The new CCM#12 unit will produce ultra-high-quality blooms in two different cross-sections: 450 × 530 mm and 395 × 410 mm. With the use of advanced and customized technologies, the project aims to achieve high metallurgical quality and precise dimensional accuracy.
Among the key technologies featured in the project is the Dynamic Mechanical Soft Reduction (DMSR) system, which enhances internal quality by controlling center porosity and segregation. In addition, the caster will be equipped with a Mechanical Hard Reduction (MHR) system with a torque of 250 kNm—the highest capacity ever implemented on a curved MSR caster—along with CONFLOW® stopper technology, a hydraulic oscillation unit, an air-water spray cooling system, and advanced electromagnetic stirring solutions (M-EMS, S-EMS, and two F-type EMS units). The system is further supported by a dedicated quenching unit and an independent bloom discharge system from a deep pit at -8.5 meters.
This technological setup has been designed to enable the production of large-section, high-quality blooms on a curved caster, meeting advanced quality requirements. Due to existing plant constraints, the strand spacing was limited to 2,500 mm and was optimized accordingly during the design phase.
The investment aims to increase Xiangtan Iron & Steel (Group) Co., Ltd.’s capacity for producing special bar quality (SBQ) steels for high value-added sectors such as automotive and green energy. For SMS group, the project further reinforces its leadership in technically challenging bloom caster projects. Moreover, with this project, the company will achieve the largest bloom cross-section among its global references in operation.
The parties aim to achieve all project objectives through continued collaboration in engineering, procurement, and commissioning processes.
