Reference national standard: ferrotitanium (GB/T 3649-2008)

product description:

The main component of ferrotitanium is an iron alloy of titanium and iron. It also contains impurities such as aluminum, silicon, carbon, sulfur, phosphorus, and manganese. Used as steelmaking deoxidizer, desulfurizer, degasser and alloying agent. In the process of steelmaking, it is added to the steel as an alloying element to refine the microstructure and grains, fix the interstitial elements (C, N), and improve the strength of the steel. There are three main varieties according to the content of titanium: FeTi30 (containing Ti25.0%～35.0%, Al<8.5%, Si<5.0%), FeTi40 (containing Ti35.0%～45.0%, Al<9.5%, Si<4.0%) and FeTi70 (including Ti65%~75%, A10.5%~5%, Si<0.5%).

Application range and purpose:

Titanium iron is used as deoxidizer, degassing agent and carbon-sulfur stabilizer in steelmaking. Deoxidation of titanium used in the production of killed steel can reduce the segregation in the upper part of the ingot, improve the quality of the steel and increase the yield of the ingot. The addition of titanium to cast iron is helpful for the formation of fine-grained graphite, and also plays the role of degassing, inoculating, purifying and refining the structure of the casting, and improving the wear resistance of the casting. The addition of titanium to heat-resistant cast iron can improve the heat resistance of the cast iron. In addition, titanium-containing composite alloys are used as additives for the production of superalloys and aluminum alloys. Welding electrodes use titanium iron as a coating component, which can improve the welding quality.
