Recently, Jiugang Hongxing Co., Ltd. successfully completed a batch of stainless steel wire rod rolling tasks with a specification of 5.5mm. The quality of the produced wire rod is stable, and all indicators meet the relevant standard requirements. This is another important achievement of the refining and rolling mill in optimizing product structure and technological innovation. It not only enriches the product variety and enhances the competitiveness of the enterprise in the stainless steel market, but also lays a solid foundation for further expanding the high-end steel market.

Austenitic stainless steel wire rod has high strength and toughness, and requires a large rolling force during rolling. Its good ductility is prone to surface quality problems such as scratches and wrinkles during the rolling process. In addition, austenitic stainless steel is prone to intergranular corrosion at high temperatures, which requires extremely strict equipment accuracy and process control, and requires overcoming a series of technical difficulties.

Previously, due to the complex rolling process and high technical difficulty, Jiuquan Iron and Steel Hongxing Co., Ltd.'s refining and rolling plant has been in the exploratory stage in the field of stainless steel rolling. In order to achieve batch rolling of austenitic stainless steel wire rods, the factory has established a special technical research team to conduct extensive research and preparation work based on the characteristics of austenitic stainless steel, optimize rolling process parameters, adjust equipment accuracy, and strengthen quality monitoring, providing strong guarantees for the smooth rolling of the entire batch.

During the rolling process, in order to ensure temperature uniformity, technicians use advanced heating equipment to quickly and uniformly heat austenitic stainless steel billets, avoiding local overheating or undercooling. At the same time, by setting up temperature monitoring devices and providing real-time feedback on temperature information, the rolling process is always carried out at an appropriate temperature.

Reasonable rolling speed is crucial for reducing the difficulty of rolling austenitic stainless steel. The factory controls the rolling speed within a reasonable range based on factors such as the size of the billet, temperature, and equipment performance. In practical operation, the rolling speed can be dynamically adjusted through a computer control system based on real-time parameters such as rolling force and temperature to achieve the best rolling effect. After multiple experiments and adjustments, the factory has successfully overcome a series of technical difficulties and achieved stable rolling of the entire batch of 5.5mm stainless steel wire rods. The product quality has reached the expected target, and key indicators such as surface smoothness, dimensional accuracy, and product performance meet market demand.
