What is ferrotitanium used for?

ferrotitanium Granule is used as deoxidizer, degassing agent and carbon-sulfur stabilizer in steelmaking. Titanium deoxidation is used in the production of killed steel, which can reduce segregation in the upper part of the steel ingot, improve the quality of the steel and increase the yield of the steel ingot. Titanium and nitrogen dissolved in molten steel can be combined to form stable titanium nitride, which can eliminate the adverse effects of nitrogen on steel properties.

Titanium and sulfur in the molten steel form titanium sulfide, which can eliminate the formation of iron sulfide that causes hot embrittlement. Titanium and carbon form extremely stable titanium carbide. The particles of titanium carbide can prevent the growth of steel grains, refine the structure of steel, and increase the strength of steel. The chemical affinity between titanium and carbon is greater than that between chromium and carbon. Adding FeTi to stainless steel to fix carbon can eliminate the depletion of chromium at the grain boundaries of stainless steel and improve the corrosion resistance of stainless steel.

In recent years, titanium has been used as a microalloying element to produce high-strength low-alloy steels. Adding titanium to cast iron helps to generate fine-grained graphite, and also plays the role of degassing, incubating, purifying and refining the casting structure, and improving the wear resistance of the casting. Adding titanium to heat-resistant cast iron can improve the heat resistance of cast iron parts. In addition, titanium-containing composite alloys are used as additives in the production of superalloys and aluminum alloys. Welding rods use ferrotitanium Ingot as the coating component, which can improve the welding quality.
