Primetals to modernize Zenith Steel billet caster
by Hans Diederichs
Chinese steel producer Zenith Steel Group Co., Ltd. (Zenith Steel) awarded an order to Primetals Technologies to modernize a 10-strand billet caster in its converter steel making plant #3 in Changzhou. The billet caster will be the first one worldwide to be equipped with the new SRD (Single-Roll DynaGap) segments. The SRD segment has been specially developed for use in the area of final solidification, and it enables the upper rolls to be pressed down individually onto the solidifying strand. This enables the final solidification point to be followed precisely. Technological packages like DynaPhase, Dynacs 3D and DynaGap SoftReduction 3D will further improve the internal billet quality with regard to center porosity and center segregation. Start-up of the modernized casting machine is expected for March 2020.
