Indigenization of ALUMINIUM MOLYBDENUM TITANIUM master alloy production
There is a regular requirement of Aluminium Molybdenum Titanium master alloy alloy in steel making industries. Currently good quality of this master alloy is being imported. There is a need to have a reliable indigenous source for these master alloys. The specification of Al-Mo Ti master alloy alloy is given below.Aluminium : (Al) - Balance (40-44 %). Molybdenum : (Mo) - 48 - 52 %. Titanium : (Ti) - 6-9 %. Oxygen : (O) - 0.15 % max. Nitrogen : (N) - 0.05 % max. Phosphorous : (P) - 0.01 % max. Sulphur : (S) - 0.01 % max, Tungsten : (W) - 0.015 % max. Iron : (Fe) - 0.60 % max, Carbon : (C) - 0.10 % max. Silicon : (Si) - 0.50 % max. Boron : (B) - 0.005 % max. Magnesium : (Mg) - 0.25 % max. Chromium : (Cr) - 0.30 % max. Copper : (Cu) - 0.12 % max All other Element each : 0.10 % max.Size : - 10 mm max.
The percentage of fines in the alloy should be as low as possible.
PROCESS OF MANUFACTURE: The material shall be manufactured by Aluminothermic process followed by melting in vacuum induction melting furnace (double melting), or shall be manufactured by only Aluminothermic process, or shall be manufactured in Vacuum induction Melting furnace, but shall ensure the chemical composition as above. The equipment used for manufacturing, processing and inspecting the master alloys must be exclusively for making master alloys intended for Titanium alloy production. Any other novel method may also be used subject to meeting the requirements.
