In accordance with the Chairman’s directive of the “Eight Improvements” spirit, the company has been continuously increasing its efforts in the development and production of specialty steel. Recently, the company successfully smelted the new Gr60 steel billet, providing strong support for further market expansion and brand building.
Gr60 grade steel is the primary material used for fasteners such as bolts and nuts, and it has widespread applications in fields like construction, bridges, and machinery manufacturing. The sales team of Tiangang Company actively explored the market, promptly understanding customer needs, and formed a coordination mechanism with the steel mill, the technical center, and the production operations department to quickly arrange production plans. The technical team carefully formulated detailed process control points and closely followed the smelting process.
In the converter process at the steel plant, key steps such as controlling the final temperature, final composition, and deoxidation alloying were strictly controlled to ensure stable molten steel quality. The refining process precisely adjusted the steel composition, removed impurities, and improved the purity of the molten steel. During the continuous casting process, technologies such as mold electromagnetic stirring, final solidification electromagnetic stirring, and constant casting speed control were used to optimize the process comprehensively, stabilizing the mold surface and ensuring the internal quality of the cast billets. The success rate of smelting this grade of steel reached 100%, with no issues such as reheating or casting interruptions.
Using the successful production of Gr60 grade steel as an opportunity, the company will continue to leverage its technical and equipment advantages, strengthen team cooperation, face the market positively, and actively explore. By improving quality, expanding product lines, and building the brand, the company will continuously enhance its competitive edge for sustainable development.
