INTRODUCTION Bulk Ferro Alloys such as ferro manganese ferro silicon and silico manga-nese are required for deoxidation and alloying of steel. Demand of the ferro alloys are likely to go up in keeping with the rising trend of consumption and production of steel in India.
Introduction. Silico manganese is an alloy with 60 to 68 manganese 14 to 21 silicon and 5 to 2.5 carbon. It is produced by smelting of slag from high-carbon Ferro Manganese or of Manganese ore with coke and a quartz flux in a submerged electric arc furnace. The process requires power consumption of about 3800 to 4800 kilowatt-hours per tonne.
Jun 19 2018 Production of Ferro- Manganese. Ferro-manganese Fe-Mn is an important additive used as a deoxidizer in the production of steel. It is a master alloy of iron Fe and manganese Mn with a minimum Mn content of 65 and maximum Mn content of 95 .
Manganese Ferro Alloys are mainly manufactured by carbothermic reduction of manganese ores containing both iron and manganese oxides in submerged arc electric furnaces. The slags produced during the process contain significant amounts of manganese oxide. 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
Sep 24 2012 High quality briquettes can be produced by mixing the resin bindercompaction and by curing at 150˚ C temperature. The process flow sheet developedfor briquetting is shown in Figure-10. The developed product was tested in the laband commercialized after successful plant trials. Tata Steel produces 25kTPA highcarbon ferro manganese fines.
In this process HC FeMn alloy ~7 C 1 Si is decarburized by blowing the metal in its liquid state with oxygen gas or with oxygen-argon mixtures. This manganese oxygen refining MOR process is in many ways similar to the basic oxygen steel process BOF where liquid cast iron is decarburized by blowing with oxygen in a converter.
Ferro manganese is the most important ferro alloy used in steel industry and its consumption in the world exceeds all other ferro alloys com-bined. In India approx. 15 to 16 kg of ferro manganese is consumed for every tonne of steel produced as against around 6 kg of standard grade ferro manganese consumed in industrially advanced countries.
The primary objective of the study is to review the technological status of ferroalloys industry in the country in the area of bulk production of silicon. Bulk ferro alloys include ferro manganese ferrosilicon etc. Manganese is used in metallurgic

The complete design process from start to end is often outlined as shown in Figure 4.1. Figure 4.1 Flow chart of mechanical design. The process begins with recognition of a need and a decision to do something to meet the need and after many iterations ends with the presentation of the plans for satisfying the need.
Boron deficiency is a cause of concern in highly calcareous soils of Bihar parts of Gujrat and Tamilnadu. Application of 10kg Borax ha or spray of 0.2 Boric Acid is recommended to address the nutritional problem pertaining to boron. Manganese deficiency is mainly reported from Punjab where it has become a major threat for wheat productivity.
