3. Description:

The Electric Melting Furnace with compact design is ideal for professional use. By using high-quality materials, the smelting furnace can meet the requirements of the industry and the workshop, are suitable for the processing of precious metals such as gold,silver,pure copper,aluminum,Tin,Zinc and other metals with low acid-base property & not too high melting point.

The maximum adjustable temperature of our product is 1100° C(2012 ℉). Thus, the melting furnace is perfectly designed for the melting of precious metals. The melting point of silver is 962° C, gold is 1064 ° C. The regulation of the melting temperature is very user-friendly via a highly modern PID module. This module allows the digital adjustment of the setpoint temperature to the degree accurately. The PID module monitors the actual temperature in the melting chamber at 2-second intervals so that it does not overheat or cool down. The temperature is kept constant around the melting point.

4. Features:

【Large 3KG Capacity】1400W working power and 3KG large crucible capacity. It can smelt the precious metal fast.can be melted: 6KG gold,3.5KG sliver,3 KG copper,0.7KG aluminum.

【Professional Durable Materials】The product uses quartz furnace.The furnace wire seal integrated machine can be heated quickly. The inner tank is made of quartz and has the characteristics of heat resistance, acid and alkali resistance and aging resistance.

【PID Temperature Control Table】Equipped with advanced PID module and digital control system to provide accurate and convenient metal melting, monitoring the actual temperature in the melting chamber at 2 second intervals, so that it will not overheat or cool.

【High Purity Graphite Crucible】The high density of natural graphite makes the crucible have good thermal conductivity,temperature resistance,corrosion resistance and long service life.Specially the groove design acilitates the pouring and filling of the melt.

【Max Temp up to 1100 ° C/2012 ℉】The max heating temperature is up to 1100° C(2012 ℉). The melting furnace can melt metals with melting point below 1100 ° C such as: gold, sterling silver, pure copper and aluminum,Tin,Zinc,Brass Bronze etc.

Large 3KG Capacity

1400Wworking power and3KG large cruciblecapacity. It can smelt the precious metal fast.can be melted: 6KG gold,3.5KG sliver,3 KG copper,0.7KG aluminum.

Smelt Quickly

The melting furnace wire seal integrated machine can be heated and heated quickly. It can be fast heated up to 1100 °C/ 2000 °F. It takes 20-25 minutes to melt 3KG copper.

PID Temperature Control

Equipped with advanced PID module and digital control system to provide accurate and convenient metal melting, monitoring the actual temperature in the melting chamber at 2 second intervals, so that it will not overheat or cool., providing you precise and convenient metal melting. Durable Materials

Materials that have been tested to withstand high temperatures and extreme working conditions. The top of the furnace is made of quartz stone, which has heat resistance, acid and alkali resistance and aging resistance. This is your long-term partner.

Graphite Crucible

The high density of natural graphitemakes the crucible have good thermal conductivity,temperature resistance,corrosion resistance and long service life. Specially the groove design acilitates the pouring and filling of the melt.

High-purity

Graphite Ingot Mold

The mold is resistant to high temperatures and can withstand 2000 ℃.The brightness of the crucible is less than 0.1%, ensuring that the metal purity will not be affected during metal refining.

5. Technical Support：

1. The product work is under high temperature conditions, so it can't work for a long time, and it needs to be cooled for 3 hours.

2. When working, mainly protect yourself and avoid high temperature burns

3. The product can't work in humid environment

4. If the molten product contains substances such as acid and alkali, these substances will produce harmful gases with corrosion at high levels. In this case we recommend opening the furnace cover during the smelting process.

5. The maximum temperature of the product is 1100 °C. It is forofferden to smelt beyond this temperature.

6. Before use, check if the crucible is damaged. If it is damaged, replace it immediately.

7. In order to achieve the best results of smelting, do not fill the crucible. Gas is generated during the smelting process, and the metal is filled with metal, which causes an increase in pressure and poses a danger. If the armor is full, open the lid and smelt.

All Products from the factory will be provided for one year warranty after sales and lifetime technical support.

Questions & Answers

Q:What do I need to be aware of before I use it to melt metal?

A:Crucible needs to be dried when you first time to use it,the drying temperature keep 150-200℃ for about 30min, then it need take 5-6 minutes to preheat the crucible at 300 ℃ -500 ℃ before you put the metal into the furnace.

Q:Can this furnace melt brass and bronze?
A:Yes. It can.Since brass melting point is about 900-940 and bronze is about 850-1000 degrees C, then yes. It can melt copper, aluminum, gold, silver, brass,bronze,zinc,Tin and other metals with melting point below 1100 ℃/2012℉.

Q:I need to know if in the display the marked temperature is in ° F or in ° C ？
A:The temperature display is in °C

Q:What should I pay attention to when I melt aluminum?
A:It is easy to have a layer of alumina on the aluminum surface, and it needs to be sanded before it is arranged for melting.

Q:How long did it take to heat the unit and crucible to your desired temperature?
A:These furnaces take approximately 10-15 min to reach the desire temperature.

Q:Can we buy extra crucibles that we can use for different metals?
A:Yes, we can provide graphite crucibles capacity of 1KG,2KG and 3KG to meet your different requirements.Please click here to buy.
