Yan Ling integrated her patriotic feelings and desire to serve the country into the great cause of the strategy of "maritime power" and into the great struggle to create history. She led the team to make new contributions in the new era and new journey, and handed over a new answer sheet worthy of the country and the nation!
Yan Ling used the open day to give popular science lectures to the public.
As a party member, Yan Ling has always had the heart of a child, adhered to the aspiration of serving the country, led the technological progress of the industry, promoted the localization of high-end marine steel, and made positive contributions to China's steel and shipbuilding industry ranking among the world's advanced ranks. She has won more than 20 honorary titles such as the first prize of metallurgical scientific and technological progress, the first prize of Liaoning Provincial Science and Technology Progress, the gold medal of the World Invention Exhibition, the gold medal of the National Invention Exhibition, and the honorary titles of "National May 1st Scarf Medal", "March 8th Red Flag Bearer of Liaoning Province", "Excellent Scientific and Technological Worker of Liaoning Province" and so on.
Do not forget to follow the original intention of the party and build a maritime power. In the past 10 years, Yan Ling has presided over the research and development of nine series of more than 200 marine varieties through the certification of the International Classification Society, the world's first products 4, 53 key varieties to fill the domestic gap, the country took the lead in developing a number of high-end products that seriously restrict the technological progress of China's offshore equipment, applied to a number of world first, national first projects, including the world's first ultra-deepwater drilling platform "Blue Whale I", the first self-designed and built military icebreaker, etc. They are not only a symbol of the strength of Angang steel products, but also the responsibility of "big country heavy weapons".
Study hard and be a leader in innovative research and development
From the development of China's first shipbuilding board for the first 10,000-ton giant ship in the 1950s, to the supply of the first shallow sea oil production platform, to the supply of the first LEG liquid cargo cryogenic ship, the first ocean-going icebreaker, the first jack-up drilling platform, to the deep-water semi-submersible drilling platform Offshore Oil 982, the first corrosion-resistant steel demonstration tanker, to the realization of the "Offshore Jumbo" 20,000 TEUs super large container ship supply, Angang has always practiced the central corporate responsibility and responsibility. Become the most complete, widest and highest level steel enterprise in China for shipbuilding and offshore steel certification.
Behind these dazzling achievements, it is inseparable from the first-class research and development team of Angang Steel, and the unrepentant efforts of Yan Ling, director of the Ship plate research office of the Offshore Steel Research Institute. As the discipline leader of the "State Key Laboratory of Metal Materials and Their Applications for Marine Equipment", the chief expert of the Angang Shipbuilding Steel Leading Program, and a professor-level senior engineer, Yan Ling has undertaken more than 30 national science and technology support plans for the "Eleventh Five-Year Plan" and "Twelfth Five-Year Plan", the "Thirteenth Five-Year Plan" key research and development programs and more than 30 major projects at the provincial and ministerial levels.
On December 3, 2020, the VL4-4MOD low-temperature steel for LPG transport marine, developed by the State Key Laboratory of Metal Materials and Applications for Marine Equipment, achieved its world premiere. The advent of this product marks that the ANGANG ship plate has broken through the limits in terms of low temperature resistance, product thickness and strength, and can be used all over the world. Not only that, Yan Ling led the team to achieve the leapfrog development of Angang steel ship plate, completed the challenge goal of localization of high-end materials, provided high-end steel materials for China's super large oil tankers, container ships, luxury cruise ships, drilling platforms and other offshore "giants", and became the trump card "main force" supporting China's marine equipment manufacturing.
Spare no effort, fight in the steel front
Bearing hardships is the political essence of communists. More than 20 years ago, Yan Ling graduated from university with the number one professional results. As a child of Angang Steel, she took over the baton in the hands of her father and continued to contribute her light and heat to the construction of Angang Steel. Out of the university door, she did not choose a comfortable working environment, but went deep into the production line, took the initiative to ask for a shift internship, and tracked the production experiment on the spot, which was three years.
Suddenly, she has been working in Angang for 27 years, from a girl with a dream, to now she has white hair on her sideburns. Time is changing, what remains unchanged is her inner dedication to the cause, and the unremitting pursuit of the Angang spirit of "innovation, truth-seeking, hard work and dedication".
A party member, a banner. For more than 20 years, she has led the team to take root in the field and immerse herself in the laboratory, designing plans, tracking experiments, analyzing and summarizing scientific research results. Shipbuilding industry is well known as "bitter, dirty, tired", in the three years of service of the demonstration tanker, she went to the remote ship repair island in the south several times to conduct on-site service investigation, endured the pungent smell of oil and gas, and went down the vertical ladder of less than one foot wide to more than ten cargo tanks below the deck to measure, sample and analyze one by one, and finally obtained the first-hand data of China's real ship corrosion resistant steel. Behind a number of core technology breakthroughs, carrying her unremitting efforts.
The integration of production, education and research has achieved the country's heavy weapon
The need of the country is the direction of research and development. In the face of the need to import high-end materials in China, the cost of equipment manufacturing has been greatly increased, and the autonomy and controllability of materials are poor, Yan Ling accurately grasped the direction, declared a series of blank varieties as major scientific and technological projects at the provincial and ministerial levels and companies, and focused on tackling key problems. She united well-known universities, research institutes and offshore users to form a "production, study and research" team, conquered a number of high-end marine steel varieties, filled the domestic gap, successfully used in a number of major marine engineering projects, and achieved the first domestic launch.
In 2013, ciMC Raffles City, China's largest offshore engineering company, designed the "Blue Whale One" platform and prepared to select F-class ultra-high strength steel in the most critical parts. This design is the first time in the world. At that time, CIMC was facing foreign product monopolies and technical blockades, and the cost of imported steel was extremely high, which would cause a significant increase in the cost of the entire project, and the delivery time could not be guaranteed. If the construction period is delayed, the economic losses can be as high as hundreds of thousands of dollars per day.
Faced with this dilemma, CIMC Raffles was impatient and set its sights on domestic steel mills. After investigation, they found that only Angang Steel has this ability. After in-depth communication with the ANGANG team, the two sides signed a supply agreement. CIMC Raffles city wants ANSC to deliver the steel plate within 3 months.
After receiving the task, Yan Ling quickly threw herself into the research. People familiar with scientific research work know that the research and development of high-end products requires a cycle from material design, process formulation, production, to performance evaluation. After a few rounds, the performance was always abnormal and fluctuating, and the emotions of the players could not help but be frustrated. At this time, Yan Ling, as the backbone of the team, constantly cheered and encouraged everyone, and made key innovations and optimizations in the research plan with solid theoretical and practical experience. From the laboratory to the scene, to the inspection room, she fought continuously, analyzed and checked nearly a hundred parameters, and finally found the cause of performance fluctuations. The new material has finally been successfully developed! Angang Steel has become the only steel enterprise in Asia with F-class offshore steel supply qualifications, helping the mining of "combustible ice" in the ultra-deep waters of the South China Sea to succeed.
Accelerate the upgrading and be the pioneer of scientific and technological effectiveness
The avenue is simple, and the hard work is essential. Ship plate and marine engineering steel account for more than 40% of the production capacity of Angang steel medium and thick plate, with its high output and multi-variety, it has become the key to the effectiveness of angang steel's four medium and thick plate production lines. As the technical leader of the research and development of steel for marine engineering of Angang Steel Ship Plate, Yan Ling will focus on improving the added value of products and increasing the market share of high-end products.
Container marine high-strength ultra-thick anti-cracking steel plate is currently the world's most high-end products in the field of marine steel, which is still blank in China. The monopoly of technology and products formed by Japan and South Korea has led to a great reduction in the competitiveness of China's box ship market.
In the face of the urgent needs of the market, Yan Ling led the R&D team to devote herself to the core technology of anti-cracking steel. The production of extra-thick, ultra-wide anti-crack steel is an extreme challenge, both in terms of technical level and equipment capabilities. With solid theoretical knowledge and rich practical experience, she has broken through a number of key technical bottlenecks.
After eight months of research, Yan Ling led the R&D team to develop a full range of ultra-high and strong anti-crack steel plates with the largest thickness for the first time in China, and passed the certification of multinational classification societies. In the competition with JFE, POSCO and other internationally renowned steel companies, it exclusively won the bid for the supply order of 20,000 boxes of super-large containers with excellent comprehensive performance, and realized the localization demonstration application of this high-end material for the first time. Since then, they have successively undertaken more than ten orders for the supply of containers under construction, such as 17,000, 22,000 and 24,000 boxes. Angang Steel's domestic market share of this variety has reached more than 90%. In the past ten years, the cumulative effectiveness of new steel products for offshore equipment she has presided over has reached 240 million yuan.
Xiong Guan Man Dao is really like iron, and now he steps forward from the beginning. 2021 is the opening year of the "14th Five-Year Plan". Yan Ling will, as always, integrate her patriotic feelings and desire to serve the country into the great cause of the strategy of "maritime power" and into the great struggle to create history. The team she led made new contributions to the new era and new journey, and handed over a new answer sheet worthy of the country and the nation!
