The Definition Of Ferro Titanium Powder

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 deoxidizer, desulfurizer, degasser and alloying agent for steelmaking. As an alloying element, it is added to steel in the steelmaking process, which has the functions of refining microstructure and grains, fixing interstitial elements (C, N) and improving steel strength.

Ferrotitanium is used as deoxidizer, degasser and carbon-sulfur stabilizer in steelmaking. Deoxidation of titanium for producing killed steel can reduce the segregation in the upper part of ingot, improve the quality of steel and increase the yield of ingot. Titanium and nitrogen dissolved in molten steel can combine to form stable titanium nitride, which can eliminate the adverse effects of nitrogen on steel properties. Titanium reacts with sulfur in molten steel to form titanium sulfide, which can eliminate the formation of iron sulfide that leads to thermal brittleness. Titanium and carbon form extremely stable titanium carbide, and titanium carbide particles can prevent the grain growth of steel, refine the structure of steel and improve the strength of steel. The chemical affinity between titanium and carbon is greater than that between chromium and carbon. Adding ferrotitanium to stainless steel to fix carbon can eliminate the dilution of chromium at the grain boundary of stainless steel and improve the corrosion resistance of stainless steel. In recent years, titanium has been used as microalloying element to produce high strength low alloy steel. Adding titanium to cast iron is helpful to the formation of fine-grained graphite, and also plays the role of degassing, inoculation, purification and refinement of casting structure, and improves the wear resistance of castings. Adding titanium to heat-resistant cast iron can improve the heat resistance of cast iron. In addition, titanium-containing composite alloys are used as additives in the production of superalloys and aluminum alloys. Using ferrotitanium as coating component for electrode can improve welding quality.
