奥氏体合金铸铁增碳的试验研究

Carbon Pick up of Austenitic Alloy Irons

采用工业试验的方式对奥氏体合金铸铁增碳效果进行了研究，确定了中频感应炉熔化，炉底加入增碳剂Ｇ５０，Ｇ６０，控制铁水温度在１３８０～１４００℃，增碳时间为１５ｍｉｎ，获得了增碳的较佳效果．

The effect of carbon pick up was studied by means of the industrial experiment. Under the optimal operation condition,the iron was melt in a intermediate frequency furnace,and carbon pick up (G 50,G 60) was added to the bottom of the furnace. The temperature of molten iron was 1350～1400℃ and the carbon pick up time was 15 minutes. The carbon pick up result obtained was much better than other experiments.
