By Tao Jiang, Jiann-Yang Hwang, Gerardo R. F. Alvear Flores, Onuralp Yucel, Xinping Mao, Hong Yong Sohn, Naiyang Ma, Phillip J. Mackey, Thomas P. Battle

The research, improvement, and/or operation of extreme temperature tactics that contain the construction of ferrous and nonferrous metals, alloys, and refractory and ceramic fabrics are coated within the booklet. The leading edge tools for reaching impurity segregation and elimination, derivative restoration, waste minimization, and/or strength potency also are concerned. 8 issues are provided within the book:

1: excessive potency New Metallurgical method and Technology
2: primary study of Metallurgical Process
3: Alloys and fabrics Preparation
4: Direct aid and Smelting Reduction
5: Coking, New power and Environment
6: usage of reliable Slag/Wastes and intricate Ores
7: Characterization of hot temperature Metallurgical Process

L XRD of Alloy Added Different Amounts of CaFe, SiFe Fig 1 was the XRD pattern of high titanium ferroalloy prepared by the method of sub-step reduction with different amounts of ferrosilicon, ferrocalcium as agents. 6%,CaFe 3%. and the amount of ferrosilicon arose, Si and Ti, Fe combined to generate FeTiSi, TigO appeared in sample 3#, and TiO and TiiOs appeared in sample 5#, which indicated reduction bad effect with ferrosilicon as agent in the reactions and was easy to generate slag phase such as Si0 2 comparing with sample 3# and sample 5#.

In China, titanium ferroalloy used in refining the special steel was almost low- titanium ferroalloy, which is a big gap compared with developed countries [6 l It also seriously affects the improvement of the quality of steel, especially stainless steel. For moment, the doped remelting was the main way to produce high titanium ferroalloy in our country. This method took scrap titanium or titanium sponge as the main raw material, which had a high production costs and relayed greatly on the price and sources [7'SI of scrap titanium.
