Development of Technology for Large Scale Production of Titanium Sponge

Intensive investigations on the development of titanium metal production technology had been carried out during 1965-1975 at the Bhabha Atomic Research Centre, Bombay and at the Nuclear Fuel Complex, Hyderabad. The Defence Metallurgical Research Laboratory, Hyderabad has set up a ‘Titanium Sponge Experimental Facility’ with a capacity to produce 100 tonnes of sponge per annum in 2000 kg batches by the Kroll’s process with a view to optimising technology for large scale production.The paper presents an outline of the experimental facility and discusses the various considerations that have gone into the design of equipment, materials of construction, process selection, etc. The facility has gone into operation in March,1985. The results obtained so far are encouraging
