Characteristics of graphite carburizer

Nov. 10, 2023

Graphite carburizer is used in casting, cast iron, cast steel and other fields, castings have a requirement for carbon, so graphite carburizer is mainly to increase the carbon content in liquid iron. So let's count what are the characteristics of graphite carburizer?

The first characteristic is high fixed carbon, high absorption rate, low sulfur, low nitrogen, the absorption rate is faster than the absorption rate of the same graphitized carburizer, and it is lower than the price of the same graphitized carburizer whose sulfur content is less than 0.05.

The second is that the absorption rate of graphite carburizer is high, and the absorption rate is higher than 90 according to the use method.

Third, the graphite carburizer absorbs fast, does not adsorb the furnace wall, and has no residue, so the advantage of improving the carbon absorption rate in the furnace is more obvious.

Fourth, the sulfur content of graphite carburizer is low, below 0.05, lower than 0.02, and the nitrogen content is low, below 100 ppm. Fifth, graphite carburizer has a high cost performance.

In the smelting commonly used charge for pig iron, scrap, return charge, the carbon content of pig iron is high, but the purchase price is higher than scrap, so increase the amount of scrap, reduce the amount of pig iron, add graphite carburizer, can play a certain role in reducing the cost of casting.
