Description
Technical field
The invention belongs to metallurgical technology field, be specifically related to nitrogenized manganese vanadium iron and production method thereof.
Background technology
The performance of steel to be improved by the strengthening means of necessity in steel-making production process, the strengthening element that tradition uses have niobium, vanadium, titanium, etc. metallic compound.
Along with the continuous increase of present steel cost pressure, different strengthening means are also constantly being used. and related data research shows, by adding the compound of nitrogen and vanadium in steel, VN, VC or V (C in steel, N) be the emission form main in austenite of vanadium, play the effect of precipitation strength, because the avidity of V, N is greater than the avidity of V, C, namely first form VN at identical conditions.
Use in the steel of FeV microalloying, V is mainly present in the middle of matrix with solid solution state, seldom can separate out with the form of V carbonitride and produce the effect of precipitation strength.And work as with in the steel of VN microalloying, then have a large amount of V to separate out with the form of V carbonitride, do not have the V be solidly soluted in the middle of matrix to exist, because the wherein existence of a large amount of N, V is preferentially combined with N, forms VN compound, wherein solution V becomes the VN compound separating out state, change it at alternate distribution form, have obvious precipitation strength effect.
At present in steelmaking process because nitrogen content is not enough, cause the DeGrain that VN strengthen, this increases enough nitrogen with regard to needs and carries out in steel, and simple carries out nitrogen blowing, because the problem of solubleness can not form effective nitride.Therefore, join in steel with the form of nitride, improve the ratio of nitrogen in steel content, play the effect of solution strengthening.
Summary of the invention
The object of the present invention is to provide nitrogenized manganese vanadium iron and production method thereof, this nitrogenized manganese vanadium iron is a kind of reinforced alloys used in steelmaking process, improves V precipitation strength ability, stablizes specific absorption and the index of stability of nitrogen.
It is more than the present invention that alleged problem is solved by following technical scheme:
Nitrogenized manganese ferro-vanadium, is made up of following compositions: vanadium 35-50%, manganese 30-45%, nitrogen 10-18%, carbon≤0.6%, silicon≤2.0%, phosphorus≤0.3%, sulphur≤0.02%, and surplus is iron and inevitable impurity.
Based on the production method of above-mentioned nitrogenized manganese ferro-vanadium, comprise the following steps: the consumption calculating vanadium iron and nitrided ferromanganese according to mentioned component ratio, described vanadium iron, nitrided ferromanganese fragmentation are loaded in sealed vessel or stove, vacuumize and reach-0.03 ~-0.04MPa, then the nitrogen of 0.02 ~ 0.05MPa is passed into, intensification is heated to 1200-1250 DEG C, and insulation 4-6 hour, carries out being cooled to 20-50 DEG C in nitrogen atmosphere.
Vanadium iron of the present invention is tablet vanadium iron.
In nitrided ferromanganese of the present invention, Fe content is 75-85%.
The purity of nitrogen of the present invention is more than 99.9%.
Soaking time of the present invention is 5 hours.
Vanadium iron of the present invention, nitrided ferromanganese crushing granularity requirement 50-150 order.
After vanadium iron of the present invention, nitrided ferromanganese fragmentation, use polyvinyl alcohol to carry out pressure ball process for binding agent, the additional proportion of material and binding agent is 100:1-10.
The beneficial effect adopting technique scheme to produce is: product of the present invention forms nitrogenized manganese vanadium iron by nitrided ferromanganese and vanadium iron being carried out combination, effectively make use of the microalloying of the higher and vanadium iron of nitrogen content in nitrogenized manganese, effectively improve the problem of the nitrogen content deficiency in nitrided ferromanganese, nitrogen in steel content can be increased in the use procedure of nitrogenized manganese vanadium iron, form the strengthening of effective vanadium nitride, it is 12-15 yuan/ton that ton steel can reduce cost of alloy, has obvious lifting to microalloying effect.
