摘要
研究 7B0 4合金中形成氧化膜的原因 ,在采用高效除气和过滤工艺 ,有效除去非金属氧化物和氢的同时 ,重点解决了净化后熔体供流转注过程中的二次污染问题 ,有效防止 7B0 4合金铸锭氧化膜缺陷的产生 ,提高了 7B0 4合金材料成材率。
Cause of formation of oxide film on 7B04 alloy are studied in this article.Non-metal oxide and hydrogen are removed efficiently,re-pollution problems are also solved during transmitting melt after purifying,using efficient degassing and filtration process.Oxide film defects on 7B04 alloy ingot are prevented effectively,the percentage of finished product of 7B04 alloy materials is increased.
