In the 21st century, steel products will remain the most critical irreplaceable structural and functional material with the most significant output and the most comprehensive coverage in human society. The pace of structural adjustment of the world's metallurgical industry is accelerating, and the production focus will shift from developed countries to developing countries. At present, our country is in the process of industrialization. The continuous and rapid development of various sectors of the national economy and industrial upgrading has put forward higher requirements on the variety and quality of steel products. Therefore, speeding up the structural adjustment of my country's metallurgical industry will be of great significance.
هنوز شکافی در توسعه-گالوانیزه گرم فولاد نواری در مقایسه با سطح جهانی در کشور من وجود دارد. بسیاری از خطوط تولید گالوانیزه داغ موجود در کشور من دارای معایبی هستند: فناوری عقب مانده، مصرف بالای روی، خروجی محصول کم، کیفیت پایین محصول، هزینه های تولید بالا، مصرف انرژی بالا، اقدامات حفاظت از محیط زیست ناکافی، و اغلب باعث آلودگی شدید محیط زیست شود. چنین خطوط تولیدی نمی تواند نیازهای کشور من را برآورده کند. نیازهای اقتصاد ملی برای اوج گرفتن. تعداد کمی از{2}}شرکتهای فولادی بزرگ دولتی میتوانند ورقهای گالوانیزه داغ-با کیفیت بالا برای لوازم خانگی و خودرو تولید کنند. بیشتر فناوریهای-گالوانیزه گرم مداوم برای ورقهای فولادی در مقیاس بزرگ در کشور من از ایالات متحده، ژاپن و اروپا با هزینه قابلتوجهی ارائه میشوند. این در یک سطح عمومی است، با بسیاری از سطوح مشابه و تکرارپذیری. ، بسیاری از فن آوری های بالغ. بسیاری از محصولات موجود و محصولات مشابه،-تکنولوژیهای پیشرفته، جدید و پیشرفته-، چند محصول-فناوری پیشرفته، و کمتر فناوریهای مستقل توسعه یافته وجود دارد. فناوری اصلی را نمی توان به طور کامل تسلط یافت و توانایی توسعه و تولید انواع جدید وجود ندارد.
On the other hand, my country's self-developed hot-dip galvanizing process and technology conversion rate are low, and it isn't easy to form an industry. Low integration of immature and imperfect system technology results is the crux of engineering and industrialization. These problems are mainly because the production technology and equipment development capabilities of hot-dip galvanized steel sheets for high-performance automobiles in my country lag behind the world's advanced level. Therefore, developing the production technology and equipment high-performance automobile hot-dip galvanized steel sheet is indispensable. Strengthen the system integration of results, promote the transformation and application of results, gradually increase the self-sufficiency rate of my country's high-performance hot-dip galvanized automotive sheet products, and promote the progress and development of technology in this field in my country. The large-scale modern continuous hot-dip galvanizing steel plate unit in my country is imported from different countries such as the United States, Japan, Europe, etc. Although its products are relatively similar, the production technology has its characteristics. Application and innovation are significant work in surface coating technology. This move will accelerate the shortening gap between my country and foreign countries, reduce repeated introductions, and realize the system integration of high-performance hot-dip galvanized steel technology and equipment scientific research results. Realize the transformation and application of results, and push our technology to the world.
The domestic production technology and equipment of hot-dip galvanized steel sheets for high-performance automobiles currently mainly rely on introducing advanced foreign technologies. Only Baosteel has conducted some product-specific research on the production and development of automobile sheets and other imports for high-performance automobiles. As a result, the enterprises of the hot-dip galvanized sheet production line is just pure production and use, failing to digest and absorb fundamentally and effectively develop and use innovations. As the earliest domestic research unit to enter the field of continuous hot-dip galvanizing of steel strips, the Central Iron and Steel Research Institute assisted WISCO in introducing and digesting the first domestic hot-dip galvanizing unit in the 1970s. During the subsequent "Seventh Five-Year Plan" and "Eighth Five-Year Plan" period, the Central Iron and Steel Research Institute completed the development and scientific research of Galfan and Galvalume alloy coatings. The Central Iron and Steel Research Institute subsequently carried out the localization of continuous hot-dip coating equipment for steel strips and coordinated with relevant domestic units to complete the localization of essential equipment such as air knives, welders, sunken rolls (used by Galvalume), and gas purification devices. In recent years, the Central Iron and Steel Research Institute has always adhered to the combination of advancement in scientific research and development in these fields and has successfully developed a regenerative reduction annealing furnace with a combustion efficiency of more than 70 percent ; developed and promoted continuous hot-dip galvanizing of wideband steel. The alloy coating technology is designed to complete the regenerative folding reduction annealing furnace and designed and developed a medium current density electrolytic degreasing technology, closely tracking the ZAM series products with the highest corrosion resistance currently abroad and completing the pilot test.
مؤسسه تحقیقاتی آهن و فولاد مرکزی دارای یک واحد آزمایشی با عرض 100 میلیمتر است که روی آن پوششهای آلیاژی GF، GL، و گرم-آلیاژ-Si با موفقیت توسعه مییابد. علاوه بر این، پژوهشکده مرکزی آهن و فولاد در حال حاضر شرایط آزمایشگاهی کاملی برای آزمایش آزمایشی محصولات مختلف گالوانیزه گرم- دارد.
در حال حاضر، توسعه فناوری و تجهیزات ورق گالوانیزه گرم-برای اتومبیلهای-با عملکرد بالا هنوز در چین نسبتا ضعیف است. واحدهای مرکزی داخلی درگیر در این زمینه مراکز بزرگ فناوری شرکت فولاد هستند و برخی از دانشگاه ها نیز در حال انجام اهداف آزمایشی یا آزمایشی هستند. فعالیت های علمی پژوهشی.
