Product Details
The automatic core rod su***cing equipment is a crucial tool in the production of seamless steel pipes, serving to support the deformation of steel pipes during the manufacturing process. The quality of the core rod directly determines the production efficiency of the enterprise, the su***ce quality of the steel pipes, and the production costs. Approximately 50% or more of the production and maintenance costs of continuous tube mill equipment is attributed to the consumption, scrap, and replacement of core rods. The low service life of core rods is a significant technical challenge that is currently prevalent and urgently needs to be addressed in China's steel pipe manufacturing enterprises. The working conditions of core rods in seamless steel pipe production are extremely harsh, as they not only have to withstand significant radial rolling forces but also experience considerable friction between the core rod and the steel pipe. Fatigue cracks and wear are the main failure modes of core rods. When the online core rods exhibit severe cracks and wear, they must be replaced immediately to ensure the su***ce quality of the steel pipes and the safety of the rolling mill, significantly increasing the production costs of the enterprise and causing downtime. Therefore, repairing failed core rods not only saves production costs for the enterprise but also has great significance for resource conservation. Repairing failed core rods involves not only restoring their shape and dimensions but also requires that the repaired core rods achieve or even exceed the performance and service life of the original core rods. The role of core rods in seamless steel pipe production demands that they possess high impact toughness and high hardness to enhance their resistance to cracks and wear. However, if the core rod material has a high carbon content and poor weldability, welding cracks may easily occur during welding, and the bonding strength between the base material and the su***cing layer may be poor, leading to spalling of the wear-resistant working layer during the rolling process. Therefore, the remanufacturing equipment for core rods is extremely important. The su***cing machine produced by our company operates stably and fully meets the process conditions required for repair. With four heads working simultaneously, it greatly improves work efficiency, reduces overall working time, and lowers risks
