Any emergency action, however, would require considerable coordination of facilities and time for conversion. Unlike pigment production that uses considerable domestic ore sources, the United States imports, most if not all, of the ore used for domestic titanium metal production.

From page 88... ...
A detailed breakdown of the amounts and the location of the domestic source were not available to the panel. Another company that has a very large capacity to produce titanium tetrachloride and that achieves considerable ore production from domestic mines does not supply titanium tetrachloride to the metal producers.

Titanium Sponge The domestic production of sponge titanium was studied at length. Immediately prior to the NMAB study -- and continuing during the early part of its investigation -- a sponge shortage resulted from inadequate (albeit probably caused by an "art if icial" shortage due to panic buying and double ordering ~ domestic sponge production capacity .

S . vacuum-dis t tiled sponge plus the currently planned production of vacuum-distilled sponge by a company now constructing facilities, and a further expansion of domestic electrolytic sponge titanium production should alleviate the problem to some extent, perhaps totally.

~ Thus, triple melting for premium-quality ingots remains as a requirement and as a bottleneck in terms of reducing melting capacity f rom what it would be without this requirement. There is a lack of adequate personnel who have sufficient background in melting operations to permit capacity expansion of ingot production.

Bloom Forging Bottlenecks in this operation are related to inadequate soaking furnace capacity, inadequate press capacity, and inadequate manipulators. As important as these equipment def iciencies is the inadequate number of professionally trained personnel who are trained to monitor metallurgically the breakdown forging operation and to operate the f orging equipment .

Other semi-products also are rolled in steel mill equipment on a toll basis. For example, hot band is produced on Steckel mills as precursor material for hand-mill sheet product in some company operations.
|
From page 94... ...
Hence, because of scheduling difficulties, the toll rolling of strip may be considered to be a bottleneck. The hand-mill pack rolling of titanium alloy sheet products may be considered a technological bottleneck, albeit that the hand-mill processing of thin plates to sheet gauges in packs (within steel envelopes)

For example, castings for critical components require 100 percent inspection. Further, castings from some manufacturers require extensive weld repair.

For titanium mill processing, the sword may be tonnage powder metallurgy (TPM) , not for complex powder metallurgical shapes weighing ounces or pounds but for mill products weighing tons.

From page 97... ...
Insufficient numbers and sizes of melt furnaces are bott lenecks . The necessity for triple melting some ingots to meet special specifications is a bottleneck.
|
From page 98... ...
A shortage of personnel properly trained f or conducting and monitoring def ormation operations is a bottleneck. Furnacing and handling equipment and personnel inadequacies may be considered as bottlenecks for selec ted operas ions .

From page 99... ...
Specialty Products Production was not studied; bottlenecks unknown. General The custom-job-shop nature of the titanium metal industry may be considered as a bottleneck to the more ef f icient production of ti tanium product s .
