A technology of low superheat casting for 150 mm x 150 mm billet by two rollers cooling has been put forward
that is the molten steel flowing out from tundish into mold through cooling turning rollers to reduce molten steel superheat and improve quality of casting billet. The results of numerical simulation for a 0. 45C steel by hydromechanics analysis software indicated that the superheat of molten steel through cooling roller reduced
the impact depth of molten steel flow in mold was up to 250 mm
it was available to break columnar crystal at forward position of solidification
moreover the molten steel flow field and temperature field in mold distributed homogeneously and the solidification condition of casting billet improved obviously.
