Ferroniobium an iron alloy with niobium and iron as its principal components. It also contains impurities such as aluminum, silicon, carbon, sulfur and phosphorus. According to the content of niobium alloy is divided into FeNb50, FeNb60, FeNb70. The iron alloy produced from niobium tantalum contains tantalum and is called niobium tantalum iron. Iron niobium and niobium-nickel alloys are used as niobium additives for iron and nickel alloys in vacuum smelting. Require low gas content, low harmful impurities, such As Pb, Sb, Bi, Sn, As, etc. 2×10-6, so the title "VQ"(vacuum mass), such as VQFeNb, VQNiNb and so on. The niobium-ferromanganese alloy produced in China (NB10% ~ 15%) is used as alloying agent for low alloy steel and niobium treatment agent for carbon steel.

In stainless steel and heat-resistant steel, niobium carbonates stably with carbon in the steel. It IS DISTRIBUTED UNIFORMLY ON THE GRAIN boundary OF STEEL, prevents the grain growth of steel at high temperature, plays a role in refining the structure of steel, and can improve the strength, toughness and creep properties of steel. The chemical affinity of niobium and carbon is much greater than that of chromium and carbon. Therefore, when there is niobium in stainless steel, chromium carbide can be prevented from precipitate at the grain boundary of steel, thus improving the corrosion resistance of steel. The niobium and nitrogen in the steel form stable niobium nitride, which improves the corrosion resistance of the steel surface. Niobium in steel and oxygen to form stable niobium oxide, so that the surface of the steel to form niobium oxide film, can prevent oxygen to the interior diffusion and play the role of oxidation. Adding NB0.015% ~ 0.05% to carbon steel can refine the structure and make the steel have good formability and welding performance. Niobium strongly prevents the austenite recrystallization of steel, so that steel rolling can be effectively controlled at higher temperature, and the effect of strengthening and toughening is very remarkable. So niobium as a microalloying element in carbon steel dosage greatly increased. Production Process of Ferro Niobium Ferroniobium has been produced by traditional thermite process since 1965. In the early 1990s, the process of producing niobium iron by semi - continuous self - heating reduction was established. The reactor for thermite smelting is fixed and equipped with a furnace cover. The slag and niobium iron produced by the reaction are discharged from the furnace. The prepared raw materials will be loaded into the designated cylindrical bin with the material tank. Features of Ferro Niobium 01. Niobium plays the role of solution strengthening and carbide precipitation strengthening in superalloy, which can improve the yield strength and surface stability of superalloy. 02. The weight of niobium is one of the lighter refractory metals, which is also one of the factors in the large use of superalloys. 03. The coercivity properties of permanent magnet alloy can be improved by adding niobium. The addition of niobium in cast iron is helpful for spheroidization and formation of pearlite structure. It plays a role in breeding and refining the casting structure. 04. Niobium can improve the strength, toughness, hardness and service life of castings at high temperature.
