Purpose. Smelting of ingots and slabs of titanium alloys of a wide range from commercially pure titanium to multicomponent high-strength and heat-resistant titanium alloys, alloys of the Ti-Ni, Ti-Al system, etc.
Specifications.
- Pilot plant power, kW 720
- Smelted ingot diameter mm 60—220
- Productivity, kg/h > 100
Application area. The technology can be used in the aerospace industry, mechanical engineering and instrument making.
Advantages. The new technology provides the following advantages: dense metal structure without pores, inclusions, shrinkage porosity and other defects; specified chemical composition of the alloy; the possibility of melting ingots of different cross sections; high quality of ingot surface formation; lack of selective evaporation of alloying components; the possibility of obtaining complexly alloyed alloys containing components with high vapor pressure (Cr, B, Mn, Sn, etc.).
Description. The process is carried out in a chamber-type electroslag furnace in an inert gas atmosphere at an overpressure of 0.1…1.0 at. Due to the impact on the metal bath by a magnetic field with an induction of 0.1 … 0.35 T, the ingot metal is mixed and homogenized.
