The Quality Execution System (QES)
QuinLogic provides a revolutionary total quality assurance solution for “high end” steel and aluminum mills, which meanwhile has turned out to be the industrial standard in many well-known production sites worldwide. This innovative software product based on the Quality Execution System (QES) software suite offers better and more reliable quality for the challenging markets e.g. for automotive-, airplanes-, wind energy-, high strength- and wear resistant material grades. Its seamless communication interfaces to existing MES, ERP and gauging systems allows fully integrated systems in all existing but also new production lines.
For Highest Quality Metals
The key features of a Quality Execution System (QES) are to track quality including decision support per individual piece produced, exchange sequence related information with the MES and ERP systems and feed process related information back into the set-up for the next piece. From all these activities, decision support is obviously the most important and critical activity, given the amount of investments into advanced monitoring and gauging over the recent years.
To implement sophisticated quality decisions, a number of steps need to be taken:
- Data from various data bases as well as much raw data as possible must be processed.
- Data needs to be synchronized. A lot of data is time stamped (in various resolution from milli seconds to minutes as needed to guide the process. Decisions on products are not time based but per square meter and to decide, all data needs to be adjusted to match positions.
- Decisions are first (a) individual per type of data und then (b) combining several quality characteristics. This is essential because a piece of metal may still be good on temperature and reasonable on surface but in conjunction, it’s a block.
So, the core of a QES is definitively the data management. As a basis for a long, investment protecting roadmap, QuinLogic has created a Metal Object Model (MOM) as a foundation and backbone for all QES related applications.
Rule Progression through the process chain.
Centralized ruleset management and deployment.
Producing highest quality sheet metals means: make quality in every single step of a lengthy process chain. Advanced gauging technology is used to track the details, QuinLogic synchronizes all data and helps to analyze and to decide…
Quality Solutions for flat steel, long products, stainless steel, specialty steels, aluminum, copper and brass. With the given economic situation, customers look twice to verify receiving only the best quality. QuinLogic helps to analyze all of the large amounts of data that our customers and their gauging systems capture about a particular product. QuinLogic synchronizes all data to create a uniform data set per piece of metal that allows the utmost qualification before shipment.
Making perfect flat products is not about a final quality approval, it’s about sustaining defined quality levels throughout a lengthy process. Specifications are becoming tighter to the end of the process and options to correct / improve or change intended use of the product are also narrowing.
To improve operational excellence, the QuinLogic principle can not only be applied to a particular process step but for the entire process chain and the entire corporation. Our MOM has been geared to support all the genealogy aspects and can therefore even synchronize data among several process steps.
Closing The Loop – Process Optimization
Sustainable improvements to the production process are a logical consequence after deciding against shipment of certain products. With the Metal Object Model (MOM) in place, data analysis to uncover the root cause is taken to a new level. The data mining methods offered by QuinLogic have been created by BFI and several significant results have been achieved in the steel industry.
In cooperation with the research arm (BFI) of the German Iron and Steel association (Steel Institute VDEh) , QuinLogic is developing and marketing a data mining tool to uncover the root cause of certain process and product deviations. In particular, a lot of software support is available to incorporate data. Beyond the data, the software DataDiagnose comes with recipes to find the root cause. This does allow the use of the software by quality engineers at a particular line rather than relying on corporate research and statistics experts. Among the sophisticated methods included are multi-variate linear and non-linear correlation methods.
Customers using DataDiagnose include ArcelorMittal, Baosteel, Ternium and ThyssenKrupp.
