Mini metal melting furnace

    The mini metal melting furnace is small in size, simple and convenient to operate, and can smelt a large number of samples. Therefore, it is an ideal equipment for preparing metal and alloy samples in universities and research institutes.

(Non-self-consuming) mini metal melting furnace is a small high vacuum arc melting furnace, which is equipped with a visual vacuum pressure gauge to directly observe the vacuum degree in the chamber. The alloy ingot can be turned for multiple melting without destroying the protective atmosphere of the gas, and up to 7 samples can be prepared at the same time. The mini metal melting furnace is small in size, simple and convenient to operate, and can smelt a large number of samples. Therefore, it is an ideal equipment for preparing metal and alloy samples in universities and research institutes. It can be used for the preparation, purification and mixing of new alloy materials, such as high entropy alloy and high temperature alloy. Mini metal melting furnace uses tungsten needles as electrodes. The melting point of tungsten is extremely high, and the arc temperature can reach 4000℃, which can melt almost all metals. When the furnace is working, the electrodes and crucibles should be cooled with circulating water to ensure that the electrodes and crucibles will not be melted.

Specifications of Mini metal melting furnace:

Product model

CY-MSM20-7 (Non-consumable) Mini metal melting furnace

Installation conditions

This equipment is required to be used at an altitude below 1000m, temperature 25℃ ± 15℃, humidity 55% Rh ±10% Rh.

1. Water: The equipment is equipped with a self-circulating cooling water machine (filled with pure water or deionized water)

2. Power: AC380V 50Hz (63A air switch), must be well grounded

3. Gas: The equipment chamber needs to be filled with argon gas (purity above 99.99%), and an argon gas bottle must be prepared by yourself (with Ø6mm double card sleeve connector)
