A TiCl 4 gas is supplied to a molten CaCl 2 liquid held in a reactor vessel 6 through a raw material feed pipe 11, TiCl 4 is reduced to produce granular metallic Ti by Ca melted in the CaCl 2 liquid. The molten CaCl 2 liquid in which Ti granules taken out downward from the reactor vessel 6 is mixed is delivered to a separation process 12, the molten CaCl 2 liquid is heated in a heating vessel 15, and separation is generated by a difference in specific gravity, whereby the molten CaCl 2 liquid 16 is located in an upper layer while a metallic Ti 17 is located in a lower layer. The metallic Ti 17 in the lower layer is taken out from a high-melting-point metal discharge port 18, and the metallic Ti 17 is solidified to yield an ingot. The molten CaCl 2 liquid 16 in the upper layer is delivered to an electrolysis process 13 along with the molten CaCl 2 liquid taken out from the reactor vessel 6, and Ca generated by the electrolysis and CaCl 2 are returned into the reactor vessel 6. A separation and recovery method of the invention is applied to the separation process 12 in the above production process, and high-quality Ti or Ti alloy is efficiently separated and recovered from the CaCl 2 -containing molten salt with a small amount of energies

摘要:
By subjecting a threaded joint for OCTG (oil country tubular goods) to surface conditioning with an aqueous solution of potassium tetraborate or sodium tetraborate prior to manganese phosphate chemical conversion treatment, a manganese phosphate chemical conversion coating having coarse crystal grains with an average crystal grain diameter of 10 - 110 micrometers is formed on the surface of the steel member which may be any steel including a high Cr steel. This manganese phosphate chemical conversion coating can hold a large amount of a liquid lubricant, and it is effective at preventing the occurrence of galling at the time of makeup of a threaded joint for OCTG.
