Description

마그네슘 용탕 공급장치Magnesium Molten Feeder

본 발명은 마그네슘 용탕 공급장치에 관한 것으로서, 보다 구체적으로는 마그네슘 용탕액이 공기중의 산소와 질소및 수분등과 반응하여 연소하는 것을 방지함과 동시에 열 손실없이 금형에 공급하여 성형할수 있게한 것이다.The present invention relates to a magnesium molten metal supplying device, and more specifically, to prevent the magnesium molten liquid from burning by reacting with oxygen, nitrogen, and moisture in the air, and to supply the mold with no heat loss. .

일반적으로 마그네슘은 용융점과 밀도가 낮고 가벼운 재료로서 특히 알칼리성 물질에 안정적인 특징이 있고 용융상태에서는 산소 또는 질소와 반응하여 연소하고 특히 수분과 접촉케 되면 폭발적 연소를 하게되어 용융로 내에서 마그네슘 용탕액과 공기를 접촉하지 못하게 하여야함으로 고가의 SF6 가스를 용해로 내에 투입하여서 용탕액의 연소를 방지하였고 응고잠열이 적기 때문에 급속히 응고됨으로 마그네슘 용탕액 상태로 금형에 이송이 어렵고 응고시간이 빨라 대형의 마그네슘 제품을 만들기가 어려운 결점이 있었다.In general, magnesium has a low melting point and low density and is a light material. It is particularly stable in alkaline substances, and in a molten state, it reacts with oxygen or nitrogen to burn, and when it comes into contact with moisture, it explodes into combustion, and thus, magnesium molten liquid and air in the melting furnace. It is necessary to prevent the contact of high-priced SF6 gas into the melting furnace to prevent the burning of the molten liquid and to solidify rapidly due to the low latent heat of solidification. There was a difficult flaw.

본 발명은 상기와 같은 종래의 결점을 개선하여 마그네슘 용탕액과 공기의 접촉을 차단함과 동시에 마그네슘 용탕액을 금형에 공급하고 용탕액은 가압하여 제품을 성형할수 있게 한 것으로 이를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is to improve the above-mentioned drawbacks to block the contact between the magnesium molten liquid and air and at the same time to supply the magnesium molten liquid to the mold and to pressurize the molten liquid to form a product based on the accompanying drawings When described in detail as follows.

도 1은 본 발명의 실시예를 나타낸 단면도이다.1 is a cross-sectional view showing an embodiment of the present invention.

Air blocking valve 204 is formed in the nozzle part of the supply pipe 201 which communicates with the supply cylinder 2 which forms the gas layer 6 between the air and the supply piston 203 and the adjusting screw on one side of the supply piston 203. It is a structure which is installed outside the melting furnace 1, the electric heater 202 is provided in the outer periphery, and the pressure cylinder 3 is attached to the pouring port 401 of a metal mold | die.

미설명 부호 101은 가스주입밸브이다.Reference numeral 101 is a gas injection valve.

이와같이된 본 발명은 용해로(1) 내에 아르곤 가스층(6)이 형성되어 마그네슘 용탕액(5)과 공기의 접촉을 막아서 연소를 방지케 되고 공급피스톤(203)의 조절나사(205)를 회전하여 용탕액의 공급량을 조절할수 있으며 공급관(201)의 노즐부에 공기차단밸브(204)가 장치되어 용탕액의 공급시에만 열리게하여 공기가 용해로 내로 유입되는 것을 방지하고 공급실린더(2) 내에 투입된 용탕액(5)이 공급피스턴(203) 가압에 의해 히터(202)가 예열된 공급관(201)을 통해 용융상태로 가압실린더(3) 내에 투입되고 가압피스턴(301)이 작동하여 가압실린더(3) 내의 용탕액(5)을 금형(4)의 내측 성형홈으로 공급케 되어 마그네슘 제품을 생산할수 있는 것이다.In the present invention as described above, the argon gas layer 6 is formed in the melting furnace 1 to prevent the contact between the magnesium molten liquid 5 and the air to prevent combustion and to rotate the adjustment screw 205 of the supply piston 203. The supply amount of the melted liquid can be adjusted, and an air shutoff valve 204 is provided at the nozzle portion of the supply pipe 201 to open only when the melted liquid is supplied, thereby preventing the air from flowing into the melting furnace and introducing the melted liquid into the supply cylinder 2. (5) The feed piston 203 is introduced into the pressurized cylinder 3 in a molten state through the supply pipe 201 preheated by the heater 202, and the pressurized piston 301 is operated to operate in the pressurized cylinder 3. The molten liquid 5 is supplied to the inner molding groove of the mold 4 to produce a magnesium product.

상기와 같이된 본 발명은 용해로(1) 내에 용탕액(5)이 채워지면 용탕액 상층과 공기층 사이에 아르곤 가스층(6)이 형성되어 용탕액(5)이 공기와 분리되어 연소반응을 방지할수 있고 이송관 표면에 전기히터(202)를 장치하므로서 용탕액이 응고되기 전에 금형에 공급하여 가압실린더를 통해 가압할수 있게되므로 마그네슘제품을 압착성형방법으로 제작할수 있는 것이다.In the present invention as described above, when the molten liquid 5 is filled in the melting furnace 1, an argon gas layer 6 is formed between the upper liquid layer and the air layer, so that the molten liquid 5 is separated from the air to prevent combustion reaction. And by installing the electric heater 202 on the surface of the conveying pipe can be supplied to the mold before the molten liquid is solidified and pressurized through the pressure cylinder can be manufactured by the compression molding method of magnesium products.
