Abstract
The invention discloses the rapid analysis methods of nitrogen content in a kind of production of silicon steel, include the following steps: to grind off the rodlike sample outer oxide layer of silicon steel, pelletizing, using the input mode of upper sample introduction using abrasive band, melting-thermal conductivity method quickly measures the values of nitrogen might of silicon steel process sample, guarantees the smelting time limit of silicon steel.
Description
Technical field
The invention belongs to Ferrous Metallurgy make steel assay technique field, more particularly, to a kind of silicon steel production in nitrogen content it is fast
Fast analysis method.
Background technique
Nitrogen content in " photo-electric direct reading spectrometer measures the nitrogen in silicon steel " paper direct-reading spectrometer measurement silicon steel.It grinds
Suitable analysis condition is studied carefully and the preparation requirement of analysis sample has been determined, Accurate Determining nitrogen content is in 0.0080%-
0.0130% sample.
" raising of Analysis Precision on N-element in Oriented Silicon Steel " paper by stick sample biplate cutting machine slice sample, then
The paste that will turn blue partially is ground off, then goes out block sample with perforating press, using upper input mode, melting-thermal conductivity method measurement silicon steel nitrogen
Value, article analyze the influence that grind away condition, analysis condition, input mode analyze silicon steel values of nitrogen might.
" input mode analyzes nitrogen in steel constituent content under melting thermal conductivity method " describes, and utilizes inert gas fusion thermal conductivity
Method considers nitrogen element content in shape steel sample to be worth doing using input mode detection under ONH Conjoint Analysis instrument.Article discuss sample shape,
Analysis condition influences analysis result, and verifies to the accuracy of method, precision.
Beneficial effect of the nitrogen in silicon steel production is the toughness and welding performance that can improve steel, and nitrogen still causes silicon steel
An important factor for piece magnetic aging, nitrogen also have a great impact to the quality of orientation cold rolling transformation, excessive or very few nitrogen content meeting
Cold-reduced silicon sheet is set to obtain big crystal grain and high magnetism, the adverse effect of nitrogen is that it is nonmetallic that it, which generates nitride with alloying element,
It is mingled with, it is often more important that reduce alloys producing, therefore, the quick analysis of nitrogen process sample especially acts on production
And how to develop a kind of need that novel liquid steel nitrogen content rapid analysis method optimizes as current silicon steel production technology
It wants.
Summary of the invention
The object of the present invention is to provide the rapid analysis methods of nitrogen content in a kind of production of silicon steel, to guarantee the smelting of silicon steel
Time limit.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
The rapid analysis method of nitrogen content in a kind of production of silicon steel includes the following steps: to grind off silicon steel using abrasive band rodlike
Sample outer oxide layer, pelletizing, using the input mode of upper sample introduction, melting-thermal conductivity method quickly measures the values of nitrogen might of silicon steel process sample, protects
Demonstrate,prove the smelting time limit of silicon steel.
Further, the pelletizing uses cutter pelletizing.
Further, the abrasive band is zirconium oxide abrasive band.
Further, the rodlike sample outer oxide layer of silicon steel is ground off by manual operation using abrasive band.
Further, using upper input mode, sample is preposition in crucible in degassing.
Compared with prior art, advantageous effects of the invention:
Using belt sanding sample surfaces, manual operation guarantees sample without paste sample, reduces sample preparation to greatest extent to sample
Influence, reduce influence of the sample preparation to nitrogen in steel value, guarantee that result is quickly authentic and valid, effectively instruct process for making while avoiding
Process data delay and cause into；Sample preparation speed is fast, easy to operate, can quote analysis average result in 5 minutes；Using upper
Input mode, sample is in preposition in crucible, influence of the reduction air to analysis result that deaerate.
Specific embodiment
The rapid analysis method of nitrogen content, grinds off the rodlike sample outer layer oxygen of silicon steel using zirconium oxide abrasive band in a kind of production of silicon steel
Change layer, cutter pelletizing, using the input mode of upper sample introduction, melting-thermal conductivity method quickly measures the values of nitrogen might of silicon steel process sample, guarantees
The smelting time limit of silicon steel.
Technical solution of the present invention is particular in that:
(1) sample handling processes are compared to bits shape sample preparation, and contaminated probability is small during the preparation process for sample, guarantee sample
Authenticity and representativeness.
(2) belt sanding sample surfaces are used, manual operation guarantees that sample without paste sample, reduces sample preparation pair to greatest extent
The influence of sample；Sample preparation speed is fast, easy to operate, can quote analysis average result in 5 minutes.
(3) input mode in use, sample is in preposition in crucible, influence of the reduction air to analysis result that deaerate.
The present invention grinds sample using abrasive band for analysis sample characteristics of for example and requirement according to the requirement of steel making working procedure, maximum
Representativeness, the authenticity of the guarantee sample of limit, realize the target that silicon steel process sample is analyzed in 5 minutes, cooperation accurately and timely
Process for making.The technique method that the present invention takes will not be such that sample hair paste guarantees to reduce influence of the sample preparation to nitrogen in steel value
As a result quickly authentic and valid, it effectively instructs process for making while avoiding the increase that process data is delayed and leads to cost.
Through implementing to verify., the nitrogen of this method completes average value (2 points are quoted a point value in 30 seconds) in five minutes,
So that refining, RH is accurately controlled the additive amount of raw material, reduce waste, effectively control cost.Accurately analysis silicon steel process sample exists
The values of nitrogen might of the content of 0.0010%-0.0130, existing application effect is stablized, and improves the yield rate of product.
Embodiment described above is only that preferred embodiment of the invention is described, and is not carried out to the scope of the present invention
It limits, without departing from the spirit of the design of the present invention, those of ordinary skill in the art make technical solution of the present invention
Various changes and improvements, should all fall into claims of the present invention determine protection scope in.
