Titanium slab for hot rolling produced by electron-beam melting furnace, process for production thereof, and process for rolling titanium slab for hot rolling

摘要: A titanium slab is appropriate for hot rolling, produced by electron beam melting furnace, has superior linearity so that it can be fed into a rolling machine without performing breaking down process or other subsequent correcting after production, and good structure having no cracks at the corner parts. production thereof also provided. The directly mold of an deformation not more than 5 mm thickness direction versus longitudinal 2.5 width direction, both per length 1000 slab. this step using furnace in which its rectangular walls long side short side, pouring molten metal from one side. Furthermore, chamfered parts used process.
