"This is another domestic first product developed by us - 174mm high-end extra thick chrome molybdenum steel plate, a total of 11 pieces, which will replace imports and be exclusively used in the manufacturing of ammonia synthesis reactor, the core device of a key technical innovation project in Jiangsu!" On September 5, on the production line of Wugang Company of Hegang Group, when seeing a batch of steel plates to be loaded and delivered to customers, Li Yangbing, a research and development personnel of the Ministry of Science and Technology, was proud.
The requirements of this product can be called "the most stringent in history" among such steel plates. As the ammonia synthesis reactor in this project needs to be used under extreme conditions such as high temperature, high pressure and hydrogen corrosion, it has extremely strict requirements for the required steel materials, and is "the most stringent in history" for the production and research and development of this type of steel plate. At the early stage of the customer's project design, Wugang Company actively gave full play to its technical advantages, combined with the scientific research team tailored for the project, deeply connected with users, and designed high-end extra thick steel plates for them to meet the personalized needs of the project. In the process of research and development, in view of the objective reality that the simulated post weld heat treatment process temperature and inspection technology difficulty of steel plates are the most stringent in the industry and the international leading level in this thickness range, Wugang increased its technical innovation efforts, innovatively designed rolling and heat treatment processes, and overcame the common technical problem of poor low-temperature impact energy parameters at the full thickness interface of ultra-thick steel plates after simulated welding for a long time at high temperature, The whole process strictly controlled the process technology and quality management, and finally created a high-end extra thick chromium molybdenum steel plate with 100% flaw detection qualification rate and performance qualification rate and Wugang characteristics. The technical indicators of the products were at the international leading level, and won praise from customers.
