Melting furnace

The metals are usually melted in graphite crucibles in a melting furnace, also called a crucible furnace.

We generally differentiate between:

- Propane gas-powered furnace

- Electrically powered furnace

Thermal security

00159051

consisting of thermal security valve in and thermal sensor and capillary tube, ca. 750 mm length of the capillary tube. Gas-entry M 14x1,5 AG (for cutting ring fitting Ø 8 mm), Gas-outlet M 14x1,5 IG (cutting ring fitting Ø 8 mm) Suitable for Proforge, P-301 and P-302, and other gas forge furnaces. The thermal monitoring device is part of the thermoelectric ignition safety device for gas-fired forge furnaces and, in the event of a malfunction, is designed to quickly prevent the escape of unburned gas. Function: The gas flame heats the tip of the thermocouple. This generates a thermal voltage, which is conducted through the copper wire to a holding magnet. Once sufficient voltage has been built up, the magnet holds the valve open. If combustion ceases, the tip of the thermocouple cools down, the thermal voltage is reduced, and the holding magnet closes the valve. The response time is between 10 and 60 seconds, depending on the design. An essential safety device for all gas-fired forge furnaces. Also suitable for DIY construction!

What is a melting furnace?

In a melting furnace, the material is melted using a crucible.
The furnace is also called a crucible furnace.

What types of melting furnace are there?

We have different types of melting furnaces:
- Propane gas powered melting or crucible furnaces
-Electric powered furnaces
It can also be melted using an induction device.
Similarly, the coal furnace or gas furnace can be used for casting

Buy a melting furnace or crucible furnace?

We have various furnaces in our range.
We would be happy to advise you on what is suitable for your project or application.

Which melting or crucible furnace is better?

Gas, electric, induction, or?
There is no direct answer here.
We would be happy to advise you on what is suitable for your project or application.

Melting or crucible furnace for small projects?

We recommend an electric furnace here?
This is easy and safe to use and is quickly ready for use.
This type of furnace is also well suited for school lessons or projects with children.
We would be happy to advise you on what is suitable for your project or application.

What should you look for when buying a melting or crucible furnace?

Here we recommend a furnace that has been tested and not a Chinese product!
Vevor, Aliexpress and whatever they are called offer devices with a CE mark.
However, these devices do not have a real CE mark, but the "CE" stands more for "Chinese export".
The devices work but are catastrophic in terms of safety.
In the event of damage, no manufacturer accepts responsibility for these devices.
It is therefore important to go for tested and reputable manufacturers when buying.
