VD真空精炼技术与装备的发展

Development of the Vacuum Degassing Technology and its .Equipment

介绍了VD真空精炼技术的发展，指出VD功能多元化应是今后发展的主要趋势，提出重点研究开发氧脱碳（碳脱氧）、深脱硫、深脱气技术是实现VD功能多元化的关键。在此基础上，介绍了高效化生产装备和干式机械泵系统应用于VD真空精炼的情况，指出干式机械泵系统应用于真空精炼是一种可行的选择。

The paper introduced the VD vacuum refining technology development, pointed out that the VD muhifunction should be development trend in future, to focus on the research and development of oxygen decarburization （Carbon deoxidized）, deep desulfurization, deep degassing technology is to realize VD plurality of function key. On this basis, introduced the high efficient production equipment and dry mechanical pump system used in VD vacuum refining situation, pointed out that the dry mechanical pump system used in vacuum refining is a viable option.
