Insulation World Company Limited is the leading supplier of High Carbon Silico Manganese (60/14) in the Kenyan Market and across the border. Our Ferro Silico Manganese contains high amount of both silico and manganese owing to which it finds applications in various industrial processes especially in the manufacturing of steel and iron as an oxidizing agent.
Silicon manganese is a chemical compound made by mixing natural silicon with manganese, an element found naturally in the earth. When combined, these elements can be used to produce a number of specialty steel alloys. Silico manganese enhances the natural properties of steel, giving it increased strength and function, as well as improved aesthetic appeal. This means that silicon manganese alloys can be used in applications beyond those associated with standard steel products. Silicon manganese may also be known as ferro silico manganese or abbreviated as SiMn.
Silico Manganese may be used alone, or combined with other substances to create various alloys. The ratio of silicon to manganese can also be adjusted to give steel the desired properties. Standard silicon manganese steel alloys contain 14 to 16 percent silicon, and as much as 68 percent manganese. They also include small amounts of carbon, which is required for the steel to undergo a chemical reactions with these compounds. In stainless or specialty steel products, the silicon content can be as high as 30 percent.
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. So, the process requires power consumption of about 3,800 to 4,800 kilowatt-hours per tonne.
