Description

연속 제조된 미세 티타늄 스폰지의 직접 성형장치{APPARATUS FOR DIRECT MOLDING MICRO TITANIUM SPONGE PRODUCED CONTINUOUSLY}Direct Forming Apparatus for Continuously Producing Fine Titanium Sponge

본 발명은 미세 티타늄 스폰지를 성형하는 장치에 관한 것으로서, 보다 상세하게는 연속적으로 제조된 미세 티타늄 스폰지를 분리, 배출시켜 주조하여 성형하는 공정없이 직접 성형할 수 있는 장치에 관한 것이다.
The present invention relates to an apparatus for molding a fine titanium sponge, and more particularly, to an apparatus that can be directly molded without the process of separating, discharging and casting the continuously produced fine titanium sponge.

티타늄 스폰지는 통상적으로 크롤(Kroll)법에 의해 제조되며, 이는 통상 철제의 반응용기 내에서 액상 마그네슘과 기상 사염화티타늄의 반응에 의해서 제조된다. 상기 크롤(Kroll)법은 반응용기 내에서 환원반응과 진공증류의 두가지 공정을 거쳐서 티타늄 스폰지를 제조하는 공정이다. 현재 상기 환원반응과 진공증류의 두가지 공정이 분리되어 제조시간이 많이 소요되는 문제점이 있다.
Titanium sponge is usually produced by the Kroll method, which is usually produced by the reaction of liquid magnesium and gaseous titanium tetrachloride in an iron reaction vessel. The Kroll method is a process for producing a titanium sponge through two processes of reduction reaction and vacuum distillation in a reaction vessel. At present, there are problems in that the two processes of the reduction reaction and vacuum distillation are separated, which takes a lot of production time.

티타늄 스폰지의 제조와 관련된 선행기술로는 일본공개특허 1993-311266호, 미국공개특허 2002-309552호 및 유럽공개특허 0299791호 등이 있다. 상기 특허들에서는 상기 환원반응을 통해서 미세 티타늄 스폰지를 형성하고, 생성된 미세 티타늄을 티타늄 융점 이상으로 재용해한 후 생성된 티타늄 잉곳을 축출하는 방법을 제시하고 있다.
Prior arts related to the production of titanium sponges include Japanese Patent Laid-Open No. 1993-311266, US Patent No. 2002-309552, and European Patent No. 0299791. The patents propose a method of forming a fine titanium sponge through the reduction reaction, dissolving the produced fine titanium above the melting point of titanium, and then discharging the produced titanium ingot.

그러나, 상기 특허들은 티타늄 스폰지를 이용하여 잉곳을 추출하는 방법에 국한된 것이고, 미세 티타늄 스폰지를 성형하는 기술에 대해서는 언급된 바 없다. 통상적으로 티타늄 성형품을 제조하기 위해서는 상기 특허들로 제조된 티타늄 잉곳을 추출하여 별도의 성형장치로 이송하여 성형하게 된다.
However, the patents are limited to the method of extracting the ingot using a titanium sponge, and there is no mention of a technique for forming a fine titanium sponge. In general, to manufacture a titanium molded article, the titanium ingot manufactured by the above patents is extracted and transferred to a separate molding apparatus to be molded.

따라서, 반응용기에서 생성된 티타늄 스폰지를 추출하고, 이를 성형장치에 이송하고, 다시 가열 및 가압하여 성형하는 공정을 거치게 되면, 티타늄 스폰지에 불순물이 첨가되어 품질의 저하를 야기할 수 있으며, 추가적인 가열, 가압하는 공정으로 인해, 많은 에너지가 필요하게 되고, 이는 가격인상의 요인이 되므로, 경쟁력을 저하시키는 문제가 있다.
Therefore, if the titanium sponge produced in the reaction vessel is extracted, transferred to the molding apparatus, and heated and pressed again to form a process, impurities may be added to the titanium sponge to cause deterioration of quality and additional heating. Due to the pressurizing process, a lot of energy is required, which causes a price increase, thereby lowering the competitiveness.

본 발명의 일측면은 연속적으로 제조되는 미세 티타늄 스폰지를 분리, 배출하여 주조하는 공정없이 성형함으로써 경제적이고, 균일한 품질의 티타늄 성형체를 연속적으로 제조할 수 있는 미세 티타늄 스폰지의 성형장치를 제공하는 것이다.
One aspect of the present invention is to provide a molding apparatus for fine titanium sponge that can continuously produce a economical, uniform quality titanium molded body by molding without the process of separating, discharging and casting a fine titanium sponge produced continuously. .

It is provided so as to be connected downstream of the reduction furnace, and provides a direct molding apparatus of a continuously manufactured fine titanium sponge comprising a molding unit for molding the titanium sponge.

본 발명에 의하면, 크롤(Korll)법에 의해 연속적으로 제조된 미세 티타늄 스폰지를 직접 성형함으로서, 에너지 절약이 가능하며, 시간적, 경제적 측면에서 유리할 뿐만 아니라, 품질이 우수한 티타늄 성형체를 제공할 수 있는 효과가 있다.
