Pilot Implementation of the Technology and Equipment for Feeding Cooling Inoculators Into the CCM Mold at Severstal

详细

In the steel production at the Severstal Cherepovets Metallurgical Combine, we conducted pilot tests of equipment and technology in the continuous casting and simultaneous application of slag-forming mixtures and inoculators as a fraction. We observed improvement in the macrostructure in the axial zone of the ingot as a consequence of a more intensive cooling, as well as by increasing the number of crystallization sites. As an alternative to the method of introducing discrete inoculators, we propose a method and develop equipment designed to deliver a continuous ribbon chiller in the mold of the continuous caster. We determine the main parameters of the equipment and technology for introducing the ribbon into the mold of the continuous caster.
