熱鍛免調質棒鋼開發與改善* Development and Improvement of Forging Steel Requiring no Further Quenching and tempering 1 2 3 S.L.Liang, C.Y.Kuo, K.L.Chang This article describes the development and improvement of forging steel that does not need further quenching and tempering. V Ti By adding V, Ti and other alloy elements and by a new controlling rolling technology, the strength and toughness of forging steel have been enhanced. By means of proper cooling controlling after forging process, the mechanical properties of improved forging steel are better than that of regular quenched and tempered steels. The improved forging steel saved energy, decreased carbon 10~ 15% emissions, and reduced customer processing costs by 10 to 15%. 關鍵詞： Key words: Free of quenching and tempering processes after hot forging 一、前　　言 10~ 15% 二、鍛件加工與用途 1 1(S45C) *103 1,2 3 1,2 3 Engineer, Metallurgical Department, Scientist, Iron and Steel R D Department, China Steel Corporation 鑛冶 59/1 －29 － 2 2 3 Hub 4 3 4(Hub) －30 －
