INTRODUCTION
Ferrochrome is used in the making of special types of steel, more extensively used for stainless steel is an alloy of iron and chromium. It is divided into two main types according to the carbon contents of the products i.e. High Carbon Ferrochrome (HCFC) and Low Carbon Ferrochrome (LCFC).
Chromium is added as ferrochrome in various types of steel to increase hardening, wire resistance to corrosion and stability at high operating temperatures. Its corrosion resistant properties become very much marked when the chromium content exceeds 12% in low carbon steels. Since addition of other elements such as nickel, increase resistance to non oxidizing acids, improves ductility and gives cold working properties. This is essential for the production of stainless steel and cast iron. Consumption of charge chrome or HCFC has been fairly successful although the demand for LCFC is going down not only in the country but also throughout the world.
The government of Orissa decided to establish IDCOL Ferrochrome and Alloys Ltd. (IFCAL) due to increasing demand of both HCFC and LCFC which was initially only imported. It is a unit of Industrial Development Corporation of India Ltd. (IDCOL) which is a state government undertaking working for the industrial development of the state. Previously ferrochrome was not produced in India, the materials were imported from foreign countries. IFCAL was the first response to the growing needs of the Indian economy. The license capacity of the plant is 10,000 M.T. LCFC and HCFC. Due to the low demand and high cost of production, production of LCFC was stopped. At present the plant produces only HCFC.
Every plant involves a number of components made to work in sync with each other. All the parts like the motors, generators, fuel oil controls, lubricating oil cooling chambers, charge air tubes, compressor air chambers etc. have to respond at the correct time one after he other as per the requirement of the plant.
