Henry Bessemer invented the use of ferromanganese as a method of introducing manganese in controlled proportions during the production of steel.
12.
At the outbreak of World War II, however, the Tennessee Products Corporation reopened the iron works to produce ferromanganese for the wartime effort.
13.
Likewise, the ferromanganese melts and is combined into the pool of liquid iron in the'well'at the bottom of the cupola.
14.
In 1965, new ferromanganese factory was opened in privatised, eventually leading to its transformation to OFZ, a . s ., Istebn?
15.
This method saved a large amount of ferromanganese, since when steel is deoxidized in the furnace of about 50 % of it oxidized and was lost with the slag.
16.
Adding a certain amount of ferromanganese to the coating makes it possible to compensate for the manganese that is lost through oxidation during welding and to deoxidize the weld pool.
17.
Additions to the molten iron such as ferromanganese, ferrosilicon, Silicon carbide and other alloying agents are used to alter the molten iron to conform to the needs of the castings at hand.
18.
Plant capacity is over 1 million metric tonnes of silicomanganese and 250, 000 tonnes of high carbon ferromanganese, along with significant production capabilities in materials required for manganese production ( fluxes ).
19.
For other metals, Matignon showed that technical-grade zinc, aluminium and ferromanganese powders always contain some nitrogen ( e . g . 0.2 % 0.4 % for zinc ).
20.
Orissa : 276 large and medium industries are in operation ( 1993-94 ), mostly based on minerals, steel, pig iron, ferrochrome, ferromanganese, ferrosilicon, aluminium, cement, automotive tyres and synthetic fibres.
