CCM 3 has an annual capacity of 2.8 million metric t of high-quality, high-strength steel grades. It will supply slabs for a 1,780 mm hot strip mill, complements the new Zhanjiang facility and is part of a second phase of site development with the aim to reach an annual steel plant capacity of 12.35 million metric t/a. Start-up of the new casting machine is expected for early 2021.
The continuous slab caster CCM 3 is similar to the previously supplied casting machines CCM 1 and CCM 2, allowing for interchangeability of equipment and employing the same automation concept and configuration, as well as the same operation and maintenance procedures. It is designed as a bow type caster with straight mold, a machine radius of 9.5 m and a metallurgical length of 37.2 m. It produce slabs in widths from 900 to 1,650 mm and thicknesses of 230 or 250 mm. The casting speed can be varied between 1 and 1.95 m/min. Steel grades to be produced include the whole spectrum of carbon steel, from ultra-low to high carbon, deep-drawing, structural, peritectic and HSLA grades, micro alloyed to high alloyed steels, as well as pipe, strip and silicon grades.
The casting machine has straight SmartMold cassette-type molds, DynaFlex mold oscillators, and DynaWidth for automatic adjustment of the slab width. DynaGap Soft Reduction ensures that the slabs have a consistently high interior quality. The strand guide is equipped with Smart Segments. The combination of the Dynacs 3D cooling model with internally cooled I-Star rollers offers maximum flexibility in the secondary cooling.
