    摘要： PROBLEM TO BE SOLVED: To provide a method for producing a titanium ingot using a vacuum arc melting furnace by which a titanium ingot having high purity, good casting surface and high productivity is produced.
    SOLUTION: The method for producing the titanium ingot uses the vacuum arc melting furnace which generates an arc between molten metal held in a mold and a consumable electrode to melt the consumable electrode, thereby forming the ingot in the mold. The method is characterized in that an arc gap (a distance from the lower end of the consumable electrode to the molten metal surface) is changed according to kinds of titanium to be melted. When the ingot to be produced is titanium alloy, melting is performed with a smaller arc gap than an average arc gap (the arithmetic average of the maximum arc gap value and the minimum arc gap value in a range where the vacuum arc melting can be performed), and when the ingot to be produced is pure titanium, the melting is performed with a larger arc gap than the average arc gap.

    摘要翻译： 要解决的问题：提供一种使用真空电弧熔化炉制造钛锭的方法，通过该方法制备了具有高纯度，良好铸造表面和高生产率的钛锭。 解决方案：钛锭的制造方法使用真空电弧熔化炉，其在保持在模具中的熔融金属和消耗电极之间产生电弧，以熔化可消耗电极，从而在铸模中形成锭。 该方法的特征在于，根据要熔化的钛的种类，电弧间隙（从可消耗电极的下端到熔融金属表面的距离）发生变化。 当要生产的锭是钛合金时，以比平均电弧间隙更小的电弧间隙进行熔化（在可以进行真空电弧熔化的范围内的最大电弧间隙值和最小电弧间隙值的算术平均值） ），并且当要生产的锭是纯钛时，以比平均电弧间隙大的电弧间隙进行熔化。 版权所有（C）2010，JPO＆INPIT
