一、前言在钛冶金中,残钛回收一直是国内外关注的研究课题。我国冶炼厂的残钛——锅巴海绵钛,过去只是用作脱氧剂,利用量小,积压甚多,致使钛制件价格昂贵,限制了它的应用范围。在回收残钛的问题上,国内外曾先后采用了残钛压入电极法、间隙加料真 First, the preface Titanium Metallurgy, residual titanium recovery has been the subject of research at home and abroad. China’s smelter’s residual titanium - caramel sponge titanium, the past is only used as a deoxidizer, the use of small, a lot of backlog, resulting in expensive titanium parts, limiting its scope of application. In the recovery of residual titanium on the issue, both at home and abroad have adopted a residual titanium electrode method, the gap feed really
