Problems solved by technology

[0004] However, this kind of supply device and method is carried out in an open space. Therefore, the heat energy of the molten metal raw material 12 will continue to dissipate into the open space, causing its temperature to drop rapidly and oxidation reactions to occur, resulting in a casting operation. Defects occur, which greatly reduces the casting yield
In addition, because the heat energy of the molten metal raw material 12 continues to dissipate into the open space, it is difficult to maintain the melting temperature, and it must be heated frequently to maintain the molten state, so it consumes a lot of power

Embodiment Construction

[0041] The present invention is described in detail below in conjunction with accompanying drawing and embodiment:

[0042] refer to figure 2 , a preferred embodiment of the method for supplying molten aluminum alloy in the present invention comprises the following steps:

[0043] Step 21: Construct a closed space with an outlet, and divide the closed space into a melting chamber and a preheating chamber connected to each other, and the preheating chamber is located above the melting chamber.

[0044] Step 22: Preheating the solid aluminum alloy in the preheating chamber to remove hydrogen, oxygen and moisture in the solid aluminum alloy. In this preferred embodiment, the solid aluminum alloy is aluminum grains of aluminum alloys, but it can also be other smaller volumes of aluminum alloys, such as aluminum shavings of aluminum alloys. The temperature in the preheating chamber is about 450°C to 550°C. The heat energy comes from the high heat generated in the melting chamber...

Abstract

The invention provides a method and an apparatus for providing aluminum alloy meltwater. The method comprises the steps of building a sealing space with an outlet and dividing the sealing space into a melting chamber and a preheating chamber, which are mutually communicated; feeding solid aluminum alloy to the preheating chamber for preheating and removing hydrogen, oxygen and steam from the solid aluminum alloy; transmitting the preheated solid aluminum alloy to the melting chamber and heating the preheated solid aluminum alloy into aluminum alloy meltwater; taking out the aluminum alloy meltwater from the sealing space by means of a soup spoon. Accordingly, the solid aluminum alloy is melted into the aluminum alloy meltwater in the sealing space, heat energy dissipation can be effectively reduced, and the aim of saving power can be achieved, and the casting yield can be improved.

Description

technical field [0001] The invention relates to a method and device for supplying molten metal, in particular to a method and device for supplying molten aluminum alloy. Background technique [0002] Casting is a metal processing method that first heats and melts metal into a liquid metal melt, and then pours the metal melt into a casting mold of a specific shape and waits for it to solidify and form. Because the temperature of the molten metal is very high, it needs to be filled with a high-temperature resistant metal and ceramic spoon, and the molten metal in the spoon is moved to the gate of a casting mold by a mechanical arm Poured and shaped through casting moulds. [0003] refer to figure 1 Taking the liquid raw material supply device, liquid raw material supply method, and scoop of the die-casting machine of China Taiwan Invention Patent Certificate No. I280166 as examples, the liquid raw material supply device of the die-casting machine includes a scoop 10 and a co...
