What are the differences between different carbon additives?
The quality of different carbon additives varies. For instance, there are graphite carbon additives and coal-based carbon additives. Although they are both carbon additives, they differ in basic characteristics, absorption coefficients, prices, advantages and disadvantages, etc. It is not very large, but if not applied properly, it can also affect their carbon-increasing effect.

What are the functions of low-nitrogen carbon additives
Although, after a period of development, the types of carbon additives have been increasing continuously, and different carbon additives have different characteristics and are applied in different fields.
What are the characteristics of low-nitrogen carbon additives?
What characteristics should a good graphite carbon additive have?
A good graphitized carbon additive should also have the characteristics of high carbon content, fast decomposition speed and high absorption rate. (2) A good graphitized carbon additive has very low levels of harmful elements and features low sulfur and low nitrogen. (3) Add graphite carbon additive to the molten steel and molten iron, and add it in layers more evenly. It can refine its distribution in molten steel and molten iron, making the absorption and performance more stable. (4) Generally, when in use, choosing the size of different particles based on the size of the furnace, power and dissolution time is also crucial. Generally, particles with a size of 0.2-2mm and 1-5mm are more commonly used.
