在很宽的钢水质量范围内对包括钢包炉和多种真空处理在内的二次冶金工艺的成本进行了分析,并对两种常用的真空泵系统进行了比较。干式机械真空泵在最多360t的整个钢水质量范围内都具有明显的成本优势,节约的幅度随工艺而变化,具体同能源（无论何种形式）的供应和设备的产能有关。通过快速抽真空缩短处理的周期时间,降低了钢水的过热需要,从而降低了生产成本,提高了产能,改善了质量。
The cost for the conversion of steel in secondary steelmaking including a ladle furnace and various vacuum treatment processes have been investigated for a large heat range and comparing two commonly used vacuum pump systems.Dry operating mechanical vacuum pumps offer substantial savings over the whole melt mass range up to 360 t.Such savings differ for the various processes and depend upon the availability of energy,in whatsoever form,as well as upon the plant productivity.The shortening of treatment cycle time by a rapid pump down limits the melt overheating and thus leads to savings in production cost,increased productivity and quality improvement.
