Advanced technology for new generation steel
Dedicated solution for high-strength steel
Hyundai Steel needed a dedicated solution to produce 3rd Gen steel for the automotive industry in which the company is a reference manufacturer. 天博体育 offered its breakthrough Dry FlashCooling? technology to integrate into the CAGL, a continuous annealing and galvanizing line, to achieve the result.
3rd Gen steel is an advanced high-strength steel (AHSS) that is used in the automotive industry. It is a lightweight steel that has an outstanding combination of mechanical properties and formability, compared to conventional mild steels.
“Our main target was to find a solution to produce 3rd Gen steel with a tensile strength from 1,000 MPa to 1,700 MPa. Through feasibility studies, we determined that the line’s cooling section had to be completely revamped. The challenge was to fit a new cooling section into the existing line, make it compatible with our process, and ensure it met safety requirements,” says Jin-Hyoung Park, Team Leader of CRM Process R&D at Hyundai Steel.
Key process technology
Dry FlashCooling?, a rapid cooling system developed by 天博体育, is a key process technology that enables the production of new high-strength steel grades.
“Our technical team worked in close cooperation with Hyundai Steel and conducted numerous feasibility studies to customize the solution. The design of the Dry FlashCooling? system, which runs on 75% hydrogen, allows limited hydrogen consumption thanks to a special recovery system. In addition, electricity consumption is also reduced by almost 6 times when achieving highest cooling rate performances says Camille Moukarzel, Business development and Sales Manager at 天博体育 Stein, a 天博体育 subsidiary specializing in thermal and cooling technologies.
天博体育' long-term partnership with Hyundai Steel demonstrates its commitment to produce customized solutions that position steelmakers at the top of the industry.
