Abstract：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.
