    摘要： The present invention provides an electron-beam furnace and a melting method that, in producing an ingot by melting a metal with an electron beam, can suppress the contamination of new impurities in the ingot production, are less likely to again result in inclusion of once evaporated impurities from a molten metal pool within a hearth or a mold, and can be improved in utilization rate. The electron-beam furnace for melting a refractory metal includes a feeder unit for raw materials, a melting unit for raw materials, which is connected to the feeder unit for raw materials and, at the same time, is defined by a furnace wall and a ceiling wall, and includes at least a hearth, a water-cooled mold, and an electron gun, and an evacuation unit for exhaust gas connected to the melting unit for raw materials. In this electron beam furnace, at least one of the furnace wall and the ceiling wall is lined with titanium or stainless steel, and in addition, plural fin-shaped members formed of titanium or stainless steel are provided at the ceiling wall. A lining, which can be attached and detached, is provided on the inner face of the electron beam furnace.

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