Abstract

В производстве Ti или сплава Ti посредством восстановления кальцием (Са) солевую электролитную ванну, отведенную из процесса восстановления, подвергают электролизу для извлечения Са и солевой электролитной ванны в виде твердого вещества, и извлеченные Са и солевую электролитную ванну направляют в процесс восстановления. Следовательно, выделение теплоты в процессе восстановления подавляется за счет использования скрытой теплоты плавления, которой обладает твердое вещество, посредством чего значительно улучшаются эффективность производства и термический КПД. Кроме того, легко регулируется температура реакции и может быть увеличена скорость подачи исходного материала для эффективного производства Ti или сплава Ti. При этом, используя способ электролиза с вытягиванием по изобретению, Са и солевая электролитная ванна в твердом состоянии могут быть получены при низком напряжении и высоком выходе по току, т.е. с относительно низким потреблением электроэнергии. При использовании смеси Са и солевой электролитной ванны в твердом состоянии в качестве источника Са в производстве Ti или сплава Ti посредством восстановления Са могут эффективно производиться Ti или сплав Ti.In the production of Ti or Ti alloy by calcium (Ca) reduction, the electrolyte salt bath withdrawn from the reduction process is subjected to electrolysis to recover Ca and the electrolyte salt bath as a solid, and the recovered Ca and the electrolyte salt bath are sent to the reduction process. Therefore, the generation of heat in the reduction process is suppressed by using the latent heat of fusion that the solid has, whereby production efficiency and thermal efficiency are greatly improved. In addition, the reaction temperature is easily controlled and the feed rate of the starting material can be increased to efficiently produce Ti or Ti alloy. However, by using the drawing electrolysis method of the invention, Ca and a solid state salt electrolyte bath can be obtained at low voltage and high current efficiency, i. E. with relatively low power consumption. By using a mixture of Ca and a solid state salt bath as a Ca source in the production of Ti or a Ti alloy, Ti or a Ti alloy can be efficiently produced by reducing Ca.
