and foaming agent radius. In this way the foam behavior of foaming process under different conditions can be compared quantitatively. [
