본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

Claims (8)

일반적으로 잔류 마그네슘 및 마그네슘 클로라이드를 제거하기 위하여 증류된 금속지르코늄 스펀지를 지르코늄 테트라클로 라이드를 환원시켜 제조하고, 증류된 잉곳을 용융하여 잉곳을 제조하는 정제형의 지르코늄을 제조하는 방법에 있어서, 120-400℃에서 적어도 1시간 반동안 증류된 스펀지를 진공으로 베이크하고, 진공 베이크된 스펀지를 전자비임으로 용융하는 것을 특징으로 하는 방법.In general, a method of producing a tablet type zirconium in which distilled metal zirconium sponge is prepared by reducing zirconium tetrachloride to remove residual magnesium and magnesium chloride, and melting the distilled ingot to produce an ingot, And baking the vacuum distilled sponge at 400 ° C. for at least one and a half hours in a vacuum, and melting the vacuum baked sponge in an electron beam. 제1항에 있어서, 진공 베이크된 스펀지가 일반적으로 진공 베이킹 및 EB용융 사이에서 비활성 분위기하에 유지되는 것을 특징으로 하는 방법.The method of claim 1 wherein the vacuum baked sponge is generally maintained in an inert atmosphere between vacuum baking and EB melting. 제2항에 있어서, 진공 베이킹이 용융하기전에 EB노 내에서 수행된 후, EB용융이 진공 상태로 수행되는 것을 특징으로 하는 방법.The method of claim 2, wherein the vacuum baking is performed in an EB furnace before melting, followed by EB melting in a vacuum state. 제3항에 있어서, EB회전 급송노가 이용되고, 스펀지는 전극으로 병합되지 않고 용융되는 것을 특징으로 하는 방법.4. A method according to claim 3, wherein an EB rotary feed furnace is used and the sponge is melted without merging into the electrode. 제3항 또는 제4항에 있어서, EB노가 다중소사 비임으로 구성되는 것을 특징으로 하는 방법.The method according to claim 3 or 4, characterized in that the EB furnace consists of a multi-source beam. 제3항, 제4항, 또는 제5항에 있어서, EB용융된 스펀지가 진공 아크의 다중통로에 의해 용융되는 것을 특징으로 하는 방법.6. The method of claim 3, 4 or 5, wherein the EB melted sponge is melted by multiple passages of a vacuum arc. 제1항에 있어서, 진공 베이크된 스펀지가 진공베이킹 및 EB용융 사이의 분위기하에 1시간 이하로 노출되는 것을 특징으로 하는 방법.The method of claim 1, wherein the vacuum baked sponge is exposed to an atmosphere of no more than 1 hour in an atmosphere between vacuum baking and EB melting. 제1항 내지 제7항중의 어느 한 항에 있어서, 증류된 스펀지가 시험된바, 600ppm 이하의 산소를 함유한 스펀지만을 사용하는 것을 특징으로 하는 방법.8. Process according to any one of the preceding claims, wherein only distilled sponges have been tested and only sponges containing up to 600 ppm of oxygen are used. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
