In general, the carburant particles are small, the dissolution rate is fast, and the loss rate is large; the carburant particle size is large, the dissolution rate is slow, and the loss rate is small.

For example, in a 110kg high-frequency induction furnace, the carbon raiser with a particle size of 15-18mm dissolves very quickly, and most of it is dissolved in the molten iron before it is oxidized and lost, and only a small part is lost, so the absorption rate is high.

In a 60kg induction furnace, the diameter and capacity of the hearth are relatively large, and the particle size of the recarburizer is 15-18mm, which is too small compared to the diameter and capacity of the hearth, so the loss rate is fast and the absorption rate is low; while the particle size of 116-312mm is relatively small compared to the diameter and In terms of capacity, the recarburizer has a faster dissolution rate and a slower loss rate, and the dissolution plays a dominant role, with a high absorption rate.
