Method for water-cooling slabs |
摘要 |
A method for water-cooling slabs by dipping and a water vessel used for said method. Slabs cooled by this method yield steel sheets with a minimum of scabs and uneven gloss. Slabs are dipped in water such a way that their larger faces are the upside and underside thereof. Dipping is accompanied by water injection (at a flow rate of 10-150 L/m<2>.min) toward the underside of slabs. The direction of water injection is perpendicular or oblique to the underside of the slabs. The position of water injection is 30-500 mm away from the underside of the slabs. In the case of water-cooling Cr-containing slabs (Cr 5-30 wt%), the slabs are conditioned such that their surface temperature is 500 DEG C or above before dipping and the dipping lasts until the surface temperature decreases to 400 DEG C or below. <IMAGE> |
