SiC Briquette
1. Introduction
Silicon carbide briquettesmade from silicon carbide scrap are used in the steel industry for processingsteel and iron scrap. It is used by the steel industry as a ladle deoxidizer, asource of silicon and carbon in the ladle, an electric furnace slag deoxidizer,and as a synthetic slag additive. According to Miller statistics, it costs less than ferrosilicon and carbon combination,produces cleaner steel due to low level of trace elements. It has low gascontent, and it does not lower the temperature of steel. It helps extend thehot steel supply and raises the tap temperature.
2.Characteristics andAdvantages
(1). It is a cost-savingsubstitute for Ferrosilicon.
(2). It has Multi-functions.
A: Removeoxygen from iron compound.
B: Adjustthe carbon content.
C: Act asa fuel and provide energy.
(3). It has no dust nuisancewhile feeding the material.
(4). It can speed up thereaction.
3. Chemical Compositions
Grade | Sic% | FreeC% | Si+SiO2% | Fe2O3 | MgO% | H2O% |
Sic75 | 75±4 | 2.5±1 | 17±2 | 3 | 0.16 | <5 |
Sic65 | 65±4 | 4.5±1 | 23±2 | 4 | 0.12 | <5 |

Sic45 | 45±4 | 5±2 | 31±3 | 7±2 | 0.1 | <5 |
4.Advantages
(1) Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities.
(2) Good hardness, longer life.
(3) Chemical washed and water washed good cleanness.
(4) Special treated products get higher purity, better toughness, and better grinding effect.
