本文主要是針對新式轉爐，從熔解原理、製程參數及冶金品質作整體性的評估，使國人能對此新式熔解爐有更多的瞭解。
首先是介紹轉爐之設備裝置及操作原理，對於轉爐操作程序、配料種類、燃燒設定及廢氣之排放作一介紹，然後對轉爐熔解過程中的反應機構進行分析，以了解熔解過程中燃料及合金元素的相關反應。最後進行製程參數與冶金特性之研究。
實驗結果顯示，回爐料、鋼料及車削屑均可作為轉爐熔解之配料，但須注意其進料順序。合金元素之回收率，除碳大致維持在一範圍外，矽、錳之回收隨回爐料及鋼料比例增加而降低。合金元素添加時，碳與配料一同加入效果不佳，需待熔液完全熔解後，將碳置入熔液中較具效果，其他矽、錳等隨配料加入，回收情形與配料中元素相似。使用轉爐所生產之鑄件其機械性質及金相組織合於規範之要求，但由於其硫化物等含量低，其伸長率則遠大於標準值。

To provide more understanding of rotary furnace, principles of melting, process parameter and the quality of metallurgy are assessed in this study.
Installation and manipulation principles of rotary furnace are introduced first, including manipulation procedure, kinds of charges, combustion setting and fume exhaust. Reactions in melting cycles are then analyzed to evaluate the interaction between fuel and alloy elements. Finally, I investigate the manufacture parameters and characteristcs of metallurgy.
Results show that returns, steel scrap and turning chips could be used as charges, but the charging sequence deserves attention. The recovery of silicon and manganese decrease with addition of return and steel scrip, but recovery of carbon maintains unchangeable. When recarbonrizing, recovery is low with recarbonrisers and charges added simultaneously. It's better to recarbonrize when all of charges are melted. Recovery of ferrosilicon and ferromanganese are similar with other charges. The mechanical properties and microstructure of cast produced from rotary furnace are standard. But with low inclusion, elongation is achieved better than the standard.
