Oubotong expert technical service enters Huaigang

As a benchmark enterprise in the domestic special steel field, Jiangsu Huaigang attaches great importance to product quality and technological innovation throughout the entire production process. In this training, Huaigang broke down departmental barriers and organized core personnel in key areas such as production, research and development, and quality control to participate throughout the entire process, building a collaborative learning pattern of "management coordination+technical deep cultivation". This high level of participation not only reflects Huaigang's urgent need for material analysis technology, but also confirms Oubotong's professional reputation in the field of technical services in the steel industry - only training content that accurately matches industry pain points can win the deep recognition of the entire chain team of the enterprise.

In response to the various macro defects discovered during the low magnification inspection of steel (continuous casting billets, finished products) that Huaigang is concerned about, Teacher Ning Mei explained in detail the main contents of the low magnification inspection standards, including sampling requirements, inspection surface processing roughness, cold and hot acid corrosion methods, low magnification defect rating methods, etc., emphasizing the importance of low magnification inspection in controlling the product quality of steel from the source of steelmaking and continuous casting! At the same time, by displaying high-quality macroscopic morphology photos of various defects on the low magnification test piece, it explains in detail how to sample and fracture at the defect sites of the low magnification test piece (such as various cracks, pores, inclusions, looseness, shrinkage, etc.), and use scanning electron microscopy to observe and analyze the microscopic morphology characteristics of various defect fractures, in order to determine the nature and cause of the defects; Perform energy spectrum composition analysis on various large inclusions and precipitates. Technical training from macro to micro, from theory to practice, combined with the analysis and detection of quality problems inherited from the original defects of steel billets to subsequent products, as well as customer quality objection analysis cases, helps Huaigang technicians establish a comprehensive analysis concept from macro defect identification, micro feature analysis, and defect cause tracing of products.

Teacher Ning Mei elaborated on the importance of failure analysis methods, causes, and division of responsibilities through multiple failure analysis cases of steel products such as gear steel, bearing steel, pipeline steel, wear-resistant steel, etc. This includes macroscopic observation (location, morphology), macroscopic photography, understanding of production technology, processing and usage conditions, sampling location and quantity, composition analysis (including routine, residual, five hazards, gas), microscopic analysis of fracture surface, relative analysis of defects and normal parts, if necessary, sampling of normal parts for relevant performance testing, analysis of product usage environment and stress, etc. Through comprehensive analysis, accurate conclusions are finally drawn.

By adopting a combination of practical case teaching and practical thinking, this model has helped technical personnel at Huaigang to shift from vague responsibility allocation for quality issues to providing accurate basis, and from solving problems afterwards to preventing risks beforehand. It has provided strong technical support for the future production and research and development of higher quality and high-end steel products for the enterprise.

The two-day technical training was successfully completed, and the participants from Huaigang gave high praise and praise: the training content focused on technical difficulties in production, research and development, testing, and other aspects, especially the combination of electron microscopy application and failure analysis, which solved the technical problem of "knowing how to use equipment but not deep analysis" before; Customized seminars and training on product quality analysis have enabled technical personnel from various departments such as production, research and development, and quality inspection to clarify their future control directions and practical methods. This professional and practical technical training not only strengthens the collaborative cooperation between OPPO and Huaigang, but also conveys OPPO's brand proposition of "always putting customer needs at the core" through a technology empowered service model.

As a professional service provider in the field of material analysis, Obotong's "Expert Technical Service Journey" activity has been ongoing for many years, always adhering to the concept of "going deep into customer sites, connecting theory with practice, assisting in comprehensive analysis, solving various problems, and solving problems for customers". It spans across the country and continues to go deep into various steel enterprises across the country, providing customized technical training, equipment maintenance, problem diagnosis and other services. The successful completion of the technical training at Huaigang Station is not only a reflection of Oubotong's technical strength, but also an extension of its brand value. In the future, Oubotong will continue to deepen its cultivation in fields such as steel, automobiles, and new energy. With more precise instrument and equipment advantages, more advanced microscopic analysis technology, and more accurate customized services, it will work together with customers to solve quality problems and build a path of high-quality industrial development.
