Petroleum coke Recarburizer for steel Melting High Carbon of Green graphitized calcined for Metallurgy and Foundry

Carbon raiser is a carbon material, produced at high temperatures and used for carburization of steel and cast iron.

It is applied during the steelmaking with low cast iron content (allow of steel and carbon) in charge in oxygen converter and electrosmelting processes. In metallurgy carbon raiser (milled graphite) is widely used for slag foaming, during coal graphite production, as a filler for graphite-reinforced plastic.

Using methods

Adjust carbon points,put into the centrai lower part of furnace with metal materials,the yield car reach 90%-95%;

Acust the carbon after the molten steel meit, put it on the surface of moiten steel. finally,the rate is about 66% by riten steel’ s swirt stirring or artificial mixing.

Advantages of carburizers

High fixed carbon, high absorption rate

Low-sulfur and low-nitrogen, and the absorption speed is faster than similar graphitized recarburizers, and it does not adsorb to the furnace wall and absorbs completely without residue. The price is lower than similar low-sulfur products, and the price is high.

1. The absorption rate is high, and the absorption rate can reach more than 90% or even higher according to the application method.

2. The absorption speed is fast, which is faster than that of similar graphitized recarburizers. It does not adsorb to the furnace wall and has no residue, and the absorption speed of recarburization in the furnace is more obvious.

3. Low sulfur content, below 0.05%, or even lower, low nitrogen content, below 300PPM.

4. Super high cost performance is very competitive in price among similar products.
