Abstract
The invention belongs to the technical field of wheel steel production, and particularly relates to an analysis method of a steel chemical component sample for wheels. The method comprises the following steps: processing the steel chemical component sample for wheels; polishing the steel chemical component sample for wheels twice; and analyzing the steel chemical component sample for wheels. The analysis method of the steel chemical component sample for the wheels disclosed by the invention is accurate in component analysis; meanwhile, the defects which can exist in the sample can be timely checked out; and the sample can be timely sampled again, therefore, the problem that the production schedule is affected due to production hysteresis is avoided.
Description
Technical field
The invention belongs to wheel steel production technical field, particularly a kind of analytical approach of wheel steel chemical composition sample.
Background technology
At present, when chemical composition analysis is carried out to wheel steel, be in smelting and cast wheel process, molten steel sampled, analyzes its chemical composition.Prepared composition analyze sample time, adopt and disposablely polish analysis face.But, easily there is the situation of grinding depth deficiency in the way of this disposable polishing, causes specimen surface to there is oxide layer, and then the accuracy of impact analysis result.In addition, the way of disposable polishing can not carry out anticipation to the defect of sample, makes Operation delay of resampling, affects manufacturing schedule.
Summary of the invention
The object of this invention is to provide a kind of analytical approach of wheel steel chemical composition sample, result accuracy may be affected with what overcome that present analysis method exists maybe cannot carry out anticipation to sample thus affect the problem of manufacturing schedule.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
The analytical approach of wheel steel chemical composition sample, comprises the process of wheel steel chemical composition sample, described in be treated to wheel steel chemical composition sample is carried out twice polishing after analyze again.
Described wheel steel chemical composition sample is obtained by laxative remedy: from molten steel, take out liquor sample, pour sample mold into, solidify the initial samples of rear formation taper, again initial samples is cut into two parts from centre, obtain conical sample and truncated cone-shaped sample respectively, carry out polishing with conical sample wherein and analyze.
Described twice polishing is followed successively by corase grind and fine grinding.
The described corase grind degree of depth is not less than 2mm.
The analysis face whether existing defects of sample is checked after corase grind.
Described fine grinding refers to that polishing sample is to the requirement meeting constituent analysis sample.
Concrete, be finely ground to the analysis requirement that sample meets spectrometric instrument.
In the present invention, the object of corase grind is the oxide layer in order to remove specimen surface efficiently and effectively, because these oxide layers can produce considerable influence to the analysis result of sample.Corase grind uses thicker grinding wheel, grinds speed, does not carry out constituent analysis after corase grind.Fine grinding then uses and runs sample grinding machine more stably, and uses thinner grinding wheel to grind sample.The analysis face of sample is made to reach the requirement of spectrometric instrument.
Described wheel steel chemical composition sample sampling may be each period of smelting, as early stage, mid-term, later stage.
According to the inventive method, smelt and cast operative employee after sampling, sample is roughly ground and checks sample whether existing defects, as whether there is crackle, hole etc.; As zero defect, then sample is sent to analysis room, carries out fine grinding by analyst.If existing defects, then resample immediately, can not manufacturing schedule be affected.And after corase grind, the polishing of fine grinding twice, the patina of wheel steel chemical composition specimen surface has been efficiently removed, can not impact the accuracy of result.
Compared with prior art, tool has the following advantages in the present invention:
The analysis of analytical approach to composition of wheel steel chemical composition sample of the present invention is accurate, can check out the defect that sample may exist in time and resample in time simultaneously, avoids production delayed, affects manufacturing schedule.
