Ferroalloy Production Cost Structure

The main ferroalloy electric furnace production, high power consumption, requires abundant and inexpensive power resources. France became a major producer of ferroalloys in the early 20th century 80--90 become Norway's largest exporter of iron alloy, are based on local rich hydropower resources for the development of the foundation.
Ferroalloy production is energy-intensive process, a larger proportion of energy in the cost structure of the alloy. On the main varieties of ferroalloy manganese, chromium, silicon, in addition to silica-rich domestic resources, low prices, lower domestic manganese ore grade, higher mining costs and reserves and other factors, the need to import about a third of manganese ore, manganese ore in the proportion of manganese alloy production costs greater; extreme lack of chrome ore resources, all the basic dependence on imports, a large chrome ferrochrome mine in the proportion of the cost structure.
The main cost of production of manganese ferroalloys, coke and electricity procurement costs consists of manganese ore, manganese ore which cost about 60%, about 20% -25% electricity, coke costs about 10% -15%. In addition, many enterprises in the production of ferro-manganese, in addition to the use of domestic low phosphorus, low iron, low sulfur, low silicon manganese ore outside, in order to improve the quality of the raw material into the furnace to increase the recovery rate of manganese, reduce power consumption and production cost, need to outsource some of the imported and domestic ore mine after the ratio of smelting. Therefore, the price of manganese ore, electricity and fluctuations in the price of coke for the production of manganese ferroalloys have a greater impact.
Similar manganese alloys, chrome ore ferrochrome production costs also account for a large proportion. Few of chrome ore resources, in 2013 nearly 14 million tons of chrome ore consumption, domestic supply is only 200 million tons, the rest by imports. Our chrome ore production cost ferrochrome costs about 60%, about 25% -30% electricity, coke costs about 10% -15%.
Since silica cheap prices, the proportion of energy consumption in the production of ferrosilicon maximum. Ferrosilicon production of one ton of raw materials and energy consumption: silica 1780-1850 kg coke 890-930 kg 220-230 kg of steel scrap, the electrode paste 45-55 kg, power consumption 8400-9000kWh / t. Ferrosilicon in cost, electricity accounted for about 70%.
