钢液中溶解有大量气体吗?

On Whether There Is Large Amount of Gas Dissolved in Molten Steel

西北工业大学出版社出版的由姚泽坤教授主编的《锻造工艺学与模具设计》书中说“钢液中溶解有大量气体”。事实上,钢液中的气体主要为氧、氢、氮,且含量极小。同时,炼钢过程中会采用一些措施去除钢液中的气体,因此该说法欠妥。

In Forging Technology and Die Design compiled by professor Yao Zhaokun and published by Northwest Industrial University press, it is stated that there is a large amount of gas dissolved in molten. In fact, the gases dissolved in molten steel are mainly oxygen, hydrogen and nitrogen of a very small amount. Besides, measures are taken to get rid of the gases in molten steel in the process of steelmaking. Therefore, this statement is not appropriate.
