Be the first responsible person! ----------------------------------------------- The past ten years have been an era of great development for China's chemical industry. The emergence of many new processes, new products, and new equipment has also led to a great development in my country's chemical equipment, which has also promoted the rapid development of the petrochemical industry. Here we have collected and sorted out some of the achievements and breakthroughs made by my country's equipment companies in the large-scale and localization of equipment. Welcome everyone to share, discuss, and exchange, cheer for Made in China, and cheer for chemical equipment! ------------------------------------------------------ This batch of products was successfully rolled off the production line of Hegang Handan Iron and Steel Co., Ltd. on June 1. It is extreme specification 22x1700x12010mmX60 pipeline steel, totaling 84 tons. After testing, the product yield ratio, drop weight performance, plate shape quality and surface quality were all qualified. X60 pipeline steel is a high-grade pipeline steel, which is already very difficult to produce and roll. However, since the extreme specifications of this type of steel are not involved, production is even more difficult. In the face of customer requests, the Production and Manufacturing Department of Hegang and Handan Iron and Steel Co., Ltd. organized relevant technical personnel from the technical center, medium plate plant and No. 3 Steelmaking Plant to tackle key problems. They selected the rolling process parameters of products with similar specifications of the steel type, repeatedly modified and optimized them to determine the rolling plan, and made predictions in advance about possible problems during the rolling process and formulated corresponding treatment plans. ； Conduct a comprehensive and detailed inspection of key equipment such as the front and rear roller tables of the rolling mill, clear the upper and lower headers of the cooling control device, and add two cooling water control pumps to ensure the water supply, so that all equipment conditions can reach optimal status. During the production process, in order to ensure the drop weight performance, they reasonably allocated the reduction amount of each pass. This also laid the foundation for ensuring good organization and performance in the future. ； In order to ensure qualified conventional performance, they strictly stipulated key parameters such as final rolling temperature, cooling mode, cooling rate and final cooling temperature to obtain the necessary metallographic structure and mechanical properties of this type of pipeline steel. ； In view of the difficult-to-control plate shape, they appropriately reduced the rolling force in the final pass and increased the number of smoothing passes. They also made special provisions for the cooling water ratio and straightening parameters.
