The advantages of the molten gold machine - the use of the Hairuituo melting machine

Everyone can often see jewelry processing shops on the street. When processing gold jewelry, it will definitely use a gold melting machine, such as a high-frequency melting machine, which is the most commonly used one. Let me talk about how to use the molten gold machine, what are the advantages of high temperature high frequency melting machine?


How to use the gold melting machine

1. The process of smelting, purifying, casting, etc. is mainly carried out by means of a enamel container for instant induction of precious metals. For precious metals: platinum, palladium, gold, gold, silver, copper, steel, gold powder, sand, tin ash, tin High melting gold metal such as slag. The fastest heating speed is less than 1 second (the speed can be adjusted).

8, the heating is very uniform (can adjust the density of the induction coil, so that each part of the work to obtain the required temperature), heating up quickly, less oxide layer, no waste after annealing. Eliminating the high voltage eliminates the transformer that produces nearly 10,000 volts of high voltage, which is very safe.

2. The molten gold machine adopts 200~2500Hz intermediate frequency power supply for induction heating, the power range is 15~160KW, and the melting amount is 4~75KG, which is specially used for melting gold. The gold melting machine can also purify the gold. After the slag powder is placed in the melting machine, the impurities are removed after passing through the high temperature in the furnace. In addition to slag powder is also called borax, all chemical stores have sales, the price is about 10 yuan / 500 grams.





The basic composition of high frequency melting machine
·Including high frequency power supply (one machine or split machine), induction coil, 坩埚


High-frequency melting machine can use 220V voltage energy saving and environmental protection
Medium frequency melting gold furnace adopts 380V three-phase electricity. It can be changed to three-phase four-wire five-wire system.

The high temperature melting machine can reach a temperature of more than 1800 degrees. Suitable for gold k gold silver smelting
The maximum temperature of the medium frequency melting furnace can reach more than 2800 degrees. Suitable for platinum, palladium, gold smelting



High frequency melting machine advantages

1. The molten gold machine is small in size, light in weight, high in efficiency and low in power consumption;

2. The temperature around the furnace is low, the smoke is less, and the working environment is good;

3. Simple operation process and reliable smelting operation;

4. The heating temperature is uniform, the burning loss is small, and the metal composition is uniform;

5. The casting quality is good, the melting temperature is fast, the furnace temperature is easy to control, and the production efficiency is high;

6. The utilization rate of the molten gold machine is high and the replacement is convenient.

7. The melting machine is equipped with a 50kw air-cooling cabinet, compensation capacitor and furnace body.



Induction heating melting and traditional flame heating melting comparison

Compared with the traditional flame melting process, induction heating melting has obvious advantages such as energy saving, environmental protection and safety.
