减压操作技术分析

Technology Analysis on Decompression Operation

针对减压操作———真空和稀释在钢液冶金应用的共性问题进行了综合分析和讨论:真空与减压;真空的冶金直接效应;真空对气体搅拌的影响;降低分压技术的成功应用———AOD法冶炼不锈钢;降低总压技术———真空碳脱氧和真空氧脱碳;真空对耐火材料的影响;真空冶金装置。

The common problems of appllying the decompression operations including vacuum and dilution in molten steel are analysed and discussed;these contain vacuum and decompression;the direct metallurgy effect of vacuum;the influence of vacuum on gas stirring;partial pressure decompression technics the successful applicationful of total pressure decompression technics stainless steel smelted by AOD method;vacuum carbon-deoxidization and vacuum oxygen-decarburization; the influence of vacuum upon refractory; the vacuum metallurgy equipment.
