Description of Ferrotitanium
Ferrotitanium is an iron alloy composed of titanium and iron. It also contains impurities such as aluminum, silicon, carbon, sulfur, phosphorus, and manganese. Used as deoxidizer, desulfurizer, degassing agent, and alloying agent in steelmaking. It is added to steel as an alloying element during the steelmaking process to refine the structure grains, fix interstitial elements (C, N), and improve the strength of the steel.
The melting point of ferrotitanium ranges from 1400℃ to 1500℃ due to its different chemical composition, and its density is 5.7-6.4g/cm³.

2 methods of manufacture
Thermite self-propagation method
The high-temperature self-propagation method, also known as the high-temperature synthesis method, is to press the powder prepared according to the formula into a compact, and then select a suitable external heat source to ignite it to start the reaction. The chemical reaction releases a large amount of heat to form a high temperature. As the reaction proceeds, The combustion wave formed at the same time propagates downward, causing the nearby unreacted area to heat up and cause new reactions suddenly. When the combustion wave moves downward, the upper reaction has ended and been converted into products, and the lower reaction is still going on, and so on. Continue until all reactions are completed and the overall product is formed.
Carbon reduction method
To reduce the consumption of aluminum powder in the production of iron-ferroalloys, the process of producing titanium-ferroalloys by the carbothermal method was developed. This process is suitable for producing ordinary grades of alloy steel with large output. The outstanding features of this ferrotitanium alloy are its low price and low content of non-ferrous metal impurities.
