Ferroalloy ABC: Manufacturing cost is formed

Ferroalloy basically uses electric stove production, power consumption is tall, need is rich and the power natural resources of valence cheap. France becomes the main production state of inchoate ferroalloy, 20 centuries 80, 90 time Norway becomes the biggest ferroalloy to export a nation, it is the resource of water and electricity that abounds with place is development base.

The production of ferroalloy is high cost can process, the sources of energy is occupied in the cost structure of ferroalloy bigger. In light of the main breed manganese with respect to ferroalloy, chromic, silicon, besides silica home resourceful, the price is low outside, manganese mine because domestic grade cost of inferior, exploitation is higher and the element such as reserve, about 1/3 manganese mine needs an import, the proportion that manganese mine produces cost in manganese alloy is larger; Natural resources of our country chromic ore is exceeding lack, count an import basically entirely, the proportion that chromic mine holds in ferrochrome cost structure is larger.

The manufacturing cost of ferromanganese alloy basically is mixed by manganese mine stone, electric power of coke purchase cost to form, among them charge of manganese mine stone is occupied about 60% , charge of electricity is occupied about 20% , 25% , coke charge is occupied about 10% , 15% . Additional, when a lot of enterprises are producing ferromanganese alloy, besides the manganese mine stone that uses homebred low phosphor, low iron, low sulfur, low silicon, the grade entering furnace that expects to carry highland, increase manganese element to reclaim rate, reduce power consumption and manufacturing cost, smelt undertakes after the part is being bought to import mine and homebred mine to deserve to compare outside need. The wave motion because of price of stone of this manganese mine, charge of electricity and coke price produces the effect with larger generation to ferromanganese alloy.

As similar as ferromanganese alloy, chromic mine also holds larger proportion in the manufacturing cost of ferrochrome. Natural resources of our country chromic ore is very few, wastage of chromic 2013 mine is close 14 million tons, domestic supply is controlled for 2 million tons only, the others all relies on an entrance to solve. Chromic ore charge is occupied about in cost of production of our country ferrochrome 60% , charge of electricity is occupied about 25% , 30% , coke charge is occupied about 10% , 15% .

Because silica is low-cost, specific power consumption produces medium proportion in ferrosilicon the biggest. Produce raw material of a ton of ferrosilicon and electric energy to use up for: Silica 1780, 1850 kilogram, coke 890, 930 kilogram, steel bits 220, 230 kilogram, electrode is burnt 45, 55 kilogram, power consumption 8400, 9000kWh/t. In the cost of ferrosilicon, electric power was occupied 70% the left and right sides.
