RESEARCH ON AS-CAST GRAIN REFINING TECHNOLOGY BY INOCULATING CLEAN STEEL WITH TITANIUM OXIDE M.L.Wang1,P.Zhao1,Y.G.Wang2,G.G.Cheng2,X.E.Yang2,L.Y.Wang2,Y.L.Li2 (1.Central Iron and Steel Research Institute, Beijing 100081, China;2.University of Science and Technology Beijing, Beijing 100083, China) Abstract:Precipitation condition and nucleation of Ti2 O3 during solidification of clean steel......
of leakages. It results from exposure to various kinds of chemical steam and saline environment. Also it lets down durability and feasibility[1-2]. To fix them, titanium material was employed as plate heat exchanger element. The titanium is relatively more expansive than other light metal, so it is too difficult to be adapted to plate heat exchangers. Hence, low cost as well as high efficiency can......
