On-site investigation: in order to the accomodation of activities of shooting the arrow at the target, determine movable desired value, 2012 are added up all fluorescence analysis raw material comparison test data qualifier rates, refers to shown in following table and Fig. 1:
1-6 month fluorescence analysis raw material contrast qualification rate data in 2012
As can be seen from the above table, within 2012, raw material contrast qualification rate is lower, and the first half of the year, mean value was 85.5%.The contrast qualification rate in February, 2012 is 92%, illustrates that we pass through to make great efforts to improve raw material contrast qualification rate.
the desired value of technical solution of the present invention: improve fluorescence analysis raw material contrast qualification rate, make raw material contrast qualification rate>=90%, require that fluorescence analysis raw material contrast qualification rate>=90%.
Carry out feasibility and analysis on Necessity for the target determined below: from present situation, in February, 2012 raw material contrast qualification rate is 92%, exceeds desired value, illustrates by analyzing each side reason, and strengthens management that to reach desired value be possible.
gameeing of technical solution of the present invention:according to causing raw material to contrast the low main cause of qualification rate, our QC-group has formulated concrete countermeasures, and makes strategy table:
the countermeasure of technical solution of the present invention is implemented:
Implement 1, for grinding machine, problem that sheeter fault is many, We conducted analysis:
Find that bottom mill seat be that several screws are fixed, because every day is vibrated back and forth, loosened screw, even fractures, and causing mill, running ash, for preventing this phenomenon, for this reason.We are welded bottom mill seat, there will be no loosened screw problem; Find that sheeter makes sample ftracture, be that therefore, we contrast by experiment for specific grinding machine and find out applicable pressure because sheeter pressure is inadequate simultaneously; Work as burn failure, when cannot use, contact producer carries out maintain and replace to mould.
grinding machine, sheeter essential factor verification the verifying results table
As seen from Figure 7: 1-7 month in 2012, i.e. movable front grinding machine, sheeter running rate is lower, and mean value is 84.70%, and the undulating quantity of the running rate of the moon is larger, after in August, 2012, namely after activity, grinding machine, sheeter running rate is higher, mean value is 94.73%, and running rate between the moon is more stable, and activity achieves good effect.
Implement 2, for the low problem of raw fluorescence running rate, We conducted analysis:
Raw material sample ash is large, because suction cleaner fails to clear up in time, cause suction cleaner suction inadequate, when raw material are detected, spectrometer can accurately not analyze the actual strength of each element of raw material, directly cause the fluctuation of batching, for this reason, we arrange specific post personnel to clear up suction cleaner every day, in the normal situation of suction cleaner, find around raw material prints steel ring and print surface still has a powdered sample time, post personnel will be subject to economic penalties.
spectrometer running rate low essential factor verification the verifying results table
As seen from Figure 8: 1-7 month in 2012, namely movable front spectrometer running rate is lower, mean value is 82.50%, and the undulating quantity of the running rate of the moon is comparatively large, after in August, 2012, namely after activity, spectrometer running rate is higher, mean value is 95.11%, and running rate between the moon is more stable, and activity achieves good effect.
Implement 3, for the large problem of the impact of grinding aid triethanolamine on raw material chemical composition, We conducted analysis:
Research finds, the intensity of grinding aid on raw material sample element has impact, therefore, we must control the addition of triethanolamine in certain scope, and the factor that maximum effect triethanolamine addition is constant, sample preparation error two factors between the damaged and post personnel of buret, to this, we require post once find that buret is damaged, must change at once, in post during examination on duty, also must practise the method correctly adding triethanolamine.
grinding aid essential factor verification the verifying results table
Raw material contrast qualification rate on average reaches 92.3%, and higher than predetermined target value 90%, illustrate that raw material element contrast qualification rate improves, development of the activity achieves good effect.Raw material contrast qualification rate has brought up to 92.3% by 85.5%, has grown 6.8 percentage points.
See Fig. 9, raw material contrast in November, 2012 in February, 2013 qualification rate on average reaches 94.9%, must exceed desired value 90% far away.Achievement consolidation period raw material contrast qualification rate reaches 94.9%.
raw material element contrast in November, 2012 in February, 2013 qualification rate
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
