History of Titanium

Dr. Kroll visited our Titanium Laboratory to see our vacuum-type high-frequency melting furnace during testing. (1953)

A 50kg titanium ingot melted once (longer ingot on left), and ingot melted twice (shorter ingot on right) using the consumable electrode vacuum arc melting process that was developed with the technical support of Dr. Kroll and Mr. Gilbert, Engineer. (1954)
Kobe Steel succeeded in the manufacture of an ingot with a good, complete surface and exported a sample to the U.S.A. for the first time in 1955.

A 1-ton VAR melting furnace installed at the time the Titanium Melting Plant was constructed. (1959)

A 1-ton twice-melted titanium ingot being discharged from the vacuum arc melting furnace. The furnace was our original design, and began initial operation in our Takasago Plant in 1959. The completion of this furnace initiated extensive use of titanium products in the chemical industry.
