Quality Of Products

Currently, more and more challenges of modern industrial enterprises require an increase in the reliability of the information on the quality of products. This becomes possible when using digital technologies to assess the quality of products. The cited publication discusses the technology for recognizing defects in the surface of sheet products in images obtained from cameras of the strip inspection system during rolling. The authors proposed a classification of the signs of defects in the image and highlighted the most significant of them also suggested using geometric, optical and spectral features for images of flat-rolled products containing defects of different classes. The research results at this stage, obtained during the processing of digital images, showed that to identify a defect and reduce false-positive and false-negative alarms of the automated defect identification system, it is required to conduct a study of interval estimates and make decision-making rules based on intersection and merging of intervals; introduce additional classes that allow the introduction of signs that characterize the irregularity of the shape of defects and the characteristic location; the use of new technologies of soft computing will reveal the hidden patterns of the manifestation of defects in the images of the surface of the steel strip.

Quality Of Products

This publication aims to define the driving forces for the formation of quality knowledge and their practical role in the business and healthcare system, which is important for each manager in terms of quality development and quality management. Documentary and historical methods have been explored over many scientific publications. Quality concepts have been explored to give an insight into the nature of both types of needs - the manufacturer and the consumer, and how they have been managed over time so they have "altered" the quality of products and services by creating new features. Quality concepts deliver the first and most important factor in shaping quality - the needs of entrepreneurship and consumers. In the business sphere, the factors influencing the quality are manifested through the "Integrated Quality Control System and are: policy, information, design and construction, materials, equipment, labor resources, maintenance. The factors determining the development of the quality of products / services in the economic and medical spheres can be classified into five groups: needs, economic factors, market, achievements of science and technology - new technologies, education - development, level of professional qualities, public relationships, level, person and social environment and governance. They have different influence and strength in each of the two spheres Among the factors for the development of quality there is dependence and mutual influence, arising from the relations in the society, based on the economic relations. Their core is built up by the two types of needs - those of the manufacturer and those of the user. By their very nature, they are antagonistic needs linked to different individual motives, which are the subject of a separate study. Combining and synchronizing individual and public interests is a factor in shaping the welfare state policy.

Quality Of Products

Industrial enterprises increasingly demand optimum quality of products keeping in consideration a strict adherence where forming parameters are concerned. As far as incorporating the vital forming process upon an assortment of materials is concerned, it has grown excruciatingly challenging for industrial enterprises for laying out the adequately precise and suitable parameters. The flaws that are engendered during the process of sheet metal forming are inevitable. Flaws of this nature can be, however, kept within minimal proportions by introducing variations into the process parameters by Trial and Error methodology. This evidently results in a subsequent financial loss, not to mention an irrevocable loss of time and material. Dynaform simulation of defects combined with optimization is carried out with the help of Minitab. This method, as can be conjectured with considerable ease, yields optimum results, for it replaces much to our convenience the need for specialist industrial expertise besides leading to considerable savings in cost, time and material. This study would optimize the SS304sheet metal forming parameters FLD, thickness and thinning with three input parameters, namely, the lower binder force, tool travel velocity and binder close velocity.

This thesis explores possible improvements to the existing defect detection sys-tems used by Tata Steel Europe in South Wales. Exploring the possibilities of ac-curacy increases and further uses for in-house surface quality systems presents Tata Steel Europe with methods and considerations on how to improve their current surface defect management tools. This research considers three dif-ferent aspects of the defect management process and tests alternatives to the systems either currently used or not yet in place.The first section considers an ensemble object detection method using Gabor filters, histograms, and a random forest classifier. The algorithm was applied originally as an ensemble method and then as a case-study it was split into two combinations of the methods to determine what level of ensemble complexity was optimal. The images used were a set of various types of steel defect im-ages provided by Tata Steel Europe. The ensemble method achieved acceptable results compared to the existing systems, but the medium-complexity method was optimal regarding overall accuracy, false negative rate, and speed. The sec-ond section used a set of weld hole images which were split into three quality grades by defining characteristics of the feature. These images were used to test three different neural networks, an R-CNN version of GoogLeNet, and Faster R-CNN versions of ResNet-50 and ResNet-101. These networks were tasked with classifying the quality of weld holes in steel. Accurately detecting weld holes is vital in steel production as certain production processes require speed changes for welds. As the hole punches degrade over time, so does the quality of the weld hole. When weld holes are of poor quality, they can be missed or wrongly detected. All three networks detected the weld holes very well, but classifying the quality grade was approximately 60% accurate for both ResNets and 79% accurate for the GoogLeNet. These tests highlighted the importance of data quantity and quality, including lack of bias in data. The third section looks at how colour filters and greyscale methods can affect the images used for detection and classification. An investigation into coloured light sources has not been fully explored at Tata Steel in South Wales before. Having worked with the image data for sections one and two, it highlighted how important the quality of these images is. Steel defect samples were supplied, alongside their lab-confirmed defect label. Scans were taken of clean and oiled steel samples with different coloured filters and a variety of common greyscale methods were used to turn these images from RGB colour to greyscale images. The greyscale values of defect to clean steel were calculated for a specific region of interest on each steel sample. This value was used as a measure of contrast between clean and defect steel. The yellow filter with the Decolorize method produced the highest contrast image, higher than using no filter at all. For oiled sam-ples, using no filter with the Decolorize method produced the best contrast and the orange filter with the Decolorize method produced the best contrast out of the filtered images. The greyscale methods used had significant effect on the contrast of the image.The significance of this thesis is that it informs of the difficulties in developing surface inspection of steel defects due to several factors, such as environment and variation of defect shape, size, colour, and frequency. The work undertaken in this study has highlighted the need for a larger pilot line to further research both the capturing of the perfect image, and finding the most accurate detection and classification methods for each grade of steel.

AbstractA multi-mode electromagnetic stirring technology (MM-EMS) delivered by Danieli–Rotelec Company has been implemented in ArcelorMittal Gent CC2. This solution is able to control the liquid steel flows in CC mould by braking, accelerating or stirring them through the use of three different modes: EMLS, EMLA and EMRS. This paper presents the methodology followed in order to optimize the working of this new technology for improving the quality of products in terms of slivers defects. Different tools were developed and used by ArcelorMittal Maizières R&D to reach this objective: Numerical simulation with MagnetoHydroDynamics (MHD) tool to simulate the fluid flows in mould under the influence of magnetic fields, Submeniscus Velocity Control (SVC) tool to directly measure the liquid steel flows in the mould and finally some quality investigation tool like Automatic Surface Inspection System to detect defects directly on coils and qualify quality of products. Numerical and experimental approaches were associated to finally deliver to ArcelorMittal Gent steelplant an optimized actuator efficient for reducing defects in slabs and improving the final quality of products.
