Hegang Tanggang first rolled the limit specification for automotive transmission shaft tube steel for users
Recently, the Hegang Tangshan 1580 production line was successfully used for the first time for a user of Jiangsu to roll 130 tons of ultra-wide and ultra-thin limit specification automotive transmission shaft tube steel TS500Z. The geometrical dimensions, surface quality and mechanical properties of the finished product were tested. Meet user standard requirements.
The TS500Z is mainly used in automotive transmission shafts and is a key component for power transmission of trucks in high-speed operation. These products require high yield strength, good toughness and good welding performance. Due to the product width requirement of 1450mm, the thickness requirement of 2.5mm, and the high strength, the plate type and surface quality requirements are extremely strict, and the production is difficult. At present, only a few steel enterprises in China can stably produce.
In order to successfully roll the ultra-wide and ultra-thin extreme specification steel grades, the production line technicians have consulted a large amount of literature and developed a perfect test plan based on many previous rolling experience. In order to ensure the stability of the rolling and the good plate shape of the coil, they have drawn up the range of temperature control of the slab through-rolling during rolling, the target range of the finishing rolling temperature, the selection of the descaling pass, and the speed of the coil. The setting, the use of process lubrication, the input of cooling water between the racks, and the control and intervention of the opening of the counter-spraying roller, the use of the side guides, the preparation of the production plan, etc., thus ensuring the smooth production. .
The successful launch of the automotive transmission shaft tube steel product marks the successful opening of the Hegang Steel Transmission Steel tube steel process and lays a solid foundation for the development of this type of steel.
