Abstract
The present invention relates to a method for manufacturing a standard sample rapidly detected by a ZGMn13 material spectrograph, which has the following technology: (1) excellent ZGMn13 pure iron and the required alloy materials are used as furnace materials, a line frequency furnace is used as a smelting furnace, the furnace materials are cast into castings by a melting module in the temperature range of 1450 DEG C to 1490 DEG C, and the castings are selected and processed into sample blocks having the standard size after the water toughening processing; (2) the components of the sample blocks are analyzed; (3) the sample blocks are respectively excitated by a spectrograph according to the contents of the components of the obtained sample blocks, the light intensity value is collected, then the light intensity value and the contents of the components of the sample blocks are made into a work curve according to the use requirements of the spectrograph, and at least six sample blocks whose contents of the components are on the same curve in a linear gradient distribution mode are selected by means of interference correction, basal body correction and the like, namely the work curve made by the required standard sample blocks. The sample blocks are utilized to carry out spectrum analysis of ZGMn13, the contents of the components of ZGMn13 can be rapidly detected, and the requirements of the production technology for smelting ZGMn13 by an electric furnace can be satisfied.
Description
(1) technical field
The present invention relates to the material analysis field, particularly a kind of spectrometer that utilizes carries out the method for production of the standard specimen of fast detecting to ZGMn13 (a kind of manganese steel) material.
(2) prior art
To the analysis of ZGMn13 material, generally be to adopt conventional chemical analysis to detect the wherein content of C, S, Si, Mn, P five big elements, can determine the material of ZGMn13 according to the content of these five big elements.
The shortcoming of conventional chemical analytic approach is that analysis speed is too slow, can not adapt to the requirement of smelting process.Carry out material analysis with spectrometer and have fireballing advantage, but because the self-characteristic of ZGMn13 material can't carry out material analysis to it with spectrometer at present according to conventional method.And to carry out check and analysis to it with spectrometer, and then need to utilize a kind of satisfactory standard specimen to make the spectrometer working curve, this standard specimen should satisfy three conditions: 1) standard specimen will have six at least; 2) content of each element such as contained C, S, Si, Mn, P is answered distribution gradient in these six standard specimens, and for example: the content of " C " element is followed successively by 0.10%, 0.40%, 0.8%, 1.00%, 1.20%, 1.5% in six standard specimens.3) the standard specimen composition should not have segregation phenomena, and casting flaw can not be arranged.Also do not find such standard specimen in the market, also not seeing has document illustration to make the method for this standard specimen.
(3) summary of the invention
Task of the present invention is a kind of method that is used to manufacture the standard specimen that utilizes spectrometer fast detecting ZGMn13 material of invention.
Method of the present invention is such:
The method for production of ZGMn13 material spectrometer fast detecting standard specimen, it is characterized in that adopting following technology: 1) select for use top grade ZGMn13, pure iron and required alloy material as furnace charge, select for use main frequency furnace as smelting furnace, adopt investment casting, in 1450 ℃ of-1490 ℃ of temperature ranges, be cast into a certain size sample piece, after the tough processing of water, select, be processed into standard-sized sample piece again; 2) gained sample piece is carried out analysis of components, adopt carbon sulphur translocation titrimetry for C, S element; Adopt molybdenum blue colorimetric method for Si, P element; Adopt the ammonium nitrate oxidation ferrometry for Mn; 3) component content according to the sample piece adopts spectrometer that the sample piece is excited and gather light intensity value one by one, again the component content of light intensity value and sample piece is made the desired working curve of spectrometer, select on same curve component content with means such as interference correction, matrix corrections at last and be at least six sample pieces that linear gradient distributes and promptly get required standard specimen.
Described alloy material is electrode, ferrosilicon powder, silicon calcium powder, the carbon dust that manganese metal Mn, ferromanganese Fe-Mn, silicon-iron block Si-Fe, deoxidation fine aluminium, carburetting are used.
On spectrometer, utilize the prepared standard specimen of this method that the ZGMn13 material is carried out analyzing and testing, prove through long-time follow-up investigations (comprising arbitration inspection and interpretation of result), the rate that not only is up to the standards is up to more than 94%, and check speed is fast, can satisfy the arts demand of electric furnace smelting ZGMn13 well, thereby reach purpose with spectrometer fast detecting ZGMn13 material composition.
