Introduction

Alloys and master alloys are made using ecologically clean technology of electric smelting in a crucible furnace "ICB-0,06" on the lines of advanced methods of melt cleaning by inert-gas blow prior to spillage.

Vacuum melting methods in service are widely used to produce broad range of materials which can not be made in any other way.

Procedure of vacuum re-melting is mostly oriented towards those procedures that are subject to environment decreased pressure, such as metallurgical reactions concerned with carbon, oxygen, nitrogen, and hydrogen.

Vacuum technologies are absolutely essential in producing alloys that due to their oxidation characteristics can only be produced in the vacuum or inert atmosphere. Controlled atmosphere limits oxide non-metallic inclusions in the melt.

Vacuum melting with induction heating has the following advantages:

1. Possibility of prolonged keeping of liquid metal in high vacuum.
2. High level of degassing.
3. Possibility to execute initial filling of the furnace during the process of melting; to intensify the process of de-oxidation and refining at any moment of melting.
4. Ability to effectively control and regulate the melt condition by its temperature and chemistry within the procedure.
5. Particular purity of casting due to the absence of any non-metallic inclusions.
6. Possibility to execute flash-heating (direct heating by means of heat released during the melting); and therefore high speed of melting and high capacity.
7. High homogeneity of the melt due to the dynamic stirring of the metal.
8. Optional primary products form (bulk material, bricks, powder form, etc).
9. High economy and ecological cleanness.

The above is particularly significant regarding the application of the new materials in the high-tech fields of science and engineering such as aerospace, aircraft and car industries. Extra strength and safety of these materials will add new features to the produced equipment.
