High Carbon Ferrosilicon

Description

High Carbon Ferrosilicon is a common metallurgical material with 75% silicon content, which is a common raw material used in steel making. The raw materials are mainly coke, steel chips and quartzite, which are produced by heating and smelting in electric furnaces.

Ferro silicon is an important alloy, which can remove oxygen from the steel in iron and steel production and increase the final quality of the steel. Ferrosilicon is also the basis of pre-alloys for the manufacture such as fesimg for the modification ofmelted malleable cast irons. Ferrosilicon is a type of alloy, silver-gray, with blocky, spherical, granular and powdery shapes. In the steelmaking industry, about 3-5kg of 75% ferrosilicon is consumed to produce one ton of steel.

Features

1.High Carbon Ferrosilicon is widely used as deoxidizer and alloy additive in steelmaking.

2.Ferro silicon powder emits a lot of heat in steel making production, and is used as a heating agent for steel ingot caps to improve the recovery rate and quality of steel ingots.

3.Ferrosilicon can be used as inoculant and nodulizer for cast iron.

4.High silicon content ferrosilicon alloy is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry.

5.Ferrosilicon powder or atomized ferrosilicon powder can be used as coating for welding rod production.

6.Ferrosilicon can be used for high-temperature smelting of magnesium metal. 1 ton of metallic magnesium needs to consume about 1.2 tons of ferrosilicon.

Performance

1. Reducing chilling tendency significantly and relative hardness, improve machinability.

2. High anti-decline ability, prevent declining of inoculants and nodular iron.

3. Enhance the cross section uniformity and prevent the shrink tendency.

4. Steady chemical composition. Even processing granularity.

Small deviation in quality and ingredients.

5. Low melting point(approaching 1300℃). Easy for melting absorb and has little dross.

Size:0.2-0.7mm,0.7-1.0mm,1.0-3.0mm,3.0-8.0mm

The size also can be produced as the customer's demand.

Producing process

High Carbon Ferrosilicon, also known as high carbon silicon, or silicon carbon alloy. This product is a by-product of the production of metal silicon. The main content is composed of silicon and carbon. Other contents are: silica, phosphorus, sulfur, etc. In the process of smelting metal silicon, the heating of the electrodes in the furnace is not enough. This causes the bottom of the furnace to reach the temperature required to produce metal silicon. Raw materials such as bottom silica and carbon are not fully reacted. After a long time of accumulation, silicon Carbon alloy is thus formed.

Advantages

1. Improve the quality of molten steel, improve product quality and improve product capacity.

2. Reduce the amount of alloy added, reduce steelmaking costs, and increase economic benefits.

Uses

The main content of high carbon silicon are silicon and carbon. It can replace ferrosilicon, silicon carbide, recarburizer . Reduce the amount of deoxidizer, and be used in converter smelting deoxidation alloying process. The effect is stable. The properties and quality of the steel are superior to the traditional process.
