Rare earth ferroalloys make steel "better"

The addition of rare earth ferro alloys to steel can refine the steel grain size, alter inclusions, and improve low-temperature impact flexibility, strength, strong plasticity, and wear resistance.

Rare earth is known as "Penicillin" in steel. Many data studies have proved that adding rare earth elements to steel can not only improve the macrostructure of steel, such as refining dendrites, reducing porosity and segregation, but also can refine grains and improve microstructure; it can purify steel and make steel The deformation and reduction of non-metallic inclusions in the middle, the removal of gas, and the microalloying effect further improve the physical and mechanical properties of the steel.

The successful addition of rare earth ferro alloys to steel is naturally inseparable from its excellent properties.

Rare earth ferroalloys have suitable melting point and density, that is, the density is higher than slag, close to molten steel, and the melting point is higher than that of rare earth metals. high. In addition, rare earth ferro alloys have low activity, strong oxidation resistance, and are easy to store and transport.
