Abstract
<b/><b/><b/><b/><b/> the invention provides a kind of novel reducer producing the complex ferroalloy of vanadium iron and vanadium---silicon barium-ferrum alloy.Make reductive agent with silicon barium-ferrum alloy, not only carbon containing low (C≤2%) in the alloy of the vanadium iron produced in electric reduction furnace and the complex ferroalloy of vanadium, and reduce production cost, have good economic benefit and social benefit.
Description
Technical field
The present invention relates to a kind of for making steel material---the complex ferroalloy production method of ferro-vanadium and vanadium.
Background technology
Vanadium uses mainly as steelmaking alloy element.The crystal grain of vanadium energy refinement steel, improves hardness and the wear resistance of steel, can improve tensile strength and thermotolerance, improve the effects such as the machining property of steel.Vanadium is a kind of element be highly profitable in steel.
In steel-making, vanadium mainly adds in steel the alloying realizing vanadium with ferro-vanadium.At present, the conventional production process of vanadium iron makes raw material with Vanadium Pentoxide in FLAKES, makes reductive agent smelting ferrovanadium alloy in electric reduction furnace (mineral hot furnace/electric arc furnace) with Silicified breccias or aluminium.Namely electro-silicothermic process or thermite process is claimed to produce vanadium iron.When making reductive agent with carbon, carbon 4-6%(mass percent can only be obtained as follows) carvan, and carvan cannot use most of steel alloy, so method is not promoted.Silicified breccias price is more expensive, and produce vanadium iron with Silicified breccias or with al reducing agent, production cost is high, increases the cost of steel-making, affects economic benefit.
Summary of the invention
The object of the present invention is to provide reductive agent---the silicon barium-ferrum alloy of the complex ferroalloy of a kind of novel production vanadium iron and vanadium, thus reduce the production cost of vanadium iron, increase economic efficiency.
The present invention is that silicon barium iron makes reductive agent production low-carbon (LC) (C≤2%) vanadium iron and vanadium complex ferroalloy.Alternative Silicified breccias or aluminium make electro-silicothermic process and the thermite process production vanadium iron of reductive agent.In order to improve the reducing power of silicon barium iron, other deoxidant elements can also be added in silicon barium-ferrum alloy, as: aluminium, calcium etc.
Silicon barium iron is used for deoxidation just to start to use in steel-making in the 1980s, was emerging deoxygenated alloy.Its deoxidizing capacity and strong deoxidant element---aluminum ratio 1.1-1.3:1, deoxidizing capacity is suitable with aluminium, and price is but about 1/3 of aluminium.Strong with deoxidizing capacity, the silicon barium iron that price is low is made reductive agent production vanadium iron and can be reduced costs, and creates good economic benefit and social benefit.
Reductive agent made by the present invention's silicon barium iron, makes the complex ferroalloy of raw material production vanadium iron and vanadium with Vanadium Pentoxide in FLAKES, also can make the complex ferroalloy of raw material production vanadium iron and vanadium with Vanadium Pentoxide in FLAKES and vanadium slag allotment; The also complex ferroalloy of available vanadium slag raw material production vanadium iron and vanadium; Require according to alloying constituent and select raw material.Produce the available Vanadium Pentoxide in FLAKES of more than the complex ferroalloy containing vanadium 40% vanadium iron and vanadium and make raw material, make reductive agent with silicon barium iron, produce in electric reduction furnace; Produce containing the vanadium iron of vanadium 20-40% and the complex ferroalloy of vanadium, raw material is made in available Vanadium Pentoxide in FLAKES and vanadium slag allotment, makes reductive agent, produce vanadium iron and vanadium complex ferroalloy at electric reduction furnace with silicon vanadium iron; The vanadium iron produced containing vanadium less than 20% can make raw material by direct vanadium slag, makes reductive agent, produce the complex ferroalloy of vanadium iron and vanadium in electric reduction furnace with silicon barium iron; Produce and be less than in the ferro-vanadium of 40% containing vanadium, can also baric and element silicon.Desoxydatoin can be played in molten steel containing silicon, barium in vanadium iron, thus ensure the alloying action of vanadium in molten steel, improve the utilization ratio of vanadium.In the complex ferroalloy of described vanadium containing steel-making needed for alloy element and deoxidant element, as: silicon, manganese, chromium, barium, titanium, calcium, aluminium, magnesium etc. one or more.
