Abstract
The invention relates to a control method of quality management, and particularly relates to a control method for electrolytic aluminum factory production process quality management. Processes needed to be sampled and tested are sampled and tested in an electrolytic aluminum production process, quality basic data are formed according to the data of the sampling and test, a statistical report and statistical data which are used for quality statistics are formed according to the quality basic data, the statistical data are used for a quality analysis and a quality prediction, the quality prediction forms a quality plan to provide data for the quality analysis, and a quality difference solving method is acquired after the quality analysis and is used in the electrolytic aluminum production process. The control method has the advantages that real situations in the electrolytic aluminum factory quality management process are fully considered, the overall process of the electrolytic aluminum factory production process quality management is controlled, quality accident is reduced, and the safety of producing products is improved.
Description
Technical field
the present invention relates to a kind of control method of quality management, relate in particular to a kind of control method for the quality management of electrolytic aluminium factory production run.
Background technology
Quality management is an important component part of electrolytic aluminium factory production management, the quality of quality management process control is directly had influence on to the survival and development of enterprise.Although current most electrolytic aluminium factory can be according to the actual production situation of enterprise and for the demand of quality management, form more complete quality management scheme, but still exist some problems, for example: the control framework design of part electrolytic aluminium factory quality management process lacks scientific, cannot utilize the qualitative data of magnanimity to instruct producing, in the time that the quality of production goes wrong, also the reason that problem analysis timely and accurately occurs, waste the resources of production of enterprise, improved enterprise's production cost.
Summary of the invention
The invention provides a kind of control method for the quality management of electrolytic aluminium factory production run in order to solve the problems of the technologies described above, object is that the overall process of electrolytic aluminium factory production run quality management is controlled, and reduces quality accident, improves the safety of producing product.
The invention provides a kind of control method for the quality management of electrolytic aluminium factory production run for reaching above-mentioned purpose, in Aluminum Electrolysis Production process, the step that needs inspection by sampling is carried out to inspection by sampling, and according to the data formation quality base data of inspection by sampling, statistical report form and the statistics used with quality base data formation statistic of attribute, statistics is for quality analysis and prediction of quality, prediction of quality forms quality planning for quality analysis provides data, obtains the method for mass discrepancy solution and be used in Aluminum Electrolysis Production process after quality analysis.
Quality base data provide foundation for quality monitoring in Aluminum Electrolysis Production process.
Statistical report form offers quality examination process and forms examination form.
Inspection by sampling comprises the hour data of electrolysis plant laboratory analysis data and production scheduling, and wherein the analysis data in electrolysis plant laboratory comprises aluminium oxide, cryolite, aluminum fluoride, magnesium fluoride, molecular proportion, the result of laboratory test of primary aluminum and finished product aluminium; The hour data of production scheduling comprises the key process parameter in the each workshop of full factory, for example: the compressed air pressure that compressed air station provides, the quality examination indexs such as rectifier potline current.
Statistic of attribute comprises the statistic of attribute of each procedures class, each operation statistic of attribute and the each operation statistic of attribute monthly of every day.
Prediction of quality is predicted crucial technic index according to historical data, makes field personnel can hold in time product quality level and the variation tendency thereof of next day, forms the feedforward control of quality management process.
Suitable quality index is selected in quality analysis, icon display analysis in a variety of forms, actual value and planned value to critical process index compare, the situation that exceeds deviation range is analyzed, clearly affect the principal element that product quality changes, form the FEEDBACK CONTROL of quality management process, for quality control provides foundation.
Quality monitoring can be inquired about over hour quality index, day quality index of the each procedures of random time class easily and be realized the real-time monitoring to whole production run.
Quality examination: statistics generates operating crew's quarterly review table, for examining the different work class of each operation, different operation areas.
Advantageous effect of the present invention:
The present invention takes into full account the actual conditions of electrolytic aluminium factory quality management process,
rightthe overall process of electrolytic aluminium factory production run quality management is controlled, and reduces quality accident, improves the safety of producing product.
