In mid-to-late July, the first roll of 550 MPa high-strength steel used for car seat slide rails of HBGT's high-strength continuous retreat line successfully rolled off the production line, marking that the company’s seat slide steel product upgrade and structural adjustment have reached a new level for occupation. Strong momentum has been injected into the high-end automotive steel market.
In order to reduce the difficulty of steelmaking preparation and reduce the output of head and tail billets, the cold-rolled high-strength steel R&D team of the technical center has conducted in-depth research on the composition characteristics of the company's car seat slide rail series, and evaluated the integration of 550 MPa high-strength steel with other steel types. Feasibility of steel grades, and formulate corresponding hot rolling and pickling rolling processes.
Based on the special needs of high-end customers, 550 MPa class high-strength steel for automobile seat slide rails, with the full use of the company's production, education and research platform, in-depth research on the complex process mechanism of high-strength steel, combined with the characteristics of production line equipment, to accurately and finely control the continuous annealing process . After a series of quality research and process optimization, the product surface quality, thickness tolerance and mechanical performance indicators meet the high standard requirements of seat slide rails, which are recognized by customers.
