What does molten metal look like in space?

Not so long ago, a space melter was delivered to the ISS - a device for melting a small amount of metals in zero gravity. Of course, there are no and cannot be any blast furnaces and similar units on the ISS, the device for smelting is as high-tech as everything else at the station.

Developed "smelter" by the specialists of the European Space Agency. It is equipped not only with the node responsible for smelting metal, but also with the “levitator” - the system that is responsible for keeping the ball of molten metal in one place.

That is why astronauts do without walls for this installation. The smelter itself (someone else called the forge) is used to study the properties of molten metals in zero gravity. The cooled metal will be studied, since its structure under these conditions will be slightly different than on Earth.

In the future, the ISS will carry out the creation of various alloys, with the fixation of the process of melting and cooling with a high-speed camera.
