Manganese Oxide MnO and these slags can be reprocessed to Ferro Silico Manganese popularly called Silico Manganese and then to refined or Low-carbon LC – Fe Mn Ferro Manganese or even to Manganese metal. High-carbon Ferro Manganese generally with 70–80% Mn and 6–8% C is a deoxidizing agent in steel making and an important alloying
If silico manganese slag is used less fuel is required to be burned resulting in reduced emissions and a saving in carbon taxes. - The other is the C0 2 removed from limestone. As part of the C0 2 producing limestone has been replaced with precalcined silico manganese less C0 2 is produced here as well offering a further reduction in Carbon ImagesMore results in images
Silico Manganese is generally made in two grades containing 60–65% Manganese Mn but with ideally either 14–15% Si or 15–19% Si. These Ferro alloys are preferred by steelmakers who require to add manganese and silicon simultaneously for deoxidation purposes. Silico-Manganese is used either as a substitute for ferro manganese and ferro silicon in steel making or as a material for
High C Fe-Mn can be made in BF and in SAF. In SAF it is made by two different practices namely i high Mn slag practice and ii discard slag practice. Medium C Fe-Mn can be produced by a de-carbonation process or through a redox reduction-oxidation reaction between silicon Si in the silico-manganese Si-Mn alloy and Mn ores.
There are two families of Mn alloys called ferro-manganese FeMn and silico-manganese SiMn . Silico-manganese adds additional silicon which is a stronger deoxidizer and which also helps to improve some mechanical properties of steel. In each family carbon is controlled and is lowered when producing ‘‘refined’’ grades.
The economics of silicomanganese smelting is enhanced by minimising the loss of manganese as metal inclusions as MnO dissolved in the slag and by production of metal high in silicon and low in carbon.
Silico Manganese is an alloy with 65% to 68% manganese 16% to 21% silicon and 1.5% to 2% carbon. It is produced by smelting of slag from high-carbon Ferro Manganese or of Manganese ore with coke and a quartz flux. Smelting temperatures are high and greater energy is needed to reduce the quartz to silicon.
The slag comprises of granules of silico manganese denuded ore and the as an ingredient and concrete production as a cementitious reactive aggregate.
