| Abstract: | Two degassing plates made of different materials were studied.Effects of gas permeability of degassing plate were examined by altering the organic additives content and process parameters.The bubble distribution state of the special graphite degassing plate was also investigated.In the end,the process parameters were optimized through water simulation.The results show that the purging bubbles from two degassing plates are very fine and uniformly distributed and the bubble amount is appropriate.The two degas... |
