摘要: A method for producing titanium alloy by the reduction of titanium tetrachloride and alloy components with a reducing metal agent, capable of continuously producing titanium alloy on an industrial scale. The temperature and pressure of the reaction zone for the reduction are kept above a melting point of the titanium alloy and above the vapor pressure of the reducing metal agent at that temperature respectively, so that the reducing metal agent and its chloride may be kept in a molten state but without boiling.

摘要: A method for producing metal by the reduction of a metal halide by a reducing metal agent capable of continuously producing homogeneous metal of high purity. In the method, particles of the same metal as the metal to be produced are charged into a reaction vessel and the metal halide and the reducing metal agent both in vapor form, are ejected upwards into the reaction vessel from its lower portion to form a fluidized bed of the metal particles in the vessel. The reducing reaction between the two vapors takes place on the surface of the metal particles at a temperature below the melting point of the metal product and at a pressure below a vapor pressure of each of the reducing metal agent and the metal halide at that temperature, resulting in depositing and growing the metal product on the surface of the particles.

摘要: Porous plate 13 is disposed between wind box 11 of dispersion board B and cylindrical vessel wall 12. Filling layer 14 of a structure packed with ceramic particles such as those of fused silica is disposed on the porous plate 13 so as to fill the inside of the cylindrical vessel wall. The filling layer 14 is composed of ceramic particles, so that the corrosion wear by chlorine gas can be inhibited and the durability thereof enhanced. Furthermore, a chlorine resistant member is disposed in a form so as to adhere to the internal surface of the cylindrical vessel wall 12, so that the corrosion wear by chlorine gas of the cylindrical vessel wall 12 can also be effectively inhibited. As a result, damage to the internal wall of the chlorination furnace can be minimized, and the state of allowing chlorine gas to be uniformly dispersed and supplied to fluidized bed 4 containing titanium ore and coke can be maintained for prolonged periods.
