Structural features of horizontal continuous casting mold

The formation of the primary green billet shell at the molten steel inlet of the horizontal continuous casting mold copper sleeve is affected by the static pressure of the molten steel in the tundish, and the violent vortex motion is formed here due to the oscillating action of the billet, so the heat conduction is mainly concentrated at the front end of the copper sleeve , In the 150mm length from the separation ring, the heat transfer accounted for 60% to 80% of the total heat transfer of the crystallizer. Therefore, the horizontal continuous casting mold should adopt a multi-stage and multi-stage type, that is, the front section uses a copper sleeve and the rear section uses a graphite sleeve; the front section has a larger inverted taper and the rear section has a smaller inverted taper. Because graphite has self-lubricating properties at high temperatures, and the length of the copper sleeve that is easy to bond with the blank shell is very short, it can ensure that the drawing resistance of the entire mold inner sleeve is small.
