Carbon raisers are becoming more and more popular now, mainly because of their low price, good quality, wide range of uses, etc. Now the various carbon raisers in the ferroalloy market are dazzling, so you should know what elements are contained in the carbon raiser for you to choose, and at the same time, you can better use the carbon raiser. What elements are contained in the carbon raiser?

 

1. Moisture
The total moisture index of the carbon raiser should be as low as possible. The moisture brought into the molten steel will increase the hydrogen content in the molten steel. The total moisture depends on the quenching process, storage and transportation conditions. ≤l%, the raw material coke moisture content before crushing and packaging should be ≤3%.

 

2. Ash
The dry basis ash index for carbon increase should be kept low. The ash content brought into the molten steel will increase the impurities in the molten steel and increase the inclusions. Because the ash quotient of different types of carbon raiser varies greatly, the ash content of calcined petroleum coke is relatively low, about 0.5-1.0%, and the ash content of calcined anthracite is relatively high, and the high-quality ones will not be less than 4-5%. The index value is calculated on a dry basis, which can eliminate the influence on the ash value caused by the fluctuation of the moisture of the carbon raiser.

 

 

3. Volatile
The dry-based volatile content of the carbon raiser should also be kept low. Volatile is the ineffective part of carbon raiser, and the volatile entering the molten steel will also increase the gas content in the copper water. The dry-based volatile depends on the calcination or coking temperature of carbon raiser and the treatment process, and the properly treated carbon raiser is below 0.5%.

 

4. Carbon
The carbon of carbon raiser is the really useful part. The higher the value, the better. According to the carbon index value of carbon raiser, it can be divided into several brands, such as: 99%, 98.5%, 97.5%, 95%.

 

5. Sulfur
The sulfur content of carbon raiser is an important harmful element as low as possible. The sulfur content of carbon raiser depends on the sulfur content of the raw material and the calcination temperature.
