Recently, the First Steelmaking Division of Jingye Group successfully produced two furnaces of pipeline steel L245M. The yield strength of the steel reached 245Mpa, adding a new member to the group's steel varieties.
In order to develop this variety, the steelmaking organization held production preparation and technical analysis meetings, planned in advance, carefully arranged, and formulated special production plans and process control points. The smelting process focuses on grasping the proportion of raw materials entering the furnace and ensuring composition indicators and temperature control comply with the requirements; the continuous casting process ensures the cooling effect of the sector section by maintaining the accuracy of the equipment and cleaning the water nozzle, stabilizing the casting machine speed, and achieving a 100% pass rate of low magnification and appearance quality of the cast slab; the technical department tracks collects and analyzes production data on site , provide technical support for production and lay a solid foundation for the release of new products.
L245M pipeline steel has excellent properties such as high strength, high toughness, sulfur resistance, and hydrogen resistance, so it can be used for a long time under high pressure and harsh environments. In addition, the steel also has good weldability and plasticity, which facilitates construction and installation. These stable and reliable properties can ensure the safe operation of pipelines and effectively reduce maintenance costs. Therefore, L245M pipeline steel is widely used in natural gas transmission straight seam welded pipes and other fluid transportation equipment.
The successful production of L245M pipeline steel not only enriches the group's product structure of steel varieties but also further enhances the group's market competitiveness.
In the future, Jingye Group will continue to uphold the belief of honest cooperation and the value of quality innovation, increase investment in research and development, take quality as the guide and customer as the center, and provide customers and the market with more diverse high-quality products and better all-round services serve.
