Graphite powder in the metallurgical industry has the following applications and advantages:

Use：

Deoxidizer: Graphite powder can be used as a deoxidizer for deoxidizing treatment in the process of steel smelting. It reacts with oxides to form carbon monoxide, which weakens the presence of metal oxides and promotes the reduction of metal atoms, thereby reducing the oxygen content of the metal.

Refractory: Graphite powder, as a refractory material, is widely used in high temperature furnaces. Its high temperature stability, thermal conductivity and chemical stability make the graphite powder able to withstand high temperatures and corrosive gases, protecting metallurgical equipment from high temperatures and chemical erosion.

Alloy materials: Graphite powder can be used as an additive in metal alloy materials, which can enhance the mechanical properties, wear resistance and corrosion resistance of the material. The dispersion of graphite powder in the alloy is strong, which can improve the strength and toughness of the alloy.

Superiority：

High temperature stability: graphite powder has good stability at high temperatures and is not easy to melt or deform. This makes it an ideal choice for high temperature resistant equipment and materials in the metallurgical industry.

Good electrical conductivity: Graphite powder is a good conductive material that can effectively improve the electrical conductivity of metal liquids and promote the current flow and heat transfer in the smelting process.

Thermal conductivity: Graphite powder has high thermal conductivity, which can help evenly transfer heat and improve the utilization of heat energy in the metallurgical process.

Chemical stability: Graphite powder has good chemical stability in acid and alkaline environment and is not easy to be corroded. This allows it to be used in corrosive gas or liquid environments, extending the service life of the equipment.

The proportion of graphite powder used in casting may vary according to different applications and specific circumstances. In general, graphite powder can be used as an additive to improve the performance and quality of castings. Here are some common applications and usage ratios:

Sand casting: In the sand casting process, graphite powder can be used to improve the fluidity and anti-viscosity of the sand mold, reduce the tearing phenomenon of the sand core and improve the surface quality. Depending on the specific situation, the proportion of graphite powder used is generally between 0.5% and 2%.

Shell mold casting: In shell mold casting, graphite powder can be used to improve the thermal conductivity and fire resistance of the shell mold and reduce surface defects. Under normal circumstances, the proportion of graphite powder used is about 5% to 10%.

The proportion mentioned above is only a general reference value, and the specific proportion of use may vary due to factors such as materials, casting methods, and production requirements.
