Description
본 발명은 연속주조식 발포 알루미늄금속의 제조방법 및 그 장치에 관한 것으로서, 더욱 상세하게는 용해로로부터 공급된 알루미늄 용융금속을 발포 알루미늄금속의 제조장치를 통과시켜 각종 규격의 발포 알루미늄금속판이나 발포 알루미늄금속봉 및 프로파일바등이 생산되도록 한 연속주조식 발포 알루미늄금속의 제조방법 및 그 장치에 관한 것이다.The present invention relates to a method for manufacturing a continuous cast foamed aluminum metal and its apparatus, and more particularly, to an aluminum molten metal supplied from a melting furnace through a foamed aluminum metal manufacturing apparatus through a foamed aluminum metal sheet or foamed aluminum metal rod of various specifications And it relates to a method and apparatus for producing a continuous cast foamed aluminum metal to produce a profile bar and the like.
일반적으로, 발포 알루미늄금속의 제조방법은 이미 널리 알려진 것으로 대한민국 특허출원 제 95-37839호에 개재되어 있으며, 이의 제조방법을 보면 원통상의 도가니에 알루미늄 용융금속을 주입한 후 교반하면서 증점제와 발포제를 순차적으로 가하여 균일하게 혼합되도록 교반하는 단계와, 상기 단계를 거친 혼합물을 가열수단이 구비된 주형에 낙하 주입하고 융점 이상의 온도로 유지하여 다수의 기포가 생성 성장하는 단계와, 상기 발포주형을 냉각시키는 단계 등으로 이루어진다.In general, a method for producing a foamed aluminum metal is widely known, and is disclosed in Korean Patent Application No. 95-37839. In the method for manufacturing the expanded aluminum metal, a thickening agent and a foaming agent are added while stirring after injecting molten metal into a cylindrical crucible. Adding and stirring the mixture so as to be uniformly mixed, and dropping the mixed mixture into a mold provided with heating means and maintaining the temperature at a melting point or higher, thereby generating and growing a plurality of bubbles, and cooling the foam mold. It consists of steps and the like.
이에 사용되어지는 발포 알루미늄금속의 제조장치는 도 1에 도시된 바와 같이 히터와 같은 가열수단(1)이 구비된 하부 주형(7)의 상측에 슬라이드 밸브(8)와 교반기(9)가 구비된 상부도가니(10)가 설치된 것이다.The apparatus for manufacturing foamed aluminum metal to be used is a slide valve (8) and agitator (9) provided on the upper side of the lower mold (7) provided with a heating means (1) such as a heater as shown in FIG. The upper crucible 10 is installed.
즉, 슬라이드 밸브(8)를 닫고 상부 도가니(10)의 내부에 알루미늄 용융금속을 주입한 다음, 교반기(9)를 작동하면서 증점제(공기, N2, CO2, H2O, 또는 Ar, Ca)를 투입하고, 일정시간이 지나 알루미늄 용융금속의 점도가 증대되면 발포제(TiH2, ZrH2등)를 투입하고, 발포제 확산교반이 끝나면 슬라이드 밸브(8)를 열어 균일혼합된 용탕을 적정온도로 가열된 하부 주형(7)에 낙하시켜 냉각하면 소망하는 발포 알루미늄금속괴가 형성되며, 이렇게 형성된 발포 알루미늄금속괴는 소정의 크기로 절단하여 출하된다.That is, the slide valve 8 is closed and aluminum molten metal is injected into the upper crucible 10, and then the thickener (air, N 2 , CO 2 , H 2 O, or Ar, Ca is operated while the stirrer 9 is operated. ), And when the viscosity of the molten aluminum is increased after a certain period of time, blowing agent (TiH 2 , ZrH 2, etc.) is added. Upon cooling by dropping the heated lower mold 7, a desired foamed aluminum metal mass is formed. The foamed aluminum metal mass thus formed is cut into a predetermined size and shipped.
그러나, 이와 같은 종래의 발포 알루미늄금속의 제조방법은 용융금속을 도가니에 주입한 후 알루미늄 용융금속을 교반하면서 증점제와 발포제를 동일 도가니에서 순차적으로 첨가하기 때문에 알루미늄 용융금속과의 혼합이 용이하지 않아 large hole 이나 불균일한 기포가 발생되는 문제점이 있었다.However, in the conventional method for producing expanded aluminum metal, the molten metal is injected into the crucible and then the thickener and the blowing agent are sequentially added in the same crucible while stirring the molten aluminum molten metal, so that the mixing with the molten aluminum metal is not easy. There was a problem that holes or non-uniform bubbles are generated.
또한, 종래의 발포 알루미늄금속의 제조장치로서는 발포 알루미늄금속괴만을 형성하기 때문에 상기 발포 알루미늄금속괴를 필요한 규격에 따라 다시 절단하므로서 그 작업이 극히 어려울 뿐만 아니라, 상기 발포 알루미늄금속괴를 절단할 때 발포 알루미늄금속괴의 가루가 많이 발생되므로서 발포 알루미늄금속의 생산효율이 극히 저하되는 동시에 손실이 크다는 등의 많은 문제점이 있었다.In addition, as a conventional apparatus for producing expanded aluminum metal, only foamed aluminum metal ingot is formed, and the work is extremely difficult by cutting the foamed aluminum metal mass again according to the required specification, and the foamed aluminum metal ingot is foamed when cutting. Since a lot of powder of the aluminum metal mass is generated, there are many problems such as the production efficiency of the foamed aluminum metal is extremely low and the loss is large.
본 발명은 상기한 제반 문제점을 해결하기 위한 것으로서, 증점 교반도가니에 알루미늄 용융금속을 주입한 후 상기 알루미늄 용융금속을 교반하면서 증점제를 첨가한 다음, 증점제와 혼합된 알루미늄 용융금속을 발포제 확산도가니에서 발포제를 첨가하여 교반시키므로서 발포 알루미늄금속에 균일한 기포가 생성되도록하여 발포 알루미늄금속의 품위를 크게 향상시킨 연속주조식 발포 알루미늄금속의 제조방법을 제공하는데 그 목적이 있다.The present invention is to solve the above problems, injecting aluminum molten metal into a thickening stirring crucible, and then adding a thickener while stirring the aluminum molten metal, the aluminum molten metal mixed with a thickening agent in a blowing agent diffusion crucible It is an object of the present invention to provide a method for producing a continuously cast foamed aluminum metal in which the uniformity of foamed aluminum metal is greatly improved by adding uniform agitation to the foamed aluminum metal.
본 발명은 또, 알루미늄 용융금속을 교반하면서 증점제를 첨가하는 증점제 교반도가니와, 증점제와 혼합된 알루미늄 용융금속에 발포제를 첨가하여 교반시키는 발포제 확산도가니를 별도로 설치한 다음, 상기 발포제 확산도가니로부터 공급된 발포 알루미늄 용융금속을 압출다이를 이용하여 소망하는 여러종류의 규격화된 발포 알루미늄금속을 생산하므로서 발포 알루미늄금속의 생산효율을 극대화시킴은 물론이고 발포 알루미늄금속의 제조비용을 크게 절감할 수 있는 연속주조식 발포 알루미늄금속의 제조장치를 제공하는데 그 목적이 있다.The present invention also provides a thickener stirring crucible for adding a thickener while stirring the molten aluminum molten metal and a foaming agent diffusion crucible for adding and stirring a blowing agent to the aluminum molten metal mixed with the thickener, and then supplied from the blowing agent diffusion crucible. By using extrusion die for foamed aluminum molten metal, it produces various kinds of standardized foamed aluminum metal, which maximizes the production efficiency of foamed aluminum metal, and can continuously reduce manufacturing cost of foamed aluminum metal. It is an object of the present invention to provide an apparatus for producing expanded aluminum metal.
