Tungsten and tin selection equipment jig

The tungsten tin selection equipment jig is a key equipment used in the preparation process of tungsten tin alloys. In the process of preparing tungsten tin alloy, impurities need to be separated from the alloy, and this step requires the use of a jig. This article will introduce the working principle, operating steps, and precautions of the tungsten tin selection equipment jig.

1、 Working principle

Tungsten tin separation equipment jig is a kind of equipment based on gravity Separation principle. In the jig, the melt of tungsten tin alloy passes through an inclined metal plate, and the holes on the plate allow the melt to flow through, while impurities are blocked on the plate. Due to the lower density of impurities compared to tungsten tin alloys, impurities will deposit on the plate, while pure tungsten tin alloys will flow through the plate holes and eventually be collected.

2、 Operating Steps

1. Preparation work

Before operating the jig, it is necessary to prepare the necessary equipment and materials. These equipment include jigs, furnaces, shovels, sieves, etc. Materials include tungsten tin alloy, flux, etc.

2. Heating furnace

Heat the furnace to the required temperature. Usually, the melting point of tungsten tin alloy is around 2600 ℃, so it is necessary to heat the furnace to above 3000 ℃.

3. Add flux

Adding flux to the furnace reduces the melting point of tungsten tin alloy, making it easier to melt. Normally, the amount of flux used is about 10% of that of tungsten tin alloy.

4. Add tungsten tin alloy

Add tungsten tin alloy to the furnace, wait for it to completely melt, and then pour the melt into the jig.

5. Separation of impurities

When the melt flows through the jig, impurities will be blocked on the plate, and pure tungsten tin alloy will flow through the plate hole and eventually be collected.

6. Collect tungsten tin alloy

Pour the collected tungsten tin alloy into the mold and let it cool and solidify to obtain a pure tungsten tin alloy.

3、 Precautions

1. It is necessary to wear protective gloves and goggles during operation to prevent injury caused by molten metal splashing.

2. During the process of adding tungsten tin alloy and flux, it is necessary to pay attention to safety and avoid damage caused by molten metal splashing.

During the operation of the jig, it is necessary to keep the jig clean to avoid the impact of impurities on the separation effect.

When collecting tungsten tin alloys, it is necessary to pay attention to the temperature of the mold to avoid chemical reactions caused by prolonged contact between the molten metal and the mold.

In short, the tungsten tin selection equipment jig is an indispensable equipment in the preparation process of tungsten tin alloys. When using a jig, it is necessary to pay attention to safety, follow operating procedures, and keep the equipment clean in order to obtain high-quality tungsten tin alloy.
